Abstract
BACKGROUND Inflammatory arthritis (IA) represents a less common indication for anatomic and reverse total shoulder arthroplasty (TSA) than osteoarthritis (OA). The safety and efficacy of anatomic and reverse TSA in this population has not been as well studied compared to OA. We analyzed the differences in outcomes between IA and OA patients undergoing TSA. METHODS Patients who underwent primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) from 2016-2020 were identified in the Premier Healthcare Database. Inflammatory arthritis (IA) patients were identified using International Classification of Diseases, Tenth Revision, diagnosis codes and compared to osteoarthritis controls. Patients were matched in a 1:8 fashion by age (±3 years), sex, race, and presence of pertinent comorbidities. Patient demographics, hospital factors, and patient comorbidities were compared. Multivariate regression was performed following matching to account for any residual confounding and 90-day complications were compared between the 2 cohorts. Descriptive statistics and regression analysis were employed with significance set at P < .05. RESULTS Prior to matching, 5685 IA cases and 93,539 OA controls were identified. Patients with IA were more likely to be female, have prolonged length of stay and increased total costs (P < .0001). After matching and multivariate analysis, 4082 IA cases and 32,656 controls remained. IA patients were at increased risk of deep wound infection (OR 3.14, 95% CI 1.38-7.16, P = .006), implant loosening (OR 4.11, 95% CI 1.17-14.40, P = .027), and mechanical complications (OR 6.34, 95% CI 1.05-38.20, P = .044), as well as a decreased risk of postoperative stiffness (OR 0.36, 95% CI 0.16-0.83, P = .002). Medically, IA patients were at increased risk of PE (OR 2.97, 95% CI 1.52-5.77, P = .001) and acute blood loss anemia (OR 1.27, 95% CI 1.12-1.44, P < .0001). DISCUSSION AND CONCLUSION Inflammatory arthritis represents a distinctly morbid risk profile compared to osteoarthritis patients with multiple increased surgical and postoperative medical complications in patients undergoing aTSA and rTSA. Surgeons should consider these potential complications and employ a multidisciplinary approach in preoperative risk stratification of IA undergoing shoulder replacement.

Abstract
When delivering cells on a scaffold to treat a bone defect, the cell seeding technique determines the number and distribution of cells within a scaffold, however the optimal technique has not been established. This study investigated if human adipose-derived stem cells (ASCs) transduced with a lentiviral vector to overexpress bone morphogenetic protein 2 (BMP-2) and loaded on a scaffold using dynamic orbital shaker could reduce the total cell dose required to heal a critical sized bone defect when compared with static seeding. Human ASCs were loaded onto a collagen/biphasic ceramic scaffold using static loading and dynamic orbital shaker techniques, compared with our labs standard loading technique, and implanted into femoral defects of nude rats. Both a low dose and standard dose of transduced cells were evaluated. Outcomes investigated included BMP-2 production, radiographic healing, micro-computerized tomography, histologic assessment, and biomechanical torsional testing. BMP-2 production was higher in the orbital shaker cohort compared with the static seeding cohort. No statistically significant differences were noted in radiographic, histomorphometric, and biomechanical outcomes between the low-dose static and dynamic seeding groups, however the standard-dose static seeding cohort had superior biomechanical properties. The standard-dose 5 million cell dose standard loading cohort had superior maximum torque and torsional stiffness on biomechanical testing. The use of orbital shaker technique was labor intensive and did not provide equivalent biomechanical results with the use of fewer cells.

Abstract
BACKGROUND Perioperative intravenous (IV) dexamethasone is commonly used in lower extremity total joint arthroplasty to manage postoperative pain and nausea/vomiting, and recent studies have demonstrated that its use may lower rates of acute postoperative medical complications. However, there is limited information regarding the safety and efficacy of IV dexamethasone in patients undergoing total shoulder arthroplasty (TSA). Additionally, there is concern surrounding corticosteroid use prior to surgery as preoperative corticosteroid injections have been associated with adverse outcomes after TSA, including periprosthetic joint infection (PJI) and revision surgery. Thus, the purpose of this study was to evaluate the effect of perioperative IV dexamethasone on 90-day rates of PJI, wound complications, and medical complications after TSA. METHODS The Premiere national hospital database was used to identify adult patients undergoing elective TSA between 2016 and 2020; patients were excluded if they were under 18 years old, were undergoing revision TSA, or had a prior proximal humerus open reduction internal fixation (ORIF) procedure. Patients who did and did not receive perioperative IV dexamethasone were then compared in both univariate and multivariate analyses. A Bonferroni correction was utilized to adjust for multiple comparisons. The primary endpoint was risk of acute infectious complications within 90 days of surgery, including PJI and wound infection/dehiscence. Secondary endpoints included acute pulmonary, renal, and thromboembolic complications. RESULTS A total of 135,333 patients underwent TSA during the study period; 61.2% underwent reverse total shoulder arthroplasty (RTSA), 33.8% underwent anatomic total shoulder arthroplasty (ATSA), and 5.0% underwent hemiarthroplasty (HA). From 2016 to 2020, perioperative IV dexamethasone use increased by 135%. Multivariate analysis revealed that patients who received perioperative IV dexamethasone did not have increased odds of PJI, superficial wound infection, or wound dehiscence (p = 0.15 - 0.47) but did have decreased odds of sepsis (OR 0.67, 95% CI 0.55-0.81) and other medical complications such as urinary tract infection (UTI) and acute kidney injury (AKI). Additionally, there was a trend towards decreased 90-day hospital readmission (OR 0.88, 95% CI 0.81-0.96, p=0.003). CONCLUSIONS Perioperative IV dexamethasone was not associated with increased risk of acute infectious and wound healing complications. Moreover, patients who received perioperative IV dexamethasone had decreased odds of medical complications and trended towards lower rates of 90-day hospital readmission. The results of this study support the safety of perioperative IV dexamethasone use in patients undergoing elective TSA.

Abstract
Purpose To determine the rate of reporting for sociodemographic variables in randomized controlled trials (RCTs) investigating femoral acetabular impingement (FAI) and hip arthroscopy. Methods PubMed, Scopus, and Web of Science were queried for articles relating to FAI and hip arthroscopy. Articles included in final analysis were RCTs investigating operative management of FAI. Included RCTs were analyzed for reporting of age and sex or gender as well as the following sociodemographic variables: race, ethnicity, insurance status, income, housing status, work status, and education level in the results section or any section of the paper. Data was analyzed using χ2 and Fisher exact tests with significance defined as P < .05. Results Forty-eight RCTs were identified from 2011 to 2023. Age was reported in 48 of 48 (100%) of included papers; sex or gender was reported in 47 of 48 (97.9%). Reporting of sociodemographic variables in any section respectively was: race (7/48, 14.6%), ethnicity (4/48, 8.33%), insurance status (0/48, 0%), income (1/48, 2.08%), housing status (0/48, 0%), work status (3/48, 6.25%), and education (2/48, 4.17%). There was no significant difference for reporting demographic variables with respect to journal or year of publication (P = .666 and P = .761, respectively). Sociodemographic variables (9/48) were reported significantly less frequently than age and sex or gender (48/48) (P < .001). Conclusions This study found that sociodemographic variables in FAI and hip arthroscopy RCTs are reported with much lower frequency than age and sex or gender. These findings may demonstrate the need to include patient sociodemographic data in RCTs so that their results can be better generalized and applied to the appropriate patient population. Level of Evidence Level II, systematic review of level I and II evidence.

Abstract
BACKGROUND Same-day total hip arthroplasty (THA) and total knee arthroplasty (TKA) continue to gain popularity in the United States. The present study sought to quantify recent same-day outpatient trends taking into consideration the COVID-19 pandemic as well as the removal of these procedures from the Medicare inpatient only (IPO) list. METHODS Patients undergoing primary elective TKA and THA were identified using the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample from January 1, 2016, to December 31, 2020. The same-day cohort included Nationwide Ambulatory Surgery Sample and National Inpatient Sample patients with a length of stay = 0 days. The inpatient cohort included patients with length of stay ≥1 day. National estimates were extrapolated using weight functions. RESULTS From January 2016 to December 2020, the proportion of same-day TKA increased from 1.2 (719) to 62.4% (31,293) and the proportion of same-day THA increased from 2.0 (599) to 54.5% (18,252). Following removal from the Medicare IPO list, same-day TKAs increased from 3.2% (1,895) in December 2017 to 13.8% (9,269) in January 2018, and same-day THAs increased from 10.7% (4,295) in December 2019 to 22.5% (8,708) in January 2020. Between February and March 2020, same-day TKAs increased from 42.4 (26,148) to 44.4% (16,972) and same-day THAs increased from 28.5 (10,729) to 30.2% (7,409). CONCLUSIONS The proportion of same-day TKA and THA dramatically increased following removal from the Medicare IPO list and in response to the COVID-19 pandemic. By December 2020, same-day TKA and THA accounted for >50% of all cases performed in the United States.

Abstract
Background Inpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA) practices were dramatically affected in the United States in 2020 as elective surgeries were paused in response to the COVID-19 pandemic. This study sought to provide an updated estimate of inpatient total joint arthroplasty (TJA) case volumes in the United States in 2020. Methods A retrospective cohort study was performed by identifying all adult patients who underwent primary, elective TJA from January 1st, 2017 to December 31st, 2020, using the National Inpatient Sample. Monthly and annual case volumes were reported with descriptive statistics. Baseline case volumes were established by taking the average number of monthly cases performed in 2017, 2018, and 2019. These monthly averages were compared to 2020 values. Results From 2017 to 2019, the average case volume was 1,056,669 cases per year (41.0% THA, 59.0% TKA) and 88,055 cases per month. In 2020, 535,441 cases were identified (45.4% THA, 54.6% TKA), corresponding to a 49.3% reduction from the 2017-2019 annual average. Monthly cases decreased to 4515 in April during the "first wave" of COVID-19, corresponding to a 94.8% decrease from prior years. In June, cases rebounded to 55,520 before decreasing again in July to 50,100 during the "second wave" of COVID-19. During the "third wave," COVID-19 cases decreased month-over-month from October through December (56.5% decrease). Conclusions This updated estimate identified a 49.3% decrease in inpatient TJA cases in 2020 compared to prior years. This is similar to the 46.5-47.7% decrease in case volume previously reported.

Abstract
CONTEXT While current literature has explored the outcomes of athletes who return to sport (RTS) after anterior cruciate ligament (ACL) injuries, less is known about the outcomes of those who are unsuccessful in returning to sport. OBJECTIVE To determine the rate of athletes who did not RTS after primary ACL reconstruction (ACLR) and to identify the specific subjective reasons for failure to RTS. DATA SOURCES A comprehensive search of the PubMed/MEDLINE, Scopus, and Web of Science databases was conducted through April 2021. STUDY SELECTION Eligible studies included those explicitly reporting the rate of failure for RTS after ACLR as well as providing details on reasons for athletes' inability to return; 31 studies met the inclusion criteria. STUDY DESIGN Systematic review and meta-analysis. LEVEL OF EVIDENCE Level 2 to 4. DATA EXTRACTION The reasons for failure to RTS referred to in our study are derived from those established previously in the studies included. Data were collected on the number of athletes, mean age, mean follow-up time, type of sport played, failure to RTS rate, and specific reasons for failure to return. RESULTS The weighted rate of failure to RTS after ACLR was 25.5% (95% CI, 19.88-31.66). The estimated proportion of psychosocial-related reasons cited for failure to RTS was significantly greater than knee-related reasons for failure RTS (55.4% vs 44.6%, P < 0.01). The most cited reason for failure to RTS was fear of reinjury (33.0%). CONCLUSION This study estimates the rate of failure to RTS after ACLR to be 25.5%, with the majority of athletes citing fear of reinjury as the major deterrent for returning to sports. We highlight how factors independent of surgical outcomes may impact an athlete's ability to return to play given that the predominant reason for no RTS after ACLR was unrelated to the knee.

Abstract
BACKGROUND Glenohumeral osteoarthritis is one of the most common causes of shoulder pain. As such, the American Academy of Orthopaedic Surgeons (AAOS) has developed clinical practice guidelines (CPGs) to address the management of glenohumeral osteoarthritis. These CPG recommendations stem from the findings of randomized controlled trials (RCTs), which have been shown to influence clinical decision making and health policy. Therefore, it is essential that trial outcomes, including harms data (ie, adverse events), are adequately reported. We intend to evaluate the reporting quality of harms-related data in orthopedic literature specifically relating to AAOS CPG recommendations on the management of glenohumeral osteoarthritis. METHODS We adhered to the Preferred Reporting Items for Systematic Reviews (PRISMA) as well as guidance for reporting meta-research. The AAOS CPGs for glenohumeral osteoarthritis were obtained from orthoguidelines.org, and 2 authors independently screened the guidelines for the RCTs referenced. A total of 14 studies were identified. Data were extracted from the 14 included studies independently by the same 2 authors. Adherence to the Consolidated Standards of Reporting Trials (CONSORT) Extension for Harms Checklist was assessed using an 18-item scoring chart, with 1 point being awarded for meeting a checklist item and 0 points being awarded for not meeting a checklist item. Descriptive statistics, such as frequencies, percentages, and 95% confidence intervals were used to summarize RCT adherence to the CONSORT checklist. RESULTS The average score among the studies included was 7.36/18 items (39% adherence). No study adhered to all criteria, with the highest-performing study meeting 11 of 18 items (58%) and the lowest meeting 3 of 18 items (16%). A positive correlation between checklist score and year of publication was observed, with studies published more recently receiving a higher score on the CONSORT checklist (P < .05). Studies that disclosed funding information received a higher score than those that did not (P < .05), but there was no significant difference when the different funding sources were compared. Finally, double-blinded studies scored higher on the checklist than those with lower levels of blinding (single or no blinding, P < .05). CONCLUSION Adverse events are poorly reported amongst RCTs cited as supporting evidence for AAOS Management of Glenohumeral Osteoarthritis CPGs, evidenced by a CONSORT checklist compliance rate of only 41% in this study. We recommend the development of an updated checklist with information that makes it easier for authors to recognize, evaluate, and report on harms data. Additionally, we encourage authors to include information about adverse events or negative outcomes in the abstract.

Abstract
Advances in artificial intelligence and machine learning models, like Chat Generative Pre-trained Transformer (ChatGPT), have occurred at a remarkably fast rate. OpenAI released its newest model of ChatGPT, GPT-4, in March 2023. It offers a wide range of medical applications. The model has demonstrated notable proficiency on many medical board examinations. This study sought to assess GPT-4's performance on the Orthopaedic In-Training Examination (OITE) used to prepare residents for the American Board of Orthopaedic Surgery (ABOS) Part I Examination. The data gathered from GPT-4's performance were additionally compared with the data of the previous iteration of ChatGPT, GPT-3.5, which was released 4 months before GPT-4. GPT-4 correctly answered 251 of the 396 attempted questions (63.4%), whereas GPT-3.5 correctly answered 46.3% of 410 attempted questions. GPT-4 was significantly more accurate than GPT-3.5 on orthopedic board-style questions (P<.00001). GPT-4's performance is most comparable to that of an average third-year orthopedic surgery resident, while GPT-3.5 performed below an average orthopedic intern. GPT-4's overall accuracy was just below the approximate threshold that indicates a likely pass on the ABOS Part I Examination. Our results demonstrate significant improvements in OpenAI's newest model, GPT-4. Future studies should assess potential clinical applications as AI models continue to be trained on larger data sets and offer more capabilities. [Orthopedics. 2024;47(2):e85-e89.].

Abstract
STUDY DESIGN Systematic review. OBJECTIVES Spin in scientific literature is defined as bias that overstates efficacy and/or underestimates harms of procedures undergoing review. While lumbar microdiscectomies (MD) are considered the gold standard for treating lumbar disc herniations (LDH), outcomes of novel procedures are being weighed against open MD. This study identifies the quantity and type of spin in systematic reviews and meta-analyses of LDH interventions. METHODS A search was conducted on the PubMed, Scopus, and SPORTDiscus databases for systematic reviews and meta-analyses evaluating the outcomes of MD against other LDH interventions. Each included study's abstract was assessed for the presence of the 15 most common types of spin, with full texts reviewed during cases of disagreement or for clarification. Full texts were used in the assessment of study quality per AMSTAR 2. RESULTS All 34 included studies were observed to have at least 1 form of spin, in either the abstract or full text. The most common type of spin identified was type 5 ("The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies"), which was observed in ten studies (10/34, 29.4%). There was a statistically significant association between studies not registered with PROSPERO and the failure to satisfy AMSTAR type 2 (P < .0001). CONCLUSION Misleading reporting is the most common category of spin in literature related to LDH. Spin overwhelmingly tends to go in the positive direction, with results inappropriately favoring the efficacy or safety of an experimental intervention.

Abstract
BACKGROUND It is well known that socioeconomic and demographic variables can greatly affect health outcomes. Previous studies across medical and surgical subspecialties have demonstrated that these variables are frequently under-reported in randomized controlled trials (RCTs). No such study currently exists that examines rates of reporting sociodemographic variables in shoulder arthroplasty RCTs. This study aims to present these rates and explore the impacting of failing to report socioeconomic variables in shoulder arthroplasty RCTs. METHODS The PubMed database was queried for the term "shoulder arthroplasty." 65 RCTs from the last ten years were identified for inclusion from five high-impact orthopedic surgery journals. Each RCT was analyzed for patient age and sex or gender as well as the following sociodemographic variables: race, ethnicity, insurance status, income, work status, and education. It was also noted whether each above variable was mentioned in the results section of the paper. Data was presented in a descriptive fashion as well as analyzed using Chi-squared and Fisher's exact test where appropriate. RESULTS From 2014-2023, 65 shoulder arthroplasty RCTs published reported age in 40/65 (61.5%) of results sections and 61/65 (93.8%) of any section. Sex or gender were reported in 27/65 (41.5%) of results sections and 61/65 (93.8%) of any section. No manuscripts included any sociodemographic variables in the results section. Reporting rates for sociodemographic variables in any section were: race 6/65 (9.2%), ethnicity 5/65 (7.7%), work status 4/65 (6.2%), and insurance status 1/65 (1.5%). No studies included income or education of the enrolled patients. There was no difference in reporting sociodemographic variables by journal (p = 0.45) or by year of publication (p = 0.57). However, no study prior to 2020 included any sociodemographic variable (0/27, 0%) whereas from 2020 onward six studies included at least one (6/38, 15.8%). Sociodemographic variables were reported significantly less frequently than age and sex or gender (p = 0.001). DISCUSSION Our study found sociodemographic variables are rarely reported in shoulder arthroplasty RCTs, whereas age and sex or gender are reported with great frequency. In order to understand the results of shoulder arthroplasty RCTs, apply their findings to the care of our patients and address health disparities we must ensure these studies include patient sociodemographic data.

Abstract
Purpose To compare the patient-reported outcomes between patients with posterior cruciate ligament (PCL) reconstruction or repair alone versus PCL reconstruction or repair with internal bracing (IB) in the context of multi-ligament knee injuries (MLKI). Methods All patients who underwent surgical management of MLKI at two institutions between 2006 and 2020 were retrospectively identified and offered participation in the study. Patient reported outcomes were measured via three instruments: Lysholm Knee score, Multiligament Quality of Life (ML-QOL), and the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive testing (CAT). The postoperative outcomes and reoperation rates were compared between the internal bracing and non-internal bracing groups. Results Fifty-two patients were analyzed; 34 were included in the IB group (17.6% female; age 33.1 ±1.60 years), and 18 were included in the non-IB group (11.1% female; age 34.1 ±3.72 years). Mean follow-up time of the entire cohort was 1.44 ± 0.22 years (IB: 1.21 ± 0.18; non-IB: 2.1 ±0.65). There were no significant differences between PROMIS CAT [PROMIS Pain (54.4 ±1.78 vs 51.7 ±1.70, p=0.319), Physical Function (44.3 ±2.27 vs 47.9 ±1.52, p=0.294), Mobility (44.0 ±1.71 vs 46.1 ±2.10, p=0.463)], ML-QOL [ML-QOL Physical Impairment (40.7 ±4.21 vs 41.7±5.10, p=0.884), Emotional Impairment (49.2 ±4.88 vs 44.7±5.87, p=0.579), Activity Limitation (43.5 ±4.56 vs 31.5±3.62, p=0.087), Societal Involvement (44.9 ±4.96 vs 37.5 ±5.30, p=0.345)] and Lysholm knee score (61.8 ±4.55 vs 61.0 ±4.95, p=0.916) postoperatively compared to the non-IB group. Conclusion In this group of patients, function and patient-reported outcomes between patients treated with PCL reconstruction and repair without internal brace versus those with additional internal brace augmentation were not significantly different. Further research encompassing a larger patient sample is necessary to investigate the efficacy of the internal brace for PCL injury in the context of MLKI injuries.

Abstract
Purpose To describe the incidence and types of spin in systematic reviews of platelet-rich plasma (PRP) injections for hip osteoarthritis (OA) and to determine whether patterns in study characteristics could be identified among studies with identifiable spin. Methods The PubMed, Scopus, and SPORTDiscus databases were queried. Inclusion criteria were systematic reviews or meta-analyses that included an assessment of intra-articular PRP injections as a stand-alone treatment for hip OA. Two authors independently assessed the presence of spin in the included studies and recorded general study characteristics. The prevalence of the 15 different categories of spin was quantified using descriptive statistics. Results Fifteen studies met inclusion criteria for this study. All studies contained at least two types of spin (range 2-9), with a median of 2. The most common type of spin was type 14 ("Failure to report a wide confidence interval of estimates"), which was observed in 10 studies. The second most common type of spin was type 13 ("Failure to specify the direction of the effect when it favors the control intervention"), found in 6 studies. Conclusions Spin is highly prevalent in abstracts of systematic reviews of PRP in the treatment of hip OA. Several associations were found between spin types and the study characteristics of AMSTAR 2 rating, Scopus CiteScore, journal impact factor, and PROSPERO preregistration. When present, spin in the abstracts of reviewed studies tended to favor the use of PRP in hip osteoarthritis. Clinical Relevance It is important to understand the prevalence of spin in published abstracts, especially in areas of great impact or interest, so authors and readers can have a greater awareness of this potential form of bias.

Abstract
BACKGROUND Inpatient total hip and total knee arthroplasty were substantially impacted by the SARS-CoV-2 (COVID-19) pandemic. We sought to characterize the transition of total joint arthroplasty (TJA) to the outpatient setting in 2 large state health systems during this pandemic. METHODS Adult patients who underwent primary elective TJA between January 1, 2016 and December 31, 2020 were retrospectively reviewed using the New York Statewide Planning and Research Cooperative System and California Department of Health Care Access and Information datasets. Yearly inpatient and outpatient case volumes and patient demographics, including age, sex, race, and payer coverage, were recorded. Continuous and categorical variables were compared using descriptive statistics. Significance was set at P < .05. RESULTS In New York during 2020, TJA volume decreased 16% because 22,742 fewer inpatient TJAs were performed. Much of this lost volume (46.6%) was offset by a 166% increase in outpatient TJA. In California during 2020, TJA volume decreased 20% because 34,114 fewer inpatient TJAs were performed. Much of this lost volume (37%) was offset by a 47% increase in outpatient TJA. CONCLUSIONS This present study demonstrates a marked increase in the proportion of TJA being performed on an outpatient basis in both California and New York. In both states, despite a decrease in overall TJA volume in 2020, outpatient TJA volume increased markedly. LEVEL OF EVIDENCE Therapeutic Level IV, Retrospective Cohort Study.

Abstract
BACKGROUND Tranexamic acid (TXA) is increasingly utilized during total knee arthroplasty (TKA) and total hip arthroplasty (THA) to decrease blood loss; however, there are concerns with regard to potential thromboembolic complications, particularly in high-risk patients. This study sought to define a subset of patients at elevated risk for thromboembolic complications following total joint arthroplasty (TJA) and to compare postoperative outcomes between patients who received TXA and those who did not. METHODS Patients who underwent primary, elective TJA from 2015 to 2021 were identified in the Premier Healthcare Database. Patients with a history of venous thromboembolism, defined as a history of pulmonary embolism or deep vein thrombosis, were identified and formed the high-risk cohort. Patient demographic characteristics, hospital factors, patient comorbidities, antithrombotic medication use, perioperative blood transfusion, and 90-day complications were assessed and compared between patients who received TXA and those who did not. Univariate regression and multivariable regression were performed to account for potential confounders. RESULTS The high-risk cohort comprised 70,759 patients who underwent TJA, of whom 46,074 (65.1%) received TXA and 24,685 (34.9%) did not. After controlling for confounding factors, patients in the TXA cohort had similar risks of pulmonary embolism (adjusted odds ratio [OR], 0.90 [95% confidence interval (CI), 0.79 to 1.02]; p = 0.097), stroke (adjusted OR, 0.97 [95% CI, 0.69 to 1.37]; p = 0.867), and myocardial infarction (adjusted OR, 0.93 [95% CI, 0.69 to 1.24]; p = 0.614) compared with patients who did not receive TXA. Patients who received TXA demonstrated decreased risks of transfusion (adjusted OR, 0.42 [95% CI, 0.38 to 0.46]; p < 0.001) and 90-day readmission (adjusted OR, 0.87 [95% CI, 0.80 to 0.94]; p < 0.001). CONCLUSIONS TXA utilization was not associated with an increased risk of postoperative pulmonary embolism, stroke, or myocardial infarction in patients with a history of venous thromboembolism. Furthermore, patients who received TXA had a decreased risk of transfusion and readmission. This evidence suggests that TXA may be safely utilized among select high-risk patients.

Abstract
PURPOSE To analyze reporting bias in the form of spin present in systematic reviews and meta-analyses on the topic of primary anterior cruciate ligament (ACL) repair. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed throughout this study. Peer-reviewed systematic reviews were collected from 3 databases (PubMed, Scopus, and SPORTDiscus), and their abstracts were assessed for the 15 most common types of spin. Articles were excluded if they were not published in English, had no evidence, were retracted, were published without an abstract, did not have full text available, or included cadaveric or nonhuman subjects. Full text quality was assessed using AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews Version 2). Fisher exact tests were used to examine associations between the different types of spin and other study characteristics such as AMSTAR 2 confidence rating, study design, and level of evidence. RESULTS Spin was present in the abstracts of 13 of 15 articles (86.7%). There were significant associations between PRISMA adherence and lower incidences of spin types 3, 6, and 8 (P = .029 for each). A critically low AMSTAR 2 confidence rating was significantly associated with an increased incidence of spin type 9 (P = .01), and a higher AMSTAR 2 score was significantly associated with decreased spin type 4 and type 5 (P = .039 and P = .048, respectively). A more recent year of publication was correlated with a lower incidence of spin type 14 (P = .044). CONCLUSIONS Spin is present in most systematic reviews and meta-analyses regarding primary repair of the ACL, with two-thirds of abstracts spinning evidence in favor of ACL repair. Standardized guidelines including the PRISMA guidelines and the AMSTAR 2 assessment tool were negatively correlated with spin. More recently published articles were found to contain significantly less spin, as were articles published in journals with higher Clarivate Impact Factors and Scopus CiteScores.

Abstract
HYPOTHESIS Clinical studies are often at risk of spin, a form of bias where beneficial claims are overstated while negative findings are minimized or dismissed. Spin is often more problematic in abstracts given their brevity and can result in the misrepresentation of a study's actual findings. The goal of this study is to aggregate primary and secondary studies reporting the clinical outcomes of the use of subacromial balloon spacers in the treatment of massive irreparable rotator cuff tears to identify the incidence of spin and find any significant association with study design parameters. MATERIALS AND METHODS This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Independent searches were completed on 2 databases (PubMed and Embase) for primary studies, systematic and current concepts reviews, and meta-analyses and the results were compiled. Two authors independently screened the studies using a predetermined inclusion criteria and aggregated data including titles, publication journals and years, authors, study design, etc. Each study was independently assessed for the presence of 15 different types of spin. Statistical analysis was conducted to identify associations between study characteristics and spin. RESULTS Twenty-nine studies met the inclusion criteria for our analysis, of which 10 were reviews or meta-analyses and 19 were primary studies. Spin was identified in every study except for 2 (27/29, 93.1%). Type 3 spin, "Selective reporting of or overemphasis on efficacy outcomes or analysis favoring the beneficial effect of the experimental intervention" and type 9 spin, "Conclusion claims the beneficial effect of the experimental treatment despite reporting bias" were most frequently noted in our study, both observed in 12/29 studies (41.4%). Date of publication, and adherence to Preferred Reporting Items for Systematic Reviews and Meta-Analyses or "The International Prospective Register of Systematic Reviews" were study characteristics associated with a higher rate of certain types of spin. There was a statistically significant association between disclosure of external study funding source and the presence of spin type 4, but none of the other forms of spin. CONCLUSION Spin is highly prevalent in the abstracts of primary studies, systematic reviews, and meta-analyses discussing the use of subacromial balloon spacer technology in the treatment of massive irreparable rotator cuff tears. Our findings revealed that spin in the abstract tended to favor the balloon spacer intervention. Further efforts are required in the future to mitigate spin within the abstracts of published manuscripts.

Abstract
Background Total ankle arthroplasty (TAA), first developed as an alternative to ankle arthrodesis, has become an increasingly popular management option for end-stage ankle arthritis. Prior studies have shown commercial insurance payers base their coverage criteria on limited and low level of evidence research. This study aims to quantify and describe the evidence insurance companies use to support TAA coverage policies. Methods The top 11 national commercial health insurance payers for TAA were identified. A google search was performed to identify payer coverage policies. Policy documents were examined and cited references were classified by type of reference as well as reviewed for level of evidence (LOE). Specific coverage criteria for each individual payer were then extracted. Criteria were compared to assess for similarities among commercial payers. Finally, all references cited by each payer were examined to determine whether they mentioned the specific payer criteria. Results Six of the 11 payers had accessible coverage policies. The majority of cited references were primary journal articles (145, 60.9%) and the majority of references cited (179, 75.2%) were level III or level IV evidence. We found significant homogeneity in coverage criteria among payers. In addition, cited sources inconsistently mentioned specific payer coverage criteria. Conclusion This study demonstrates that commercial insurance payers rely on the relatively low level of currently available scientific evidence when formulating coverage policies for TAA use and adopt criteria that have not been thoroughly analyzed in the literature. More high level of evidence research is needed to help clinicians and insurance companies further refine indications for TAA so that patients who might benefit from the procedure are adequately covered. Level of Evidence Level IV, review.

Abstract
The obesity epidemic in the United States continues to grow with more than 40% of individuals now classified as obese (body mass index >30). Obesity has been readily demonstrated to increase the risk of developing hip and knee osteoarthritis and is known to increase the risk of complications following joint arthroplasty. Weight loss prior to arthroplasty may mitigate this risk of complications; however, the existing evidence remains mixed with no clear consensus on the optimal method of weight loss and timing prior to arthroplasty. Treatment options for weight loss have included nonsurgical lifestyle modifications consisting of structured diet, physical activity, and behavioral modification, as well as bariatric and metabolic surgery (ie, sleeve gastrectomy, Roux-en-Y gastric bypass, and the adjustable gastric band). Recently, glucagon-like peptide-1 receptor agonists have gained notable popularity within the scientific literature and media for their efficacy in weight loss. The aim of this review is to provide a foundational primer for joint arthroplasty surgeons regarding the current and emerging options for weight loss to aid surgeons in shared decision-making with patients prior to arthroplasty.

Abstract
PURPOSE To identify, describe and account for the incidence of spin in systematic reviews and meta-analyses of tendon transfer for the treatment of massive, irreparable rotator cuff tears (MIRCT). The secondary objective was to characterize the studies in which spin was identified and to determine whether identifiable patterns exist among studies with spin. METHODS This study was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Each abstract was assessed for the presence of the 15 most common types of spin derived from a previously established methodology. General data that were extracted included study title, authors, publication year, journal, level of evidence, study design, funding source, reported adherence to PRISMA guidelines, preregistration of the study protocol, and methodologic quality per A Measurement Tool to Assess Systematic Reviews Version 2 (AMSTAR 2). RESULTS The search yielded 53 articles, of which 13 were included in the final analysis. Articles were excluded if they were not published in a peer reviewed journal, not written in English, utilized cadaveric or nonhuman models, or lacked an abstract with accessible full text. 53.8% (7/13) of the included studies contained at least 1 type of spin in the abstract. Type 5 spin ("The conclusion claims beneficial effect of the experimental treatment despite a high risk of bias in primary studies") was the most common, appearing in 23.1% (3/13) of included abstracts. Nine of the spin categories did not appear in any of the included abstracts. A lower AMSTAR 2 score was significantly associated with the presence of spin in the abstract (p<0.006). CONCLUSION Spin is highly prevalent in the abstracts of systematic reviews and meta-analyses concerning tendon transfer for massive rotator cuff tears. A lower overall AMSTAR 2 rating was associated with a higher incidence of spin. Future studies should continue to explore the prevalence of spin in orthopedic literature and identify any factors that may contribute to its presence.

Abstract
Purpose To identify the quantity and types of spin present in systematic reviews and meta-analyses of ulnar collateral ligament reconstruction (UCLR) outcomes and to characterize the studies with spin to determine if any patterns exist. Methods This study was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In August 2022, PubMed, Scopus, and SportDiscus databases were searched using the terms "ulnar collateral ligament reconstruction" AND "systematic review" OR "meta-analysis." Each abstract was assessed for the presence of the 15 most common types of spin derived from a previously established methodology. General data that were extracted included study title, authors, publication year, journal, level of evidence, study design, funding source, reported adherence to PRISMA guidelines, preregistration of the study protocol, and methodologic quality per A Measurement Tool to Assess Systematic Reviews Version 2 (AMSTAR 2). Results In total, 122 studies were identified during the preliminary search, of which 19 met the inclusion criteria. Each study had at least 1 form of spin. The most common type of spin identified was type 5 ("The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies") (7/19, 36.8%). AMSTAR type 9 ("Did the review authors use a satisfactory technique for assessing the RoB [risk of bias] in individual studies that were included in the review?") was associated with both a lower Clarivate Impact Factor (P = .001) and a lower Scopus CiteScore (P = .015). Studies receiving external funding were associated with the failure to satisfy AMSTAR type 3 ("Did the review authors explain their selection of the study designs for inclusion in the review?") (P = .047). Conclusions Spin is highly prevalent in the abstracts of systematic reviews and meta-analyses that investigate the outcomes of UCLR. Clinical Relevance Spin has been identified in peer-reviewed articles published on various topics, including many in orthopaedics. Systematic reviews and meta-analyses contain the most comprehensive evidence regarding a clinical question, so it is important to identify spin that may be included in these reports. Greater efforts are needed to ensure that the abstracts of papers accurately represent the results in the full text.

Abstract
OBJECTIVES Occult instability in minimally displaced lateral compression (LC) pelvic ring injuries may have clinical relevance for treatment. We describe two novel LC pelvis fracture stress examinations - pelvic binder stress radiography (PBR) and pelvic binder stress bladder manometry (PBM) - which do not require sedation, anesthesia, patient transport, or radiation of personnel. METHODS A biomechanical study was performed with five fresh elderly cadavers. Sequential osteotomies of the pelvis simulated increasingly unstable LC pelvis fracture patterns (OTA/AO 61A2.2, 61B1.1a, 61B1.1b, 61B2.1). Compressive force was quantitatively applied using a pelvic binder and scale. Pelvis fracture displacement was measured on AP and inlet fluoroscopic views. Pelvic bladder pressure (PBM) was measured using a Foley catheter as a water column. RESULTS Fracture displacement strongly correlated with force applied (R2=0.600-0.963). PBR discriminated between simulated LC injuries. Mean displacement of 61B1.1b injuries >1cm was observed at 3.8kg on AP view and 5kg on inlet view. Mean displacement of 61B1.1a injuries >1cm was observed at 8.2kg on AP view and 9.3kg on inlet view. 61A2.2 injuries did not displace >1cm at forces up to 10kg. >95% of 61B1.1a and 61B1.1b injuries displaced >1cm at 10kg. PBM moderately correlated with force applied (R2=0.517-0.842) but did not discriminate between LC injuries. CONCLUSIONS PBR is feasible, precisely quantified occult mechanical instability in simulated LC pelvis fractures in response to reproducible applied force, and discriminated between simulated LC pelvis fractures. PBM did not discriminate between simulated LC fractures. A clinical trial to validate the safety and efficacy of PBR for assessing occult instability in LC pelvis fracture is warranted.

Abstract
BACKGROUND Simultaneous bilateral total hip arthroplasty (sbTHA) continues to be performed in patients who have bilateral end-stage osteoarthritis. However, few studies have evaluated the risk associated with this practice compared to unilateral total hip arthroplasty (THA). METHODS Using a large national database, primary, elective sbTHAs, and unilateral THAs were identified from January 1, 2015 to December 31, 2021. The sbTHAs were matched to unilateral THAs at a 1:5 ratio on age, sex, and pertinent comorbidities. Patient characteristics and comorbidities, and hospital factors were compared between both cohorts. Additionally, 90-day risk of postoperative complications, readmissions, and in-hospital deaths were assessed. After matching, 2,913 sbTHAs were compared to 14,565 unilateral THAs with an average age of 58.5 ± 10.0 years. RESULTS Compared to unilateral patients, sbTHA patients demonstrated higher rates of pulmonary embolism (PE) (0.4 versus 0.2%, P = .002), acute renal failure (1.2 versus 0.7%, P = .007), acute blood loss anemia (30.4 versus 16.7%, P < .001), and need for transfusion (6.6 versus 1.8%, P < .001). After accounting for confounders, sbTHA patients demonstrated increased risk of PE (adjusted odds ratio [aOR]: 3.76, 95% CI: 1.84 to 7.70, P < .001), acute renal failure (aOR: 1.83, 95% CI: 1.23 to 2.72, P = .003), acute blood loss anemia (aOR: 2.3, 95% CI: 2.10 to 2.53, P < .001), and transfusion (aOR: 4.08, 95% CI: 3.35 to 4.98, P < .001) compared to unilateral THA patients. CONCLUSION The practice of performing sbTHA was associated with an increased risk of PE, acute renal failure, and risk of transfusion. Careful evaluation of patient-specific risk factors is warranted when considering these bilateral procedures.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in multimodal pain control following total joint arthroplasty (TJA). However, few studies have assessed the complications associated with the combinations of NSAIDs in this population despite the known risks associated with this class of medications. The Premier Healthcare Database was queried to identify adults who underwent primary total hip or knee arthroplasty from 2005-2014. The following most common inpatient combinations of NSAIDs were chosen for analysis: aspirin + celecoxib (A + C), toradol + aspirin (T + A), toradol + ibuprofen (T + I), celecoxib + ibuprofen (C + I), ibuprofen + aspirin (I + A), and toradol + celecoxib (T + C). Primary outcomes included acute kidney injury (AKI), gastrointestinal bleed, and stroke. Secondary outcomes included periprosthetic joint infection (PJI), deep vein thrombosis, and pulmonary embolism. Univariate and multivariate regression analyses were used to compare differences and address confounds. Overall, 195,833 patients were identified. After controlling for confounds, increased odds of AKI was associated with A + C (adjusted odds ratio [aOR]: 1.20, 95% confidence interval [CI]: 1.09-1.34, p < 0.001) and decreased odds was associated with T + A (aOR 0.76, 95% CI: 0.69-0.83, p < 0.001). Increased odds of stroke was associated with A + C (aOR: 1.80, 95% CI: 1.15-2.84, p = 0.011); T + I (aOR 3.48, 95% CI: 1.25-9.73, p = 0.017); and I + A (aOR 4.29, 95% CI: 1.06-17.9, p = 0.046). Increased odds of PJI was associated with C + I (aOR: 10.3, 95% CI: 1.35-78.3, p = 0.024). In the TJA patient population, NSAID pairings should be regarded as distinct entities. Our results suggest that combinations including A + C, T + I, I + A, and C + I should be used cautiously. With this knowledge, providers should consider tailoring NSAID prescriptions appropriately.

Abstract
Background Upper extremity injuries account for approximately 16.9% of football injuries in the National Collegiate Athletic Association (NCAA). Purpose To determine the epidemiology, management, and outcomes of hand/wrist injuries in collegiate football athletes so as to identify factors associated with surgical intervention and delayed return to play (RTP). Study Design Descriptive epidemiology study. Methods We retrospectively reviewed hand/wrist injuries that occurred within a single NCAA Division I football team from January 1, 2003, to December 31, 2020. Data analyzed included player position, college seniority, injury characteristics, injury management, surgical procedures performed, and timing of RTP. A univariate analysis was performed to identify factors associated with increased risk for surgical intervention and delayed (>21 days) RTP after hand and wrist injury in this cohort. Results Overall, 124 patients with 168 hand/wrist injuries were identified (9.9 wrist/hand injuries per year). Sprain of the thumb metacarpophalangeal (MCP) joint ulnar collateral ligament (UCL) was the most common diagnosis (19.6%). Surgery was required in 22% of injuries, with injury of the UCL of the thumb MCP joint (8/37) being the most common indication. Injuries occurring during competitive games (odds ratio = 4.29; 95% CI, 1.2-15.9) were associated with an increased risk for surgery. Most (70%) injuries did not lead to time missed from football, whereas the remaining 30% resulted in an average of 33 ± 36 days missed. Conclusion Over 17 athletic seasons, the annual incidence of hand and wrist injury in these NCAA Division I football players was 9.9 injuries per year, with 22% requiring surgical treatment. Injury to the UCL of the thumb MCP joint was the most common injury and indication for surgery, and 30% of injuries resulted in approximately 1 month lost. Injuries sustained in games were associated with operative management and delayed RTP.

Abstract
The management of critical-sized bone defects caused by nonunion, trauma, infection, malignancy, pseudoarthrosis, and osteolysis poses complex reconstruction challenges for orthopedic surgeons. Current treatment modalities, including autograft, allograft, and distraction osteogenesis, are insufficient for the diverse range of pathology encountered in clinical practice, with significant complications associated with each. Therefore, there is significant interest in the development of delivery vehicles for growth factors to aid in bone repair in these settings. This article reviews innovative strategies for the management of critical-sized bone loss, including novel scaffolds designed for controlled release of rhBMP, bioengineered extracellular vesicles for delivery of intracellular signaling molecules, and advances in regional gene therapy for sustained signaling strategies. Improvement in the delivery of growth factors to areas of significant bone loss has the potential to revolutionize current treatment for this complex clinical challenge.

Abstract
This is a case of a 57-year-old healthy woman with traumatic bilateral distal biceps tendon rupture with tendon retraction requiring reconstruction. The functional outcomes were recorded pre-operatively and at 3 months, 6 months, 1 year and 2 years postoperatively. Conclusion: Distal biceps tendon rupture usually occurs in male patients; however, this injury may occur in females. Delay in treatment may result in tendon degeneration precluding repair. Distal biceps tendon reconstruction with Achilles allograft yielded favorable outcome in a middle-aged female patient who sustained bilateral distal biceps tendon rupture.

Abstract
BACKGROUND The relationship between anemia and the risk of venous thromboembolism (VTE) following total knee arthroplasty (TKA) and total hip arthroplasty (THA) remains unclear. Red blood cell (RBC) transfusions, which have been shown to have thrombogenic effects, may explain conflicting data. This study sought to elucidate the relationship between anemia, RBC transfusions, and VTE following total joint arthroplasty (TJA). METHODS Using the International Classification of Diseases, Tenth Revision (ICD-10) and Current Procedural Terminology (CPT) codes, the Premier Healthcare Database was queried for all adults who underwent primary elective THA or TKA from January 2015 to December 2020. Patients were classified into 3 cohorts: those who did not have a diagnosis of anemia and did not receive an RBC transfusion (the control group), those with acute blood loss anemia who did not receive a transfusion (the anemia without transfusion group), and those with acute blood loss anemia who did receive a transfusion (the anemia with transfusion group). The primary outcomes assessed were the 90-day rate and risk of deep vein thrombosis (DVT), pulmonary embolism (PE), and aggregate VTE. Analysis of variance and pairwise comparisons were used to compare groups. Multivariable analyses were performed to account for confounding factors. RESULTS The 1,290,815 patients identified as having undergone TJA included 1,078,507 control patients (83.6%), 198,233 patients who had anemia without transfusion (15.4%), and 14,075 patients who had anemia and transfusion (1.1%). Age, sex, race, length of hospital stay, and hospital costs were significantly different between the 3 groups. After adjusting for confounding factors, there was no difference between the anemia without transfusion group and the control group with regard to DVT (adjusted odds ratio [OR], 0.97 [95% confidence interval (CI), 0.89 to 1.06]; p = 0.500), PE (adjusted OR, 1.04 [95% CI, 0.92 to 1.18]; p = 0.543), and VTE (adjusted OR, 0.99 [95% CI, 0.92 to 1.06]; p = 0.697). However, patients with anemia and transfusion had an increased risk of PE (adjusted OR, 1.83 [95% CI, 1.34 to 2.51]; p < 0.001) and VTE (adjusted OR, 1.39 [95% CI, 1.14 to 1.70]; p = 0.001) compared with patients in the control group. CONCLUSIONS Patients with acute blood loss anemia who received a transfusion were at increased risk for developing VTE following TJA, whereas patients with anemia who did not receive a transfusion were not. Orthopaedic surgeons need to be aware of the risks of transfusion and individualize the use of transfusions in their patients. LEVEL OF EVIDENCE Prognostic Level III .

Abstract
Background Since its approval, reverse total shoulder arthroplasty (rTSA) has continued to increase in usage, with expanding indications beyond rotator cuff arthropathy. Existing literature has captured further increased utilization over the last decade through 2017. However, this data has not been updated to include a contemporary cohort of patients. This study sought to determine the trends of anatomic total shoulder arthroplasty (aTSA), rTSA, and hemiarthroplasty (HA) usage based on primary diagnosis and total number of surgeons performing each procedure annually from 2016-2020. Methods Patients who underwent primary rTSA, aTSA, and HA from 2016-2020 were identified in the Premier Healthcare Database. Primary indication diagnoses for procedures were identified using International Classification of Diseases 10th edition codes. Temporal trends in patient and hospital demographics, primary indication, and procedure utilization were captured on an annualized basis. The number of surgeons performing each procedure annually was noted. Descriptive statistics were employed with significance set at P < .05. Results From 2016 to 2020, 154,499 patients undergoing primary shoulder arthroplasty were identified: 48,890 aTSA, 95,808 rTSA, and 9801 HA. In 2016, rTSA comprised a slight majority (55%) of all arthroplasty cases but increased to nearly 70% of all arthroplasty cases in 2020. The absolute numbers of aTSA and HA cases decreased over time, while rTSA volume increased from 14,781 in 2016 to a high of 23,644 cases in 2019. There was a corresponding 12% increase in the number of surgeons performing rTSA across the same time period, contrasted with a 42.1% decrease in surgeons performing HA and a 14.3% decrease for aTSA. Glenohumeral osteoarthritis remains the most common indication for rTSA and aTSA, while HA is used primarily for proximal humerus fractures or hardware complications. Conclusion The volume of primary rTSA in the United States has continued to increase from 2016 to 2020 with concurrent decreases in the number of primary aTSA and HA cases performed. Primary rTSA accounts for nearly 70% of all primary shoulder arthroplasty cases. The number of surgeons performing rTSA continues to increase, while there has been a decrease in the number of surgeons performing aTSA and HA.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is a highly successful surgical procedure that decreases pain and improves function. Many patients who undergo TKA may require surgical intervention on both extremities because of bilateral osteoarthritis. The purpose of this study was to evaluate the safety of simultaneous bilateral TKA compared with that of unilateral TKA. METHODS Patients who underwent unilateral or simultaneous bilateral primary, elective TKA from 2015 to 2020 were identified using the Premier Healthcare Database. Subsequently, the simultaneous bilateral TKA cohort was matched to the unilateral TKA cohort in a 1:6 ratio by age, sex, race, and presence of pertinent comorbidities. Patient characteristics, hospital factors, and comorbidities were compared between the cohorts. The 90-day risks of postoperative complications, readmission, and in-hospital death were assessed. Differences were assessed using univariable regression, and multivariable regression analyses were performed to account for potential confounders. RESULTS Overall, 21,044 patients who underwent simultaneous bilateral TKA and 126,264 matched patients who underwent unilateral TKA were included. After accounting for confounding factors, patients who underwent simultaneous bilateral TKA demonstrated a significantly increased risk of postoperative complications, including pulmonary embolism (adjusted odds ratio [OR], 2.13 [95% confidence interval (CI), 1.57 to 2.89]; p < 0.001), stroke (adjusted OR, 2.21 [95% CI, 1.42 to 3.42]; p < 0.001), acute blood loss anemia (adjusted OR, 2.06 [95% CI, 1.99 to 2.13]; p < 0.001), and transfusion (adjusted OR, 7.84 [95% CI, 7.16 to 8.59]; p < 0.001). Patients who underwent simultaneous bilateral TKA were at increased risk of 90-day readmission (adjusted OR, 1.35 [95% CI, 1.24 to 1.48]; p < 0.001). CONCLUSIONS Simultaneous bilateral TKA was associated with increased rates of complications including pulmonary embolism, stroke, and transfusion. Orthopaedic surgeons and patients should consider these potential complications when contemplating simultaneous bilateral TKA. When simultaneous bilateral TKA is pursued, patient counseling and thorough medical optimization should be performed. LEVEL OF EVIDENCE Therapeutic Level III .

Abstract
Background Existing systematic reviews have sought to characterize the relative donor-site morbidity of bone-patellar tendon-bone (BTB) and quadriceps tendon (QT) grafts after anterior cruciate ligament reconstruction (ACLR). However, no studies have reported the pooled proportions of patellar fractures and donor tendon ruptures across the body of literature. Purpose To estimate the proportion of patellar fractures, patellar tendon ruptures, and QT ruptures associated with BTB or QT autograft harvest during ACLR using published data. Study Design Systematic review; Level of evidence, 4. Methods A meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using 3 online databases (PubMed, Scopus, and Web of Science). A total of 800 manuscripts were included in the initial research of peer-reviewed articles in English that reported extensor mechanism complications associated with graft harvest in patients after ACLR. Pooled proportions of patellar fractures, patellar tendon ruptures, and QT ruptures were calculated for each graft type (BTB, QT) using a random-effects model for meta-analysis. Results A total of 28 studies were analyzed. The pooled proportion of patellar fractures was 0.57% (95% CI, 0.34%-0.91%) for the BTB harvest and 2.03% (95% CI, 0.78%-3.89%) for the QT harvest. The proportion of patellar tendon ruptures was 0.22% (95% CI, 0.14%-0.33%) after the BTB harvest, and the proportion of QT ruptures was 0.52% (95% CI, 0.06%-1.91%) after the QT harvest. The majority of included studies (16/28 [57.1%]) had an evidence level of 4. Conclusion Based on the current literature, the proportion of extensor mechanism complications after ACLR using either a BTB or a QT autograft is low, indicating that the extensor mechanism harvest remains a safe option. A higher proportion of patellar fractures was noted for QT grafts and a higher proportion of donor tendon ruptures was noted for QT grafts compared with BTB grafts.

Abstract
PURPOSE The purpose of this study was to measure the harms-related reporting among randomized controlled trials (RCTs) cited as supporting evidence for the American Academy of Orthopaedic Surgeons clinical practice guidelines regarding the management of distal radius fractures. METHODS We adhered to the guidance for reporting metaresearch and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines throughout the course of this investigation. We used the American Academy of Orthopaedic Surgeons clinical practice guidelines for distal radius fractures available on Orthoguidelines.org. A linear regression analysis was conducted to model the relationship between the year of publication and the total Consolidated Standards of Reporting Trials percentage adherence over time. RESULTS Thirty-five RCTs were included in the final sample. The average number of Consolidated Standards of Reporting Trials Extension for Harms items adequately reported across all included RCTs was 9.2 (9.2/18, 50.9%). None of the included trials adequately reported all 18 items. Ten items had a compliance of more than 50% (10/18, 55.6%), 4 items had a compliance of 20%-50% (4/18, 22.2%), and 4 items had a compliance of less than 20% (4/18, 22.2%). The results of the linear regression model showed no significant improvement in Consolidated Standards of Reporting Trials Harms reporting over time. CONCLUSIONS Adverse events are incompletely reported among RCTs cited as supporting evidence for American Academy of Orthopaedic Surgeons clinical practice guidelines for the management of distal radius fractures. CLINICAL RELEVANCE Given our findings, specific attention should be paid to improving the standardization of the classification of adverse events to facilitate ease in the reporting process.

Abstract
Background Spin is defined as the use of specific reporting strategies to highlight the beneficial effect of a treatment despite nonsignificant results. The presence of spin in peer-reviewed literature can negatively impact clinical and research practices. The purpose of this study was to identify the quantity and types of spin present in primary studies and systematic reviews using suture tape augmentation for ankle instability as a model. Methods This study was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Each abstract was assessed for the presence of the 15 most common types of spin. Extracted data included study title, authors, publication year, journal, level of evidence, study design, funding, reported adherence to PRISMA guidelines, and PROSPERO registration. Full texts of systematic reviews were used in the assessment of study quality per A Measurement Tool to Assess Systematic Reviews Version 2 (AMSTAR 2). Results Nineteen studies were included in the final sample. At least 1 type of spin was identified in each study except one (18 of 19, 94.7%). The most common type of spin observed was type 3 ("selective reporting or overemphasis on efficacy outcomes or analysis favoring the beneficial effect of the experimental intervention") (6 of 19, 31.6%), The second most reported category of spin was type 4 ("the conclusion claims safety based on non-statistically significant results with a wide confidence interval") (4 of 19, 21.1%). Among systematic reviews, we identified type 5 ("the conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies") in 4 out of 6 (66.7%) of the articles that were included. No significant associations were found between study characteristics and type of spin. Conclusion In this exploration of the introduction of a new technology, we identified spin to be highly present in the abstracts of primary studies and systematic reviews concerning suture tape augmentation for ankle instability. Steps should be taken by scientific journals to ensure that spin is minimized in the abstract to accurately reflect the quality of the intervention.

Abstract
Background This study aims to examine differences in postoperative complications and opioid consumption associated with perioperative peripheral nerve block (PNB) utilization during primary total knee arthroplasty (TKA). Methods The Premier Healthcare Database was queried for adult patients who underwent primary, elective TKA from 2015 to 2020. Patients who received a femoral or adductor canal PNB were compared to patients who did not. PNB utilization was trended from 2015 to 2020. Univariate and multivariate regression analyses were performed to assess differences in the 90-day risk of postoperative complications between groups. The average inpatient opioid consumption in morphine milligram equivalents was assessed as a function of length of stay. Results Overall, 609,991 patients were included. PNB utilization increased from 9.29% in 2015 to 30.3% in 2020. After controlling for confounders, the PNB cohort was more likely to have same-day discharge (adjusted odds ratio [aOR] 1.88) and had a decreased risk of periprosthetic joint infection (aOR 0.87), pulmonary embolism (aOR 0.81), and respiratory failure (aOR 0.78). However, there was an increased risk of seroma (aOR 1.75) and hematoma (aOR 1.22) associated with PNB utilization. Lower average overall opioid exposure was seen in the PNB cohort vs no-PNB cohort (82.1 ± 194.7 vs 89.4 ± 214.1 morphine milligram equivalents, P < .001). Conclusions PNB utilization during primary TKA is associated with a shorter length of stay and decreased risk of multiple postoperative complications, as well as reduced postoperative opioid consumption. These data provide evidence in support of the safety and efficacy of this emerging practice. However, the clinical relevance of an increased risk of seroma and hematoma formation may warrant further investigation.

Abstract
BACKGROUND Cervical disc arthroplasty (CDA) was originally approved by the US Food and Drug Administration (FDA) in 2007 as a motion-sparing procedure to treat cervical degenerative disc disease. Since then, promising results from randomized control trials have led to increasing popularity. However, data discussing monetary trends are limited. The aim of this study was to determine how utilization, hospital charges, and Medicare physician reimbursement for CDA have changed over time. METHODS In this retrospective cohort study, International Classification of Diseases procedure codes were used to identify all patients who underwent CDA from 2007 to 2017 in the National Inpatient Sample database. The Physician Fee Schedule Look-up Tool from the Centers for Medicare and Medicaid Services was queried for primary CDA using current procedural terminology codes to determine Medicare physician reimbursement from 2009 to 2021. Nominal monetary values were adjusted for inflation using the Consumer Price Index and inflation-adjusted data reported in 2021 US dollars. RESULTS A total of 33,079 weighted patients who underwent CDA were included for analysis. CDA utilization increased by 183% from 2007 to 2017, with Medicare beneficiary utilization increasing 149%. Inflation-adjusted total hospital charges for CDA increased by 22.4%. However, inflation-adjusted Medicare physician reimbursement fell by 1.20% per year, demonstrating a total decrease of 12.9%, starting at $1928 in 2009 and declining to $1679 in 2021. CONCLUSIONS While utilization and total hospital charges for CDA continue to rise, Medicare physician reimbursement has not shown the same trend. In fact, inflation-adjusted reimbursement has seen a steady decline since FDA approval in 2007. If this trend persists, it may become unsustainable for physicians to continue offering CDA to Medicare patients. As disproportionate increases in hospital charges incentivize a transition to outpatient CDA, stricter patient selection criteria associated with outpatient procedures may create health care disparities for Medicare patients and those with higher comorbidity burden. CLINICAL RELEVANCE This study shows the decreasing reimbursement trends for CDA, which may disproportionately affect Medicare patients and those with increased comorbidities. LEVEL OF EVIDENCE: 3

Abstract
BACKGROUND Aspirin may be effective at preventing venous thromboembolism following total knee arthroplasty (TKA) or total hip arthroplasty (THA). Current evidence is limited by bias as many surgeons who use aspirin prescribe for high-risk patients alternative chemoprophylactic agents. Therefore, this study aimed to evaluate the risk of pulmonary embolism (PE) and deep vein thrombosis (DVT) in patients who received aspirin and warfarin while accounting for surgeon selection bias. METHODS A national database was queried for patients undergoing primary elective TKA or THA from 2015 to 2020. Patients whose surgeon used aspirin in >90% of their patients were compared to patients whose surgeon used warfarin in >90% of cases. Instrumental variable analyses were performed to assess for PE, DVT, and transfusion while accounting for selection bias. Among TKA patients, 26,657 (18.8%) were in the warfarin cohort and 115,005 (81.2%) were in the aspirin cohort. Among THA patients, 13,035 (17.7%) were in the warfarin cohort and 60,726 (82.3%) were in the aspirin cohort. RESULTS Analyses were unable to identify a difference in the risk of PE (TKA: adjusted odds ratio [aOR]: 0.98, P = .659; THA: aOR = 0.93, P = .310) and DVT (TKA: aOR = 1.05, P = .188; THA: aOR = 0.96, P = .493) between the aspirin and warfarin cohorts. However, the aspirin cohort was associated with a lower risk of transfusion (TKA: aOR = 0.58, P < .001, THA: 0.84, P < .001). DISCUSSION After accounting for surgeon selection bias, aspirin was as effective as warfarin at preventing PE and DVT following TKA and THA. Furthermore, aspirin was associated with a lower risk of transfusion compared to warfarin.

Abstract
BACKGROUND An optimal venous thromboembolism prophylaxis agent should balance efficacy and safety. While rivaroxaban provides effective venous thromboembolism prophylaxis after total joint arthroplasty, it may be associated with higher rates of bleeding. This study aimed to compare the safety and efficacy of rivaroxaban to aspirin and enoxaparin. METHODS A large national database was queried for patients who underwent elective primary total hip (THA) or total knee arthroplasty (TKA) from January 2015 through December 2020 who received rivaroxaban, aspirin, or enoxaparin. Multivariate analyses were performed to assess the 90-day risk of bleeding and thromboembolic complications. Among TKA patients identified, 86,721 (10.8%) received rivaroxaban, 408,038 (50.8%) received aspirin, and 108,377 (13.5%) received enoxaparin. Among THA patients, 42,469 (9.5%) received rivaroxaban, 242,876 (54.5%) received aspirin, and 59,727 (13.4%) received enoxaparin. RESULTS After accounting for confounding factors, rivaroxaban was associated with increased risk of transfusion (TKA: adjusted odds ratio [aOR] = 2.58, P < .001; THA: aOR 1.64, P < .001), pulmonary embolism (TKA: aOR = 1.25, P = .007), and deep vein thrombosis (TKA: aOR = 1.13, P = .022) compared to aspirin. Compared to enoxaparin, rivaroxaban was associated with an increased risk of combined bleeding events (TKA: aOR = 1.07, P < .001, THA: aOR = 1.11, P < .001), but decreased risk of combined prothrombotic events (THA: aOR = 0.85, P = .036). CONCLUSION Rivaroxaban chemoprophylaxis following TKA and THA was associated with an increased risk of bleeding and prothrombotic complications compared to aspirin and enoxaparin.

Abstract
BACKGROUND The SARS-CoV-2 (COVID-19) pandemic has dramatically disrupted orthopaedic surgery practice patterns. This study aimed to examine differences between patients who underwent total joint arthroplasty (TJA) before the pandemic compared to 2020 and 2021. METHODS A retrospective cohort study was performed on all patients who underwent elective inpatient TJA from January 2017 to December 2021 using a national large database. Descriptive statistics were utilized to trend length of stay (LOS) and patient age. Patient demographics, discharge destinations, and rates of medical comorbidities were assessed for patients undergoing TJA in 2020 and 2021 compared to patients from prepandemic years (2017 to 2019). Overall, 1,173,366 TJAs were identified (2017 to 2019: 810,268 TJAs, average 270,089 cases/year; 2020: 175,185 TJAs; 2021: 187,627 TJAs). There was a 35.3% and 30.5% decrease in 2020 and 2021, respectively, when compared to the prepandemic annual average. RESULTS Average LOS decreased from 1.6 days in January 2020 to 0.9 days by December 2021. Same-day discharges increased from 6.2% of cases in 2019 to 30.5% in 2021. Discharge to skilled nursing facilities (SNF) reduced from 11.3% in 2017 to 2019 to 4.3% and 4.5% in 2020 and 2021, respectively. Patients ≥70 years old undergoing elective TJA decreased from 39.6% in 2017 to 2019 to 29.2% in April 2020. CONCLUSION In response to the COVID-19 pandemic, same-day discharges following primary elective TJA increased markedly, the average LOS decreased, discharges to SNFs decreased, and a preferential shift toward younger patients was observed.

Abstract
BACKGROUND Tranexamic acid (TXA) utilization during total joint arthroplasty (TJA) has become ubiquitous. However, concerns remain regarding the risk of thrombotic complications. The goal of this study was to examine the risk of prothrombotic complications in patients who received TXA during total knee (TKA) and total hip arthroplasty (THA). METHODS The Premier Healthcare Database was queried for patients who underwent elective TJA. TXA utilization trends were described from 2008 to 2020. Two analyses were performed using ICD-10 codes from 2016 to 2020: (1) patients who received TXA compared to patients who did not receive TXA and, (2) to account for surgeon selection bias, patients whose surgeon utilized TXA consistently (≥90% of cases) compared to patients whose surgeons used TXA infrequently (≤30% of cases). Multivariate and instrumental variable analyses (IVA) were performed to assess outcomes while accounting for confounding factors. TXA utilization increased from 0.1% of cases in 2008 to 89.2% in 2020. From 2016 to 2020, 1,120,858 TJAs were identified (62.1% TKA, 27.9% THA), of which 874,627 (78.0%) received TXA. RESULTS Patients who received TXA were at lower risk of prothrombotic (adjusted Odds Ratio (aOR) 0.82, P < .001), bleeding (aOR 0.75, P < .001), and infectious complications (aOR 0.91, P < 0.001). Furthermore, patients who underwent surgery from surgeons who utilized TXA consistently were at lower risk for prothrombotic (aOR 0.90, P < .001) and bleeding (aOR 0.72, P < .001) complications. CONCLUSION The widespread utilization of TXA during elective TJA was not associated with increased rates of prothrombotic complications. These findings persisted after accounting for surgeon selection bias. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Wear between the femoral head and acetabular liners continues to limit the longevity of total hip arthroplasty implants despite advances in implant materials. The purpose of this meta-analysis was to compare linear wear rates of cobalt-chromium (CoCr) and fourth-generation ceramic femoral heads on highly cross-linked polyethylene (XLPE) liners. METHODS A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted to identify all studies between 2003 and 2020 that examined in vivo wear rates of either fourth-generation ceramics or CoCr femoral heads on XLPE liners. Studies were analyzed in a weighted means analysis of wear rates and a random effects meta-analysis. RESULTS A total of 36 studies met inclusion criteria (1,657 CoCr and 659 ceramic patients). The pooled, weighted mean wear rate was 0.063 mm/year (standard deviation [SD]: 0.061, confidence interval [CI]: 0.049-0.077) for CoCr and 0.047 mm/year (SD: 0.057, CI: 0.033-0.062; P < .01) for ceramic (P < .01). A meta-analysis of 4 studies directly comparing ceramic and CoCr found that CoCr heads demonstrated 0.029 mm/year more wear than ceramic heads (95% CI: 0.026-0.059, P = .306). Mean wear for 32-mm heads was significantly higher for ceramic (P < .01), while mean wear for 36-mm heads was significantly higher for CoCr (P < .01). CONCLUSION Fourth-generation ceramic femoral heads were found to have significantly lower wear rates than CoCr heads. Unlike previous studies, this meta-analysis included only in vivo studies and those with the same generation of highly XLPE liners.

Abstract
BACKGROUND Total hip arthroplasty (THA) patients often receive routine radiographs in the year following their index surgery. This study sought to investigate the clinical and economic value of obtaining routine postoperative hip radiographs for asymptomatic patients following primary elective THA. METHODS A retrospective cohort study of consecutive patients who underwent primary elective THA from 2016 to 2019 was conducted. Patients undergoing nonelective or revision THA, radiographic follow-up <10 months, and patients aged <18 years were excluded. All radiographs were reviewed for abnormalities in the first postoperative year by an arthroplasty fellowship-trained orthopaedic surgeon, blinded to the symptoms of the patient. RESULTS Of the 327 patients (351 hips) included, 57.2% were women and 68.2% were White, with an average age of 65 years (range, 22-97 years) and average body mass index of 29.1 kg/m2 (range, 16.2-49.8 kg/m2). Only four (0.4%) radiographic series revealed abnormalities with the potential to alter postoperative management. One patient experienced a change in management directly related to their abnormal finding (closed reduction for dislocation at 10.2 months postoperatively). The remaining three abnormal radiographic findings included femoral stem subsidence, progressive radiolucencies around an acetabular component, and cement mantle fracture. The average cost for each radiographic series was $155.27, resulting in total direct charges of $167,691.60. CONCLUSION Routine postoperative radiographs may be of limited utility in the asymptomatic patient in the first year following elective primary THA. Consideration should be given to limit postoperative radiographs following standard elective THA, while reserving postoperative radiographic evaluation for patients who are symptomatic.

Abstract
Purpose To report the outcomes of routine arthroscopic meniscectomy in National Collegiate Athletic Association (NCAA) Division I Football players. Methods NCAA athletes who underwent arthroscopic meniscectomy over 5 years were included. Players who had incomplete data, previous knee surgery, ligamentous injury, and/or microfractures were excluded. Data collected were player position, timing of surgery, procedures performed, return to play (RTP) rate and time, and postoperative performance. Continuous variables were analyzed with Student t-tests or a one-way analysis of variance. Results Thirty-six athletes (38 knees) who underwent arthroscopic partial meniscectomy (31 lateral, 7 medial) were included. The mean RTP time was 71 ± 39 days. The mean RTP time in athletes who underwent in-season surgery) was significantly shorter than the RTP in athletes who had off-season surgery (58 ± 41 days vs 85 ± 33 days, P < .05). The mean RTP in 29 athletes (31 knees) with lateral meniscectomy was similar to the 7 athletes (7 knees) who had medial meniscectomy (70 ± 36 vs 77 ± 56, P = .6803). The mean RTP time was similar between football players who underwent isolated lateral meniscectomy and those who had lateral meniscectomy with chondroplasty (61 ± 36 days vs 75±41 days, P = .32). Athletes played an average of 7.7 ± 4.9 games the season they returned; position category and anatomical compartment of the knee lesion had no bearing on number of games played (P = .1864 and P = .425). Conclusions NCAA Division 1 football players who underwent arthroscopic partial meniscectomy RTP at approximately 2.5 months' postoperatively. Athletes who underwent off-season surgery had longer RTP time compared with those who underwent in-season surgery. RTP time and performance after surgery did not differ based on player position, anatomical location of the lesions, or chondroplasty at the time of meniscectomy. Level of Evidence Level IV, therapeutic case series.

Abstract
The management and definitive treatment of segmental bone defects in the setting of acute trauma, fracture non-union, revision joint arthroplasty, and tumor surgery are challenging clinical problems with no consistently satisfactory solution. Orthopaedic surgeons are developing novel strategies to treat these problems, including three-dimensional (3D) printing combined with growth factors and/or cells. This article reviews the current strategies for management of segmental bone loss in orthopaedic surgery, including graft selection, bone graft substitutes, and operative techniques. Furthermore, we highlight 3D printing as a technology that may serve a major role in the management of segmental defects. The optimization of a 3D-printed scaffold design through printing technique, material selection, and scaffold geometry, as well as biologic additives to enhance bone regeneration and incorporation could change the treatment paradigm for these difficult bone repair problems.

Abstract
BACKGROUND Despite known surgical volume reductions in 2020 during the height of the COVID-19 pandemic, no study has fully quantified the impact of the pandemic on the number of elective inpatient total hip (THA) and total knee arthroplasty (TKA) cases. The purpose of the present study was to analyze THA and TKA case volumes in the United States during the COVID-19 pandemic. METHODS The Premier Healthcare Database was utilized to identify adults undergoing primary elective THA or TKA from January 2017 to December 2020. The National Inpatient Sample was cross-referenced to provide nationwide representative sampling weights. Patients undergoing revision total joint arthroplasty (TJA) or non-elective surgery were excluded. Two quantitative models were created from both databases to estimate TJA case volume in 2020. Descriptive statistics were utilized to report monthly changes in elective TJA utilization throughout 2020. Univariate analyses were performed to compare differences between subgroups. RESULTS From 2017 to 2019, it was estimated that 1,006,000 elective inpatient TJAs (64.2% TKA and 35.8% THA) were performed annually. In 2020, an estimated 526,000 to 538,000 cases (62.0% TKA and 38.0% THA) were performed, representing a 46.5% to 47.7% decrease in nationwide volume from the prior 3-year average. Moreover, the elective TJA case volume for April 2020 was 1.9% of the average for that month from 2017 through 2019. Subsequently, case volumes for May and June increased compared with the volumes for those months from 2017 through 2019. There was then a decrease in cases for July, corresponding with the "second wave" of COVID-19, followed by an additional steady monthly decline through December, corresponding with the "third wave." Finally, the elective TJA cases for December 2020 represented only 41.0% of the average case volume for that month from 2017 through 2019. CONCLUSIONS In the midst of the 2020 COVID-19 pandemic, approximately 526,000 to 538,000 elective inpatient TJA cases were performed, representing a 46.5% to 47.7% decrease compared with the 3 previous years. The effects of the COVID-19 pandemic persisted through the end of that year, with decreased case volume through December 2020.

Abstract
Background Successful outcomes in total hip arthroplasty (THA) rely in part on accurate component positioning, which may be optimized through the use of computer navigation and robot-assistance. Therefore, we queried a large national database to characterize national trends in technology-assisted THA utilization, determine whether these technologies were associated with increased hospital charges, and identify demographic factors associated with technology-assisted THA. Methods Using the Nationwide Inpatient Sample database, patients that underwent conventional THA, computer-navigated THA, and robot-assisted THA from 2005 to 2018 were identified. Patient and hospital demographics, charge data, and payer characteristics were collected. Temporal trends in utilization were reported. Univariate analyses were performed to compare differences between groups with multiple logistic regression analysis to account for confounders. Results In total, 3,428,208 patients undergoing THA from 2005 to 2018 were identified, of which 63,136 (1.8%) used computer navigation and 32,660 (1.0%) used robot-assistance. National utilization of computer navigation in THA increased from 0.1% to 1.9% between 2005 and 2018, while utilization of robot-assisted THA increased from <0.1% to 2.1% from 2008 to 2018. On multivariate analysis, technology-assisted THA was most commonly performed in urban hospitals in the Northeastern United States. Median hospital charges were increased for technology-assisted THAs relative to conventional THAs ($66,089 ± $254 vs $55,418 ± $43). Conclusions Computer navigation and robot-assistance in THA demonstrated a consistent increase in utilization during the period examined, representing 4.0% of THAs performed in 2018. Patient and hospital characteristics including risk of mortality, geographic region, and teaching status were associated with increased utilization. Utilization of computer navigation was associated with increased hospital charges.

Abstract
BACKGROUND Opioids are commonly prescribed for postoperative pain following total joint arthroplasty. Despite widespread use, few studies have examined the dose-dependent effect of perioperative opioid use on postoperative complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Therefore, we examined the dose-dependent relationship between opioid use and postoperative complications following primary THA and TKA. METHODS We queried the Premier Healthcare Database to identify adult patients who underwent primary elective THA or TKA from 2004 to 2014, and quantified opioid consumption within the first 3 postoperative days. Opioid consumption was standardized to morphine milligram equivalents (MMEs). Patients were divided into quintiles on the basis of MME exposure: <54, 54 to 82, 83 to 116, 117 to 172, and >172 MMEs. Primary outcomes included postoperative periprosthetic joint infection, pulmonary embolism, deep venous thrombosis, and pulmonary complications. Secondary outcomes included wound infection, wound dehiscence, and readmission within 30 and 90 days postoperatively. Univariate and multivariate analyses were performed to compare differences between groups and to account for confounders. RESULTS A total of 1,525,985 patients were identified. The mean age was 65.7 ± 10.8 years, 598,320 patients (39.2%) were male, and 1,174,314 patients (77.0%) were Caucasian. On multiple logistic regression analysis, increasing MME exposure was associated with a dose-dependent increased risk of postoperative complications. Compared with patients receiving <54 MMEs, exposure to >172 MMEs was associated with greater odds of periprosthetic joint infection (adjusted odds ratio [aOR], 1.37; 95% confidence interval [CI], 1.33 to 1.42), deep venous thromboembolism (aOR, 1.34; 95% CI, 1.30 to 1.38), pulmonary embolism (aOR, 1.29; 95% CI, 1.25 to 1.34), and pulmonary complications (aOR, 1.06; 95% CI, 1.05 to 1.08). Exposure to >172 MMEs was associated with increased risk of wound infection (aOR, 1.37; 95% CI, 1.33 to 1.41), wound dehiscence (aOR, 1.24; 95% CI, 1.19 to 1.31), and readmission within 30 (aOR, 1.21; 95% CI, 1.20 to 1.22) and 90 days (aOR, 1.20; 95% CI, 1.19 to 1.21). CONCLUSIONS Increasing opioid use within the early postoperative period following THA or TKA was associated with a dose-dependent increased risk of periprosthetic joint infection and venous thromboembolic events.

Abstract
AIMS Robotic-assisted total knee arthroplasty (RA-TKA) is theoretically more accurate for component positioning than TKA performed with mechanical instruments (M-TKA). Furthermore, the ability to incorporate soft-tissue laxity data into the plan prior to bone resection should reduce variability between the planned polyethylene thickness and the final implanted polyethylene. The purpose of this study was to compare accuracy to plan for component positioning and precision, as demonstrated by deviation from plan for polyethylene insert thickness in measured-resection RA-TKA versus M-TKA. METHODS A total of 220 consecutive primary TKAs between May 2016 and November 2018, performed by a single surgeon, were reviewed. Planned coronal plane component alignment and overall limb alignment were all 0° to the mechanical axis; tibial posterior slope was 2°; and polyethylene thickness was 9 mm. For RA-TKA, individual component position was adjusted to assist gap-balancing but planned coronal plane alignment for the femoral and tibial components and overall limb alignment remained 0 ± 3°; planned tibial posterior slope was 1.5°. Mean deviations from plan for each parameter were compared between groups for positioning and size and outliers were assessed. RESULTS In all, 103 M-TKAs and 96 RA-TKAs were included. In RA-TKA versus M-TKA, respectively: mean femoral positioning (0.9° (SD 1.2°) vs 1.7° (SD 1.1°)), mean tibial positioning (0.3° (SD 0.9°) vs 1.3° (SD 1.0°)), mean posterior tibial slope (-0.3° (SD 1.3°) vs 1.7° (SD 1.1°)), and mean mechanical axis limb alignment (1.0° (SD 1.7°) vs 2.7° (SD 1.9°)) all deviated significantly less from the plan (all p < 0.001); significantly fewer knees required a distal femoral recut (10 (10%) vs 22 (22%), p = 0.033); and deviation from planned polyethylene thickness was significantly less (1.4 mm (SD 1.6) vs 2.7 mm (SD 2.2), p < 0.001). CONCLUSION RA-TKA is significantly more accurate and precise in planning both component positioning and final polyethylene insert thickness. Future studies should investigate whether this increased accuracy and precision has an impact on clinical outcomes. The greater accuracy and reproducibility of RA-TKA may be important as precise new goals for component positioning are developed and can be further individualized to the patient.

Abstract
STUDY DESIGN Retrospective comparative analysis of prospective cohort. OBJECTIVE To determine whether sacroiliac (SI) screw fixation ipsilateral to hand dominance compared to bilateral fixation impacts personal hygiene (wiping) after toileting. METHODS Inclusion criteria were adult spinal deformity (ASD) patients with long arthrodesis (≥T12-pelvis) who had undergone primary unilateral or bilateral SI fixation with a minimum of 2-years-follow-up. RESULTS 117 consecutive patients were included and separated into 2 groups: bilateral SI fixation (BL, n = 61) and unilateral SI fixation (UNI, n = 56), with no difference in age. Of UNI patients, 10.7% (6) performed personal hygiene with a different hand after surgery, compared to 6.6% (4) of patients who received BL fixation (P = 0.422). All UNI patients who switched hands were right-hand dominant, and 5/6 received right-sided fixation. There was no statistical difference found between number of levels fused (<8, 9-11, or >11 levels) and changes in personal hygiene habits. Over a third of patients from both groups had difficulty performing personal hygiene after fusion (UNI = 39.3% BL = 36.1%, P = 0.719). CONCLUSION SI screws increase the difficulty of performing personal hygiene; yet, the side of unilateral screws does not significantly change personal hygiene habits when compared to bilateral screw placement. Moreover, the length of the construct does not have a significant impact on ability to perform personal hygiene, cause changes in habits, or require the assistance of another individual. However, among our sample of individuals, bilateral fixation did result in a higher rate of revision instrumentation.

Abstract
BACKGROUND No previous systematic review has focused on the athletes who fail to return to sport after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). PURPOSE To review the literature on the athletes who fail to return to sport after hip arthroscopy for FAIS to determine the rate of nonreturning athletes and explore the reasons for their inability to return to sport after arthroscopic FAI surgery. STUDY DESIGN Systematic review and meta-analysis. METHODS Three electronic databases were searched for eligible articles. Two reviewers independently screened the titles, abstracts, and full-text articles using prespecified criteria. Eligible articles were those that clearly stated the rate of athletes who did not return to sport after hip arthroscopy for FAIS. Data collected were the rate of patients who did not return to sport, the level of competition (high level, recreational, or mixed), the type of sport, comments on patients who did not return to sport, the rate of subsequent hip surgeries (total hip replacement or revision hip arthroscopy) in nonreturning athletes, and the reported reason for not returning to sport. A random-effects model was used for meta-analysis. RESULTS Twenty studies were eligible for inclusion, and 1093 athletes were analyzed. The weighted rate of athletes who did not return to sport after hip arthroscopy for FAIS was 12.1% (95% CI, 7.7-17.4). Only 2 studies (2/20;10%) reported the age of the athletes who did not return, while sex was reported in 3 studies (3/20;15%). The estimated proportion of athletes who did not return to sport because of hip-related issues was significantly greater than the percentage of athletes who did not return for reasons unrelated to their hip (74.3% vs 22.3%; P < .0001). Persistent hip pain was the most commonly reported factor (52/110 patients; 47.2%) associated with failure to return to sport. Whether the nonreturning athletes underwent any subsequent hip procedure after hip arthroscopy for FAIS was reported in only 4 out of 20 studies (20%). There was evidence of publication bias and study heterogeneity. CONCLUSION The estimated rate of athletes who did not return to sport after hip arthroscopy for FAIS was 12%, with the majority of athletes being unable to return because of persistent hip pain. There is a severe lack of evidence on the athlete characteristics and clinical course of the nonreturning athletes, and the rate of subsequent hip procedures is unknown. The outcomes and reasons for athletes not returning to sport should be reported in detail to improve patient care.
