Anterior cruciate ligament (ACL) tears in National Football League (NFL) players are devastating injuries that take nearly a year to recover. Players that do return to sport have worse overall performance compared to pre-ACL tear. NFL players typically play regular season games on Sunday with the next game played on the following Sunday, allowing for 6 days between games. Deviation from the usual 6-day rest week has been proposed as a potential risk for ACL tear. The main objective of this study was to evaluate the risk of decreased rest or increased rest on ACL tear rates in NFL players. ACL injury data of NFL players from the 2012 to 2013 season and 2022 to 2023 season were gathered from publicly available sources. Player demographic data, position, age at time of injury, seasons played, injury mechanism, and playing surface type were recorded. Injuries were characterized as short, normal, or long week injuries. ACL tears that occurred during the preseason, postseason, or during week 1 were excluded. Descriptive statistics were calculated to report means, ranges, and percentages. Data were analyzed to determine statistically significant differences using Fisher's exact, chi-square, or one-way analysis of variance tests. A total of 524 ACL tears were recorded in NFL players during the study window. Note that 304 ACL tears were excluded and 220 fit inclusion criteria. Twenty-four ACL tears occurred during short weeks, 68 during long weeks, and 128 during normal weeks. Players were 1.8 times more likely to tear their ACL during a long week compared to a normal week ( p  < 0.001), and 1.5 times more likely to tear their ACL during a short week compared to a normal week ( p  = 0.02). The findings from this study suggest that deviation from the normal 7-day NFL week increases the risk of an ACL tear in NFL players when increasing or decreasing rest time. Further research exploring the impact of short and long rest times on player injury risk should be conducted to prevent season-ending injuries., Competing Interests: None declared., (Thieme.

Background: Osteochondral allograft transplantation (OCAT) has become a standard-of-care treatment option for patients with large symptomatic articular defects. Recent advances in allograft science and OCAT protocols have been reported to result in consistently robust outcomes after OCAT in the knee. However, only short-term comparisons have been reported, and analyses are lacking for treatment failure risk factors that account for confounding variables., Hypothesis: Midterm functional graft survival rate would exceed 80% for all OCATs combined, with consideration of risk factors for lower survivorship including older patient age, higher body mass index (BMI), tibiofemoral bipolar OCAT, and nonadherence to prescribed postoperative rehabilitation protocols., Study Design: Case series; Level of evidence, 4., Methods: Patients with outcome data available at ≥5 years after primary OCAT using high chondrocyte-viability (HCV) osteochondral allografts were analyzed according to 2 clinically relevant definitions: (1) initial treatment failure, defined by revision or arthroplasty surgery performed for the primary OCAT at any time point during the study period; and (2) functional graft failure, defined by documented conversion to arthroplasty after primary or revision OCAT at any time point during the study period. Analyses were used to assess outcomes for each definition, separately for age group, sex, obesity status, tobacco use, type of OCAT surgery, osteotomy status, concurrent ligament surgery status, and adherence to postoperative protocols. Kaplan-Meier analyses were used to assess differences in survival rates, and Cox proportional hazards models were used to assess risk factors and multivariable relationships with survival. Patient-reported outcome measures for pain, function, mobility, and satisfaction were also analyzed., Results: Analysis included 137 primary knee OCATs performed in 134 patients with a mean follow-up of 66 months (59 female, 75 male; mean age, 37.8 years; mean BMI, 28.5). The midterm (5- to 8-year) functional graft survival rate for patients undergoing primary OCAT in the knee using HCV grafts was 82% for all cases combined, ranging from 69% for tibiofemoral bipolar HCV OCATs to 89% for patellofemoral bipolar, 94% for multisurface unipolar, and 97% for single-surface unipolar. Initial treatment failure rates (revision or arthroplasty after primary OCAT) and OCAT nonsurvival rates (arthroplasty after primary or revision OCAT) were greater for older patient age, concurrent ligament reconstruction, tibiofemoral bipolar OCAT, and nonadherence to the prescribed postoperative rehabilitation protocols. When adjusted for patients' age, BMI, and tobacco use status, different surgery types did not demonstrate an increased risk for failure, while concurrent ligament reconstruction and nonadherence did. Patients who experienced functional graft survival after primary OCAT reported significantly greater improvements in PROMIS Physical Function and Mobility (Patient-Reported Outcomes Measurement Information System), International Knee Documentation Committee questionnaire, and Single Assessment Numeric Evaluation scores such that they were significantly higher at final follow-up as compared with patients who required arthroplasty. Patient-reported improvements in pain, function, and mobility exceeded minimal clinically important differences for ≥5 years after primary OCAT. When asked if they were satisfied with primary OCAT surgery, 76.2% of patients were very satisfied or satisfied with their results, while 8.5% were neutral and 15.4% were unsatisfied or very unsatisfied., Conclusion: With use of HCV osteochondral allografts, midterm (5- to 8-year) functional graft survival rates for patients undergoing primary OCAT in the knee were notably higher than previously reported midterm rates for traditional OCATs. When adjusted for patient characteristics, risk factors for nonsurvival included concurrent ligament reconstruction for knee instability and nonadherence to the prescribed postoperative rehabilitation protocols. Patients who experienced functional graft survival for ≥5 years after primary OCAT reported statistically significant and clinically meaningful improvements in pain, function, and mobility., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: J.L.C. has received intellectual property royalties, consulting fees, and research support from Arthrex; consulting fees from Bioventus, Boehringer Ingelheim, Collagen Matrix Inc, and Trupanion; research support from GE Healthcare, Collagen Matrix, Musculoskeletal Transplant Foundation, PCORI, Regenosine, and SITES Medical; and royalties from Musculoskeletal Transplant Foundation and Thieme.

Objectives: The primary focus of this study is to determine if rural methamphetamine positive patients experience longer hospital length of stays compared to urban methamphetamine positive patients following an orthopaedic trauma., Methods: Patients presenting with traumatic orthopaedic injuries and urine drug screen were categorized into urban, suburban, and rural cohorts found in the Rural Urban Commuting Area codes based on home residence zip codes. Demographic, injury, hospital stay, and follow-up data were collected from the medical records. Comparisons between cohorts were determined by Chi square, Fisher exact, unpaired t-Tests, or ranked sum tests., Design: A retrospective cohort analysis., Setting: Academic Level I Trauma Center., Patient Selection Criteria: Patient records were examined between January 2013 to January 2023 for a traumatic orthopaedic injury and a urine drug screen result at the time of presentation to an academic Level I trauma center., Outcome Measures and Comparisons: Methamphetamine use status, patient age at time of admission, sex, marital status, insurance status, home zip code, orthopaedic injury location, complications, if the patient underwent surgery for orthopaedic injuries, admission date, discharge date, and discharge location were measured., Results: 249 patients met inclusion criteria for this analysis. Methamphetamine positive patients are significantly more likely to be younger, more likely to have surgery for orthopaedic injuries, experience a medical complication, or be discharged to home or a rehabilitation facility compared to methamphetamine negative patients. Urban patients experienced a shorter length of stay compared to suburban and rural patients, regardless of methamphetamine use status. Patients with Medicare, military, workers compensation, or commercial insurance are significantly more likely to attend follow-up appointments than patients with Medicaid or self-pay., Conclusions: Methamphetamine positive patients overall do not experience a longer length of hospital stay compared to methamphetamine negative patients. Rural methamphetamine positive patients experience a longer length of hospital stay compared to urban methamphetamine positive patients., Competing Interests: Declaration of competing interest The author group has the following disclosures: Ashwin R.

Background: Osteochondral allograft (OCA) transplantation with or without labral reconstruction is considered a hip preservation surgical treatment option for young, active patients. This study aims to report early outcomes for use of OCA and labrum allograft transplants for patients treated for symptomatic femoral head chondral damage and/or acetabular labrum deficiency after implementation of a comprehensive joint restoration approach., Methods: 33 patients from a lifelong registry were included for analysis. Outcomes were compared for statistically significant ( p  < 0.05) differences based on graft preservation methodology (standard preservation [SP] vs. Missouri Osteochondral Preservation System [MOPS]), and based on surfaces treated (femoral head only, labrum only, or femoral head and labrum)., Results: Mean follow-up duration was 44.8 (range 12-95) months. Success was documented in 28 (84.8%) patients. For the SP cohort, successful outcomes were documented in 5 cases (50%), while all 23 MOPS cases (100%) were deemed successful at least 1 year after surgery. Hip preservation surgeries performed using MOPS grafts were associated with significantly ( p  = 0.001; OR = 47x) higher success rates, including significant and clinically meaningful improvements in PROMs at 1 and 2 years after surgery. Revision was performed in 2 patients in the SP cohort and failure requiring total hip arthroplasty was documented in 3 SP patients. Mean time to revision or failure was 23.6 (range 4-43) months. The surfaces treated were significantly associated with failure when comparing patients undergoing a femoral head OCA with or without labral reconstruction to those undergoing labral reconstruction only ( p  = 0.03; OR = 8.3x)., Conclusions: Patients with symptomatic femoral head cartilage loss and/or irreparable acetabular labrum deficiency undergoing femoral head OCA transplantation and/or labral reconstruction with meniscus allografts using MOPS-preserved tissues experienced statistically significant and clinically meaningful improvements in pain and function through at least 2 years after surgery., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: JLK: Receives IP royalties from: Arthrex Inc, Musculoskeletal Transplant Foundation; receives research support from AO Trauma, Arthrex Inc, Collagen Matrix Inc, DePuy, A Johnson & Johnson Company, Musculoskeletal Transplant Foundation, National Institutes of Health (NIAMS & NICHD), Orthopaedic Trauma Association, Purina, Regenosine, SITES Medical, U.S. Department of Defense; paid consultant for Arthrex Inc, Trupanion; receives publishing royalties, financial or material support from Thieme.BDC: Receives IP royalties from Globus Medical; paid consultant and paid presenter or speaker for KCI; receives stock or stock options from Surgeon Advisory Board and speaker for Curvafix; Paid consultant for Orthopediatrics; Paid Consultant for Invibio., Paid consultant for DePuy Synthes., RomTech; unpaid consultant for Osteocentric; paid consultant and receives research support from Synthes.All other authors declare that there is no conflict of interest.

Background: Female sex workers are disproportionately affected by sexual violence, which is associated with an increased risk of poor mental health outcomes, substance use, and decreased access to health resources. Understanding the pathways through which sexual violence impacts these outcomes can inform strategies that appropriately and effectively meet the health needs of sex workers., Methods: This study investigated the prevalence of sexual violence among female sex workers in Côte d'Ivoire, and the relationship between sexual violence and adverse mental health and substance use outcomes. We examined survey data from female sex workers recruited between November 2019 and May 2020 across five regions of Côte d'Ivoire using respondent driven sampling (RDS), as part of an integrated bio-behavioral survey. The primary exposure of interest was self-reported lifetime experience of sexual violence, and the main outcomes of interest included depression, suicidal ideation, counselling seeking, alcohol consumption, and substance use. Multivariable logistic regression models investigated associations between exposure to sexual violence and the key mental health and substance use outcomes of interest. For each outcome, a directed acyclic graph was developed to identify a minimally sufficient set of covariates for adjustment. Additional sociodemographic characteristics, experiences, and sex work-related behaviors were explored in descriptive analyses using crude and RDS adjusted estimates., Results: Out of 1,177 participants, 376 (31.9%; RDS weighted: 30.5%; 95% CI: 24.7, 36.3) reported having experienced sexual violence in their lifetime, and of those 31.9% (RDS weighted: 31.2%; 95% CI: 21.3, 41.1) had experienced sexual violence within the previous 12 months. Experience of sexual violence was associated with an increased odds of suicidal ideation (aOR: 1.95; 95% CI: 1.48, 2.55), illicit drug use in the last 12 months (aOR: 2.40; 95% CI: 1.50, 3.86), daily alcohol use (aOR: 1.63; 95% CI: 0.99, 2.67), and having spoken to a counselor or confidant (aOR: 1.90; 95% CI: 1.34, 2.68)., Conclusion: Findings confirm a high burden of sexual violence among female sex workers in Côte d'Ivoire, and a need to implement large structural changes that enable female sex workers to seek protection as well as health resources after experiencing sexual violence. This may include reform in the form of targeted social, clinical and mental health resources, along with community development opportunities., (© 2024. The Author(s).)

Objectives: To delineate the key factors associated with treatment success or failure for patients undergoing lower extremity osteotomies to address a spectrum of lower extremity joint and limb deformities at an Integrated Limb Preservation Center (ILPC)., Methods: Design: Retrospective cohort study. Setting: Level I Academic Trauma Center. Patient selection criteria: Patients of the ILPC with at least 1-year of follow-up data regarding previous surgery to correct trauma-or developmental-related deformities between January 1, 2005, and October 1, 2022. Outcome measures and comparisons: Patients were categorized first based on etiology (developmental vs. traumatic) and then based on the nature of deformity (joint, limb, nonunion). Treatment data, demographics including age, sex, body mass index (BMI), tobacco use history, insurance status, marital status, mental health history, and history of comorbidities, concurrent procedures, and post-operative infection, revision, reoperation, and bone healing status were extracted from the medical record and compared. Treatment failure was defined as conversion of the limb preservation surgery (ies) to amputation of any type., Results: 139 patients were included for analysis; 47 patients in the developmental-related cohort, and 92 patients in the trauma-related cohort. The treatment success rate in terms of preserving the affected limb for patients undergoing lower extremity osteotomies was 94.7 % for the developmental-related cohort and 92.4 % for the traumatic-related cohort. 57.4 % of patients in the developmental-related cohort and 59.8 % of patients in the trauma-related underwent unplanned secondary procedures Concurrent osteomyelitis debridement (p = 0.01) and postoperative infection (p = 0.049) were the only factors measured significantly associated with conversion to amputation., Conclusions: Patients undergoing osteotomies at an ILPC to address developmental-related or trauma-related joint and/or limb deformities experienced high short-term success (>90 %) with respect to preserving the affected limb. However, 56 % of patients required subsequent unplanned surgeries and improvements in PROMs were only statistically significant in patients with trauma-related deformities., Level of Evidence: III., Competing Interests: James L Cook receives research support from AANA; receives research support from AO Trauma; receives IP royalties, is a paid consultant and receives research support from 10.13039/100007307Arthrex, Inc; is a paid consultant for Bioventus; is a paid consultant for Boehringer Ingelheim; is a paid consultant and receives research support from Collagen Matrix Inc; receives research support from GE Healthcare; is on the editorial or governing board for the Journal of Knee Surgery; is a board or committee member for Midwest Transplant Network; is a board or committee member, receives IP royalties and research support from Musculoskeletal Transplant Foundation; receives research support from the 10.13039/100000002National Institutes of Health (NIAMS & NICHD); receives research support from OREF; receives research support from Orthopaedic Trauma Association; receives research support from PCORI; receives research support from Regenosine; receives research support from SITES Medical; receives publishing royalties, financial or material support from Thieme; is a paid consultant for Trupanion; and receives research support from U.S. Department of Defense.

Background: Racial minorities are more likely to develop type 2 diabetes and experience associated microvascular complications. Non-Hispanic Blacks and Hispanics initially present with more severe diabetic foot ulcers (DFUs) and peripheral artery disease (PAD), with an associated 10-fold increase in risk for lower extremity amputation within the first year after diagnosis. This study was designed to determine if race is associated with a failure to refer to specialists for DFU treatment, and the severity of DFU at the time of initial presentation., Methods: Patients were identified from the medical record based on a diagnosis related to diabetic foot complications between January 1, 2018, and June 1, 2023, in the family medicine, endocrinology, orthopaedic, or emergency clinics at a Midwest Academic Hospital serving rural and urban populations. Patients self-reported race, demographics, severity of ulcer based on Wagner ulcer scale at time of referral, eventual amputation status, and measures of social determinants of health including the national Area Deprivation Index (ADI) and Rural-Urban Commuting Area (RUCA) codes were manually extracted and analyzed for correlations with referral status., Results: A total of 597 patients were eligible for inclusion. Race was not associated with lower referral rates ( P > .99) or source of referral ( P  = .58) to specialty clinic and ulcer severity at initial examination ( P  = .34). Patients who initially presented to the emergency department had more severe ulcers ( P  = .016), and higher severity was significantly associated with lower limb amputation vs mild ulcers (odds ratio = 38.8, P  = .02). No significant differences in referral source or severity of ulcer at presentation were seen for sex, age, marital status, insurance type, rural status, ADI, time from referral to appointment, or eventual amputation., Conclusion: In this study, we found that patient race was not associated with severity of DFU at presentation or subsequent referral to a Midwest academic specialty orthopaedic clinic for care.

Background: Osteochondral allograft transplantation (OCAT) and meniscus allograft transplantation (MAT) have each become more commonly implemented for the treatment of young to middle-aged patients with complex knee pathology. Evidence regarding tibiofemoral OCAT in the setting of concurrent MAT is limited., Purpose/hypothesis: The purpose of this study was to characterize outcomes for femoral condyle OCAT with concurrent MAT (OCAT+MAT) in the ipsilateral compartment of patients after evidence-based shifts in practice. It was hypothesized that OCAT+MAT would be associated with successful outcomes characterized by statistically significant and clinically meaningful improvements in patient-reported outcome measures (PROMs) of knee pain and function in >80% of patients for at least 2 years after transplantation., Study Design: Case series; Level of evidence, 4., Methods: With institutional review board approval and documented informed consent, patients who underwent primary OCAT+MAT between 2016 and 2020 and enrolled in a lifelong registry for prospective collection of outcomes after OCAT were included. Patients with minimum 2-year follow-up data regarding complications, failures, adherence, and PROMs were analyzed. Patients who required OCAT and/or MAT revision or conversion to arthroplasty were defined as experiencing treatment failures., Results: A total of 23 consecutive patients (mean age, 37.1 years; mean body mass index, 28 kg/m 2 ; 14 men) met the inclusion criteria, with a mean follow-up of 51 months (range, 24-86 months). The initial treatment success rate was 78% based on 5 initial treatment failures, and the overall success rate was 83% based on a successful revision OCAT. All failures occurred in the medial compartment. Older patient age (42.2 vs 32.1 years; P = .046) and nonadherence to postoperative restriction and rehabilitation protocols ( P = .033; odds ratio, 14) were significant risk factors for treatment failure. All measured PROMs achieved significant improvements ( P < .001) and minimum clinically important differences at a minimum of 2 years postoperatively., Conclusion: OCAT+MAT was associated with successful short- to mid-term outcomes in 83% of cases. Evidence-based shifts in practice were implemented before the enrollment of this patient cohort. Older patients and those who were not adherent to postoperative restriction and rehabilitation protocols had a significantly higher risk for treatment failure and subsequent conversion to arthroplasty., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: J.P.S. has received research support from Arthrex, the United States Department of Defense, and Thieme; education payments from Elite Orthopedics; consulting fees from Medical Device Business Services, Arthrex, DePuy Synthes, Orthopedic Designs North America, and Smith+Nephew; nonconsulting fees from Synthes GmbH and Medical Devices Business Services; and royalties from Thieme.

Emerging evidence suggests that patients' behavioral health may influence outcomes after osteochondral allograft transplantation (OCAT). A comprehensive behavioral health program (BHP) including preoperative screening and education, and postoperative counseling and support, led by a health behavior psychologist was implemented for patients considering OCAT. We hypothesized that patients undergoing knee OCAT and enrolled in the BHP would have a significantly higher 2-year graft survival rate than those not enrolled. Prospectively collected data for patients undergoing knee OCAT enrolled in the lifelong outcomes registry were analyzed. Based on the timing of implementation of a comprehensive BHP to provide preoperative screening and education followed by postoperative counseling and support, BHP and no-BHP cohorts were compared. Treatment failure was defined as the need for either OCAT revision surgery or knee arthroplasty. The Kaplan-Meier method using log-rank tests compared cumulative survival rates. Multivariable Cox regression analysis was used to determine the effects of confounding variables on the influence of BHP enrollment on graft survival. A total of 301 patients were analyzed (no-BHP = 220 and BHP = 81). At 2-year follow-up, a significantly lower cumulative graft survival rate was observed for patients not enrolled in the BHP (68.2 vs. 91.4%; p  = 0.00347). Adjusting for sex, age, body mass index, tobacco use, tibiofemoral bipolar OCAT type surgery, and nonadherence, patients not enrolled in the BHP were 2.8 times more likely to experience OCAT treatment failure by 2 years after primary OCAT compared with patients in the BHP (95% confidence interval, 1.02-4.98; p  = 0.01). A comprehensive BHP contributes to significant improvements in 2-year graft survival rates following OCAT in the knee. Preoperative mental and behavioral health screening and support for shared decision-making regarding treatment options, in conjunction with patient and caregiver education and assistance through integrated health care team engagement, are beneficial to patients pursuing complex joint preservation surgeries.

Background: Osteochondral allograft transplantation (OCAT) can be performed without the need for blood-type matching or anti-rejection medications. However, other donor-recipient mismatch variables could influence outcomes. Therefore, it is critical to examine the impacts of sex and age mismatching on functional OCA survival., Methods: Prospectively collected data for patients undergoing primary knee OCAT enrolled in a lifelong outcomes registry were analyzed for functional OCA survival based on sex- and age-matched and -mismatched cohorts. Treatment failure was defined as the need for OCAT revision surgery or knee arthroplasty., Results: 162 donor-recipient pairs were analyzed; 57 (35.2%) were sex-mismatched and 89 (54.9%) were age-mismatched. Sex-mismatched OCATs were not associated with a significantly different cumulative graft survival rate when compared to sex-matched OCATs (78.9% vs 75.2% p = 0.324). Age-mismatched OCATs were not associated with a significantly different cumulative graft survival rate when compared to age-matched OCATs (71.6% vs 81.5% p = 0.398). When adjusting for sex, BMI, concomitant procedures, and surgery type, age-mismatched and sex-mismatched OCATs were not significantly associated with higher likelihood for treatment failure., Conclusion: By analyzing functional graft survival rates for donor-recipient sex- or age-mismatched OCAs following primary OCAT, the results of the present study support current donor-recipient matching protocols for OCA transplantation in the knee. Based on current evidence, donor-recipient blood-type, sex-, and age-matching are not required for safe and effective primary OCAT in the knee. However, further studies are imperative for defining modifiable variables that further optimize safety and outcomes while maximizing donor tissue quality, availability, access, and use., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: James P Stannard is a paid consultant and receives research support from Arthrex, Inc; is a paid consultant for DePuy, A Johnson & Johnson Company; is on the editorial or governing board for the Journal of Knee Surgery; receives research support from National Institutes of Health (NIAMS & NICHD); is a paid consultant for Orthopedic Designs North America; is a paid consultant for Smith & Nephew; receives publishing royalties, financial or material support from Thieme; and receives research support from the U.S. Department of Defense.

Background: Key populations (KP), including men who have sex with men (MSM), female sex workers (FSW), and transgender women (TGW), experience a disproportionate burden of HIV, even in generalized epidemics like South Africa. Given this disproportionate burden and unique barriers to accessing health services, sustained provision of care is particularly relevant. It is unclear how the COVID-19 pandemic and its associated restrictions may have impacted this delivery. In this study, we aimed to describe patterns of engagement in HIV prevention and treatment services among KP in South Africa and assess the impact of different COVID-19 restriction levels on service delivery., Methods: We leveraged programmatic data collected by the US President's Emergency Plan for AIDS Relief (PEPFAR)-supported KP partners in South Africa. We divided data into three discrete time periods based on national COVID-19 restriction periods: (i) Pre-restriction period, (ii) High-level restriction period, and (iii) After-high level restriction period. Primary outcomes included monthly total HIV tests, new HIV cases identified, new initiations of pre-exposure prophylaxis (PrEP), and new enrollments in antiretroviral therapy (ART). We conducted interrupted time series segmented regression analyses to estimate the impact of COVID-19 restrictions on HIV prevention and treatment service utilization., Results: Between January 2018 and June 2022, there were a total of 231,086 HIV tests, 27,051 HIV positive cases, 27,656 pre-exposure prophylaxis (PrEP) initiations, and 15,949 antiretroviral therapy initiations among MSM, FSW and TGW in PEPFAR-supported KP programs in South Africa. We recorded 90,457 total HIV tests during the 'pre-restriction' period, with 13,593 confirmed new HIV diagnoses; 26,134 total HIV tests with 2,771 new diagnoses during the 'high-level restriction' period; and 114,495 HIV tests with 10,687 new diagnoses during the after high-level restriction period. Our Poisson regression model estimates indicate an immediate and significant decrease in service engagement at the onset of COVID-19 restrictions, including declines in HIV testing, treatment, and PrEP use, which persisted. As programs adjusted to the new restrictions, there was a gradual rebound in service engagement, particularly among MSM and FSW. Towards the end of the high-level restriction period, with some aspects of daily life returning to normal but others still restricted, there was more variability. Some indicators continued to improve, while others stagnated or decreased., Conclusion: Service provision rebounded from the initial shock created by pandemic-related restrictions, and HIV services were largely maintained for KP in South Africa. These results suggest that HIV service delivery among programs designed for KP was able to be flexible and resilient to the evolving restrictions. The results of this study can inform plans for future pandemics and large-scale disruptions to the delivery of HIV services., (© 2024. The Author(s).)

Background: Key population HIV programmes in sub-Saharan Africa require epidemiological information to ensure equitable and universal access to effective services. We aimed to consolidate and harmonise survey data among female sex workers, men who have sex with men, people who inject drugs, and transgender people to estimate key population size, HIV prevalence, and antiretroviral therapy (ART) coverage for countries in mainland sub-Saharan Africa., Methods: Key population size estimates, HIV prevalence, and ART coverage data from 39 sub-Saharan Africa countries between 2010 and 2023 were collated from existing databases and verified against source documents. We used Bayesian mixed-effects spatial regression to model urban key population size estimates as a proportion of the gender-matched, year-matched, and area-matched population aged 15-49 years. We modelled subnational key population HIV prevalence and ART coverage with age-matched, gender-matched, year-matched, and province-matched total population estimates as predictors., Findings: We extracted 2065 key population size data points, 1183 HIV prevalence data points, and 259 ART coverage data points. Across national urban populations, a median of 1·65% (IQR 1·35-1·91) of adult cisgender women were female sex workers, 0·89% (0·77-0·95) were men who have sex with men, 0·32% (0·31-0·34) were men who injected drugs, and 0·10% (0·06-0·12) were women who were transgender. HIV prevalence among key populations was, on average, four to six times higher than matched total population prevalence, and ART coverage was correlated with, but lower than, the total population ART coverage with wide heterogeneity in relative ART coverage across studies. Across sub-Saharan Africa, key populations were estimated as comprising 1·2% (95% credible interval 0·9-1·6) of the total population aged 15-49 years but 6·1% (4·5-8·2) of people living with HIV., Interpretation: Key populations in sub-Saharan Africa experience higher HIV prevalence and lower ART coverage, underscoring the need for focused prevention and treatment services. In 2024, limited data availability and heterogeneity constrain precise estimates for programming and monitoring trends. Strengthening key population surveys and routine data within national HIV strategic information systems would support more precise estimates., Funding: UNAIDS, Bill & Melinda Gates Foundation, and US National Institutes of Health., Competing Interests: Declaration of interests SB has received funding from the US National Institutes of Health (NIH).

Background: Up to 80% of patients in the United States report dissatisfaction with pain management following orthopaedic surgery. Inadequate pain management is linked to negative outcomes, including increased costs, readmission rates, and chronic pain risk. Traditional pain management protocols often emphasise the biological components of pain, overlooking psychological and social. This systematic review addresses this gap by answering two key questions: (1) What factors are associated with increased risk of unsatisfactory pain management following orthopaedic surgery? (2) What are the key components of successful pain management protocols following orthopaedic surgery?, Methods: PRISMA guidelines were followed with a search of relevant online databases. Studies were included if they were in English, provided patient feedback/satisfaction with pain management (quantitative studies) or provided satisfaction with pain management or healthcare team feedback (qualitative studies) or explored patient variables associated with satisfaction with pain management., Results: Of the 845 articles screened, 27 met the inclusion criteria. Synthesis suggested that while perceived severity and duration of pain are often assumed to be the primary drivers of patient satisfaction related to pain management, patients with a sense of control over their pain reported higher satisfaction, regardless of actual pain level. History of opioid misuse, patient expectations, and patient mental health were associated with dissatisfaction., Conclusion: Pre-operative education and ongoing communication, particularly regarding patient risk-factors and multi-modal pain management strategies, appear to enhance patients' sense of control and satisfaction. Future research should explore whether individualised pre-operative education can improve satisfaction with post-surgical orthopaedic pain management., (© 2024 John Wiley & Sons Ltd.)

Meniscus allograft transplantation (MAT) is a proven treatment option for patients with symptomatic irreparable meniscus deficiency. When patients are adherent to prescribed postoperative restriction and rehabilitation protocols, outcomes after MAT are considered good to excellent. However, nonadherence to standard protocols is common and can be associated with undesirable outcomes and patient dissatisfaction. Based on demonstrated safety for early weight-bearing following MAT in conjunction with significant advances in graft preservation and surgical techniques, our joint preservation center implemented a shift in practice toward accelerated weight-bearing following MAT and designed this study to test the hypothesis that accelerated rehabilitation would be associated with superior adherence, patient-reported outcomes, and patient satisfaction, without diminishing patient safety, when compared with standard rehabilitation. Patients were included for analyses when they had undergone fresh or fresh-frozen MAT using a double bone plug technique for treatment of medial or lateral meniscus deficiency and had at least 1-year treatment outcomes recorded. The results of this study revealed that patients who were prescribed accelerated rehabilitation after MAT were significantly more adherent than patients who were prescribed standard rehabilitation and reported statistically significant and clinically meaningful improvements in knee pain and function for at least 1-year following MAT, whereas those in the standard cohort did not. While not statistically different, treatment failure rate was lower in the accelerated rehabilitation cohort when compared with the standard rehabilitation cohort (11 vs. 29%). Importantly, initial outcomes for revision MAT were associated with short-term success in all the patients who opted for this option in the study population. These data suggest that accelerated weight-bearing after MAT is safe, promotes patient adherence, and is associated with statistically significant and clinically meaningful improvements in patient-reported knee pain and function at early and mid-term follow-up., Competing Interests: • J.P.S. is a board or committee member for the American Orthopaedic Association; is a board or committee member for AO Foundation; is a board or committee member for AO North America; is a paid consultant and receives research support from Arthrex, Inc; is a paid consultant for DePuy, Johnson & Johnson Company; is on the editorial or governing board for the Journal of Knee Surgery; is a board or committee member for Mid-America Orthopaedic Association; receives research support from National Institutes of Health (NIAMS & NICHD); is a paid consultant for Orthopedic Designs North America; is a paid consultant for Smith & Nephew; receives publishing royalties, financial or material support from Thieme; and receives research support from U.S. Department of Defense.• C.W.N. is a board or committee member for AAOS; is a board or committee member for American Orthopaedic Society for Sports Medicine; receives other financial or material support from AO Foundation; is a paid presenter or speaker for Arthrex, Inc; is on the editorial or governing board, receives publishing royalties, financial or material support from Arthroscopy; is a board or committee member for Arthroscopy Association of North America; is a paid consultant for Guidepoint Consulting; and is a paid presenter or speaker for Vericel, Inc.• J.L.C. receives research support from AANA; receives research support from AO Trauma; receives IP royalties, is a paid consultant and receives research support from Arthrex, Inc; is a paid consultant from Bioventus; is a paid consultant for Boehringer Ingelheim; is a paid consultant and receives research support from Collagen Matrix Inc; receives research support from GE Healthcare; is on the editorial or governing board of the Journal of Knee Surgery; is a board or committee member for Midwest Transplant Network; is a board or committee member, receives IP royalties and research support from Musculoskeletal Transplant Foundation; receives research support from National Institutes of Health (NIAMS & NICHD); receives research support from OREF; receives research support from Orthopaedic Trauma Association; receives research support from PCORI; receives research support from Regenosine; receives research support from SITES Medical; receives publishing royalties, financial or material support from Thieme; is a paid consultant for Trupanion; and receives research support from U.S. Department of Defense.• K.R. and C.C. have no conflict of interest to disclose., (Thieme.

Background: Barriers stemming from Social Determinants of Health (SDOH) are known to contribute to higher rates of complications, poor patient adherence to treatment plans, and suboptimal outcomes following orthopaedic care. While SDOH's impact has been characterized, interventions to address SDOH-related inequities in orthopaedics have not yet been optimized., Purpose: The objective of the present systematic review was to identify and synthesize current peer-reviewed literature focused interventions to address SDOH-related inequities to develop optimal mitigation strategies that improve outcomes for orthopaedic patients., Methods: A systematic search of PubMed, OVID, and CINAHL identified articles that referenced SDOH and an intervention to address inequities., Results: After screening 419 studies, 19 met inclusion criteria. Studies commonly looked at the impact of insurance policy change on the rate of the population with active insurance and associated use of elective surgery. Nine studies found that policy changes generally increased the rate of insured patients, though inequities remained for younger and racial minority patients. The relative paucity of literature in conjunction with methodological differences among studies highlights the need for further development and validation of effective interventions to address SDOH-related inequities in orthopaedics., Conclusions: Insurance expansion was the focus of the majority of included articles, finding that expansion is associated with higher rates of insured patients undergoing elective and emergent procedures, however, gaps remain for young patients and racial minorities. Further research is needed to determine effective healthcare team, healthcare system, and policy-level interventions that overcome SDOH-related barriers to optimal care and outcomes for orthopaedic patients., Level of Evidence: Level-II., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: James L Cook receives research support from AANA; receives research support from AO Trauma; receives IP royalties, is a paid consultant, and receives research support from Arthrex, Inc; is a paid consultant for Bioventus; is a paid consultant for Boehringer Ingelheim; is a paid consultant and receives research support from Collagen Matrix Inc; receives research support from GE Healthcare; is on the editorial or governing board of the Journal of Knee Surgery; is a board or committee member for Midwest Transplant Network; is a board or committee member, receives IP royalties, and receives research support from Musculoskeletal Transplant Foundation; receives research support from National Institutes of Health (NIAMS & NICHD); receives research support from OREF; receives research support from Orthopaedic Trauma Association; receives research support from PCORI; receives research support from Regenosine; receives research support from SITES Medical; receives publishing royalties, financial or material support from Thieme; is a paid consultant for Trupanion; and receives research support from U.S. Department of Defense.

Purpose of Review: Big Data Science can be used to pragmatically guide the allocation of resources within the context of national HIV programs and inform priorities for intervention. In this review, we discuss the importance of grounding Big Data Science in the principles of equity and social justice to optimize the efficiency and effectiveness of the global HIV response., Recent Findings: Social, ethical, and legal considerations of Big Data Science have been identified in the context of HIV research. However, efforts to mitigate these challenges have been limited. Consequences include disciplinary silos within the field of HIV, a lack of meaningful engagement and ownership with and by communities, and potential misinterpretation or misappropriation of analyses that could further exacerbate health inequities. Big Data Science can support the HIV response by helping to identify gaps in previously undiscovered or understudied pathways to HIV acquisition and onward transmission, including the consequences for health outcomes and associated comorbidities. However, in the absence of a guiding framework for equity, alongside meaningful collaboration with communities through balanced partnerships, a reliance on big data could continue to reinforce inequities within and across marginalized populations., (© 2024.

Context: Over 200,000 anterior cruciate ligament (ACL) injuries occur in the United States each year. While many patients choose to pursue ACL reconstruction (ACLR), the impact of social determinants of health (SDOH) on outcomes is unclear., Objective: The purpose of this study was to review and synthesize current literature to determine the impact of SDOH on outcomes following ACL reconstruction., Data Sources: A systematic search of PubMed, CINAHL, Medline, PsychINFO, and Scopus was completed., Study Selection: Articles reporting outcomes following ACLR were included if they discussed at least one SDOH and provided ACLR failure rates., Study Design: Systematic review., Level of Evidence: Level I., Results: After screening 712 studies, 13 were found that met inclusion criteria and were analyzed. Studies commonly examined the correlations between race, income, location, education, and insurance on outcomes following ACLR. Three studies found that the ACL revision risk for Black patients compared to White patients ranged from 0.23 to 0.78, while the revision risk for Hispanic patients compared to White patients ranged from 0.7 to 0.83. One study reported finding that the odds ratio of revision for the White patients was 1.32. Another study reported no difference in revision risk based on race. Patients living in urban areas were found to have improved outcomes compared to rural areas (Mean IKDC (Urban 85.3 vs Rural 81.87) and Tegner-Lysholm (Urban 88.26 vs Rural 84.82)). Lower socioeconomic status was correlated with decreased post-operative functional scores (KOOS, Marx and IKDC)., Conclusion: Several SDOH such as White race, rural location, and low socioeconomic status may be independently correlated with worse ACLR outcomes in the form of increased revision rates or worse post-operative functional scores. However, further research is needed to better elucidate the degree of impact and interconnectedness of SDOH domains on ACLR patient outcomes., Competing Interests: Steven DeFroda is a board or committee member for American Orthopaedic Society for Sports Medicine; is a paid presenter or speaker for AO North America; receives research support for 10.13039/100007307Arthrex, Inc; is on the editorial or governing board of Arthroscopy; is a board or committee member for Arthroscopy Association of North America; and receives publishing royalties, financial or material support Springer.

Background: Estimating the size of key populations, including female sex workers (FSW) and men who have sex with men (MSM), can inform planning and resource allocation for HIV programs at local and national levels. In geographic areas where direct population size estimates (PSEs) for key populations have not been collected, small area estimation (SAE) can help fill in gaps using supplemental data sources known as auxiliary data. However, routinely collected program data have not historically been used as auxiliary data to generate subnational estimates for key populations, including in Namibia., Objective: To systematically generate regional size estimates for FSW and MSM in Namibia, we used a consensus-informed estimation approach with local stakeholders that included the integration of routinely collected HIV program data provided by key populations' HIV service providers., Methods: We used quarterly program data reported by key population implementing partners, including counts of the number of individuals accessing HIV services over time, to weight existing PSEs collected through bio-behavioral surveys using a Bayesian triangulation approach. SAEs were generated through simple imputation, stratified imputation, and multivariable Poisson regression models. We selected final estimates using an iterative qualitative ranking process with local key population implementing partners., Results: Extrapolated national estimates for FSW ranged from 4777 to 13,148 across Namibia, comprising 1.5% to 3.6% of female individuals aged between 15 and 49 years. For MSM, estimates ranged from 4611 to 10,171, comprising 0.7% to 1.5% of male individuals aged between 15 and 49 years. After the inclusion of program data as priors, the estimated proportion of FSW derived from simple imputation increased from 1.9% to 2.8%, and the proportion of MSM decreased from 1.5% to 0.75%. When stratified imputation was implemented using HIV prevalence to inform strata, the inclusion of program data increased the proportion of FSW from 2.6% to 4.0% in regions with high prevalence and decreased the proportion from 1.4% to 1.2% in regions with low prevalence. When population density was used to inform strata, the inclusion of program data also increased the proportion of FSW in high-density regions (from 1.1% to 3.4%) and decreased the proportion of MSM in all regions., Conclusions: Using SAE approaches, we combined epidemiologic and program data to generate subnational size estimates for key populations in Namibia. Overall, estimates were highly sensitive to the inclusion of program data. Program data represent a supplemental source of information that can be used to align PSEs with real-world HIV programs, particularly in regions where population-based data collection methods are challenging to implement. Future work is needed to determine how best to include and validate program data in target settings and in key population size estimation studies, ultimately bridging research with practice to support a more comprehensive HIV response., (©Talia Loeb, Kalai Willis, Frans Velishavo, Daniel Lee, Amrita Rao, Stefan Baral, Katherine Rucinski.

Background: Osteochondral allograft transplantation (OCAT) allows the restoration of femoral condyle osteochondritis dissecans (OCD) lesions using an osteochondral unit. When OCD lesions are irreparable, or treatments have failed, OCAT is an appropriate approach for revision or salvage surgery. Based on its relative availability, cost-effectiveness, lack of donor site morbidity, and advances in preservation methods, OCAT is also an attractive option for primary surgical treatment for femoral condyle OCD., Hypothesis: OCAT for large femoral condyle OCD lesions would be highly successful (>90%) based on significant improvements in knee pain and function, with no significant differences between primary and salvage procedure outcomes., Study Design: Cohort study; Level of evidence, 3., Methods: Patients were enrolled into a registry for assessing outcomes after OCAT. Those patients who underwent OCAT for femoral condyle OCD and had a minimum of 2-year follow-up were included. Reoperations, treatment failures, and patient-reported outcomes were compared between primary and salvage OCAT cohorts., Results: A total of 22 consecutive patients were included for analysis, with none lost to the 2-year follow-up (mean, 40.3 months; range, 24-82 months). OCD lesions of the medial femoral condyle (n = 17), lateral femoral condyle (n = 4), or both condyles (n = 1) were analyzed. The mean patient age was 25.3 years (range, 12-50 years), and the mean body mass index was 25.2 kg/m 2 (range, 17-42 kg/m 2 ). No statistically significant differences were observed between the primary (n = 11) and salvage (n = 11) OCAT cohorts in patient and surgical characteristics. Also, 91% of patients had successful outcomes at a mean of >3 years after OCAT with 1 revision in the primary OCAT cohort and 1 conversion to total knee arthroplasty in the salvage OCAT cohort. For both primary and salvage OCATs, patient-reported measures of pain and function significantly improved at the 1-year and final follow-up, and >90% of patients reported that they were satisfied and would choose OCAT again for treatment., Conclusion: Based on the low treatment failure rates in conjunction with statistically significant and clinically meaningful improvements in patient-reported outcomes, OCAT can be considered an appropriate option for both primary and salvage surgical treatment in patients with irreparable OCD lesions of the femoral condyles., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: C.N. has received financial or material support from AO Foundation and Arthroscopy; education payments from Arthrex and Elite Orthopedics; consulting fees from Arthrex and Guidepoint Consulting; nonconsulting fees from Vericel, Arthrex, and Stryker; royalties from Arthroscopy; and hospitality payments from Synthes GmbH.

HIV-related stigma remains a significant barrier to implementing effective HIV treatment and prevention strategies in Nigeria. Despite the high uptake of peer support groups among people living with HIV (PLHIV) in Nigeria, the potential role of such peer support on the burden of internalized stigma remains understudied. To address this gap, we conducted a secondary analysis of the PLHIV Stigma Index 2.0, a socio-behavioral survey implemented by PLHIV led-organizations to assess the relationship between group membership and internalized stigma. Internalized stigma was measured using the Internalized AIDS-related Stigma Scale. Multinomial logistic regression was used to measure the association between self-reported engagement in peer support groups and internalized stigma adjusting for age, education, duration since HIV diagnosis, employment, disclosure status, and sex-work engagement. Of the 1,244 respondents in this study, 75.1% were engaged in HIV peer support groups. Over half (55.5%) and about one-fourth (27.3%) demonstrated low/moderate and high levels of internalized stigma, respectively. PLHIV engaged in HIV peer support groups were less likely to report both low/moderate (versus no) (adjusted odds ratio (aOR): 0.47 [95% CI: 0.27 to 0.81]; p = 0.006) and high (versus no) (aOR: 0.30 [95% CI: 0.17 to 0.53]; p < 0.001) levels of internalized stigma compared to those not engaged. In this study, the burden of internalized stigma is high among PLHIV in Nigeria. However, engagement in peer support groups appears to mitigate these stigmas. Stigma mitigation strategies to increase peer support may represent a critical tool in decreasing sustained HIV treatment gaps among PLHIV in Nigeria., (© 2023.

Treatment options for symptomatic cartilage loss in the ankle are not consistently effective. This study documents initial outcomes for patients undergoing bipolar OCAT in the ankle after advances in tissue preservation, transplantation techniques, and patient management strategies were implemented. Patients were prospectively enrolled into a registry designed to follow outcomes after OCAT in the ankle. Fourteen patients were included for analyses (12 primary OCAT, 2 revision OCAT). Four patients underwent Bipolar OCAT (tibia, talus) and 10 Bipolar+ OCAT (tibia, talus, fibula). Short-term (median follow-up 43, range 13-73 months) success was documented for 13 patients. Radiographic assessments indicated OCA integration and maintenance of joint space in 12 patients. Statistically significant (p < .030) and clinically meaningful improvements in AAOS and VAS pain scores were noted at 3 months, 6 months, 1 year, and 2 years following OCA transplantation when compared to preoperative measures. For patients that were nonadherent to postoperative restriction and rehabilitation protocols, all 1-year postoperative PROs were significantly lower (p < .050) than for patients who were adherent. The successful outcomes documented in 13 of 14 patients in conjunction with significant and clinically meaningful improvements in patient-reported measures of pain and function support OCA transplantation as an appropriate treatment option in indicated patients. These improvements in outcomes were associated with advances in OCA preservation, preimplantation treatment, transplantation techniques, and patient management strategies, suggesting this shift in practice be considered for OCA transplantation in the ankle., (Copyright © 2023 the American College of Foot and Ankle Surgeons.

Background: Symptomatic acetabular labral insufficiency in young, active patients is often treated with labral repair or reconstruction using fresh-frozen allografts. However, fresh-frozen tendon allografts do not have tissue or material properties that closely mimic acetabular labral fibrocartilage. Recent studies suggest meniscal allografts may be a better biomechanical, geometric, and material alternative for acetabular labrum reconstruction (ALR)., Hypothesis: Patients undergoing open ALR using fresh meniscus allograft transplants (MAT) will have better outcomes than those using fresh-frozen tendon allografts transplants (TAT) when comparing initial treatment success, diagnostic imaging assessments, and patient-reported pain and function scores., Study Design: Cohort Study., Methods: With IRB approval, patients undergoing ALR with either TAT or MAT were included when initial (>1-year) outcomes data related to treatment success, pain, and function were available. In addition, a subcohort of patients underwent magnetic resonance imaging at least 6-months after surgery to evaluate allograft healing., Results: Initial success rate, defined as no need for ALR revision or conversion to total hip arthroplasty (THA), was 88.9% for the entire group (n = 27, TAT = 5, MAT = 22) with 1 (20%) patient in the TAT cohort and 2 patients (9.9%) in the MAT cohort undergoing THA. In the MAT cohort, significant improvements were documented for physical function and pain scores at 1 year and final follow-up (FFU)(mean 26.8 months). Improvements in pain and function were noted at 1-year, but not at FFU (mean 59.6 months) in the TAT group. MRIs completed at least 6 months after labrum reconstruction showed improved allograft integrity and integration in the MAT cohort over the TAT cohort., Conclusion: For acetabular labrum reconstructions, MAT was associated with a higher initial success rate, superior patient reported outcomes, and subjectively better MRI findings when compared to TAT., (© 2024 Professor P K Surendran Memorial Education Foundation.

Surgical reconstruction is recommended for symptomatic posterior cruciate ligament (PCL) deficiency. While anatomic double-bundle PCL reconstruction (PCLR) has been reported to be associated with biomechanical and clinical advantages over other methods, there is still debate regarding the optimal technique for tibial positioning and fixation. Based on reported advantages and disadvantages, we employed two tibial fixation techniques, transtibial (TT) and tibial inlay (TI) for anatomic double-bundle PCLR with technique selection based on body mass index, comorbidities, and primary versus revision surgery. This study aimed to compare clinical outcomes following PCLR utilizing either TT or TI techniques to validate relative advantages, disadvantages, and indications for each based on the review of prospectively collected registry data. For 37 patients meeting inclusion criteria, 26 underwent arthroscopic TT PCLR using all-soft- tissue allograft with suspensory fixation in the tibia and 11 patients underwent open TI PCLR using an allograft with calcaneal bone block and screw fixation in the tibia. There were no significant preoperative differences between cohorts. Success rates were 96% for TT and 91% for TI with all successful cases documented to be associated with good-to-excellent posterior stability and range of motion in the knee at the final follow-up. In addition, patient-reported outcome scores were within clinically meaningful ranges for pain, function, and mental health after PCLR in both cohorts, suggesting similarly favorable functional, social, and psychological outcomes. Patient-reported pain scores at 6 months postoperatively were significantly ( p  = 0.042) lower in the TT cohort, which was the only statistically significant difference in outcomes noted. The results of this study support the use of TT and TI techniques for double-bundle anatomic PCLR in restoring knee stability and patient function when used for the treatment of isolated and multiligamentous PCL injuries. The choice between tibial fixation methods for PCLR can be appropriately based on patient and injury characteristics that optimize respective advantages for each technique., Competing Interests: • J.L.C. received research support from AO Trauma, received IP royalties and is a paid consultant for Arthrex, Inc; received research support from Collagen Matrix Inc; received research support from DePuy, A Johnson & Johnson Company; is on the editorial or governing board of the Journal of Knee Surgery; is a board or committee member for Midwest Transplant Network; is a board or committee member; received IP royalties and research support from Musculoskeletal Transplant Foundation; received research support from National Institutes of Health (NIAMS & NICHD); received research support from Orthopaedic Trauma Association; received research support from Purina; received research support from Regenosine; received research support from SITES Medical; received publishing royalties, financial, or material support from Thieme; is a paid consultant for Trupanion; and received research support from the U.S. Department of Defense.• J.P.S. is a board or committee member for the American Orthopaedic Association; is a board or committee member for AO Foundation; is a board or committee member for AO North America; is a paid consultant and receives research support from Arthrex, Inc; is a paid consultant for DePuy, A Johnson & Johnson Company; is on the editorial or governing board for the Journal of Knee Surgery; is a board or committee member for Mid-America Orthopaedic Association; receives research support from the National Institutes of Health (NIAMS & NICHD); is a paid consultant for Orthopedic Designs North America; is a paid consultant for Smith & Nephew; received publishing royalties, financial or material support from Thieme and received research support from the U.S. Department of Defense.• J.T., K.R., A.M., and J.B.deA.

Background: Knee osteochondral allograft transplantation (OCAT) has been associated with good short- to mid-term outcomes, however, treatment failures occur more frequently than desired. This study used data from a lifelong outcomes registry to analyze knee OCAT treatment failure rates, variables associated with knee OCAT treatment failures, and outcomes after revision or arthroplasty surgery for knee OCAT treatment failures., Methods: Patient outcomes were followed after knee OCAT performed using standard preservation (SP) or Missouri Osteochondral Preservation System (MOPS®) allografts. The study population consisted of patients undergoing primary OCAT with ≥ 2-year follow-up. For comparisons, the treatment failure population was defined by patients in the study population with documented treatment failure (revision or arthroplasty) with ≥ 2-year follow-up after failure. Functional graft survival was defined as no further need for revision surgery after primary or revision OCAT., Results: A total of 262 patients (n = 136 males; 51.9%) were analyzed. SP grafts were used for 59 cases and MOPS grafts were used for 203 cases. Treatment failure was documented in 61 cases (23.3%). MOPS grafts were 3.3 times more likely to be associated with functional graft survival. SP grafts, older patient age, higher BMI, tibiofemoral bipolar OCAT and non-adherence to the postoperative rehabilitation protocol were significantly associated with treatment failure., Conclusions: Knee OCAT resulted in functional graft survival at short- to mid-term follow-up in the majority (70-88%) of cases. In addition, revision of primary OCAT resulted in functional graft survival for at least 2 years after revision surgery in the majority (66%) of patients., Level of Evidence: 2, prospective cohort study., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Introduction: While the importance of patient adherence to treatment protocols is firmly accepted, a definition for adherence and mechanisms to address non-adherence are not well established. The goals of this study were to define adherence and identify barriers and enablers for adherence partnerships through the lens of the orthopaedic healthcare team., Methods: The qualitative study was designed using concepts from grounded theory. Eight focus groups, comprised of orthopaedic healthcare team members, were conducted to identify factors influencing orthopaedic patient adherence to treatment plans., Results: Healthcare team members identified a range of factors affecting patient adherence. Participants conveyed that patient non-adherence can be a deliberate decision but can also result from barriers faced by the patient. Synthesis of themes identified distinct phases of adherence and culminated in the creation of a preliminary model that encapsulates healthcare team and patient factors impacting adherence, which was entitled, The Barriers and Enablers to Treatment Adherence (BETA) Model., Conclusion: The study findings alleviate the patient from the sole burden of adherence, recognising the influences that the healthcare team and system have on patients' ability to adhere. The BETA model of patient adherence represents the first step to mitigating non-adherence by providing a foundation for programmatic research aimed at developing and evaluating interventions and management strategies that empower healthcare teams to effectively equip patients for adherence, leading to optimised patient outcomes following orthopaedic interventions., (© 2023 John Wiley & Sons Ltd.)

Treatment of symptomatic osteoarthritis (OA) is often complicated by comorbidities, which put patients at potentially higher risks following operative interventions. Management of these comorbidities is usually separate from orthopaedic care, with patients invited to return to their orthopaedic surgeon once surgical risk factors are better controlled. However, this practice can lead to disjointed care, resulting in uncertainty, mistrust, unmanaged pain, and dissatisfaction for patients. Integrated care teams provide an effective option for coordinated comprehensive nonoperative and preoperative management of patients with knee OA and medical comorbidities. The objective of this article is to summarize the process for implementation of an integrated program to manage patients with symptomatic knee OA and the initial outcomes at our institution as an example of the effects of integrated patient management in orthopaedics. At the author's institution, an integrated program was implemented, successfully addressing the unmet need for coordinated care for patients with bone and joint health problems and medical comorbidities. Patients who completed the full program experienced significant improvements in both pain and function. Potential applications for knee surgeons considering implementing integrated care models could include pre- and postoperative management programs, nonoperative management program, and programs seeking to meet key metrics such as improved readmission rates, patient satisfaction, or value-based care. For effective program implementation, careful planning with convenient referral mechanisms, leadership buy-in, and patient-centered communication protocols are required., Competing Interests: None declared., (Thieme.

Patient adherence with postoperative wound care, activity restrictions, rehabilitation, medication, and follow-up protocols is paramount to achieving optimal outcomes following knee surgery. However, the ability to adhere to prescribed postoperative protocols is dependent on multiple factors both in and out of the patient's control. The goals of this review article are (1) to outline key factors contributing to patient nonadherence with treatment protocols following knee surgery and (2) to synthesize current management strategies and tools for optimizing patient adherence in order to facilitate efficient and effective implementation by orthopaedic health care teams. Patient adherence is commonly impacted by both modifiable and nonmodifiable factors, including health literacy, social determinants of health, patient fear/stigma associated with nonadherence, surgical indication (elective vs. traumatic), and distrust of physicians or the health care system. In addition, health care team factors, such as poor communication strategies or failure to follow internal protocols, and health system factors, such as prior authorization delays, staffing shortages, or complex record management systems, impact patient's ability to be adherent. Because the majority of factors found to impact patient adherence are nonmodifiable, it is paramount that health care teams adjust to better equip patients for success. For health care teams to successfully optimize patient adherence, focus should be paid to education strategies, individualized protocols that consider patient enablers and barriers to adherence, and consistent communication methodologies for both team and patient-facing communication., Competing Interests: J.C. reports grant from Musculoskeletal Transplant Foundation, National Institutes of Health (NIAMS & NICHD), Purina, and U.S. Department of Defense, and royalties from Musculoskeletal Transplant Foundation and Theime, also consulting fees from Trupanion.

Patient treatment decisions for knee osteoarthritis (OA) are driven largely by the patient's physical examination and radiograph findings. Because multiple treatment options may be medically appropriate, it is imperative that the patient's voice be considered to better facilitate patient-centered treatment decisions. Concordance between physicians and patients on optimal treatment can vary, with few studies identifying the factors important to patients when making treatment decisions for knee OA. The goal of this analysis is to identify and synthesize subjective factors in the literature found to influence patient decision-making in a presurgical knee OA population, such that physicians and health care teams can become better equipped to help patients realize their specific treatment goals. This review was registered with PROSPERO and conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. A systematic search was completed in four databases for search terms related to knee OA and decision-making. Articles were eligible for inclusion when they discussed (1) patients' thoughts, feelings, goals, and perceptions that factored into treatment deliberation and decision-making; and (2) related to knee OA. Twenty-four articles were identified, 11 qualitative studies and 13 quantitative studies. Synthesis of the included articles revealed three main themes that drive patient treatment decisions: (1) individual catalysts to pursue treatment including pain and mobility limitations, (2) interpersonal factors including social networks and clinician trust, and (3) risks versus benefits assessment including patients' beliefs and expectations. Only a few studies looked at nonoperative treatment decisions, and no studies looked at cohorts considering knee preservation surgeries. This study was completed to synthesize literature related to patient treatment decisions for nonoperative and surgical management of knee OA, finding that patients consider multiple subjective factors when choosing whether to move forward with treatment. Understanding how patients' beliefs determine their preferences for treatment can improve shared decision-making., Competing Interests: K.R.: None.

The sexual and reproductive health needs of female sex workers (FSW) are often understudied and underserved in the context of HIV-related research in countries across Sub-Saharan Africa and West Africa. We assessed the lived experiences of FSW across Côte d'Ivoire to characterize unmet reproductive health needs and opportunities to address them. From February-August, 2020, ENDA Santé, Côte d'Ivoire conducted 75 in-depth interviews and 15 focus group discussions with FSW and community informants in five cities in Côte d'Ivoire. Themes that emerged included the inconsistent use of contraception services, a history of unintended pregnancies, and experiences of stigma at public healthcare facilities. Opportunities to increase the impact of both SRH and HIV services included strengthening existing HIV and family planning service integration for FSW. Taken together, the results highlight the importance of addressing the unmet reproductive health needs of FSW to both optimize the HIV response and increase the delivery of human-rights affirming sexual and reproductive health services for sex workers., (© 2023.

Background: Patient nonadherence with prescribed rehabilitation protocols is associated with up to 16 times higher likelihood of treatment failure after osteochondral allograft transplantation (OCA) and meniscal allograft transplantation., Hypothesis: Patients who completed counseling with an orthopaedic health behavior psychologist as part of an evidence-based shift in practice at our institution would have significantly lower rates of nonadherence and surgical treatment failure versus patients who did not participate in counseling., Study Design: Cohort study; Level of evidence, 2., Methods: Patients in a prospective registry who underwent OCA and/or meniscal allograft transplantation between January 2016 and April 2021 were included for analysis when 1-year follow-up data were available. Of 292 potential patients, 213 were eligible for inclusion. Patients were categorized based on whether they participated in the preoperative counseling and postoperative patient management program: no health psych group (n = 172) versus health psych group (n = 41). Nonadherence was defined as documented evidence of a deviation from the prescribed postoperative rehabilitation protocol., Results: In this cohort of patients, 50 (23.5%) were documented to be nonadherent. Patients in the no health psych cohort were significantly more likely to be nonadherent ( P = .023; odds ratio [OR], 3.4). Tobacco use (OR, 7.9), higher preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference score, lower preoperative PROMIS Mental Health score, older age, and higher body mass index were also significantly associated with nonadherence ( P < .001 for all). Patients who were nonadherent with the prescribed postoperative rehabilitation protocol during the first year after transplantation were 3 times more likely ( P = .004) to experience surgical treatment failure than those who were adherent. Overall, 26.2% of patients in the no health psych group experienced surgical treatment failure versus 12.2% in the health psych cohort., Conclusion: Data from the present study suggest that preoperative counseling with a health behavior psychologist is associated with an improved rate of patient adherence and a lower proportion of surgical treatment failure after OCA and meniscal allograft transplantation. Patients who remained adherent to the postoperative protocol were 3 times more likely to have a successful short-term (≥1 year) outcome., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: J.P.S. has received research support from Arthrex; consulting fees from Arthrex, DePuy, Orthopedic Designs North America, and Smith & Nephew; and royalties from Thieme.

Introduction: Treatment monitoring after meniscus allograft transplantation (MAT) is challenging. Ultrasonographic (US) imaging has been proposed as a modality that may allow for treatment monitoring after MAT, but has yet to be clinically validated for this purpose. The objective of this study was to assess the capabilities for serial US imaging during the first year after surgery to predict short-term MAT failure., Methods: Patients who had undergone Meniscus-only or Meniscus-Tibia MAT for treatment of medial or lateral meniscus deficiency were prospectively evaluated by US imaging at various time points after transplantation. Each meniscus was evaluated for abnormalities in echogenicity, shape, associated effusion, extrusion and extrusion with weightbearing (WB)., Results: Data from 31 patients with a mean follow-up of 32 ± 16 (range, 12-55) months were analysed. MAT failure occurred in 6 patients (19.4%) at a median time point of 20 (range, 14-28) months with 4 (12.9%) converted to total knee arthroplasty. US imaging was effective for assessing MAT extrusion and imaging with WB demonstrated dynamic changes in MAT extrusion. US characteristics that were significantly associated with higher likelihood for MAT failure included abnormal echogenicity, localised effusion, extrusion with WB at 6 months, and localised effusion and extrusion with WB at 1 year., Conclusions: US assessments of meniscus allografts at 6 months after transplantation can effectively determine risk for short-term failure. Abnormal meniscus echogenicity, persistent localised effusion and extrusion with weightbearing were associated with 8-15 times higher odds for failure, which occurred at a median of 20 months post-transplantation., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: James L.

Objective: Female sex workers (FSW) and adolescent girls and young women (AGYW) face a disproportionately high risk of HIV in South Africa. Oral preexposure prophylaxis (PrEP) can avert new infections, but its effectiveness is linked to consistent use. Early discontinuation of PrEP in this population is high, but less is known about longitudinal patterns of PrEP use, including patterns of re-initiation and cycling., Design: Longitudinal descriptive analysis of routine program data., Methods: Between 2016 and 2021, 40 681 FSW and AGYW initiated PrEP at TB HIV Care, the largest PrEP provider to this population in South Africa and were included. Using survival analyses and group-based trajectory modeling, we described patterns of initiation, discontinuation, re-initiation, and cycling., Results: Total initiations increased over the life of the program for both FSW and AGYW. About 40% of FSW [0.41, 95% confidence interval (CI) [0.40-0.42]] and AGYW (0.38, 95% CI [0.37-0.38]) remained on PrEP at one month. FSW were more likely to restart PrEP, however <10% restarted PrEP within a year of initiation. Three latent trajectory groups of PrEP use were identified for FSW (low use, early cycling, and ongoing cycling) and two for AGYW (low use and ongoing cycling). Persistence was negatively associated with initiation among AGYW, but there was no clear relationship among FSW. Those initiating later in the program and older women had a reduced risk of discontinuation., Conclusions: Persistence on PrEP was low, but cycling on and off PrEP was common, with early missed visits and inconsistent, but ongoing use. A push to increase PrEP initiations needs to factor in readiness and persistence support, to achieve public health impact., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Purpose: To compare outcomes after whole-surface osteochondral allograft (OCA) transplantation using shell grafts for treatment of patellofemoral joint lesions with respect to surfaces treated and OCA preservation method., Methods: With institutional review board approval and informed consent, patients were prospectively enrolled into a registry to follow outcomes after OCA transplantation. Patients who received patellofemoral shell OCA to treat the entire articular surface of the patella, trochlea, or both, and with a minimum of 2-year follow-up data, including patient-reported outcome measures (PROMs), failures, and complications, were included. Functional graft survival was determined based on patients returning to functional activities without need for OCA revision or arthroplasty surgery and calculated using the formula: 100% - (%revision + %failure). Minimum clinically important differences were determined based on previously validated data. Outcomes were compared based on differences in graft preservation methodology (Missouri Osteochondral Preservation System [MOPS] or standard preservation [SP]) and based on surfaces treated (patella, trochlea, or both)., Results: Fifty-eight patients met inclusion criteria. Mean age was 36.7 years (range 15-60 years) and mean body mass index was 28.9 (range 18-42). OCAs stored using SP methods were transplanted in 12 patients, mean follow-up was (66.1 months; range 54-70 months): OCAs stored using MOPS methods were transplanted in 46 patients, mean follow-up was (44.8 months; range 24-60 months). Graft survival rate at final follow-up was significantly greater (P = .025) for MOPS OCAs (98%) compared with SP OCAs (75%), whereas 2-year functional graft survival rates (MOPS 98% vs SP 83%; P = .1) were not. Reoperation rate was significantly greater (P = .0014) for SP cases compared with MOPS cases. PROMs showed statistically significant and clinically meaningful improvements through 4 years after unipolar patella, unipolar trochlea, and bipolar patellofemoral OCA transplantation using MOPS grafts. Unipolar patella OCA transplantations were associated with significantly more reduction in pain and significantly better PROMs at 1-year compared with unipolar trochlea and bipolar patellofemoral OCAs., Conclusions: OCA transplantation using MOPS shell grafts for unipolar and bipolar patellofemoral resurfacing was associated with statistically significant and clinically meaningful improvements from preoperative levels of pain and function. The 2-year functional graft survival rate was 83% in the SP group and 98% in the MOPS group, such that MOPS was associated with better short-term outcomes than SP methods when performing OCA transplantation using shell grafts for patellofemoral lesions. Patients who received unipolar patella allografts reported the best outcomes in terms of pain and function., Level of Evidence: Level III, retrospective analysis of registry data., (Copyright © 2022 Arthroscopy Association of North America.

Background: Unicompartmental tibiofemoral bipolar osteochondral allograft transplantation (OCAT) with meniscal allograft transplantation (MAT) has not historically been associated with consistently successful outcomes for treatment of knee articular cartilage defects with meniscal deficiency., Hypothesis: Primary OCAT and MAT using fresh tissues will be associated with successful short-term outcomes based on statistically significant and clinically meaningful improvements in pain and function in the majority of patients., Study Design: Case series; Level of evidence, 4., Methods: Patients were prospectively enrolled into a registry for outcomes after OCAT and MAT. Patients included those who underwent primary OCAT and MAT using Missouri Osteochondral Preservation System (MOPS)-preserved allografts for treatment of large bipolar tibiofemoral articular cartilage defects with meniscal deficiency and had a minimum of 2-year follow-up data., Results: A total of 76 patients (n = 52 male; 68%) met inclusion criteria (mean follow-up, 52 months). The mean age was 41.1 years (range, 15-69 years), and the mean body mass index was 28.9 (range, 17-46); 48 patients underwent another OCAT in addition to the unicompartmental bipolar tibiofemoral OCAT and MAT; 23 patients (30.3%) were documented to be nonadherent to the prescribed postoperative restriction and rehabilitation protocol. The initial success rate (>2 years) was 77.6%, with 8 patients (10.5%) undergoing revision and 9 (11.8%) converting to arthroplasty. Variables associated with an increased risk for treatment failure (revision or arthroplasty) included ipsilateral osteotomy ( P = .046; odds ratio [OR] = 3.3), ipsilateral concurrent procedure ( P = .0057; OR = 5.5), and nonadherence ( P = .0009; OR = 7.2). None of the patients undergoing revision surgery required arthroplasty at the time of data analysis such that the overall success rate for primary and revision unicompartmental bipolar OCA plus MAT was 88.2%. There were statistically significant ( P < .0001) and clinically important improvements for all patient-reported outcomes at each annual follow-up time point., Conclusion: Unicompartmental tibiofemoral bipolar OCAT and MAT can result in successful short-term outcomes (2-6 years) and satisfaction in the majority of patients (78%). Primary MOPS-preserved OCAT with MAT for treatment of femoral condyle and tibial plateau articular cartilage defects with concurrent meniscal deficiency was associated with statistically significant and clinically meaningful improvements in patient-reported measures of pain and function.

Objective: To assess key demographic and psychosocial variables that may be associated with non-adherence to clinic visits following orthopaedic trauma injuries to patients in an urban and rural population., Methods: This retrospective review included all operative and non-operative patients presenting to a Level I academic trauma center serving an urban and rural population in the Midwest following an orthopaedic injury. The study tracked patient attendance to scheduled orthopaedic trauma follow-up clinic visits after a scheduled visit in the clinic following a trauma-related injury., Results: Data were obtained for 5816 unique orthopaedic trauma patients who had 21,066 post-treatment follow-up visits scheduled. 1627 "no-show" appointments were recorded. Factors associated with no-shows included male sex, age between 26 and 35 years, self-reported race other than white, employment listed as disabled, household income below $25,000, education less than a high school level, uninsured, Medicaid insured, and relationship status reported as single., Conclusions: In the present study, key demographic and psychosocial factors were significantly associated with patient adherence to scheduled follow-up appointments after treatment for orthopaedic trauma. Identifying patients at higher risk for nonadherence will allow healthcare teams to educate patients, providers, and staff, link patients to resources to enhance adherence, and work with their institutions to develop and implement protocols for improving adherence to follow-up appointments., Competing Interests: Conflicts of Interest and Source of Funding Emily Leary is on the editorial or governing board of JISAKOS and The Journal of Knee Surgery.

This prospective randomized clinical trial assessed a novel device for initial management of knee range of motion (ROM), pain, and function after total knee arthroplasty (TKA). Primary TKA patients with preoperative ROM of at least 5° to 115° were randomized to initial knee motion management: Mizzou BioJoint Flex-novel motion-assistive device with prescribed physical therapy or standard physical therapy-prescribed physical therapy. ROM, pain score, and knee injury and osteoarthritis score for joint replacement (KOOSjr) were obtained preoperatively and 2 weeks, 6 weeks, and 3 months postoperatively. Patient satisfaction for both cohorts and subjective assessments of the MBF device were assessed at 3 months. Readmissions, reoperations, and complications were assessed through 1 year. Nineteen patients were randomized to each cohort, with no significant preoperative differences in demographics, pain score, KOOSjr score, or ROM. Six SPT (31.6%) and 3 MBF (15.8%) patients failed to regain preoperative ROM ( p  = 0.044). One SPT (5.3%) and eight MBF (42%) patients exceeded 125° ROM ( p  = 0.019) by 3 months. Total ROM ( p  = 0.039), pain ( p  = 0.0068), and function ( p  = 0.0027) were significantly better for MBF at 3 months. MBF patients reported significantly higher satisfaction (mean, 9.4 ± 1.1 vs. 8.0 ± 1.8, respectively; p  = 0.0084). One patient in each group underwent manipulation under anesthesia. No other readmissions, reoperations, or complications were reported. A novel durable medical equipment device can provide a safe and effective patient-controlled method for initial management of knee ROM, pain, and function after primary TKA with potential clinically meaningful advantages over physical therapy alone. In conjunction with physical therapy, management with this novel knee flexion device more effectively restored knee ROM and early patient function when compared with therapy alone and was associated with higher proportions of patients regaining minimum (115°) and desired (125°) levels of knee ROM and clinically meaningful differences in pain scores, knee function, and patient satisfaction. This is a Level 1, prospective trial study., Competing Interests: J.L.C., K.R., C.R.C., and T.M.G. are patent holders in the Mizzou BioJoint Flex device.

Female sex workers (FSW) are affected by individual, network, and structural risks, making them vulnerable to poor health and well-being. HIV prevention strategies and local community-based programs can rely on estimates of the number of FSW to plan and implement differentiated HIV prevention and treatment services. However, there are limited systematic assessments of the number of FSW in countries across sub-Saharan Africa to facilitate the identification of prevention and treatment gaps. Here we provide estimated population sizes of FSW and the corresponding uncertainties for almost all sub-national areas in sub-Saharan Africa. We first performed a literature review of FSW size estimates and then developed a Bayesian hierarchical model to synthesize these size estimates, resolving competing size estimates in the same area and producing estimates in areas without any data. We estimated that there are 2.5 million (95% uncertainty interval 1.9 to 3.1) FSW aged 15 to 49 in sub-Saharan Africa. This represents a proportion as percent of all women of childbearing age of 1.1% (95% uncertainty interval 0.8 to 1.3%). The analyses further revealed substantial differences between the proportions of FSW among adult females at the sub-national level and studied the relationship between these heterogeneities and many predictors. Ultimately, achieving the vision of no new HIV infections by 2030 necessitates dramatic improvements in our delivery of evidence-based services for sex workers across sub-Saharan Africa.

Objective: To assess the prevalence and predictors of underage initiation of selling sex among female sex workers (FSW) in Guinea-Bissau., Methods: 505 adult FSW recruited using respondent-driven sampling were surveyed in 2017. Multivariable logistic regression was used to identify demographic, behavioral, and psychosocial characteristics associated with initiation of selling sex while underage (<18 years)., Results: A total of 26.3% (133/505) of FSW started selling sex before age 18. Underage initiation of selling sex was associated with experiencing forced sex before age 18 (adjusted odds ratio (aOR): 6.74; 95% confidence interval (CI): 2.05-22.13), and never being tested for HIV (aOR: 0.43; 95% CI: 0.20-0.91). Despite having lower odds of wanting to have children or more children (aOR: 0.31; 95% CI: 0.17-0.56), FSW who started selling sex while underage had lower odds of using highly effective contraception such as implants (aOR: 0.43; 95% CI: 0.24-0.77). Among those who were ever pregnant, a lower percentage of FSW who started selling sex while underage accessed antenatal care (56.6% vs. 74.7%, p = 0.008)., Conclusions: These data suggest that early initiation of selling sex among adult FSW in Guinea-Bissau is common. Social services for youth and integrated HIV and reproductive health services are critical to address the persisting sexual and reproductive health needs of FSW who started selling sex while underage.

Background: Treatment of multisurface articular cartilage lesions of the knee is a challenging problem., Hypothesis: Large multisurface cartilage defects in the knee can be successfully managed with transplantation of high chondrocyte viability osteochondral allografts (OCAs) to result in statistically significant improvements in patient-reported outcome measures of pain and function., Study Design: Cohort study; Level of evidence, 3., Methods: Patients were prospectively enrolled into a registry to follow outcomes after OCA transplantation. The study included patients who received OCA transplantation for multisurface unipolar defects in 1 knee and had minimum 2-year follow-up data, including patient-reported outcome measures, failures, reoperations, and complications. The OCA transplants had been stored using 2 methods: standard preservation (SP) or Missouri Osteochondral Preservation System (MOPS). Preoperative data were compared with outcomes at 1 year and final follow-up, and risk factors for revision surgery or failure (total knee arthroplasty) were analyzed., Results: The sample included 25 patients with a mean age of 37.2 years (range, 13-51 years), body mass index of 27.7 (range, 18-38), and follow-up of 45.1 months (median, 49 months; range, 24-68 months). OCAs stored using SP were transplanted into 6 patients, and those stored using MOPS were transplanted into 19 patients. The initial success rate was significantly higher for MOPS OCAs (94.7%) than SP OCAs (33.3%). There were statistically significant improvements in all patient-reported outcomes at 1 year and final follow-up in the MOPS cohort ( P < .0001 for all). Revision surgery/failure was significantly associated with patients who were nonadherent to the prescribed postoperative restrictions and rehabilitation protocols ( P = .038; odds ratio = 13.5) and with OCAs that had a viable chondrocyte density <70% of the established reference range mean at transplantation ( P = .0037; odds ratio = 76)., Conclusion: OCA transplantation for treatment of large multisurface cartilage defects in the knee resulted in a 94.7% initial success rate when grafts with high viable chondrocyte density (≥70%) were used and when patients strictly adhered to prescribed postoperative rehabilitation protocols. Successful outcomes were associated with statistically significant improvements in patient-reported outcome measures of pain and function., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: J.L.C. has received research support from Arthrex, DePuy, GE Healthcare, Merial, Musculoskeletal Transplant Foundation, and Purina; consulting fees from Arthrex, Bioventus, and Trupanion; speaking fees from Arthrex; and royalties from Arthrex, Musculoskeletal Transplant Foundation, and Thieme.

Clinical outcomes after reconstruction for multiligamentous knee injury (MLKI) can be consistently favorable. However, recent implants and technique advances may allow for improvement in outcomes. Our institution has developed novel graft constructs and techniques for reconstructions with preclinical data supporting clinical use. Our study purpose was to assess clinical outcomes after reconstruction for MKLI using our constructs and techniques. Overall success rate, failure/revision rates, return to work (RTW)/return to sports (RTS) rates, and complications were evaluated testing the hypothesis that novel methods would be associated with clinical benefits with respect to applications and outcomes compared with historical results. We reviewed a single-surgeon, longitudinal database of 42 patients who underwent multiligament reconstruction at our institution using these techniques for at least two-ligament injuries. Visual analogue scale (VAS) pain score and PROMIS (patient-reported outcomes measurement information system) were collected preoperatively and postoperatively at a minimum 1-year follow-up. Among these patients, 33 patients (mean age of 28.9 years, mean body mass index (BMI) of 33.2 kg/m 2 , mean follow-up of 14.2 months) were included for outcomes analyses. With the definition of success as having a VAS score of less than or equal to 2 without revision/salvage surgery due to recurrent/residual instability or arthritis, overall success rate was 88% (29/33). The mean VAS scores improved from 5 ± 2 to 2 ± 2. The mean preoperative PROMIS mental health score was 36.2 ± 7, general health was 33.5 ± 6, pain was 62.7 ± 8, and physical function score was 29.4 ± 3. At the final follow-up, PROMIS MH was 50.2 ± 10, GH was 44.4 ± 9, pain was 54.3 ± 9, and PF was 42.6 ± 8.4. Return to work rate was 94% (31/33), and 52% (17/33) of patients were able to RTS at any level. Our results demonstrated excellent clinical outcomes associated with a primary success rate of 88% and RTW rate of 94%. Intraoperative complications occurred in 9.5% of cases and revision and failure rates were 9% and 3%, respectively. Our initial results suggest that multiligament reconstructions using novel graft constructs and techniques are safe and effective and can be considered an appropriate option for reconstruction of the full clinical spectrum of MLKIs., Competing Interests: J.P.S. reports grants and personal fees from Arthrex, Inc., grants from DePuy Synthes, other from Journal of Knee Surgery, grants from National Institutes of Health (NIAMS & NICHD), personal fees and other from Thieme, grants from U.S. Department of Defense, other from AO Foundation, other from American Orthopaedic Association, other from AO North America, grants from Coulter Foundation, other from Mid-America Orthopaedic Association, personal fees from Orthopaedic Designs North America, personal fees from Smith & Nephew, outside the submitted work.

Background: Surgical site infections (SSIs) significantly influence outcomes and health care costs after orthopaedic surgery, but they have not been well characterized for osteochondral allograft (OCA) transplantation with or without meniscal allograft transplantation (MAT)., Purpose: To characterize the incidence, cost, and risk factors associated with potential or confirmed SSIs after large single-surface, multisurface, or bipolar allograft transplantation in the knee., Study Design: Case-control study; Level of evidence, 3., Methods: Prospectively collected registry data were analyzed for patients who underwent primary or revision OCA transplantation with or without MAT in the knee. The Centers for Disease Control and Prevention (CDC) guidelines were used to define SSIs and calculate the SSI incidence. Both potential and confirmed SSIs were analyzed to determine related treatment methods, calculate associated health care costs, and characterize risk factors based on the OCA surgery type (single-surface, multisurface, bipolar, ±MAT), American Society of Anesthesiologists physical status classification system, surgery duration, length of stay, age, sex, body mass index (BMI), and current tobacco use., Results: A total of 224 patients were included in the analysis. There were 2 SSIs in 1 patient that met CDC criteria, such that the incidence for this patient population was 0.9%. An additional 7 patients (3.1%) were examined for potential infections not classified as SSIs. Patients with potential or confirmed SSIs had a significantly higher mean BMI compared to patients with no evidence of an SSI ( P <.001). BMI >35 (odds ratio, 9.1) and tobacco use (odds ratio, 6.6) were associated with greater odds for a potential or confirmed SSI. The mean health care costs were $6101 for patients who required additional emergency room visits and/or irrigation and debridement within 90 days postoperatively for potential or confirmed SSIs, $19 for patients with potential superficial incisional SSIs, and $12,100 for patients who experienced a potential or confirmed deep incisional or organ/space SSI >90 days from surgery., Conclusion: Large OCA transplantation with and without MAT were associated with a low incidence of confirmed SSIs (0.9%), and patients with BMI >35 and current tobacco use had greater odds of an SSI. Potential and confirmed SSIs were associated with unscheduled appointments, additional surgical procedures, and higher costs., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: J.P.S. has received research support from Arthrex; consulting fees from Arthrex, DePuy, Orthopedic Designs North America, and Smith & Nephew; and royalties from Thieme.

Background: Despite progress in improving antiretroviral therapy (ART) for people with HIV in Malawi, the burden of HIV infections and HIV treatment outcomes among key populations is suboptimal. Client-centered differentiated service delivery approaches may facilitate addressing HIV prevention and treatment needs of key populations in Malawi., Methods: De-identified program data routinely collected as part of the LINKAGES project-Malawi were assembled from October 2017 to September 2019. HIV case finding was compared across different testing modalities for each population. Poisson regression was used to estimate the association between testing modalities and ART initiation., Results: Of the 18   397 people included in analyses, 10   627 (58%) were female sex workers (FSWs), 2219 (12%) were men who have sex with men (MSM), and 4970 (27%) were clients of FSWs. HIV case finding varied by modality and population, with index testing and enhanced peer outreach demonstrating high yield despite reaching relatively few individuals. FSWs who tested positive through risk network referral testing were more likely to initiate ART within 30 days compared with those who tested positive through clinic-based testing (adjusted risk ratio [aRR], 1.50; 95% CI, 1.23-1.82). For MSM, index testing (aRR, 1.45; 95% CI, 1.06-2.00) and testing through a drop-in center (aRR, 1.82; 95% CI, 1.19-2.78) were associated with 30-day ART initiation., Conclusions: These data suggest that differentiated HIV testing and outreach approaches tailored to the needs of different key populations may facilitate improved ART initiation in Malawi. Achieving 0 new infections by 2030 suggests the need to adapt treatment strategies given individual and structural barriers to treatment for key populations with HIV in high-prevalence settings., (© The Author(s) 2022.

Objective: To better understand rectal STI screening practices for Black gay, bisexual and other men who have sex with men (BGBMSM)., Findings: Although 15% of BGBMSM lab tested positive for a rectal STI, the majority of these (94%) were asymptomatic. Though all participants reported their status as HIV negative/unknown, 31 of 331 (9.4%) tested positive on HIV rapid tests. Neither condomless anal intercourse nor the number of male sex partners was associated with rectal STI or HIV diagnosis, although rectal STI diagnosis was positively related to testing HIV positive., Conclusions: Findings suggest that substantial numbers of BGBMSM have asymptomatic STIs but are not tested-an outcome that is likely a strong driver of onward HIV acquisition. Therefore, we must address the asymptomatic STI epidemic among GBMSM in order to reduce HIV transmission, as well as temper STI transmission, among this key population., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Unicompartmental knee osteoarthritis (UKOA) is a complex issue that is estimated to affect roughly 28% of patients with knee OA, and can result in severe cartilage degeneration, meniscus deficiency, and concomitant varus or valgus malalignment. This malalignment results in abnormally high joint reaction forces in the affected compartment, which can elicit pain, cause dysfunction, and exacerbate joint degradation. For more than two decades, the use of knee unloader braces has been advocated as a cost-effective option for symptomatic management of UKOA.During bipedal ambulation with a normal lower extremity mechanical axis, ground reaction forces create a knee adduction moment (KAM) such that the medial compartment of the knee experiences approximately 60% of joint loading and the lateral compartment experiences approximately 40% of joint loading. UKOA disrupts the mechanical axis, altering KAM and joint loading and causing pain, dysfunction, and disease progression. In theory, knee unloader braces were designed to mitigate the symptoms of UKOA by normalizing KAM via shifts in the lever arms about the knee. However, studies vary, and suggest that push-mechanism knee unloaders do not consistently provide significant biomechanical benefits for medial or lateral UKOA. Current evidence suggests that pull-mechanism unloaders may be more effective, though contrasting data have also been reported, such that further validation is necessary. The purpose of our study was to synthesize current best evidence for use of knee unloader braces for management of UKOA to suggest evidence-based best practices as well as gaps in knowledge to target for future studies. Unloader bracing for patients with UKOA appears to be a cost-effective treatment option for patients with medial UKOA who have insurance coverage. Pull-mechanism unloader bracing should be considered in conjunction with other nonoperative management therapies for those who are willing to adhere to consistent brace use for weight-bearing activities., Competing Interests: None declared., (Thieme.

Background: Sampling frames rarely exist for key populations at highest risk for HIV, such as sex workers, men who have sex with men, people who use drugs, and transgender populations. Without reliable sampling frames, most data collection relies on non-probability sampling approaches including network-based methods (e.g. respondent driven sampling) and venue-based methods (e.g. time-location sampling). Quality of implementation and reporting of these studies is highly variable, making wide-ranging estimates often difficult to compare. Here, a modified quality assessment tool, Global.HIV Quality Assessment Tool for Data Generated through Non-Probability Sampling (GHQAT), was developed to evaluate the quality of HIV epidemiologic evidence generated using non-probability methods., Methods: The GHQAT assesses three main domains: study design, study implementation, and indicator-specific criteria(prevalence, incidence, HIV continuum of care, and population size estimates). The study design domain focuses primarily on the specification of the target and study populations. The study implementation domain is concerned with sampling implementation. Each indicator-specific section contains items relevant to that specific indicator. A random subset of 50 studies from a larger systematic review on epidemiologic data related to HIV and key populations was generated and reviewed using the GHQAT by two independent reviewers. Inter-rater reliability was assessed by calculating intraclass correlation coefficients for the scores assigned to study design, study implementation and each of the indicator-specific criteria. Agreement was categorized as poor(0.00-0.50), fair(0.51-0.70), and good(0.71-1.00). The distribution of good, fair, and poor scores for each section was described., Results: Overall, agreement between the two independent reviewers was good(ICC >0.7). Agreement was best for the section evaluating the HIV continuum of care(ICC = 0.96). For HIV incidence, perfect agreement was observed, but this is likely due to the small number of studies reviewed that assessed incidence(n = 3). Of the studies reviewed, 2% (n = 1) received a score of "poor" for study design, while 50% (n = 25) received a score of "poor" for study implementation., Conclusions: Addressing HIV prevention and treatment needs of key populations is increasingly understood to be central to HIV responses across HIV epidemic settings, though data characterizing specific needs remains highly variable with the least amount of information in the most stigmatizing settings. Here, we present an efficient tool to guide HIV prevention and treatment programs as well as epidemiological data collection by reliably synthesizing the quality of available non-probability based epidemiologic information for key populations. This tool may help shed light on how researchers may improve not only the implementation of, but also the reporting on their studies., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Background: The coronavirus pandemic has necessitated a range of population-based measures to stem the spread of infection. These measures may be associated with disruptions to other health services including for gay, bisexual, and other men who have sex with men (MSM) at risk for or living with HIV. Here, we assess the relationship between stringency of COVID-19 control measures and interruptions to HIV prevention and treatment services for MSM., Setting: Data for this study were collected between April 16, 2020, and May 24, 2020, as part of a COVID-19 Disparities Survey implemented by the gay social networking app, Hornet. Pandemic control measures were quantified using the Oxford Government Response Tracker Stringency Index: each country received a score (0-100) based on the number and strictness of 9 indicators related to restrictions, closures, and travel bans., Methods: We used a multilevel mixed-effects generalized linear model with Poisson distribution to assess the association between stringency of pandemic control measures and access to HIV services., Results: A total of 10,654 MSM across 20 countries were included. Thirty-eight percent (3992/10,396) reported perceived interruptions to in-person testing, 55% (5178/9335) interruptions to HIV self-testing, 56% (5171/9173) interruptions to pre-exposure prophylaxis, and 10% (990/9542) interruptions to condom access. For every 10-point increase in stringency, there was a 3% reduction in the prevalence of perceived access to in-person testing (aPR: 0·97, 95% CI: [0·96 to 0·98]), a 6% reduction in access to self-testing (aPR: 0·94, 95% CI: [0·93 to 0·95]), and a 5% reduction in access to pre-exposure prophylaxis (aPR: 0·95, 95% CI: [0·95 to 0·97]). Among those living with HIV, 20% (218/1105) were unable to access their provider; 65% (820/1254) reported being unable to refill their treatment prescription remotely., Conclusions: More stringent responses were associated with decreased perceived access to services. These results support the need for increasing emphasis on innovative strategies in HIV-related diagnostic, prevention, and treatment services to minimize service interruptions during this and potential future waves of COVID-19 for gay men and other MSM at risk for HIV acquisition and transmission., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: Sexual relationships among adolescent girls and young women (AGYW) are influenced by social, economic, and gender dynamics. Understanding AGYW's different relationship types and their implications for HIV risk is important for development of tailored interventions. We sought to identify relationship typologies among AGYW and their impact on uptake of HIV prevention interventions., Methods: From May 2018 to February 2019, 2200 HIV-negative AGYW (ages 16-24) in Johannesburg, South Africa, participated in an HIV prevention intervention involving distribution of HIV self-test kits to their male partners. AGYW were also offered pre-exposure prophylaxis. At baseline, AGYW completed a questionnaire, and outcomes were assessed for 3 months. We used latent class analysis to identify relationship types and mixture modeling to estimate the impact of relationship type on engagement in prevention interventions., Results: We identified 3 relationship types: "stable, empowered relationships with older partners" (class 1, n = 973); "shorter, empowered relationships with peer partners" (class 2, n = 1067); and "shorter relationships with risky partners" (class 3, n = 160). Compared with AGYW in class 1 relationships, AGYW in class 2 and 3 relationships were less likely to complete partner testing alongside HIV results sharing (class 2 adjusted risk ratio: 0.89, 95% confidence interval: 0.85 to 0.95; class 3 adjusted risk ratio: 0.84, 95% confidence interval: 0.73 to 0.94). Pre-exposure prophylaxis uptake was highest in class 3 (11.2%) compared with class 2 (3.8%) and class 1 (1.0%; P < 0.001)., Conclusions: Relationship type impacts uptake of HIV prevention interventions among South African youth. Intervention effectiveness could be optimized by using tailored approaches to HIV risk mitigation among AGYW., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2020 Wolters Kluwer Health, Inc.
