Glenohumeral chondrolysis is a rare and devastating complication of shoulder arthroscopy. The article presents three cases of rapid glenohumeral joint destruction following shoulder arthroscopy. These studies show that although thermal energy is suspected to play a role, the exact pathophysiology of the disease is not known. However, it is recommended avoiding the use of ablative thermal energy in the glenohumeral joint of young patients. Other relevant causal factors may include patient age, the use of bioabsorbable material within the joint, mechanical trauma to the joint surface from arthroscopic instruments or chemical trauma to the hyaline cartilage.

Background: Treatment of thromboembolism with intravenous heparin therapy in the early postoperative period after total joint arthroplasty has been associated with a high rate of complications. The purpose of the present study was to compare the rate of bleeding complications in a group of patients who required intravenous heparin therapy for the treatment of thromboembolism after total hip or knee arthroplasty with the rate in a control group of patients who received only prophylactic anticoagulation. Methods: The postoperative courses of forty-four consecutive patients who were managed with intravenous administration of heparin and oral administration of warfarin for the treatment of a thromboembolic event following unilateral total hip or knee arthroplasty were compared with those of a control group of 376 consecutive patients who had these same procedures but did not have a thromboembolic complication. The patients in the control group were managed with prophylactic anticoagulation with use of enoxaparin. Sixty-eight percent (thirty) of the forty-four patients in the heparin group received the initial dose of heparin on or before the fourth postoperative day, and 82 percent (thirty-six) received an initial bolus of 5000 units of heparin at the initiation of therapy. Results: The rate of bleeding complications was 9 percent (four of forty-four) in the heparin group, compared with 6 percent (twenty-three of 376) in the control group (p = 0.44). The mean transfusion requirement in the heparin group (1.8 units of packed red blood cells) was significantly greater than that in the control group (0.8 unit) (p < 0.0001). Three of the four patients who had a bleeding complication while receiving heparin and warfarin had coagulation parameters that were substantially higher than recommended levels. The mean duration of hospitalization in the heparin group (fifteen days) was significantly longer than that in the control group (seven days) (p < 0.0001). Conclusions:... [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to identify sex differences in postoperative outcomes and return‐to‐sport rates after fasciotomy for treatment of chronic exertional compartment syndrome (CECS) of the lower leg. It was hypothesised that male CECS patients would have a higher rate of return to sport than female CECS patients. Methods: A retrospective cohort study was conducted involving patients who underwent primary fasciotomy of one to four leg compartments for treatment of CECS at a single centre from 2010 to 2020. Each affected leg was treated as a separate subject. Postoperative outcomes included CECS pain frequency and severity, return to sport and Tegner activity level. Multivariable regression was used to determine if sex was an independent predictor of outcomes after adjusting for demographic and clinical covariates. p < 0.05 were considered significant. Results: Eighty‐one legs (44 M, 37 F) of 47 unique patients (34 of whom had bilateral symptoms) were included with a mean follow‐up time of 51.5 ± 31.4 months. Male subjects were older (p < 0.001) and had higher body mass index (p < 0.001) compared to female subjects. Most subjects (84.0%) underwent two‐ or four‐compartment fasciotomies. Female sex was found to be predictive of lower overall postoperative pain severity (p = 0.007), higher odds of return to sport (p = 0.04) and higher postoperative Tegner score (p = 0.005). However, female sex was not predictive of postoperative pain frequency, odds of reoperation or odds of return to sport to at least the presymptomatic level (all p < 0.05). Conclusion: Female sex is independently predictive of reduced overall pain severity, higher odds of return to sport and higher postoperative improvement in Tegner score following fasciotomy for treatment of lower‐limb CECS. Level of Evidence: III. [ABSTRACT FROM AUTHOR]

Background: Bone marrow stimulation (BMS) has been proposed to augment healing at the time of arthroscopic rotator cuff repair (ARCR) by creating several bone marrow vents in the footprint of the rotator cuff, allowing mesenchymal stem cells, platelets, and growth factors to cover the area as a "crimson duvet." Purpose: To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes after BMS and a control for those undergoing ARCR. Study Design: Meta-analysis; Level of evidence, 1. Methods: A literature search of 3 databases was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RCTs comparing BMS and a control for ARCR were included. Clinical outcomes were compared, and a P value <.05 was considered to be statistically significant. Results: A total of 7 RCTs with 576 patients were included. Overall, 18.8% of patients treated with BMS and 21.0% of patients treated with a control had a retear (I 2 = 43%; P =.61). With BMS, the mean Constant score was 88.2, and with the control, the mean Constant score was 86.7 (P =.12). Additionally, there was no significant difference in the American Shoulder and Elbow Surgeons score (94.3 vs 93.2, respectively; P =.31) or visual analog scale score (0.9 vs 0.9, respectively; P =.89). Conclusion: The level 1 evidence in the literature did not support BMS as a modality to improve retear rates or clinical outcomes after ARCR. [ABSTRACT FROM AUTHOR]

Background: The use of telerehabilitation after sports medicine procedures such as an arthroscopic rotator cuff repair (ARCR) and anterior cruciate ligament reconstruction (ACLR) has rapidly increased in recent years; however, the functional outcomes and patient satisfaction with telerehabilitation compared to in-person rehabilitation remain unclear. The purpose of this study was to compare the functional outcomes and patient satisfaction with telerehabilitation to in-person rehabilitation in a randomized controlled trial after two common sports procedures, ARCR and ACLR. Methods: Two randomized controlled trials were conducted involving patients scheduled to undergo ARCR or ACLR by one of six fellowship-trained sports medicine surgeons between October 2020 and November 2021. Each trial had an enrollment goal of 60 patients. Subjects were randomized 1:1 to receive telerehabilitation or in-person rehabilitation postoperatively. Functional outcome and satisfaction metrics were collected at baseline and at post-operative visits and compared between groups. Results: In total, 16 ACLR patients were enrolled, of whom 10 (62.5%) were assigned to in-person rehabilitation and 6 (37.5%) to telerehabilitation. Additionally, 32 ARCR patients were enrolled, of whom 20 (62.5%) were assigned in-person rehabilitation and 12 (37.5%) were assigned telerehabilitation. In total, of the 30 patients assigned to in-person rehabilitation, none reported a crossover to telerehabilitation. Of the 18 patients initially assigned to telerehabilitation, 12 (67%) completed the final follow-up survey, of which 11 (92%) reported a crossover; 9 patients completed in-person rehabilitation and 2 patients completed hybrid in-person and telerehabilitation. Conclusions: Patients preferred in-person rehabilitation compared to telerehabilitation after ACLR and ARCR, as evidenced by the nearly ubiquitous crossover from telerehabilitation to in-person rehabilitation in both studies. Our findings suggest that telerehabilitation protocols still need to be perfected, and that there may be a role for a hybrid in-person and tele-rehab model. [ABSTRACT FROM AUTHOR]

Purpose Methods Results Conclusion Level of Evidence The purpose of this study is to assess the association between sagittal tibial tuberosity‐trochlear groove (sTT‐TG) distance and patellofemoral chondral lesion size in patients undergoing cartilage restoration procedures.A retrospective cohort analysis of patients who underwent an osteochondral allograft transplantation or matrix‐induced autologous chondrocyte implantation in the patellofemoral compartment, from 2010 to 2020, were included if they had patellofemoral high‐grade lesions, magnetic resonance imaging (MRI) and minimum 2‐year follow‐up. The preoperative sTT‐TG distance was measured independently on axial T2‐weighted MRI sequences by two authors, each at least two weeks apart. Intraoperative lesion size was reported according to operative report measurements by the attending surgeon. An interclass correlation coefficient (ICC) was calculated to assess intra‐ and inter‐rater reliability, and categorical data analysis and linear regression models were used to assess the relationship between sTT‐TG and lesion size.A total of 80 patients (50 females) with a mean age of 31.5 ± 10.4 years, body mass index of 27.0 ± 5.9 kg/m2 and follow‐up of 61.5 ± 21.4 months were included. A total of 107 lesions were present: 63 patients with unipolar (patella = 41, trochlea = 22) and 22 with bipolar lesions. The mean MRI defect size was 1.6 ± 1.0 cm2 and the mean intraoperative defect size was 3.8 ± 2.4cm2. Intra‐ (ICC: 0.99,0.98) and inter‐rater reliability (ICC: 0.96) were excellent for both MRI defect size and sTT‐TG measurements. The mean sTT‐TG was −4.8 ± 4.9 mm and was significantly inversely related to MRI defect size (−0.45, p < 0.01), intraoperative patellar lesion size (−0.32, p = 0.01), total lesion area (−0.22, p = 0.04), but not trochlear lesion size (−0.09, p = 0.56). Multivariable regression demonstrated a more negative sTT‐TG remained an independent variable correlated with larger MRI‐measured patellofemoral defect sizes and intraoperative patellar lesions.A more negative sTT‐TG was an independent variable correlated with larger patellofemoral lesions in patients undergoing patellofemoral cartilage restoration.Level III, Diagnostic.

Background: Open subpectoral biceps tenodesis (OSBT) with cortical button fixation has been shown to deliver acceptable results in the short and intermediate term for long head of the biceps (LHB) pathology with the benefit of smaller bone tunnel diameter and a reduced risk of postoperative humeral shaft fracture. The primary purpose of this study was to determine whether OSBT with cortical button fixation results in significant improvements in patient reported outcomes (PROs) from pre-operative to long-term final follow-up. Methods: A retrospective analysis of patients who underwent OSBT with cortical button fixation at a single institution between the years of 2012 and 2014 was conducted and PROs were collected in the intermediate (> 2 years follow-up) and long term (> 9 years follow-up). PROs were measured pre-operatively, at intermediate follow-up, and at long-term follow-up using three validated questionnaires: American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and Oxford Shoulder Score (OSS). Patients were additionally asked at final follow-up if they would undergo the same procedure again if they needed it. Results: Twenty-nine (29) patients with a mean age of 51.16 ± 9.06 years at the time of surgery were included in the study at final follow-up. Mean final follow-up time was 10.2 ± 0.5 years (range: 9.2–11.1 years). All PROs (ASES, OSS, and DASH) demonstrated statistically significant improvements from pre-operative to final follow-up with p < 0.01 for each. The proportions of patients exceeding established values for minimum clinically important difference (MCID) were 96.55%, 93.10%, and 75.86% for ASES, OSS, and DASH respectively. Only one patient had required re-operation as of final follow-up. None experienced humeral fractures post-operatively. A significant majority (89.66%; p < 0.01) of patients reported that they would undergo the same procedure again if they needed it. Fifty-three (53) patients were included in the study at intermediate follow-up with a mean follow-up time of 3.5 ± 1.4 years (range: 2–5.3 years). There were no statistically significant differences in any of the PRO measures from intermediate to long-term follow-up. Conclusion: This study reported a minimum 9-year follow-up of patients undergoing OSBT with cortical button fixation for the management of LHBT pathology in the setting of concomitant shoulder procedures. All patients had significantly improved functional outcomes assessed with ASES, OSS, and DASH and no obvious differences in median group scores were found between patients assessed at intermediate (mean 3.5 years) and final (mean 10.2 years) follow-up. No infections, fractures, or fixation failures were reported. [ABSTRACT FROM AUTHOR]

Background: Previous research has found that the incidence of neurovascular injury is greatest among multiligamentous knee injuries (MLKIs) with documented knee dislocation (KD). However, it is unknown whether there is a comparative difference in functional recovery based on evidence of a true dislocation. Purpose: To determine whether the knee dislocation-3 (KD3) injury pattern of MLKI with documented tibiofemoral dislocation represents a more severe injury than KD3 MLKI without documented dislocation, as manifested by poorer clinical outcomes at long-term follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: A multicenter retrospective cohort study was performed of patients who underwent surgical treatment for KD3 MLKI between May 2012 and February 2021. Outcomes were assessed using the International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner activity scale, and visual analog scale (VAS) for pain. Documented dislocation was defined as a radiographically confirmed tibiofemoral disarticulation, the equivalent radiology report from outside transfer, or emergency department documentation of a knee reduction maneuver. Subgroup analysis was performed comparing lateral (KD3-L) versus medial (KD3-M) injuries. Multivariable linear regression was conducted to determine whether documented dislocation was predictive of outcomes. Results: A total of 42 patients (25 male, 17 female) were assessed at a mean 6.5-year follow-up (range, 2.1-10.7 years). Twenty patients (47.6%) were found to have a documented KD; they reported significantly lower IKDC (49.9 vs 63.0; P =.043), Lysholm (59.8 vs 74.5; P =.023), and Tegner activity level (2.9 vs 4.7; P =.027) scores than the patients without documented dislocation. VAS pain was not significantly different between groups (36.4 vs 33.5; P =.269). The incidence of neurovascular injury was greater among those with documented dislocation (45.0% vs 13.6%; P =.040). Subgroup analysis found that patients with KD3-L injuries experienced a greater deficit in Tegner activity level than patients with KD3-M injuries (Δ: –3.4 vs −1.2; P =.006) and had an increased incidence of neurovascular injury (41.7% vs 11.1%; P =.042). Documented dislocation status was predictive of poorer IKDC (β = −2.15; P =.038) and Lysholm (β = −2.85; P =.007) scores. Conclusion: Patients undergoing surgical management of KD3 injuries with true, documented KD had significantly worse clinical and functional outcomes than those with nondislocated joints at a mean 6.5-year follow-up. The current MLKI classification based solely on ligament involvement may be obscuring outcome research by not accounting for true dislocation. [ABSTRACT FROM AUTHOR]

Background: Medial patellofemoral ligament (MPFL) reconstruction is being performed more frequently in athletes experiencing recurrent patellar instability. Purpose/Hypothesis: The purpose was to systematically review the evidence in the orthopaedic sports medicine literature to determine both the rate and timing of return to play after MPFL reconstruction and the rate of further patellar instability. Our hypothesis was that there would be a high rate of return to play after MPFL reconstruction. Study Design: Systematic review. Methods: A systematic literature search was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, which utilized EMBASE, MEDLINE, and the Cochrane Library databases. Inclusion criteria for literature included clinical studies reporting on return to play after MPFL reconstruction. Rate of return to play, level of return, timing of return, rate of recurrent instability, and patient-reported outcomes were evaluated. Statistical analysis was performed using SPSS. Results: Our review found 27 studies including 1278 patients meeting our inclusion criteria. The majority of patients were women (58%), and the total group had a mean age of 22.0 years and a mean follow-up of 39.3 months. The overall rate of return to play was 85.1%, with 68.3% returning to the same level of play. The average time to return to play was 7.0 months postoperatively. The rate of recurrent instability events following reconstruction was 5.4%. There was an improvement in both mean visual analog scale, pain scores (preoperative: 4.3, postoperative: 1.6) and Tegner activity scores (preoperative: 4.8, postoperative: 5.5). Conclusion: The overall rate of return to play was high after MPFL reconstruction for the treatment of recurrent patellar instability. However, a relatively high percentage of those patients were unable to return to their preoperative level of sport. Additionally, there was a moderate time taken to return to play, at approximately 7 months after the procedure. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the rate of return to sports and sport psychological readiness between patients who underwent isolated MPFLR (iMPFLR) compared to a matched cohort of patients who underwent MPFLR with anteromedializing tibial tubercle osteotomy (MPFLR/TTO). Methods: Patients who underwent primary MPFLR with or without TTO for recurrent patellar instability were retrospectively reviewed from 2012 to 2020 at a single institution. Preinjury sport and work information, Kujala, Tegner, Visual Analogue Score for pain, satisfaction and MPFL‐Return to Sport after Injury (MPFL‐RSI) score were collected. Two readers independently measured the tibial tuberosity‐trochlear groove distance, Caton–Deschamps index and Dejour classification for trochlear dysplasia. Patients in iMPFLR and MPFLR/TTO groups were matched 1:1 on age, sex, body mass index and follow‐up length. Multivariate regression analysis was performed to determine whether the MPFL‐RSI was associated with a return to sport. Results: This study included 74 patients at mean follow‐up of 52.5 months (range: 24–117). These groups returned to sport at similar rates (iMPFLR: 67.6%, MPFLR/TTO: 73.0%, not significant [ns]), though iMPFLR patients returned more quickly (8.4 vs. 12.8 months, p = 0.019). Rates of return to preinjury sport level were also similar (45.9% vs. 40.5%, ns). Patients with Dejour B/C took more time to return to sport compared to patients with mild/no trochlear pathology (13.8 vs. 7.9 months, p = 0.003). Increasing MPFL‐RSI score was significantly predictive of the overall return to sport (odds ratio [OR]: 1.08, 95% confidence interval [CI] [1.03, 1.13], p < 0.001) and return to preinjury level (OR: 1.07, 95% CI [1.04, 1.13], p < 0.001). Most patients in iMPFLR and MPFLR/TTO groups resumed work (95.7% vs. 88.5%, ns), though iMPFLR patients who returned to preinjury work levels did so more quickly (1.7 vs. 4.6 months, p = 0.005). Conclusion: Patients who underwent MPFLR with anteromedializing TTO demonstrated similar rates of return to sport and psychological readiness compared to an isolated MPFLR matched comparison group, though iMPFLRs returned more quickly. Patients with more severe trochlear pathology required more time to return to sports. Level of Evidence: Level III. [ABSTRACT FROM AUTHOR]

Purpose: Arthroscopic Bankart repair (ABR) may be more effective than nonoperative management for patients with anterior shoulder instability following first-time dislocation. The purpose of the study was to determine the most cost-effective treatment strategy by evaluating the incremental cost-effectiveness ratio (ICER) for ABR versus nonoperative treatment. Methods: This cost-effectiveness study utilized a Markov decision chain and Monte Carlo simulation. Probabilities, health utility values, and outcome data regarding ABR and nonoperative management of first-time shoulder instability derived from level I/II evidence. Costs were tabulated from Centers for Medicaid & Medicare Services. Probabilistic sensitivity analysis was performed using >100,000 repetitions of the Monte Carlo simulation. A willingness-to-pay (WTP) threshold was set at $50,000. Results: The expected cost for operative management higher than nonoperative management ($32,765 vs $29,343). However, ABR (5.48 quality-adjusted life years (QALYs)) was the more effective treatment strategy compared to nonoperative management (4.61 QALYs). The ICER for ABR was $3943. Probabilistic sensitivity analysis showed that ABR was the most cost-effective strategy in 100% of simulations. Discussion: ABR is more cost-effective than nonoperative management for first-time anterior shoulder dislocation. The threshold analysis demonstrated that when accounting for WTP, ABR was found to be the more cost-effective strategy. [ABSTRACT FROM AUTHOR]

Background:The purpose of this study was to determine if any differences exist in patient satisfaction with office-based visits versus telemedicine visits following arthroscopic shoulder surgery. Methods:Patients undergoing shoulder arthroscopy were prospectively enrolled for 1 year. Patient demographic and clinical data (including complication events) and second postoperative visit satisfaction data were recorded and analyzed for statistical significance. Results:Ninety-six (n = 96) patients met inclusion criteria. Fifty-four patients (56.3%) participated in a traditional in-person office visit, and 42 participated in a video visit (43.8%). No significant differences were found between office and video appointments in terms of overall care satisfaction (9.46 ± 0.9 vs. 9.55 ± 1.0, p = 0.67). Females were significantly less satisfied with their second postoperative visit compared with males (8.3 ± 2.3 vs. 9.3 ± 1.5, p = 0.035). Significantly more females would also have preferred a traditional in person office visit compared with males (91% vs. 67%, p = 0.009). Video appointment patients spent significantly more time with their surgeon than office visit patients (57.64 mean rank vs. 41.39 mean rank, p = 0.003). Discussion:Video visit patients required significantly less time overall for their visit and spent significantly more time with their surgeon, although did not demonstrate differences in satisfaction.

Purpose: Lateral patellar instability is a debilitating condition not only to athletes, but also to a wide range of highly active individuals. Many of these patients experience symptoms bilaterally, though it is unknown how these patients fair with return to sports following a second medial patellofemoral ligament reconstruction (MPFLR). The purpose of this study is to evaluate the rate of return to sport following bilateral MPFLR compared to a unilateral comparison group. Methods: Patients who underwent primary MPFLR with minimum 2-year follow-up were identified from 2014 to 2020 at an academic center. Those who underwent primary MPFLR of bilateral knees were identified. Pre-injury sport participation and Tegner score, Kujala score, Visual Analog Score (VAS) for pain, satisfaction, and MPFL-Return to Sport after Injury (MPFL-RSI) scale were collected. Bilateral and unilateral MPFLRs were matched in a 1:2 ratio based on age, sex, body mass index, and concomitant tibial tubercle osteotomy (TTO). A sub-analysis was performed regarding concomitant TTO. Results: The final cohort consisted of 63 patients, including 21 patients who underwent bilateral MPFLR, matched to 42 unilateral patients at mean follow-up of 47 ± 27 months. Patients who underwent bilateral MPFLR returned to sport at a rate of 62% at a mean of 6.0 ± 2.3 months, compared to a unilateral rate of 72% at 8.1 ± 4.2 months (n.s.). The rate of return to pre-injury level was 43% among bilateral patients and 38% in the unilateral cohort. There were no significant differences in VAS pain, Kujala, current Tegner, satisfaction, and MPFL-RSI scores between cohorts. Approximately half of those (47%) who failed to return to sport cited psychological factors and had significantly lower MPFL-RSI scores (36.6 vs 74.2, p = 0.001). Conclusion: Patients who underwent bilateral MPFLR returned to sports at a similar rate and level compared to a unilateral comparison group. MPFL-RSI was found to be significantly associated with return to sport. Level of evidence: III. [ABSTRACT FROM AUTHOR]

Background: An increased posterior tibial slope (PTS) is a risk factor for primary anterior cruciate ligament (ACL) tears and graft failure, but the PTS has not been well-defined in those who have experienced bilateral ACL injuries. Purpose: The primary aim was to compare the PTS, as well as the rate of an elevated PTS (>12° on lateral radiography; >7° on magnetic resonance imaging [MRI]), between patients who have undergone bilateral ACL reconstruction (ACLR) versus unilateral ACLR. A secondary purpose was to examine whether these associations remained consistent on both plain radiography and MRI. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We retrospectively identified patients who underwent primary ACLR at our institution from the years 2012 to 2020. Patients who underwent nonsimultaneous bilateral ACLR (n = 53) were matched to those who underwent unilateral ACLR (n = 53) by age, sex, and body mass index. Exclusion criteria were rotated lateral radiographs, MRI scans of inadequate quality, and concomitant ligament injuries or fractures. Those who had undergone unilateral ACLR with <5-year follow-up were further excluded. There were 3 blinded readers who measured the PTS on lateral radiographs, while the medial PTS (MPTS) and lateral PTS (LPTS) were measured on MRI scans. Bivariate regression was performed to determine the correlation between radiographic and MRI measurements. Results: The PTS on radiography (11.26° vs 10.13°, respectively; P =.044) and the LPTS on MRI (7.32° vs 6.08°, respectively; P =.012) in the bilateral ACLR group were significantly greater than those in the unilateral ACLR group but not the MPTS on MRI (4.55° vs 4.17°, respectively; P =.590). The percentage of patients in the bilateral group with a radiographic PTS >12° was 41.0% compared with 13.2% in the unilateral group (P =.012). The bilateral group had a significantly higher rate of an LPTS >7° compared with the unilateral group (53.8% vs 32.1%, respectively; P =.016) but not for an MPTS >7° (P =.190). On MRI, the LPTS (6.90°± 2.73°) was significantly greater than the MPTS (4.41°± 2.92°) (P <.001). There was a weak correlation between MPTS and radiographic PTS measurements (R = 0.24; P =.021), but LPTS and radiographic PTS measurements were not significantly correlated (R = 0.03; P =.810). Conclusion: Patients who underwent bilateral ACLR had a significantly greater PTS on radiography and a significantly greater LPTS on MRI compared with those who underwent unilateral ACLR. The rate of a radiographic PTS >12° was 2.4 times greater among patients undergoing bilateral ACLR compared with those undergoing unilateral ACLR. PTS measurements on radiography demonstrated a weak to negligible correlation with PTS measurements on MRI, suggesting that future normative PTS values should be reported specific to the imaging modality.

Objective: To determine whether concomitant psychiatric diagnoses and medication use were associated with postfasciotomy outcomes in patients with chronic exertional compartment syndrome (CECS). Design: Retrospective comparative cohort study. Setting: Single academic medical center from 2010 to 2020. Patients: All patients above 18 years old who underwent fasciotomy for CECS. Assessment of Risk Factors/Independent Variables: Psychiatric history was recorded from electronic health records including disease diagnosis and medications. Main Outcome Measures: The 3 main outcome measures were postoperative pain using the Visual Analog Scale, functional outcomes using the Tegner Activity Scale, and return to sport. Results: Eighty one subjects (legs), 54% male, with an average age of 30 years and follow-up of 52 months were included. 24 subjects (30%) had at least one psychiatric diagnosis at the time of surgery. Regression analysis found psychiatric history to be an independent predictor of worse postoperative pain severity and postoperative Tegner scores (P < 0.05). Furthermore, subjects with psychiatric disorders not on medication had worse pain severity (P < 0.001) and Tegner scores (P < 0.01) versus controls, whereas subjects with a psychiatric disorder on medication had better pain severity (P < 0.05) versus controls. Conclusions: History of psychiatric disorder was predictive of worse postoperative pain and activity outcomes after fasciotomy for CECS. Use of psychiatric medication was associated with improvement in pain severity in some domains. [ABSTRACT FROM AUTHOR]

Purpose: The indications for surgical treatment of proximal hamstring ruptures are continuing to be refined. The purpose of this study was to compare patient-reported outcomes (PROs) between patients who underwent operative or nonoperative management of proximal hamstring ruptures. Methods: A retrospective review of the electronic medical record identified all patients who were treated for a proximal hamstring rupture at our institution from 2013 to 2020. Patients were stratified into two groups, nonoperative or operative management, which were matched in a 2:1 ratio based on demographics (age, gender, and body mass index), chronicity of the injury, tendon retraction, and number of tendons torn. All patients completed a series of PROs including the Perth Hamstring Assessment Tool (PHAT), Visual Analogue Scale for pain (VAS), and the Tegner Activity Scale. Statistical analysis was performed using multi-variable linear regression and Mann–Whitney testing to compare nonparametric groups. Results: Fifty-four patients (mean age = 49.6 ± 12.9 years; median: 49.1; range: 19–73) with proximal hamstring ruptures treated nonoperatively were successfully matched 2:1 to 27 patients who had underwent primary surgical repair. There were no differences in PROs between the nonoperative and operative cohorts (n.s.). Chronicity of the injury and older age correlated with significantly worse PROs across the entire cohort (p < 0.05). Conclusions: In this cohort of primarily middle-aged patients with proximal hamstring ruptures with less than three centimeters of tendon retraction, there was no difference in patient-reported outcome scores between matched cohorts of operatively and nonoperatively managed injuries. Level of evidence: Level III. [ABSTRACT FROM AUTHOR]

Purpose: Acute Achilles tendon ruptures (AATRs) are a common sporting injury, whether for recreational athletes or elite athletes. Prior research has shown returning to physical activity after extended periods of inactivity leads to increased rates of musculoskeletal injuries. The purpose of this study was to investigate rates of acute Achilles' tendon ruptures at a single academic institute in the peri-COVID era, with corollary to the recent NFL season. Methods: A retrospective search was conducted using current procedural terminology to identify the total number of Achilles acute primary repair surgeries performed from years 2017 to 2021. Non-operatively managed AATRs were identified from the same electronic medical record using ICD-10 codes. NFL data were obtained from publicly available sites according to previously validated studies. Results: A total of 588 patients who sustained AATRs and underwent primary surgical repair were identified, primarily men (75.7%, n = 445), with an average age of 43.22 ± 14.4 years. The number and corresponding incidence of AATR repairs per year was: 2017: n = 124 (21.1%), 2018: n = 110 (18.7%), 2019: n = 130 (22.1%), 2020: n = 86 (14.6%), 2021: n = 138 (23.5%), indicating a 7.5% decrease in rate of AATRs from 2019 to 2020, followed by an 8.9% increase in incidence from 2020 to 2021. Within the NFL, the number of AATRs resulting in an injured reserve stint increased every regular season from 2019 to 2020: n = 11 (21.2%), to 2020–2021: n = 17 (32.7%), to this past 2021–2022 season: n = 24 (46.2%). Conclusion: AATR surgeries seem to have increased in 2021 following a 2020 COVID pandemic-induced quarantine for recreational athletes at a single academic institution and for professional athletes in the NFL, although these results are of questionable clinical significance. This provides prognostic information when counseling patients and athletes on return to activity or sport. Level of evidence: Level IV. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to identify predictors of the time from initial presentation to total shoulder arthroplasty (TSA) in patients with primary glenohumeral osteoarthritis (OA) and rotator cuff (RTC) arthropathy who were conservatively managed with corticosteroid injections. Methods: We conducted a retrospective cohort study of patients who underwent TSA from 2010 to 2021. Kaplan-Meier survival analysis was used to estimate median time to TSA for primary OA and RTC arthropathy patients. The Cox proportional hazards model was used to identify significant predictors of time to TSA and to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Statistical significance was set at P<0.05. Results: The cohort included 160 patients with primary OA and 92 with RTC arthropathy. In the primary OA group, median time to TSA was 15 months. Significant predictors of shorter time to TSA were older age at presentation (HR, 1.02; 95% CI, 1.00-1.04; P=0.03) and presence of moderate or severe acromioclavicular joint arthritis (HR, 1.45; 95% CI, 1.05-2.01; P=0.03). In the RTC arthropathy group, median time to TSA was 14 months, and increased number of corticosteroid injections was associated with longer time to TSA (HR, 0.87; 95% CI, 0.80-0.95; P=0.003). Conclusions: There are distinct prognostic factors for progression to TSA between primary OA patients and RTC arthropathy patients managed with corticosteroid injections. Multiple corticosteroid injections are associated with delayed time to TSA in RTC arthropathy patients. [ABSTRACT FROM AUTHOR]

Introduction: Prior studies of hamstring tendon tears have reported varied findings on whether increased delay from injury to surgery is associated with worse outcomes. The purpose of this study was to determine whether increased time from injury to surgical repair is associated with worse clinical outcomes in patients with proximal hamstring ruptures. Materials and methods: Patients who underwent surgical repair of a proximal hamstring rupture from 2010 to 2019 were followed for a minimum of 24 months from surgery. A cutoff of 6 weeks from injury to the time of surgery was used to distinguish between acute and chronic ruptures. All patients completed patient-reported outcome measures (PROs) at the final follow-up. Multiple factors were analyzed for their effects on PROs including time to surgery, amount of tendon retraction, and demographics such as sex and age. Results: Complete data sets were obtained for 38 patients at a mean follow-up of 4.9 years. All data is reported as a mean ± standard deviation. Patients who underwent acute repair of proximal hamstring ruptures had significantly greater Perth Hamstring Assessment Tool (PHAT) scores than those who underwent chronic repair (76.9 ± 18.8 vs 60.6 ± 18.2, p = 0.01). Increased time to surgery was significantly correlated with worse PHAT scores (ρ = − 0.47, p = 0.003). There was no difference in PROs based on the amount of tendon retraction, number of tendons torn, sex, smoking status, or BMI. Conclusions: This study found that acute repair performed within 6 weeks of injury appears to yield improved PROs compared to chronic repair. These data highlight the importance of timely and accurate diagnosis of proximal hamstring ruptures and early operative intervention for surgical candidates. [ABSTRACT FROM AUTHOR]

Background: The minimal clinically important difference (MCID) is a term synonymous with orthopaedic clinical research over the past decade. The term represents the smallest change in a patient-reported outcome measure that is of genuine clinical value to patients. It has been derived in a myriad of ways in existing orthopaedic literature. Purpose: To describe the various modalities for deriving the MCID. Study Design: Narrative review; Level of evidence, 4. Methods: The definitions of common MCID determinations were first identified. These were then evaluated by their clinical and statistical merits and limitations. Results: There are 3 primary ways for determining the MCID: anchor-based analysis, distribution-based analysis, and sensitivity- and specificity-based analysis. Each has unique strengths and weaknesses with respect to its ability to evaluate the patient's clinical status change from baseline to posttreatment. Anchor-based analyses are inherently tied to clinical status yet lack standardization. Distribution-based analyses are the opposite, with strong foundations in statistics, yet they fail to adequately address the clinical status change. Sensitivity and specificity analyses offer a compromise of the other methodologies but still rely on a somewhat arbitrarily defined global transition question. Conclusion: This current concepts review demonstrates the need for (1) better standardization in the establishment of MCIDs for orthopaedic patient-reported outcome measures and (2) better study design—namely, until a universally accepted MCID derivation exists, studies attempting to derive the MCID should utilize the anchor-based within-cohort design based on Food and Drug Administration recommendations. Ideally, large studies reporting the MCID as an outcome will also derive the value for their populations. It is important to consider that there may be reasonable replacements for current derivations of the MCID. As such, future research should consider an alternative threshold score with a more universal method of derivation. [ABSTRACT FROM AUTHOR]

Background Single-stage medial meniscus allograft transplantation (MAT) with concomitant anterior cruciate liga‑ ment reconstruction (ACLR) is a technically challenging procedure for management of knee pain and instability in younger patients, but clinical and functional outcomes data are sparse. The purpose of this study was to assess surgi‑ cal and patient-reported outcomes following concomitant ACLR and medial MAT. Methods We conducted a retrospective case series of patients who underwent medial MAT with concomitant primary or revision ACLR at our institution from 2010 to 2021 and had minimum 12-month follow-up. Complications, reoperations, visual analog scale (VAS) pain, satisfaction, Lysholm score, return to sport, and return to work outcomes were assessed. Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference, Pain Intensity, and Physical Function Scores were used to measure patients’ functional status relative to the US population. P-values<0.05 were considered signifcant. Results The cohort consisted of 17 knees of 16 individual patients. The cohort was majority male (82.4%) with mean age of 31.9 years (range 19–49 years) and mean body mass index (BMI) of 27.9 kg/m² (range 22.5–53.3 kg/m2 ). Mean follow-up time was 56.8 months (range 13–106 months). Most patients underwent revision ACLR (64.7%). The 1-year reoperation rate was high (23.5%), with two patients (11.8%) tearing their meniscus graft. Patient-reported outcomes indicated low VAS pain (mean 2.2), high satisfaction (mean 77.9%), and fair Lysholm score (mean 81.1). Return to work rate was high (92.9%), while return to sport rate was low (42.9%). Postoperative PROMIS scores were comparable or superior to the national average and correlated signifcantly with patient satisfaction (p<0.05). Conclusions The concomitant ACLR and MAT procedure is associated with excellent knee pain and functional out‑ comes and high rate of return to work after surgery, though the 1-year reoperation rate is high and rate of return to sport is low. Level of evidence: IV. [ABSTRACT FROM AUTHOR]

Purpose: Multi-ligamentous knee injuries (MLKIs) are high-energy injuries that may infrequently present with concomitant patellar tendon rupture. There is limited information in the literature regarding these rare presentations, with even less information regarding clinical outcomes. Using propensity-score matching, the purpose of this study was to compare the outcomes of MLKIs with and without patellar tendon ruptures and to investigate the overall predictors of these outcomes. Methods: Twelve patients who underwent surgical repair for combined MLKI and patellar tendon rupture from 2011 to 2020 with minimum 1-year follow-up data were identified from two separate institutions. Patients were propensity-score matched with a 1:1 ratio with controls based on age, body mass index (BMI), gender, and time from surgery. Patient-reported outcomes included International Knee Documentation Committee (IKDC) Subjective Knee Form, Lysholm and Tegner scores. Results: Twelve MLKIs with concomitant patellar tendon injuries were identified out of a multicenter cohort of 237 (5%) patients sustaining MLKI and were case matched 1:1 with 12 MLKIs without extensor mechanism injuries. The average follow-up was 5.5 ± 2.6 years. There were no differences in Schenck Classification injury patterns. There were significant differences found across IKDC (Patellar Tendon mean: 53.1 ± 24.3, MLKI mean 79.3 ± 19.6, P < 0.001) and Lysholm scores (Patellar Tendon mean: 63.6 ± 22.3, MLKI mean 86.3 ± 10.7, P < 0.001) between the two, illustrating poorer outcomes for patients with concomitant patellar tendon ruptures. Conclusion: In the setting of MLKI, patients who have a concomitant patellar tendon rupture have worse functional outcomes compared to those without. This information will be important for patient counseling and might be considered to be added to Schenck classification, reflecting its prognostic value. Level of evidence: Level IV.

Background: Recent interest has surged in the anterolateral ligament (ALL) and complex (ALC) of the knee. Its existence and role in rotary stability of the knee, particularly in the setting of anterior cruciate ligament (ACL) reconstruction, remains a contentious and controversial topic. Understanding the ALC: We must review our history and recognize the pioneers who pushed our understanding of the ALL forward before it was popularly recognized as a discrete structure. Additionally, given that many eponyms remain in common use related to the ALC, we must standardize our nomenclature to prevent misuse or misunderstanding of terms in the literature. In this review, modern understanding of the anterolateral ligament complex (ALC) is traced to 1829 by exploring eponymous terms first in anatomy and then in surgical technique. Understanding our history and terminology will allow us to better understand the ALC itself. Conclusion: This review aims to provide historical context, define terminology, and provide insight into the clinical relevance of the ALC. [ABSTRACT FROM AUTHOR]

Background: Patients undergoing anterior cruciate ligament (ACL) reconstruction have been shown to be at risk for postoperative arthrofibrosis. Diagnostic biomarkers associated with the development of postoperative stiffness are unknown. Hypothesis: Biomarkers found in the synovial fluid at the time of surgery are associated with the development of postoperative arthrofibrosis in a cohort of patients undergoing ACL reconstruction. Study Design: Case-control study; Level of evidence, 3. Methods: Patients undergoing ACL reconstruction were prospectively enrolled. Synovial fluid was collected before surgical incision. A cohort of patients with postoperative stiffness requiring manipulation under anesthesia (MUA) and/or lysis of adhesions (LOA) was retrospectively identified. Matching of cases to controls was performed using a 1:2 pair matching algorithm. Risk factor–adjusted single-biomarker and multivariable models were used to assess the association of synovial fluid biomarkers with postoperative stiffness requiring MUA/LOA. Stepwise logistic regression controlling for clinical risk factors was used to identify biomarkers that are possible predictors of postoperative stiffness. Results: A total of 11 cases (3 male, 8 female) were identified and matched with 21 controls (6 male, 15 female) with no significant differences in age, sex, smoking history, or days from injury to surgery. Concentrations of the biomarker regulated upon activation, normal T-cell expressed and presumably secreted (RANTES) were significantly higher in patients requiring MUA/LOA versus controls (694.20 pg/mL [interquartile range, 214.75-3428.79] vs 113.04 pg/mL [interquartile range, 32.81-517.91], respectively; P =.034). On single-biomarker models, RANTES (odds ratio, 2.28; 95% CI, 1.29-5.37; P =.019) and basic fibroblast growth factor (bFGF) (odds ratio, 1.91; 95% CI, 1.07-3.99; P =.047) were associated with increased risk of postoperative stiffness requiring MUA/LOA after ACL reconstruction. Stepwise logistic regression identified 3 biomarkers that are possible predictors of postoperative stiffness, which were included in the final model: Interleukin 1 receptor antagonist (IL-1RA) (P =.198), bFGF (P =.157), and RANTES (P =.046). Conclusion: Higher concentrations of synovial fluid biomarkers bFGF and RANTES were associated with increased risk for stiffness requiring intervention after ACL reconstruction. Interleukin 6 (IL-6), vascular endothelial growth factor A (VEGF-A), tissue inhibitor of metalloproteinases 1 (TIMP-1), interleukin 1 receptor antagonist (IL-1RA), matrix metalloproteinase 3 (MMP-3), monocyte chemotactic protein 1 (MCP-1), and macrophage inflammatory protein 1B (MIP-1B) were not associated with the development of postoperative arthrofibrosis.

Introduction: Telemedicine is a relatively new adjunct in orthopedic care but it has emerged from the periphery, driven in part by the COVID-19 pandemic. Although it has drastically increased in use, little is known of the factors that drive satisfaction with telemedicine. The purpose of the current study was to evaluate the patient's satisfaction with postoperative telemedicine visits in those undergoing knee or shoulder arthroscopy, and to analyze the factors associated with satisfaction with telemedicine. Methods: A prospective study was performed to evaluate satisfaction comparing postoperative telemedicine and in-office visits, in those undergoing shoulder and knee arthroscopy. Multiple factors were analyzed for correlation with satisfaction via multi-linear regression, including demographics such as gender, education, age, and race. Patients were also evaluated for preference for future visits with reference to the group in which they were placed. Results: Overall, 215 patients were included with a subgroup analysis of 93 patients receiving telemedicine visits. Patients reported overall similar satisfaction with telemedicine visits after shoulder and knee arthroscopy, with a high level of satisfaction seen in both. Female sex was found to be associated with decreasing satisfaction with telemedicine visits (p = 0.036). In addition, as a whole, the cohort was found to prefer future visits to be the same as the group they were placed in, but females statistically did not have this preference for their familiar group and were skewed toward the preference of in-person visits (p = 0.377). Conclusions: Our study found that female patients were less likely to be satisfied with postoperative telemedicine visits after knee or shoulder arthroscopy. Further, females were also less likely to indicate preference for future telemedicine visits. In contrast, education, history of prior surgery, age, and race were not associated with postoperative satisfaction. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the variation in tibial tubercle sagittal alignment in patients with and without patellofemoral (PF) cartilage wear. Methods: This was a single-centre, retrospective review of patients that underwent a cartilage restoration procedure for isolated PF cartilage wear from 2014 to 2020. Patients were matched in a 1:2 ratio for age, sex and BMI to partial meniscectomy patients as controls. The sagittal TT-TG (sTT-TG) distance was measured on preoperative axial T2 magnetic resonance imaging (MRI) and was defined as the distance between a point at the nadir of the trochlear cartilage and the most anterior point of the tibial tubercle. Results: One hundred and forty patients (47 cartilage restoration, 94 meniscectomy) were included. Mean age, BMI, and height for the total cohort were 34.01 ± 8.7, 26.6 ± 6.4, and 173.0 ± 17.7 respectively, with 78 males (55%) and 63 females (45%). There were no significant differences between groups for age, BMI or sex (n.s). The cartilage restoration group (− 2.5 mm ± 5.9) was found to have a significantly more posterior (negative) sTT-TG compared to the meniscectomy group (1.72 mm ± 6.7) (p < 0.001). Interrater reliability was excellent (ICC = 0.931, p < 0.001). Patients with less than − 3.4 mm sTT-TG were 2.74 times more likely to have a cartilage restoration procedure compared to those with greater than − 3.4 mm (OR 2.7, 95% CI 1.3–5.85). Patients with < − 10 mm posterior translation were 13.7× (CI 1.6–111.1) more likely to have a cartilage restoration procedure. Conclusion: Patients that underwent isolated cartilage restoration procedures had a significantly more posterior tibial tubercle than partial meniscectomy controls based on the sagittal TT-TG. The more posterior the tubercle, the more likely the patient had a cartilage restoration procedure. Surgeons should consider the sTT-TG measurement in patients presenting with anterior knee pain, particularly patellofemoral lesions. Level of evidence: III. [ABSTRACT FROM AUTHOR]

Background: Despite the widespread use and sales of cannabidiol (CBD) products in the United States, there is a paucity of literature to evaluate its effectiveness, safety, or ideal route of administration for postoperative pain. Purpose: To evaluate the potential analgesic effects of buccally absorbed CBD in patients who have undergone arthroscopic rotator cuff repair (ARCR). Study Design: Randomized controlled trial; Level of evidence, 1. Methods: This was a US Food and Drug Administration–sanctioned, multicenter, placebo-controlled, randomized, double-blinded trial conducted in patients undergoing ARCR. Patients aged from 18 to 75 years undergoing ARCR were prospectively enrolled and randomized to the control and experimental groups. The experimental group received an oral, buccally absorbed tablet containing 25 mg of CBD 3 times a day if <80 kg, or 50 mg of CBD 3 times a day if >80 kg, for 14 days postoperatively, while the control group received an identical placebo. Patients were followed up on days 1, 2, 7, and 14, and visual analog scale (VAS) for pain scores, opioid consumption, and satisfaction with pain control were recorded. Additionally, liver function tests were conducted on days 7 and 14 to assess safety, and nausea was monitored. P <.05 was considered to be statistically significant. Results: Overall, 100 patients were recruited, with 1 patient being excluded, for a total of 99 patients. There were no significant differences in patient demographics between the 2 groups. On day 1, the VAS pain score was significantly lower in the CBD group than in the control group (4.4 ± 3.1 vs 5.7 ± 3.2, respectively; P =.04), although this difference was no longer present on day 2 (4.7 ± 2.8 vs 5.3 ± 2.6, respectively; P =.32). On both days 1 and 2, patient satisfaction with pain control was significantly higher in the CBD group than in the control group (day 1: 7.0 ± 3.0 vs 5.6 ± 3.7, respectively [ P =.04]; day 2: 7.3 ± 2.5 vs 6.0 ± 3.3, respectively [ P =.03]). The quantity of opioids consumed was low in both groups, and there were no statistically significant differences in opioid consumption (P >.05). On days 7 and 14, there were no statistically significant differences in VAS scores, opioid consumption, or patient satisfaction with pain control between the CBD and control groups (P >.05 for all). There were no significant differences in liver function test results postoperatively (P >.05). Conclusion: Buccally absorbed CBD demonstrated an acceptable safety profile and showed significant promise in the reduction of pain in the immediate perioperative period after ARCR compared with the control. Further studies are currently ongoing to confirm dosing and effectiveness in other orthopaedic conditions. Registration: NCT04672252 (ClinicalTrials.gov identifier). [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to analyze patients that did not return to play (RTP) following arthroscopic Bankart repair (ABR) compared to those who did RTP, and analyze factors associated with not returning to play.Methods: A retrospective review of patients who underwent ABR, and subsequently did not RTP after a minimum of 24-month follow-up was performed. Additionally, these were pair matched in a 3:1 ratio for age, gender, sport and level of pre-operative play with a control group who RTP. Patients were evaluated for their psychological readiness to return to sport using the SIRSI score. Multivariate regression models were used to evaluate factors affecting RTP.Results: The study included a total of 52 patients who were unable to RTP and 156 who returned to play. Ten patients (19.2 %) who did not RTP passed the SIRSI benchmark of 56 with a mean overall score of 39.8 ± 24.6, in those who returned 73.0 % passed the SIRSI benchmark of 56 with a mean overall score of 68.9 ± 22.0 (p < 0.0001 for both). The most common primary reasons for not returning were 27 felt physically unable to return, whilst 21 felt it was a natural end to their career or their lifestyle had changed. Multi-logistic regression revealed that 4 of the 12 components of the SIRSI score (p < 0.05 for all) and SSV (p = 0.0049), were the factors that were associated with RTP.Conclusion: Following ABR, those that do not return to play exhibit poor psychological readiness to return to play, with multi-linear regression revealing the SIRSI questions associated with fear of re-injury were associated with a lower rate of RTP. Additionally, functional limitations were found to be associated with a lower rate of RTP.Level Of Evidence: Level III; Retrospective Comparative Cohort Study. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to evaluate the mid-term results of posterior medial meniscal root tear (PMMRT) repair through assessment of functional outcome scores and magnetic resonance imaging (MRI). Methods: This was a single-center, retrospective study evaluating patients that had undergone a PMMRT. This was a follow-up to a previously published 2-year outcome study (all original patients were invited to participate). Clinical outcomes included pre- and postoperative International Knee Documentation Committee (IKDC) and Lysholm scores. Root healing, meniscal extrusion, and cartilage degeneration via International Cartilage Repair Society Scale (ICRS) grades were assessed on MRI by two musculoskeletal fellowship-trained radiologists. Results: 10 of the original study's 18 patients were able to participate. Mean age and BMI was 48.4 ± 12.0 years and 29.5 ± 4.5, respectively, with mean follow-up 65.5 ± 8.3 months (range 52.0–75.8) (60% female). The IKDC significantly increased from 43 ± 13 preoperatively to 75 ± 16 at 5-year follow-up (p < 0.001). There was no significant change in IKDC score between 2-year and 5-year follow-up [75 ± 16 vs 73 ± 20, (n.s)]. The Lysholm also significantly increased between preoperative and 5-year follow-up (49 ± 7 vs 84 ± 11, p < 0.001). There was no significant change between Lysholm score at 2-year and 5-year follow-up [84.0 ± 11 vs 82 ± 13, (n.s)]. Mean extrusion did not significantly change from the preoperative state to 5-year follow-up [4.80 mm ± 1.9 vs 5.0 mm ± 2.5, (n.s.)]. Extrusion also did not significantly change between 2-and 5-year follow-up [6.1 ± 3.2 mm vs 5.0 mm ± 2.5, (n.s.)]. No patients with > 3 mm of extrusion on preoperative MRI had < 3 mm of extrusion on postoperative MRI. Both medial femoral condyle and medial tibial plateau ICRS grades significantly increased from preoperative to 2-year follow-up (p = 0.038, p = 0.023, respectively). Medial femoral condyle and medial tibial plateau ICRS grades again significantly increased between 2-year and 5-year follow-up (p = 0.014, p = 0.034). Conclusion: Patients treated with the transtibial suture pullout technique with two locking cinch sutures had maintenance of clinical outcome improvements at 5-year follow-up. However, extrusion was widely prevalent, with worsening progression of femoral and tibial chondral disease. Level of Evidence: Level 4. [ABSTRACT FROM AUTHOR]

Background: Performing open subpectoral biceps tenodesis in overhead athletes with a superior labrum anterior to posterior (SLAP) tear may affect their ability to return to overhead sports. Purpose: To investigate clinical outcomes in overhead athletes undergoing biceps tenodesis for the treatment of symptomatic, isolated SLAP tears involving the biceps-labral complex. Study Design: Case series; Level of evidence, 4. Methods: A retrospective review of overhead athletes who underwent biceps tenodesis for a SLAP tear was performed. The American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) score for pain, subjective shoulder value (SSV), patient satisfaction, willingness to undergo surgery again, revision procedures, and return to play were evaluated. Psychological readiness to return to sport was evaluated using the SLAP–Return to Sport after Injury (SLAP-RSI) score. A P value of <.05 was considered to be statistically significant. Results: The current study included 44 overhead athletes. The mean age was 34.9 years (range, 16-46 years), 79.5% were male, and the mean follow-up was 49.0 months (range, 18-107 months). Overall, 81.8% of patients returned to play their overhead sport after biceps tenodesis, and 59.1% of patients returned to the same or higher level of play. It took patients, on average, 8.7 months to return to play after biceps tenodesis. The mean SLAP-RSI score was 69.4, and 70.5% of patients passed the SLAP-RSI threshold of 56. The mean ASES score, VAS score, SSV, and satisfaction were 92.0, 0.8, 80.6, and 87.9%, respectively. No patients in our cohort required revision surgery. Conclusion: This study found that athletes undergoing biceps tenodesis for the treatment of a symptomatic, isolated SLAP tear had a high rate of return to play, good functional outcomes, and a low rate of revision surgery.

Purpose: The purpose of this study was to identify if the location of posterolateral corner (PLC) injury was predictive of clinical common peroneal nerve (CPN) palsy. Methods: A retrospective chart review was conducted of patients presenting to our institution with operative PLC injuries. Assessment of concomitant injuries and presence of neurologic injury was completed via chart review and magnetic resonance imaging (MRI) review. A fellowship-trained musculoskeletal radiologist reviewed the PLC injury and categorized it into distal, middle and proximal injuries with or without a biceps femoral avulsion. The CPN was evaluated for signs of displacement or neuritis. Results: Forty-seven operatively managed patients between 2014 and 2019 (mean age-at-injury 29.5 ± 10.7 years) were included in this study. Eleven (23.4%) total patients presented with a clinical CPN palsy. Distal PLC injuries were significantly associated with CPN palsy [9 (81.8%) patients, (P = 0.041)]. Nine of 11 (81.8%) patients with CPN palsy had biceps femoral avulsion (P = 0.041). Of the patients presenting with CPN palsy, only four (36.4%) patients experienced complete neurologic recovery. Three of 7 patients (43%) with an intact CPN had full resolution of their clinically complete CPN palsy at the time of follow-up (482 ± 357 days). All patients presenting with a CPN palsy also had a complete anterior cruciate ligament (ACL) rupture in addition to a PLC injury (P = 0.009), with or without a posterior cruciate ligament (PCL) injury. No patient presenting with an isolated pattern of PCL-PLC injury (those without ACL tears) had a clinical CPN palsy. Conclusion: Distal PLC injuries have a strong association with clinical CPN palsy, with suboptimal resolution in the initial post-operative period. Specifically, the presence of a biceps femoris avulsion injury was highly associated with a clinical CPN palsy. Additionally, CPN palsy in the context of PLC injury has a strong association with concomitant ACL injury. Furthermore, the relative rates of involvement of the ACL vs. PCL suggest that specific injury mechanism may have an important role in CPN palsy. Level of evidence: IV. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective comparative; LOE-3.Objective: The purpose of this study was to investigate what effect, if any, an institutional opioid reduction prescribing policy following one- or two-level lumbar fusion has on Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey results.Summary Of Background Data: Previous research has demonstrated that high levels of opioid-prescribing may be related, in part, to a desire to produce superior patient satisfaction.Methods: A retrospective review of prospectively collected data was conducted on patients who underwent one- or two-level lumbar fusions L3-S1 between October 2014 and October 2019 at a single institution. Patients with complete survey information were included in the analysis. Patients with a history of trauma, fracture, spinal deformity, fusions more than two levels, or prior lumbar fusion surgery L3-S1 were excluded. Cohorts were based on date of surgery relative to implementation of an institutional opioid reduction policy, which commenced in October 1, 2018. To better compare groups, opioid prescriptions were converted into milligram morphine equivalents (MME).Results: A total of 330 patients met inclusion criteria: 259 pre-protocol, 71 post-protocol. There were 256 one-level fusions and 74 two-level fusions included. There were few statistically significant differences between groups with respect to patient demographics (P > 0.05) with the exception of number of patients who saw the pain management service, which increased from 36.7% (95) pre-protocol to 59.2% (42) post-protocol; P < 0.001. Estimated blood loss (EBL) decreased from 533 ± 571 mL to 346 ± 328 mL (P = 0.003). Percentage of patients who underwent concomitant laminectomy decreased from 71.8% to 49.3% (P < 0.001). Average opioids prescribed on discharge in the pre-protocol period was 534 ± 425 MME, compared to after initiation of the protocol, that is 320 ± 174 MME (P < 0.001). There was no statistically significant difference with respect to satisfaction with pain control, 4.49 ± 0.85 pre-protocol versus 4.51 ± 0.82 post-protocol (P = 0.986).Conclusion: A reduction in opioids prescribed at discharge after one- or two-level lumbar fusion is not associated with any statistically significant change in patient satisfaction with pain management, as measured by the HCAHPS survey.Level of Evidence: 3.

Purpose: Medial patellofemoral ligament reconstruction (MPFLR) is often indicated in athletes with lateral patellar instability to prevent recurrence and allow for a successful return to play. In this patient population, the ability to return to play is one of the most important clinical outcomes. The purpose of the current study was to analyze the characteristics of patients who were unable return to play following MPFL reconstruction. Methods: A retrospective review of patients who underwent MPFL reconstruction and subsequently did not return to play after a minimum of 12-months of follow-up was performed. Patients were evaluated for their psychological readiness to return to sport using the MPFL-Return to Sport after Injury (MPFL-RSI) score, which is a modification of the ACL-RSI score. A MPFL-RSI score > 56 is considered a passing score for being psychologically ready to return to play. Additionally, reasons for not returning to play including Visual Analog Scale for pain (VAS), Kujala score, satisfaction, and recurrent instability (including dislocations and subluxations) were evaluated. Results: The study included a total of 35 patients who were unable to return to play out of a total cohort of 131 patients who underwent MPFL reconstruction as treatment for patellar instability. Overall, 60% were female with a mean age of 24.5, and a mean follow-up of 38 months. Nine patients (25.7%) passed the MPFL-RSI benchmark of 56 with a mean overall score of 44.2 ± 21.8. The most common primary reasons for not returning to play were 14 were afraid of re-injury, 9 cited other lifestyle factors, 5 did not return due to continued knee pain, 5 were not confident in their ability to perform, and 2 did not return due to a feeling of instability. The mean VAS score was 1.9 ± 2.3, the mean Kujala score was 82.5 ± 14.6, and the mean satisfaction was 76.9%. Three patients (8.7%) reported experiencing a patellar subluxation event post-operatively. No patient sustained a post-operative patellar dislocation. Conclusion: Following MPFL reconstruction, patients that do not return to play exhibit poor psychological readiness with the most common reason being fear of re-injury. Level of evidence: IV.

Background:Owing to the COVID-19 pandemic, there has been a large shift in health care toward virtual platforms. This study analyzed patient and physician satisfaction with telehealth during the height of the pandemic within the division of sports medicine. Methods:All sports medicine patients who completed a telemedicine visit from March 30, 2020, through April 30, 2020, were sent a 14-question Likert scale (1–5/5) survey. Sports medicine physicians who used telemedicine were sent a separate 14-question Likert scale (1–5/5) survey at the end of the study period. Factors influencing patient satisfaction were determined using a multivariate linear regression model. Results:A total of 143 patients and 9 sports medicine attendings completed the surveys. Most patients were "satisfied" (4/5) or "very satisfied" (5/5) (88.8%). A multivariate linear regression determined that patients who believed they had a greater ability to adopt new technology and were more effective at communicating questions/concerns to their physicians had greater satisfaction (p = 0.009 and p = 0.015, respectively). Most physicians were either "satisfied" (4/5) or "very satisfied" (5/5) (75.0%). On average, physicians felt that physical examinations conducted through telemedicine were "moderately effective" (2.75/5.00 ± 1.3), that they were "fairly confident" (3.86/5.00 ± 0.83) in their diagnoses, and that most sports medicine attendings plan to use telemedicine in the future (87.5%). Conclusion:Telehealth emerged as a valuable tool for the delivery of health care to sports medicine patients during the COVID-19 pandemic. Patients and physicians reported high levels of satisfactions with its use, and this study further identifies areas that can improve the patient and physician experience. [ABSTRACT FROM AUTHOR]

Background: It is unclear whether leukocyte-poor (LP) or leukocyte-rich (LR) varieties of platelet-rich plasma (PRP) as an adjuvant to arthroscopic rotator cuff repair (ARCR) result in improved tendon healing rates. Purpose: To perform a network meta-analysis of the randomized controlled trials in the literature to ascertain whether there is evidence to support the use of LP- or LR-PRP as an adjunct to ARCR. Methods: The literature search was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Randomized controlled trials comparing LP- or LR-PRP with a control alongside ARCR were included. Clinical outcomes, including retears and functional outcomes, were compared using a frequentist approach to network meta-analysis, with statistical analysis performed using R. The treatment options were ranked using the P-score. Results: There were 13 studies (868 patients) included, with 9 studies comparing LP-PRP with a control and 4 studies comparing LR-PRP with a control. LP-PRP was found to significantly reduce the rate of retear and/or incomplete tendon healing after fixation, even among medium-large tears; it also improved outcomes on the visual analog scale for pain, Constant score, and University of California Los Angeles score. LP-PRP had the highest P-score for all treatment groups. LR-PRP did not result in any significant improvements over the control group, except for visual analog scale score for pain. However, post hoc analysis revealed that LP-PRP did not lead to significant improvements over LR-PRP in any category. Conclusion: The current study demonstrates that LP-PRP reduces the rate of retear and/or incomplete tendon healing after ARCR and improves patient-reported outcomes as compared with a control. However, it is still unclear whether LP-PRP improves the tendon healing rate when compared with LR-PRP. [ABSTRACT FROM AUTHOR]

The purpose of this study was to compare the 90-day complication rate between the open and arthroscopic Latarjet procedure. A retrospective review of patients who underwent an open or arthroscopic Latarjet procedure at NYU Langone Health between 2012 and 2019 was performed. The complications, readmissions, and reoperations within 90 days were assessed. Outcomes were compared between the two approaches, and a p value of < 0.05 was considered to be statistically significant. The study included 150 patients (open: 110; arthroscopic: 40), with no patients lost to follow-up within the first 90 days. Both cohorts were similar in terms of patient demographics. No intra-operative complications were observed in either group. Overall, there were 4 post-operative complications with the open approach and 2 with the arthroscopic approach (3.6% and 5.0%, respectively; n.s.) during the study period. Three patients required a readmission within the 90-day period; one patient in both groups required a revision Latarjet for graft fracture, and one patient in the open Latarjet required irrigation and debridement for deep infection (n.s.). With the open approach, there were 2 (2.3%) wound complications, 1 graft complication, and 1 (1.1%) nerve injury. With the arthroscopic approach, there was 1 (2.8%) wound complication and 1 (2.8%) hardware complication. The safety, and 90-day complication and readmission profile of arthroscopic Latarjet is similar to open Latarjet procedure. Level of evidence: Level III. [ABSTRACT FROM AUTHOR]

Background:A major byproduct of the recent coronavirus disease 2019 (COVID-19) pandemic has been the accelerated adoption of telemedicine within orthopedic practices. Introduction:The purpose of the study is to evaluate satisfaction associated with telemedicine and to determine how telemedicine is used by orthopedic surgeons in response to social distancing efforts necessitated by the COVID-19 pandemic. Methods:We developed a survey to evaluate surgeon's perception of telemedicine during the COVID-19 pandemic. The survey consisted of four major sections focusing on (1) surgeon characteristics and current use of telemedicine, (2) telemedicine for new patients, (3) telemedicine for routine follow-up patients, and (4) telemedicine for postoperative patients. Results:We collected 268 survey responses. Overall, 84.8% of surgeons were using telemedicine, but only 20.5% of surgeons were using it before the COVID-19 pandemic. The overall satisfaction with telemedicine was 70.3% ± 20.9%. Of those who use telemedicine, 75% currently use it for new patients, 86.6% currently use it for routine follow-up patients, and 80.8% currently use it for postoperative patients (p = 0.01). Surgeons had higher satisfaction with building rapport and performing physical examination maneuvers for either routine follow-up or postoperative patients than for new patients (p < 0.0001 for both). However, satisfaction with obtaining imaging did not differ among the cohorts (p = 0.36). Surgeons felt they are more likely to continue to use telemedicine after the COVID-19 pandemic for either routine follow-up or postoperative patients than for new patients (p < 0.0001). Discussion:Owing to challenges posed by the COVID-19 pandemic, telemedicine use has increased substantially among orthopedic surgeons in recent months. Conclusions:Our study established that physician implementation of telemedicine has increased significantly as a result of the COVID-19 pandemic, with the majority of surgeons satisfied with its use in their practice, and plan on incorporating telemedicine in their practices beyond the pandemic.

Background: Telemedicine has increasingly been considered as a viable alternative to traditional office-based health care, including postoperative follow-up visits. The purpose of the present study was to determine if patient satisfaction with overall care is equivalent for telemedicine follow-up (i.e., synchronous face-to-face video) and office-based follow-up after arthroscopic meniscectomy and repair.Methods: Patients were prospectively enrolled from August 1, 2019, to March 1, 2020. Patients were included who were ≥18 years old, consented to isolated arthroscopic meniscal repair or meniscectomy, and were able to properly utilize telemedicine software on a computer, tablet, or smartphone with a built-in camera. Patient demographic data, including complication events and postoperative satisfaction data, were recorded and analyzed for significance.Results: One hundred and fifty patients were enrolled in the study, of whom 122 (81.3%) were included in the final analysis. There were no significant differences between groups in terms of patient demographics or satisfaction scores. Patient satisfaction with overall care was equivalent based on the results of two 1-sided t-test analysis for equivalence (9.77 ± 0.60 in the office-based group versus 9.79 ± 0.53 in the telemedicine group; p < 0.001). When patients were asked to indicate their preferred follow-up type with the options listed as the type they received versus an alternative, 58 patients (84.1%) in the office-based group preferred their received type of follow-up, whereas 42 (79.2%) in the telemedicine group preferred their received follow-up (p = 0.493). There were no significant differences between groups in terms of complications (p > 0.05).Conclusions: The present study showed that patient satisfaction with overall care is equivalent between telemedicine and office-based follow-up in the immediate postoperative period following an arthroscopic meniscal surgical procedure, and should be considered a reasonable alternative to the traditional in-office modality.Level Of Evidence: Therapeutic Level I.

Case: A 41-year-old man presented with a transverse patella fracture and proximal patellar tendon avulsion after a fall from standing. Disruption of the extensor mechanism of the knee at multiple points is rare. He was treated operatively for his patella fracture and patellar tendon avulsion but experienced early failure of the patellar tendon fixation requiring reoperation. Both components of injury ultimately healed, and he returned to function. Conclusion: This case describes a rare presentation of an uncommon injury pattern affecting the extensor mechanism. This is the first report to describe multifocal failure of the extensor chain from a low-energy mechanism. [ABSTRACT FROM AUTHOR]

Background: With the increasing utilization of patient satisfaction as a metric for clinical care, there is growing interest in techniques that can be used to improve satisfaction in patients undergoing surgery. The purpose of this trial was to assess the impact of day-of-surgery video and phone calls on patient satisfaction.Methods: We enrolled 251 patients undergoing outpatient orthopaedic surgery with 3 participating surgeons. Surgeons were randomized to 1 of 3 patient communication modalities: no contact (standard of care), phone call, or video call. Several hours following discharge on the day of surgery, the surgeons contacted patients according to their assigned treatment group. At the initial postoperative office visit, satisfaction outcomes were assessed using the Consumer Assessment of Healthcare Providers and Systems Surgical Care (S-CAHPS) survey and an additional satisfaction questionnaire.Results: Fifty-nine (97%) of 61 patients in the no-contact group, 118 (99%) of 119 patients in the phone group, and 71 (100%) of 71 patients in the video group completed follow-up assessment. The S-CAHPS top-box response rate in both the video group (0.86 ± 0.14, p < 0.001) and the phone group (0.84 ± 0.17, p < 0.001) was greater than in the no-contact group (0.68 ± 0.26). When asked to rate satisfaction with overall care, a greater proportion of patients in the video group (85.9%) gave the top-box response compared with both the phone group (71.8%, p = 0.040) and the no-contact group (60.7%, p = 0.002). Among the patients in the video group, 62.0% indicated that they would prefer a video call in future encounters with their surgeon compared with 1.8% of patients in the no-contact group (p < 0.001) and 1.7% of patients in the phone group (p < 0.001).Conclusions: Phone and video calls following discharge are an effective way of enhancing patient satisfaction with the clinical care experience as measured by the S-CAHPS survey. In terms of satisfaction with overall care, video calls may be superior to phone calls.Level Of Evidence: Therapeutic Level I.

Background: The gold-standard method for collecting patient-reported outcomes (PROs) is the prospective assessment of preoperative to postoperative change. However, this method is not always feasible because of unforeseen cases or emergencies, logistical and infrastructure barriers, and cost issues. In such cases, a retrospective approach serves as a potential alternative, but there are conflicting conclusions regarding the reliability of the recalled preoperative PROs after orthopaedic procedures. Purpose: To assess the agreement between prospectively and retrospectively collected PROs for a common, low-risk procedure. Study Design: Cohort study (Diagnosis); Level of evidence, 3. Methods: Patients who underwent arthroscopic rotator cuff repair between May 2012 and September 2017 at the study institution were identified. All of the patients completed the American Shoulder and Elbow Surgeons (ASES) Standard Shoulder Assessment Form preoperatively at their preassessment appointment. Patients were then contacted in the postoperative period and asked to recall their preoperative condition while completing another ASES form. Results: A total of 84 patients completed the telephone survey and were included in this analysis (mean age, 57.40 ± 9.96 years). The mean duration of time from onset of shoulder symptoms to surgery was 9.13 ± 9.08 months. The mean duration of time between surgery and recall ASES administration was 39.12 ± 17.37 months. The mean recall ASES score was significantly lower than the preoperative ASES score (30.69 ± 16.93 vs 51.42 ± 19.14; P <.001). There was poor test-retest reliability between preoperative ASES and recall ASES (intraclass correlation coefficient, 0.292; 95% CI, –0.07, 0.57; P =.068). Greater age at the time of recall, a shorter symptomatic period before surgery, and less severe preoperative shoulder dysfunction were associated with a greater difference between preoperative ASES and recall ASES. Conclusion: Retrospectively reported PROs are subject to significant recall bias. Recalled PROs were almost always lower than their prospectively recorded counterparts. Recalled PROs are more likely to be accurate when reported by younger patients, those with a longer duration of symptoms, and those with more severe preoperative conditions. [ABSTRACT FROM AUTHOR]

Purpose: To utilize MRI to assess the relationship between BMI, peripheral soft tissue composition about the knee, and surgical outcomes in patients undergoing primary ACL reconstruction. It was hypothesized that a fatty periarticular soft tissue composition may be better than BMI at predicting poor outcomes after ACL reconstruction.Methods: Fifty-eight patients who underwent primary acute ACL reconstruction were identified from the surgical database and their data were retrospectively reviewed. Patients were selected based on availability of 2-year IKDC outcome scores, BMI data, and preoperative MRI studies. To approximate peripheral soft tissue composition, novel measurements of axial MRI images were employed using PACS ROI measurement tool. Relationships were assessed between IKDC outcome scores and measures of body habitus including BMI, total knee area, knee fatty-connective tissue area, and fatty-connective tissue to bone size ratio.Results: The median BMI was 24.3 kg/m2 (range 18.5-36.9). Median IKDC score was 81.0 (range 46-100). BMI was correlated with total knee area (R = 0.72) and periarticular fat (R = 0.53). Neither continuous BMI (n.s.) nor total knee area (n.s.) was predictor of IKDC outcomes scores. Periarticular fatty-connective tissue trended towards predicting negative outcomes (n.s.). Periarticular fatty-connective tissue to bone size ratio was a significant negative predictor of IKDC scores (p = 0.03). Patients with more fat than bone on axial MRI (ratio > 1, N = 34) reported a lower mean IKDC score compared to patients with a ratio < 1 (N = 24) (77.2 vs. 87.7, p = 0.0028). The top quartile (N = 14) of these ratios reported a mean IKDC score of 68.9, compared to 87.3 of the bottom quartile (p = 0.0001).Conclusions: Periarticular soft tissue composition, as approximated by the novel MRI analysis of this study, is a better predictor of outcomes following ACL reconstruction than is BMI. This information can be utilized in guiding surgeon and patient expectations following surgery, either via a direct application of these measurements or heightened awareness of the importance of peripheral body habitus.Level Of Evidence: III.

Objective: To review the MRI appearance of medial patellofemoral capsuloligamentous plication (also known as reefing or imbrication) for proximal patellar realignment in patients with patellofemoral instability.Materials and Methods: Retrospective analysis of our surgical and PACS databases identified cases of medial plication performed between June 2011 and July 2016. Pre- and postoperative MRI characteristics were reviewed. Correlation was made with operative reports and clinical records to define postoperative appearances on MRI.Results: Forty-one patients underwent medial plication during the study period; 29 were excluded owing to a lack of postoperative imaging. Ultimately, 12 knees were included in 11 patients who had postoperative MRI studies available (8 women and 3 men, mean age 27.3 ± 10.2 years). Ten (83%) of the surgeries were performed open and 2 (17%) arthroscopically. There were differences in the post-surgical MRI appearance of medial plications carried out after surgery using the open and arthroscopic techniques. The open technique produces a "heaped up" distal vastus medialis obliquus (VMO) with centralized patellar insertion (100%), which was absent in the case of arthroscopic plication, where subtle medial retinaculum thickening was demonstrated without alteration of its patellar insertion. The mean postoperative lateral patellar and patellofemoral congruence angles measured 2.5° ± 5.6° and 12.4° ± 19.9° respectively. A significant association was found regarding change in patellofemoral alignment (p = 0.018 and p = 0.004 respectively).Conclusion: The MRI appearance of medial plication is not well described in the radiology literature; radiologists should be familiar with anticipated post-plication findings to avoid potential confusion for pathology and allow more accurate interpretation of postoperative imaging findings from this common surgery.

Purpose: The purpose of the current study was to evaluate the short-term results of meniscal root repair surgery, assessing clinical and radiographic outcomes, utilizing MRI to assess root healing and extent of post-operative extrusion.Methods: This was a single-center, retrospective study evaluating patients who had undergone a medial meniscus posterior root repair using a transtibial pullout technique with two locking cinch sutures. Demographic data were collected from patient charts. Clinical outcomes were assessed with pre- and post-operative IKDC and Lysholm scores. Pre-op scores were taken at the patients' initial clinical visit, mean 1.55 months prior to surgery (± 1.8 months, min 0.3, max 7.3). Radiographic outcomes were assessed with MRI evaluation of root healing, meniscal extrusion, and cartilage degeneration using ICRS criteria. Tunnel placement was evaluated and compared to the anatomic footprint.Results: Eighteen patients (47.2 years ± 11.9) were evaluated at mean follow-up of 24.9 months (± 7.2, min 18.4, max 35.6). The IKDC score significantly increased from 45.9 (± 12.6) pre-operatively to 76.8 (± 14.7) post-operatively (p < 0.001). Lysholm scores also increased from 50.9 (± 7.11) to 87.1 (± 9.8) (p < 0.001). Mean tunnel placement was 5.3 mm (± 3.5, range 0-11.8) away from the anatomic footprint. Mean extrusion increased from 4.74 mm (± 1.7) pre-operatively to 5.98 (± 2.8) post-operatively (p < 0.02). No patients with > 3 mm of extrusion on pre-operative MRI had < 3 mm of extrusion on post-operative MRI. Both medial femoral condyle and medial tibial plateau ICRS grades worsened significantly (p < 0.02 and p < 0.01, respectively). On MRI, one root appeared completely healed, 16 partially healed, and one not healed.Conclusion: Patients treated with the transtibial suture pull-out technique with two locking cinch sutures had improved clinical outcomes, but only partial healing in the majority of cases, increased extrusion, and progression of medial compartment cartilage defect grade on follow-up MRI. Patients should be counseled that although clinical outcomes in the short term may be optimistic, long-term outcomes regarding progression to degenerative arthritis may not be as predictable.Clinical Level Of Evidence: III.

Purpose: The purpose of this study was to quantify the regional histology of the long head of the biceps tendon (LHBT) and compare the histopathology present to clinical findings in patients with rotator cuff tears and SLAP lesions.Methods: Prospectively enrolled patients undergoing an open subpectoral LHBT tenodesis in the setting of a rotator cuff (RTC) tear or SLAP lesion. Perioperative data were collected and the excised LHBT was analyzed by a fellowship trained pathologist. Tendons were sectioned into proximal (biceps anchor), middle (bicipital groove), and distal (myotendinous junction) portions. Sections were stained with Movat's pentachrome stain and digitized for analysis. Comparisons were made between the histologic findings present in the setting of a rotator cuff tear with those seen in the setting of a SLAP tear.Results: 39 tendons were analyzed: 20 from patients with SLAP lesions (mean age of 44.7 years, range 23-60 years) and 19 from patients with rotator cuff tears (mean age of 58.7 years, range 43-71). Patients with the most pathologic tendons in the bicipital groove were significantly older (59.4 vs. 50.4 years; p < 0.05), reported higher pre-operative VAS scores (6.6 vs. 5.0; p < 0.02), and demonstrated lower pre-operative ASES scores (41.6 vs. 50.7; p < 0.05). The RTC group showed significantly more mucinous degeneration at both the proximal (p < 0.03) and the middle (p < 0.01) tendon portions compared to the SLAP group. In both groups, the portions of proximal tendon showed significantly (p < 0.05) more mucinous degeneration than distal portions.Conclusion: Regional histologic differences exist in the LHBT. Rotator cuff patients showed the most degenerated tendon in the bicipital groove and these patients tended to be older and have higher VAS and lower ASES scores. Surgeons should consider performing a subpectoral biceps tenodesis as the bicipital groove portion of the tendon may be very degenerated, especially in patients with rotator cuff disease. Additional research is warranted to distinguish whether treating the biceps differently in distinct geographic regions affects patient outcomes.Level Of Evidence: II. [ABSTRACT FROM AUTHOR]
