Realistic looking humanoid love and sex dolls have been available on a somewhat secretive basis for at least three decades. But today the industry has gone mainstream with North American, European, and Asian producers using mass customization and competing on the bases of features, realism, price, and depth of product lines. As a result, realistic life size artificial companions are becoming more affordable to purchase and more feasible to patronize on a service basis. Sexual relations may be without equal when it comes to emotional intimacy. Yet, the increasingly vocal and interactive robotic versions of these dolls, feel nothing. They may nevertheless induce emotions in users that potentially surpass the pleasure of human-human sexual experiences. The most technologically advanced love and sex robots are forecast to sense human emotions and gear their performances of empathy, conversation, and sexual activity accordingly. I offer a model of how this might be done to provide a better service experience. I compare the nature of resulting “artificial emotions” by robots to natural emotions by humans. I explore the ethical issues entailed in offering love and sex robot services with artificial emotions and offer a conclusion and recommendations for service management and for further research.

Rituals, particularly religious rituals, may play a significant role in times of crises. Often, these rituals undergo revision to adapt to the changing needs of the time. This article investigates recent unofficially revised Hindu religious rituals as performed during the COVID-19 pandemic. The multifarious creative interplay between Hindu tradition and change is illustrated through four cases: the religious festival of Durga Puja, the devotional songs or bhajans, the ritual of lighting lamps or diyas, and the fire rituals or havans. The authors offer a systematic discourse analysis of online news articles and YouTube posts that illuminate several aspects of ritual revision during unsettled times. They focus on the changes that were made to ritual elements: who controlled these alterations, how these modifications were made, and what potential benefits these revisions offered to the community of ritual participants. The authors highlight public policy implications regarding the involvement of diverse social actors, the creation of faith in science, the creation of feelings of unity and agency, and the amplification of local ritual modifications on a national scale.

Background: The extent to which concomitant cartilage repair provides an improvement in clinical outcomes after osteotomy is unclear. Purpose: To compare studies reporting clinical outcomes after isolated osteotomy with or without cartilage repair for osteoarthritis (OA) or focal chondral defects (FCDs) of the knee joint. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by searching PubMed, Cochrane Library, and Embase databases. The search was done to identify comparative studies that directly compared outcomes between isolated osteotomy—high tibial osteotomy or distal femoral osteotomy—and osteotomy with concomitant cartilage repair for OA or FCDs of the knee joint. Patients were evaluated based on reoperation rate, magnetic resonance observation of cartilage repair tissue score, macroscopic International Cartilage Regeneration & Joint Preservation Society score, and patient-reported outcomes. Results: In total, 6 studies—level 2 evidence (n = 2);, level 3 evidence (n = 3);, and level 4 evidence (n = 1)—met the inclusion criteria, including a total of 228 patients undergoing osteotomy alone (group A) and 255 patients undergoing osteotomy with concomitant cartilage repair (group B). The mean patient age was 53.4 and 54.8 years, respectively, and the mean preoperative alignment was 6.6° and 6.7° of varus in groups A and B, respectively. The mean follow-up time was 71.5 months. All studies assessed medial compartment lesions with varus deformity. One study compared osteotomy alone for patients with medial compartment OA versus osteotomy with autologous chondrocyte implantation for patients with FCDs of the medial compartment. Three other studies included a heterogeneous cohort of patients with OA and FCDs in both groups. Only 1 study isolated its comparison to patients with medial compartment OA and 1 study isolated its comparison to patients with FCDs. Conclusion: There is limited evidence with substantial heterogeneity between studies on clinical outcomes after osteotomy alone versus osteotomy with cartilage repair for OA or FCDs of the knee joint. At this time, no conclusion can be made regarding the role of additional cartilage procedures in treating medial compartment OA or FCDs. Further studies are needed that isolate specific disease pathology and specific cartilage procedures.

Background: Multiple studies have compared outcomes among patients undergoing revision anterior cruciate ligament reconstruction (ACLR) with autograft versus allograft, but these data are inconsistently reported and long-term outcomes depending on graft type are yet to be determined. Purpose: To perform a systematic review of clinical outcomes after revision ACLR (rACLR) with autograft versus allograft. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature was performed by searching PubMed, the Cochrane Library, and Embase to identify studies that compared the outcomes of patients undergoing rACLR with autograft versus allograft. The search phrase used was autograft allograft revision anterior cruciate ligament reconstruction. Graft rerupture rates, return-to-sports rates, anteroposterior laxity, and patient-reported outcome scores (subjective International Knee Documentation Committee, Tegner, Lysholm, and Knee injury and Osteoarthritis Outcome Score) were evaluated. Results: Eleven studies met inclusion criteria, including 3011 patients undergoing rACLR with autograft (mean age, 28.9 years) and 1238 patients undergoing rACLR with allograft (mean age, 28.0 years). Mean follow-up was 57.3 months. The most common autograft and allograft types were bone–patellar tendon–bone grafts. Overall, 6.2% of patients undergoing rACLR experienced graft retear, including 4.7% in the autograft group and 10.2% in the allograft group ( P < .0001). Among studies that reported return-to-sports rates, 66.2% of patients with an autograft returned to sports as opposed to 45.3% of patients with an allograft ( P = .01). Two studies found significantly greater postoperative knee laxity in the allograft group as compared with the autograft group ( P < .05). Among all patient-reported outcomes, 1 study found 1 significant difference between groups: patients with an autograft had a significantly higher postoperative Lysholm score when compared with patients with an allograft. Conclusion: Patients undergoing revision ACLR with an autograft can be expected to experience lower rates of graft retear, higher rates of return to sports, and less postoperative anteroposterior knee laxity when compared with patients undergoing revision ACLR with an allograft.

Background: Arthroscopic stabilization has been established as a superior treatment option for primary glenohumeral instability when compared with immobilization in internal rotation. However, immobilization in external rotation (ER) has recently gained interest as a viable nonoperative treatment option for patients with shoulder instability. Purpose: To compare the rates of recurrent instability and subsequent surgery in patients undergoing treatment for primary anterior shoulder dislocation with arthroscopic stabilization versus immobilization in ER. Study Design: Systematic review; Level of evidence, 2. Methods: A systematic review was performed by searching PubMed, the Cochrane Library, and Embase to identify studies that’evaluated patients being treated for primary anterior glenohumeral dislocation with either arthroscopic stabilization or immobilization in ER. The search phrase used various combinations of the keywords/phrases “primary closed reduction,”“anterior shoulder dislocation,”“traumatic,”“primary,”“treatment,”“management,”“immobilization,”“external rotation,”“surgical,”“operative,”“nonoperative,” and “conservative.” Inclusion criteria included patients undergoing treatment for primary anterior glenohumeral joint dislocation with either immobilization in ER or arthroscopic stabilization. Rates of recurrent instability, subsequent stabilization surgery, return to sports, positive postintervention apprehension tests, and patient-reported outcomes were evaluated. Results: The 30 studies that met inclusion criteria included 760 patients undergoing arthroscopic stabilization (mean age, 23.1 years; mean follow-up time, 55.1 months) and 409 patients undergoing immobilization in ER (mean age, 29.8 years; mean follow-up time, 28.8 months). Overall, 8.8% of operative patients experienced recurrent instability at latest follow-up compared with 21.3% of patients who had undergone ER immobilization ( P < .0001). Similarly, 5.7% of operative patients had undergone a subsequent stabilization procedure at latest follow-up compared with 11.3% of patients who had undergone ER immobilization ( P = .0015). A higher rate of return to sports was found in the operative group ( P < .05), but no other differences were found between groups. Conclusion: Patients undergoing arthroscopic treatment for primary anterior glenohumeral dislocation with arthroscopic stabilization can be expected to experience significantly lower rates of recurrent instability and subsequent stabilization procedures compared with patients undergoing ER immobilization.

Background: The extent to which concomitant osteotomy provides an improvement in clinical outcomes after cartilage repair procedures is unclear. Purpose: To review the existing literature to compare clinical outcomes of patients undergoing cartilage repair of the tibiofemoral joint with versus without concomitant osteotomy. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by searching PubMed, the Cochrane Library, and Embase to identify studies that directly compared outcomes between cartilage repair of the tibiofemoral joint alone (group A) versus cartilage repair with concomitant osteotomy (high tibial osteotomy [HTO] or distal femoral osteotomy [DFO]) (group B). Studies on cartilage repair of the patellofemoral joint were excluded. The search terms used were as follows: osteotomy AND knee AND (“autologous chondrocyte” OR “osteochondral autograft” OR “osteochondral allograft” OR microfracture). Outcomes in groups A and B were compared based on reoperation rate, complication rate, procedure payments, and patient-reported outcomes (Knee injury and Osteoarthritis Outcome Score [KOOS], visual analog scale [VAS] for pain, satisfaction, and WOMAC). Results: Included in the review were 5 studies (1 level 2 study, 2 level 3 studies, 2 level 4 studies) with 1747 patients in group A and 520 patients in group B. The mean patient ages were 34.7 and 37.5 years in groups A and B, respectively, and the mean lesion sizes were 4.0 and 4.5 cm2, respectively. The mean follow-up time was 44.6 months. The most common lesion location was the medial femoral condyle (n = 999). Preoperative alignment averaged 1.8° and 5.5° of varus in groups A and B, respectively. One study found significant differences between groups in KOOS, VAS, and satisfaction, favoring group B. The reoperation rates were 47.4% and 17.3% in groups A and B, respectively ( P < .0001). Conclusion: Patients undergoing cartilage repair of the tibiofemoral joint with concomitant osteotomy might be expected to experience greater improvement in clinical outcomes with a lower reoperation rate compared with those undergoing cartilage repair alone. Surgeons preparing for cartilage procedures of the knee joint should pay particular attention to preoperative malalignment of the lower extremity to optimize outcomes.

Background: Some studies have suggested that running increases the risk of knee osteoarthritis (OA), while others believe it serves a protective function. Purpose: To perform an updated systematic review of the literature to determine the effects of running on the development of knee OA. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed by searching the PubMed, Cochrane Library, and Embase databases to identify studies evaluating the effect of cumulative running on the development of knee OA or chondral damage based on imaging and/or patient-reported outcomes (PROs). The search terms used were “knee AND osteoarthritis AND (run OR running OR runner).” Patients were evaluated based on plain radiographs, magnetic resonance imaging (MRI), and PROs (presence of knee pain, Health Assessment Questionnaire-Disability Index, and the Knee injury and Osteoarthritis Outcome Score). Results: Seventeen studies (6 level 2 studies, 9 level 3 studies, and 2 level 4 studies), with 7194 runners and 6947 nonrunners, met the inclusion criteria. The mean follow-up time was 55.8 months in the runner group and 99.7 months in the nonrunner group. The mean age was 56.2 years in the runner group and 61.6 years in the nonrunner group. The overall percentage of men was 58.5%. There was a significantly higher prevalence of knee pain in the nonrunner group ( P < .0001). Although 1 study found a significantly higher prevalence of osteophytes in the tibiofemoral (TF) and patellofemoral (PF) joints within the runner group, multiple studies found no significant differences in the prevalence of radiographic knee OA (based on TF/PF joint-space narrowing or Kellgren-Lawrence grade) or cartilage thickness on MRI between runners and nonrunners ( P > .05). One study found a significantly higher risk of knee OA progressing to total knee replacement among nonrunners (4.6% vs 2.6%; P = .014). Conclusion: In the short term, running is not associated with worsening PROs or radiological signs of knee OA and may be protective against generalized knee pain.

Dominant perspectives on technology adoption and consumption tend to be cognitive, instrumental, and individualistic. We offer a desire-centered, future-oriented, and culturally grounded alternative model called the Disenchanted Enchantment Model (DEM). Drawing on historical evidence and revised interpretations of theories of enchantment and disenchantment by Weber and Saler, we show that desire is at the heart of technology consumption’s enchantments, and how its fulfilment is temporary, skeptical, and ironic. We provide an important cultural counterbalance to models such as the Technology Acceptance Model, which replace wonder with reason. Instead we theorize the process that drives contemporary technology adoption as centering on desirous senses of wonderment and anticipation. We offer current and recent examples of the DEM process and discuss the implications this model holds for a new understanding of technology, consumption, desire, and broader consumer culture.

Eravacycline is approved by the U.S. Food and Drug Administration (FDA) for the treatment of complicated intra-abdominal infections. It is a novel, fully synthetic fluorocycline antibiotic belonging to the tetracycline class with a broad-spectrum of activity and an appealing side effect profile. This report describes a 74-year-old female who presented to the hospital with non-ST-elevation myocardial infarction (NSTEMI) requiring coronary artery bypass graft surgery. After surgery, she developed a sternal wound infection that grew multidrug resistant organisms, leading to a much longer than anticipated hospital stay. Eravacycline was eventually added to the antimicrobial regimen for the persistent infection. Shortly after therapy with eravacycline began, the patient started experiencing muscle pain and the creatine phosphokinase (CPK) level was noted to be elevated. Other causes, such as concomitant administration of an HMG-CoA reductase inhibitor, were explored in this case but not thought to be the cause of rhabdomyolysis. The patient’s CPK dropped considerably upon discontinuation of the novel antibiotic, and symptoms resolved. The adverse drug event was reported to the drug manufacturer; however, there are no reports up until this time that address a possible relationship between eravacycline administration and the development of rhabdomyolysis.

Background: Pectoralis major ruptures are rare injuries that occur in young men between 20 and 40 years of age, typically during resistance training in the eccentric phase of muscle contraction. As the incidence of these ruptures increases with increasing activity levels and use of anabolic steroids, it is important to understand effective repair techniques. Indications: Repair of the ruptured pectoralis major tendon is indicated for young, active patients seeking to regain full functionality of the affected upper extremity. Technique Description: In short, after the pectoralis major is identified, the insertion site is revealed just lateral to the biceps tendon. The site for the bone trough is then exposed through cauterization of superficial tissue, and a cortical bone trough is drilled vertically using a small round burr. The location of 3 pilot holes is identified just lateral to the cortical bone trough, and then the holes are drilled to allow for placement of the anchors later in the procedure. The tendon itself is then identified, and sutures are placed in the bulk of the muscle tendon in a Krackow fashion. After the tendon is properly sutured, it is placed under tension to test the structural integrity of the suture pattern and ensure proper load capacity. The sutures are then passed through the pilot holes, the tendon is pulled down into the trough, and the sutures are tied down to the bone. Results: After an appropriate rehabilitation protocol is followed for up to 6 months postoperatively, the transosseous suture technique in the context of pectoralis major tendon repairs allows for adequate tissue to bone healing and near-complete restoration of patient functionality and strength. Conclusion: Acute repair of pectoralis major tendon tears using a transosseous suture technique is effective in restoring upper extremity strength and functionality and is associated with high patient satisfaction. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication. If the individual may be identifiable, the author(s) has included a statement of release or other written form of approval from the patient(s) with this submission for publication.

Background: Latissimus dorsi tendon ruptures are rare injuries that can occur in overhead or throwing motions and are almost always sports related. Indications: Latissimus dorsi tendon ruptures are largely treated nonoperatively, although surgical repair is indicated for the young active patient looking to return to a high level of sport and for those with complete avulsion injuries or mid-substance tendon tears. Technique Description: Depending on the degree of tendon retraction, anteroinferior or posteroinferior axillary incision is made. After the tendon is mobilized, sutures are placed in a Krackow fashion through the bulk of the tendon, and the tendon footprint is prepared by gently decorticating the surface of the humerus, just anterior and inferior to the teres major insertion point. Two Arthrex Pec Buttons are then loaded into the superior and inferior limbs of the suture tape and 2 unicortical holes are drilled into the footprint of the insertion site. The superior button is placed first and then tensioned to allow the latissimus dorsi to be pulled to the bone. Next, the second button is placed, though this is not tensioned until later at the time of the biceps tenodesis. Finally, the procedure is visualized and well inspected to ensure appropriate location of the tendon and securing hardware. Results: After an appropriate rehabilitation protocol is followed for up to 6 months postoperatively, acute repair of a ruptured latissimus dorsi tendon allows for near to complete restoration of patient functionality and strength, with return to full activity possible within 6 to 8 months. Conclusion: Surgical repair of a ruptured latissimus dorsi tendon is effective in restoring upper extremity strength and functionality and is associated with high patient satisfaction. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication. If the individual may be identifiable, the author(s) has included a statement of release or other written form of approval from the patient(s) with this submission for publication.

Background: The use of mesenchymal stem cells (MSCs) for the treatment of knee osteoarthritis (OA) has gained recent interest in the orthopaedics community. Purpose: To review the literature to evaluate the efficacy of umbilical cord–derived MSCs in the treatment of OA of the knee joint. Study Design: Systematic review; Level of evidence, 4. Methods: We searched the PubMed, Cochrane Library, and Embase databases to identify studies with evidence levels from 1 to 4 that evaluated the clinical efficacy of human umbilical cord–derived MSC (hUC-MSC) injections for knee OA. The search phrase used was “umbilical cord knee osteoarthritis.” In the studies reviewed, patients were assessed based on the macroscopic International Cartilage Regeneration & Joint Preservation Society (ICRS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, and the subjective International Knee Documentation Committee (IKDC) score. Results: A total of 7 studies met inclusion criteria, including 385 patients undergoing injection of hUC-MSCs (mean age, 59.7 years). The mean follow-up was 23.4 months. Weighted averages of the WOMAC, macroscopic ICRS, subjective IKDC, and VAS scores all showed improvement from before to after treatment. No severe adverse reactions were recorded. Conclusion: Patients undergoing treatment of knee OA with hUC-MSCs might be expected to experience improvements in clinical outcomes. Additional high-quality randomized studies are needed to better determine the efficacy of hUC-MSC for the treatment of knee OA.

Background: COVID-19 is a severe respiratory virus that spreads via person-to-person contact through respiratory droplets. Since being declared a pandemic in early March 2020, the World Health Organization had yet to release guidelines regarding the return of college or professional sports for the 2020-2021 season. Purpose: To survey the head orthopedic surgeons and primary care team physicians for the National Collegiate Athletic Association (NCAA) Football Bowl Subdivision (FBS) football teams so as to gauge the management of common COVID-19 issues for the fall 2020 college football season. Study Design: Cross-sectional study. Methods: The head team orthopaedic surgeons and primary care physicians for all 130 FBS football teams were surveyed regarding their opinions on the management of college football during the COVID-19 pandemic. A total of 30 questions regarding testing, return-to-play protocol, isolating athletes, and other management issues were posed via email survey sent on June 5, 2020. Results: Of the 210 team physicians surveyed, 103 (49%) completed the questionnaire. Overall, 36.9% of respondents felt that it was unsafe for college athletes to return to playing football during fall 2020. While the majority of football programs (96.1%) were testing athletes for COVID-19 as they returned to campus, only 78.6% of programs required athletes to undergo a mandatory quarantine period before resuming involvement in athletic department activities. Of the programs that were quarantining their players upon return to campus, 20% did so for 1 week, 20% for 2 weeks, and 32.9% quarantined their athletes until they had a negative COVID-19 test. Conclusion: While US Centers for Disease Control and Prevention guidelines evolve and geographic regions experience a range of COVID-19 infections, determining a universal strategy for return to socialization and participation in sports remains a challenge. The current study highlighted areas of consensus and strong agreement, but the results also demonstrated a need for clarity and consistency in operations, leadership, and guidance for medical professionals in multiple areas as they attempt to safely mitigate risk for college football players amid the COVID-19 pandemic.

If digital objects are abundant and ubiquitous, why should consumers pay for, much less collect them? The qualities of digital code present numerous challenges for collecting, yet digital collecting can and does occur. We explore the role of companies in constructing digital consumption objects that encourage and support collecting behaviours, identifying material configuration techniques that materialize these objects as elusive and authentic. Such techniques, we argue, may facilitate those pleasures of collecting otherwise absent in the digital realm. We extend theories of collecting by highlighting the role of objects and the companies that construct them in materializing digital collecting. More broadly, we extend theories of digital materiality by highlighting processes of digital material configuration that occur in the pre-objectification phase of materialization, acknowledging the role of marketing and design in shaping the qualities exhibited by digital consumption objects and, consequently, related consumption behaviours and experiences.

This study investigates the shifting discourse and visual rhetoric of consumer rituals in the cultural media during wartime. Specifically, we examine Japanese newspaper advertisements for seasonal gifts and sympathy gifts in urban cities published between 1937 and 1940. This research addresses two questions: (1) how were advertising arguments constructed justifying spending for gifts while instructing readers on being thrifty during the wartime material shortages, and (2) how was the consumer ritual practice of gift giving used to propagate nationalism? The results of our iconographic-semiotic analysis show four advertising themes: compatibility with national policy, timeliness under the wartime circumstances, empathy with families whose members were serving at the front, and sympathy with those serving at the front. The advertisements enhanced nationalism in two ways: (1) through the promotion of nationalistic gift giving, and (2) by appealing to patriotism, which involves emotionally laden nationalistic sentiments.

Incorporating Illouz’s theory of emotions, this study examines how specific emotions drive consumption, as embodied by escalating conflicts between Hong Kong and the PRC luxury consumers. When affluent Mainlanders pursue status signifiers via consumption of relatively affordable luxury goods in Hong Kong, local residents’ disdain triggers a nexus of emotions: envy, resentment, and status anxiety, linked to fears of being occupied by and assimilated into Chinese culture. Deploying cultural capital and status competition rooted in imagination and refinement, Hong Kongese contrast their knowledge-based use of luxury brands with the avid consumption of PRC visitors, fueled by often extreme wealth. For Hong Kongese, such one-upmanship degenerates into self-doubt and self-failure in their image management attempts, precipitating intense hostility toward PRC consumers. Emotions engender colliding notions of self, status, and cultural and political identity between these disparate yet intertwined cultures.

The most efficacious psychosocial intervention for reducing attention-deficit/hyperactivity disorder (ADHD) symptoms in young children is behavioral parent training (BPT). Potential benefits are hindered by limited accessibility, low session attendance, and poor implementation of prescribed strategies. As a result, only approximately half of families with young children with ADHD receive BPT. We describe an innovative approach for reducing barriers to BPT access. Specifically, we invoked an iterative, 5-step process of intervention development and revision to modify an existing face-to-face BPT program and develop an online version. Results indicated that the revised program and online versions (a) increased parent engagement with BPT, (b) enhanced accessibility, (c) produced favorable parent acceptability and feasibility ratings, and (d) resulted in improved child outcomes.

Background: Patients with recurrent lateral patellar dislocations are often treated with reconstruction of the medial patellofemoral ligament (MPFL). Purpose: To perform a systematic review to evaluate clinical outcomes and the risk of recurrent patellar dislocation after MPFL reconstruction (MPFLR) with autograft versus allograft. Study Design: Systematic review; Level of evidence, 4. Methods: The authors conducted a search of PubMed, the Cochrane Library, and Embase to identify studies comparing outcomes of MPFLR with autograft versus allograft. The inclusion criteria were full-text studies that directly compared clinical outcomes and/or risk of recurrent patellar instability between patients undergoing MPFLR with autograft versus allograft. A quality assessment was performed using the modified Coleman Methodology Score, and risk-of-bias assessment was performed using the Risk Of Bias In Non-randomized Studies–of Interventions and the Cochrane Collaboration tools. Results: Seven studies (1 evidence level 2, 3 level 3, 3 level 4) that met inclusion criteria were identified and included a total of 150 patients who underwent MPFLR with autograft and 193 with MPFLR with allograft. One study found a significantly higher failure rate among patients with autograft, and another study found a trend toward a significantly higher failure rate among patients with autograft. One study demonstrated no significant difference between postoperative tibial tubercle–trochlear groove distance (measured on magnetic resonance imaging scans) in failed versus successful grafts. One study found that patellar tilt angle improved significantly from preoperatively to postoperatively ( P < .001) but there was no difference between the groups. Kujala scores significantly improved for both autograft and allograft groups across studies. Two studies found significant differences in postoperative Kujala scores between the 2 groups, 1 of which found better scores in the allograft group ( P = .0032) and another in which scores were better in the autograft group ( P = .02). Conclusion: Patients undergoing MPFLR with either autograft or allograft can expect to experience improvement in clinical outcomes. Subjective outcomes improved to a similar degree in both groups. Graft failure was more frequently observed in patients with autograft. Allograft may be a better option for MPFLR owing to lower failure rate.

Background: Recent evidence suggests that there may be an increased risk of infection for patients undergoing a corticosteroid injection before, during, or after knee arthroscopy. Purpose: To systematically review the literature to evaluate the risk of postoperative infection in patients undergoing intra-articular corticosteroid injections (CSI) before, during, or after knee arthroscopy. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic review was performed by searching the PubMed, Cochrane Library, and Embase databases to identify studies that evaluated the rate of postoperative infection in patients undergoing knee arthroscopy who received an intra-articular CSI during the perioperative period. The search phrase used was “knee AND arthroscopy AND injection AND (infection OR revision).” A subanalysis was also performed to analyze infection rates based on the timing of the corticosteroid injection in relation to arthroscopy. Results: Four studies met the inclusion criteria, representing 11,925 patients undergoing knee arthroscopy with an intra-articular CSI administered during the perioperative period (mean follow-up, 5.3 months) and 247,329 patients without a corticosteroid injection during the perioperative period (mean follow-up, 5.9 months). Patients who received an injection experienced a statistically significantly higher rate of postoperative infection (2.2%) when compared with patients who did not receive an injection (1.1%; P < .001). When analyzed by the timing of the injection, patients receiving an injection preoperatively or intraoperatively experienced a statistically significantly higher rate of postoperative infection (3% and 2.6%, respectively) when compared with patients receiving an injection postoperatively (1.4%; P = .001 for both). Conclusion: Patients undergoing knee arthroscopy who receive an intra-articular CSI during the perioperative period can be expected to experience significantly higher postoperative infection rates when compared with patients not receiving an injection. Furthermore, patients receiving a corticosteroid injection pre- or intraoperatively may experience significantly higher rates of postoperative infection when compared with patients receiving an injection postoperatively.

Introduction: Historically, perioperative hemoglobin monitoring has relied on calculated saturation, using blood gas devices that measure plasma hematocrit (Hct). Co-oximetry, which measures total hemoglobin (tHb), yields a more comprehensive assessment of hemodilution. The purpose of this study was to examine the association of tHb measurement by co-oximetry and Hct, using conductivity with red blood cell (RBC) transfusion, length of stay (LOS) and inpatient costs in patients having major cardiac surgery. Methods: A retrospective study was conducted on patients who underwent coronary artery bypass graft (CABG) and/or valve replacement (VR) procedures from January 2014 to June 2016, using MedAssets discharge data. The patient population was sub-divided by the measurement modality (tHb and Hct), using detailed billing records and Current Procedural Terminology coding. Cost was calculated using hospital-specific cost-to-charge ratios. Multivariable logistic regression was performed to identify significant drivers of RBC transfusion and resource utilization. Results: The study population included 18,169 cardiovascular surgery patients. Hct-monitored patients accounted for 66% of the population and were more likely to have dual CABG and VR procedures (10.4% vs 8.9%, p=0.0069). After controlling for patient and hospital characteristics, as well as patient comorbidities, Hct-monitored patients had significantly higher RBC transfusion risk (OR=1.26, CI 1.15-1.38, pConclusions: tHb monitoring during cardiovascular surgery could offer a significant reduction in RBC transfusion, length of stay and hospital cost compared to Hct monitoring.

Background:Multiple studies have demonstrated a higher risk of graft failure after anterior cruciate ligament reconstruction with allograft, but limited data are available comparing outcomes of posterior cruciate ligament reconstruction (PCLR) with autograft versus allograft.Purpose:To compare the clinical outcomes of autograft versus allograft for primary PCLR.Study Design:Systematic review.Methods:A systematic review was performed by searching PubMed, the Cochrane Library, and EMBASE to locate studies (level of evidence I-III) comparing clinical outcomes of autograft versus allograft in patients undergoing primary PCLR with the conventional transtibial technique. Search terms used were “posterior cruciate ligament,” “autograft,” and “allograft.” Patients were evaluated based on graft failure rate, examination of knee laxity, and patient-reported outcome scores (Lysholm, Tegner, subjective International Knee Documentation Committee [IKDC], and objective IKDC scores).Results:Five studies (2 level II, 3 level III) were identified that met inclusion criteria, including a total of 132 patients undergoing PCLR with autograft (semitendinosus-gracilis or bone–patellar tendon–bone) and 110 patients with allograft (tibialis anterior, Achilles tendon, or bone–patellar tendon–bone). No patients experienced graft failure. Average anteroposterior (AP) knee laxity was significantly higher in allograft patients (3.8 mm) compared with autograft patients (3.1 mm) ( P < .01). Subjective IKDC, Lysholm, and Tegner scores improved for both groups across studies, without a significant difference in improvement between groups except in one study, in which Lysholm scores improved to a significantly greater extent in the autograft group ( P < .01).Conclusion:Patients undergoing primary PCLR with either autograft or allograft can be expected to experience improvement in clinical outcomes. Autograft patients experienced less AP knee laxity postoperatively, although the clinical significance of this is unclear and subjective outcomes improved substantially and to a similar degree in both groups.
