Abstract
BACKGROUND Controversy surrounds debridement, antibiotic and implant retention (DAIR) for treatment of acute periprosthetic joint infection (PJI). Data regarding DAIR's rate of infection resolution is variable with little investigation of functional outcomes. METHODS We identified 191 DAIR cases at a single institution from 2008 to 2020. Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) and Patient Reported Outcome Measurement Information System-10 (PROMIS) scores were collected. Patient Reported Outcome Scores were obtained from 60 cases. Median follow-up (IQR) was 4.5 (2.1 to 7.6) versus 3.0 (1.2 to 5.3) years for the control group. Mean scores were compared to a cohort of uncomplicated total knee arthroplasties matched by age, body mass index, and sex using generalized linear models adjusted for follow-up duration. Kaplan-Meier survivorship curves for PJI were constructed. RESULTS Mean Patient Reported Outcome Scores for the DAIR cohort were 57.2 ± 19.7 for KOOS-JR, 41.6 ± 7.1 for PROMIS physical health (PH), and 46.6 ± 8.7 for PROMIS mental health (MH). Mean control group values were 65.8 ± 21.0 for KOOS-JR, 44.6 ± 8.4 for PROMIS PH, and 49.2 ± 9.2 for PROMIS MH. No difference was observed in KOOS-JR (P = .83) or PROMIS MH (P = .11). PROMIS PH was lower in the DAIR cohort compared to the control group (P = .048). Median follow-up (years) for all 191 cases was 5.9 (range, 0.5 to 13.1). Survivorship (years) without subsequent operation for infection was 84% at 1, 82% at 2, and 79% at 5. CONCLUSION Knee and MH outcomes in successful DAIR procedures were similar to uncomplicated total knee arthroplasty. DAIR's success rate was 79% in treating acute PJI at 5 years. LEVEL OF EVIDENCE Level III.

Abstract
Background The COVID-19 pandemic has had a lasting impact on patients seeking total hip and knee arthroplasty (THA, TKA) including more patients undergoing same day discharge (SDD) following total joint arthroplasty (TJA). The purpose of this study was to assess whether expansion of SDD TJA during the COVID-19 pandemic resulted in more early complications following TJA. We anticipated that as many institutions quickly launched SDD TJA programs there may be an increase in 30-day complications. Methods We retrospectively queried the ACS-NSQIP database for all patients undergoing primary elective TJA from January 1, 2018, to December 31, 2020. Participants who underwent THA or TKA between January 1, 2018 and March 1, 2020 were grouped into pre-COVID and between March 1, 2020 and December 31, 2020 were grouped into post-COVID categories. Patients with length of stay greater than 0 were excluded. Primary outcome was any complication at 30 days. Secondary outcomes included readmission and re-operation 30 days. Results A total of 14,438 patients underwent TKA, with 9,580 occurring pre-COVID and 4,858 post-COVID. There was no difference in rates of total complication between the pre-COVID (3.55%) and post-COVID (3.99%) groups (p=0.197). Rates of readmissions for were similar for the pre-COVID (1.75%) and post-COVID (1.98%) groups (p=0.381). There was no statistically significant difference in respiratory complications between the pre-COVID (0.41%) and post-COVID group (0.23%, p=0.03). A total of 12,265 patients underwent THA, with 7,680 occurring pre-COVID and 4,585 post-COVID. There was no difference in rates of total complication between the pre-COVID (3.25%) and post-COVID (3.49%) groups (p=0.52). Rates of readmissions for were similar for the pre-COVID (1.77%) and post-COVID (1.68%) groups (p=0.381). There was no statistically significant difference in respiratory complications between the pre-COVID (0.16%) and post-COVID group (0.07%, p=0.26). Combined data to include THA and TKA patients did not find a statistical difference in the rate of complications or readmission but did note a decrease in the rate of combined respiratory complications in the post-COVID group (0.15% vs. 0.30%, p=0.028). Conclusion Rapid expansion of SDD TJA during the COVID-19 pandemic did not increase overall complication, readmission, or re-operation rates. Level of Evidence: IV.

Abstract
PURPOSE Ulnar variance (UV) is a radiographic measurement relating the articular surface heights of the distal radius and ulna. Abnormal UV increases the risk for wrist pathology; however, it only provides a static measurement of an inherently dynamic bony relationship that changes with wrist position and loading. The purpose of this study was to investigate how full-body weight-bearing affects UV using weight-bearing computed tomography (WBCT). METHODS Ten gymnasts completed two 45-second scans inside a WBCT machine while performing a handstand on a flat platform (H) and parallettes (P). A non-weight-bearing CT scan was collected to match clinical practice (N). Differences in UV between weight-bearing conditions were evaluated separately for dominant and nondominant sides, and then, UV was compared between weight-bearing conditions on pooled dominant/nondominant data. RESULTS Pooled analyses comparing weight-bearing conditions revealed a significant increase in UV for H versus N (0.58 mm) and P versus N (1.00 mm), but no significant change in UV for H versus P (0.43 mm). Significant differences in UV were detected for H versus N, P versus N, and H versus P for dominant and nondominant extremities. The change from N to H was significantly greater in the dominant versus nondominant side, but greater in the nondominant side from N to P. CONCLUSIONS Ulnar variance changed with the application of load and position of the wrist. Differences in UV were found between dominant and nondominant extremities. CLINICAL RELEVANCE Upper extremity loading patterns are affected by hand dominance as defined by a cartwheel and suggest skeletal consequences from repetitive load on a dominantly used wrist. Although statistically significant, subtle changes detected in this investigational study do not necessarily bear clinical significance. Future WBCT research can lead to improved diagnostic measures for wrist pathologies affected by active loading and rotational wrist behavior.

Abstract
BACKGROUND Prescription opioid abuse in the United States has risen substantially over the past 2 decades. Narcotic prescription refill restrictions may paradoxically be contributing to this epidemic. We investigated a novel, refill-based opioid prescription method to determine whether it would alter postoperative narcotic distribution or consumption. METHODS In this randomized controlled trial, patients undergoing internal fixation of distal radius fractures or thumb carpometacarpal joint arthroplasty received either a single prescription for all postoperative narcotics (control arm) or the same amount of pain medication divided into 3 equal prescriptions to be filled as needed (experimental arm). Outcomes included total narcotics dispensed, measured in morphine milligram equivalents (MME) through a prescription monitoring program, patient-reported opioid consumption versus opioid not consumed, and a satisfaction survey. RESULTS Forty-eight participants were enrolled; 25 were randomized to the control arm and 23 to the experimental arm. At 8 weeks post-op, fewer opioids had been dispensed to the experimental arm (177 ± 94 vs 287 ± 123 MME, P = .0025). At 6-week follow-up, the experimental arm reported lower narcotic consumption (124 ± 105 vs 214 ± 110 MME, P = .0131). Subanalysis of the independent surgeries yielded similar results. Some patients reported insurance issues when filling subsequent prescriptions. Consequently, although 100% of control arm patients reported good pain control, only 82.6% of experimental arm patients said likewise (P = .0455). CONCLUSIONS This randomized clinical trial demonstrated that patients obtained and consumed fewer narcotics when postoperative opioids were given in a refill-based prescription method. More research is needed to determine whether this opioid distribution method is reproducible, translatable, and feasible.

Abstract
Background The purpose of the present study was to investigate the relationship between socioeconomic status and Patient-Reported Outcomes Measurement Information System Global Health (PROMIS-GH) scores before and after primary total knee arthroplasty (TKA). We hypothesized that patients with greater social deprivation would have lower PROMIS-GH scores at 3 months and 1 year following primary TKA. Methods We retrospectively reviewed data from patients who underwent unilateral primary TKA and completed PROMIS-GH preoperatively and at 3 months (n = 257) or 1 year (n = 154) postoperatively. Area Deprivation Index (ADI), calculated from 9-digit zip codes, was used to measure social deprivation. Participants were grouped into quartiles by ADI score. Minimal clinically important difference in PROMIS-GH mental (PROMIS-MH) and physical health (PROMIS-PH) component scores were compared between ADI groups. Results Participants in the highest ADI quartile (most disadvantaged) had significantly lower PROMIS-MH and PROMIS-PH scores at every time point relative to the lowest ADI quartile (least disadvantaged) (P < .05 for all). Both ADI groups experienced significant improvements in PROMIS-PH following TKA (P < .001 for all), but not in PROMIS-MH (P > .05 for all) at 3-months and 1-year postoperatively. Magnitude of improvement in PROMIS-PH and rates of achievement of minimal clinically important difference did not significantly differ between ADI groups (P > .05 for all). Conclusions Socially disadvantaged patients benefit equally from primary TKA but are more likely to have persistently lower 1-year postoperative PROMIS-GH scores relative to less disadvantaged patients. Social deprivation should be accounted for when using PROMIS-GH to assess clinical outcomes for research and quality measures. Level of Evidence IV, retrospective cohort study.

Abstract
Optimization of perioperative analgesia has important implications for patient satisfaction and short-term outcomes. This study's purpose is to assess if preoperative gabapentin or intraoperative ketorolac influences postoperative pain or time to discharge following hip arthroscopy. In total, 409 patients who underwent hip arthroscopic femoroplasty and/or acetabuloplasty with a single surgeon for femoroacetabular impingement were retrospectively reviewed (September 2017 to February 2021). The effect of preoperative gabapentin or intraoperative ketorolac on postoperative visual analog scale (VAS) pain scores, perioperative opioids in morphine milligram equivalents (MMEs), time in post-anesthesia care unit (PACU), second-stage recovery and time to discharge was assessed using unadjusted and adjusted t-tests, and generalized linear models controlling for operative time, traction time, preoperative MME, intraoperative MME and postoperative MME were compared between the groups of gabapentin to no gabapentin and ketorolac to no ketorolac. There was no difference in first PACU VAS pain score, final PACU VAS score, VAS pain score prior to discharge, average VAS pain score or pain level on follow-up call in the unadjusted or adjusted analysis for the preoperative gabapentin or intraoperative ketorolac groups. Females had higher first PACU VAS pain score (6.05 versus 5.15 P = 0.0026), final PACU VAS pain score (4.43 versus 3.90, P = 0.0045), final VAS pain score prior to discharge (3.87 versus 3.03, P < 0.001) and average postoperative pain score (4.60 versus 4.03, P < 0.001), but no difference in VAS pain score on follow-up call following surgery. Gabapentin or ketorolac was not associated with decreased VAS pain scores or time to discharge after hip arthroscopy.

Abstract
Background The purpose of this study was to develop projections of the prevalence of obesity in aseptic revision THA and TKA patients through the year 2029. Methods The National Surgical Quality Improvement Project (NSQIP) was queried for years 2011-2019. Current procedural terminology (CPT) codes 27134, 27137, and 27138 were used to identify revision THA and CPT codes 27486 and 27487 were used to identify revision TKA. Revision THA/TKA for infectious, traumatic, or oncologic indications were excluded. Participant data were grouped according to body mass index (BMI) categories: underweight/normal weight, <25 kg/m2; overweight, 25-29.9 kg/m2; class I obesity, 30.034.9 kg/m2; class II obesity, 35.0-39.9 kg/m2; morbid obesity ≥ 40 kg/m2. Prevalence of each BMI category was estimated from year 2020 to year 2029 through multinomial regression analyses. Results 38,325 cases were included (16,153 revision THA and 22,172 revision TKA). From 2011 to 2029, prevalence of class I obesity (24% to 25%), class II obesity (11% to 15%), and morbid obesity (7% to 9%) increased amongst aseptic revision THA patients. Similarly, prevalence of class I obesity (28% to 30%), class II obesity (17% to 29%), and morbid obesity (16% to 18%) increased in aseptic revision TKA patients. Conclusion Prevalence of class II obesity and morbid obesity demonstrated the largest increases in revision TKA and THA patients. By 2029, we estimate that approximately 49% of aseptic revision THA and 77% of aseptic revision TKA will have obesity and/or morbid obesity. Resources aimed at mitigating complications in this patient population are needed. Level of Evidence: III.

Abstract
Background Food insecurity is an increasingly recognized public health issue. Identifying risk factors for food insecurity would support public health initiatives to provide targeted nutrition interventions to high-risk individuals. Food insecurity has not been investigated in the orthopedic trauma population. Methods From April 27, 2021 to June 23, 2021, we surveyed patients within six months of operative pelvic and/or extremity fracture fixation at a single institution. Food insecurity was assessed using the validated United States Department of Agriculture Household Food Insecurity questionnaire generating a food security score of 0 to 10. Patients with a food security score ≥ 3 were classified as Food Insecure (FI) and patients with a food security score < 3 were classified as Food Secure (FS). Patients also completed surveys for demographic information and food consumption. Differences between FI and FS for continuous and categorical variables were evaluated using the Wilcoxon sum rank test and Fisher's exact test, respectively. Spearman's correlation was used to describe the relationship between food security score and participant characteristics. Logistic regression was used to determine the relationship between patient demographics and odds of FI. Results We enrolled 158 patients (48% female) with a mean age of 45.5 ± 20.3 years. Twenty-one patients (13.3%) screened positive for food insecurity (High security: n=124, 78.5%; Marginal security: n=13, 8.2%; Low security: n=12, 7.6%; Very Low security: n=9, 5.7%). Those with a household income level of ≤ $15,000 were 5.7 times more likely to be FI (95% CI 1.8-18.1). Widowed/single/divorced patients were 10.2 times more likely to be FI (95% CI 2.3-45.6). Median time to the nearest full-service grocery store was significantly longer for FI patients (t=10 minutes) than for FS patients (t=7 minutes, p=0.0202). Age (r= -0.08, p=0.327) and hours working (r= -0.10, p=0.429) demonstrated weak to no correlation with food security score. Conclusion Food insecurity is common in the orthopedic trauma population at our rural academic trauma center. Those with lower household income and those living alone are more likely to be FI. Multicenter studies are warranted to evaluate the incidence and risk factors for food insecurity in a more diverse trauma population and to better understand its impact on patient outcomes.

Abstract
BACKGROUND Patient self-assessment of knee function in end-stage osteoarthritis (OA) and following total knee arthroplasty (TKA) using patient-reported outcome measures (PROMs) has become standard for defining disability. The relationship of PROMs to functional performance requires a continued investigation. The purpose of this study was to determine correlations between patient demographics, PROMs, and functional performances using a marker-less image capture system (MICS). METHODS Patients indicated for elective TKA completed the Knee Injury and Osteoarthritis Score for Joint Replacement (KOOS-JR) and an office-based functional assessment using a MICS. Patient age, body mass index (BMI), and gender were collected. A total of 112 patients were enrolled. Their mean age was 65.0 (±9.7) years, mean BMI was 32.5 (±6.6) kg/m2, and mean KOOS-JR was 14.5 (±5.7). The relationships between patient characteristics, KOOS-JR, MICS Alignment (coronal), MICS Mobility (flexion), and composite Total Joint scores were described using Spearman's correlation coefficients. RESULTS BMI was weakly correlated with KOOS-JR (ρ = -0.22, P = .024), whereas age was not. Age and BMI were not correlated with performance scores. There were weak to no correlations between KOOS-JR and MICS Alignment (ρ = -0.01, P = .951), Mobility (ρ = 0.33, P < .001), and Total Joint scores (ρ = 0.06, P = .504). CONCLUSION This study found no strong correlation between KOOS-JR and functional performance using a validated MICS for patients with end-stage knee OA. Further study is warranted in determining the relationship between PROMs and performance to optimize outcomes of patients undergoing nonoperative or surgical interventions for knee OA. The use of high-fidelity functional assessment tools that can be integrated into clinical workflow, such as the MICS used in this study, should permit PROM/functional performance comparisons in large populations.

Abstract
Hip dysplasia is known to lead to premature osteoarthritis. Computational models of joint mechanics have documented elevated contact stresses in dysplastic hips, but elevated stress has not been directly associated with regional cartilage degeneration. The purpose of this study was to determine if a relationship exists between elevated contact stress and intra-articular cartilage damage in patients with symptomatic dysplasia and femoroacetabular impingement. Discrete element analysis was used to compute hip contact stresses during the stance phase of walking gait for 15 patients diagnosed with acetabular dysplasia and femoral head-neck offset deformity. Contact stresses were summed over the duration of the walking gait cycle and then scaled by patient age to obtain a measure of chronic cartilage contact stress exposure. Linear regression analysis was used to evaluate the relationship between contact stress exposure and cartilage damage in each of six acetabular subregions that had been evaluated arthroscopically for cartilage damage at the time of surgical intervention. A significant correlation (R2 = 0.423, p < 0.001) was identified between chondromalacia grade and chronic stress-time exposure above both a 1 MPa damage threshold and a 2 MPa-years accumulated damage threshold. Furthermore, an over-exposure threshold of 15% regional contact area exceeding the 1 and 2 MPa-years threshold values resulted in correct identification of cartilage damage in 83.3% (55/66) of the acetabular subregions loaded during gait. These results suggest corrective surgery to alleviate impingement and reduce chronic contact stress exposures below these damage-inducing thresholds could mitigate further cartilage damage in patients with hip dysplasia.

Abstract
BACKGROUND The use of claims databases for research after total hip and knee arthroplasty (THA, TKA) has increased exponentially. These studies rely on accurate coding, and inadvertent inclusion of patients with nonroutine indications may influence results. The purpose of this study was to evaluate the complexity of THA and TKA captured by CPT code and determine if complication rates vary based on the indication. METHODS The NSQIP database was queried using CPT codes 21730 and 27447 to identify patients undergoing THA and TKA from 2018 to 2019. The surgical indication was classified based on the ICD-10 diagnosis code as routine primary, complex primary, inflammatory, fracture, oncologic, revision, infection, or indeterminant. Patient factors and 30-day complications, readmission, reoperation, and wound complications were compared. RESULTS A total of 86,009 THA patients had 703 ICD-10 diagnosis codes and 91.4% were routine primary indications. Complication rates were: routine primary 7.4%, complex primary 11.3%, inflammatory 12.5%, fracture 23.9%, oncologic 32.4%, revision 26.9%, infection 38.7%, and indeterminant 10.3% (P < .0001). 137,500 TKA patients had 552 ICD-10 diagnosis codes and 96.1% were routine primary cases. Complication rates were: routine primary 5.9%, complex primary 8.0%, inflammatory 7.2%, fracture 38.9%, oncologic 32.7%, revision 13.3%, infection 37.7%, and indeterminant 9.6% (P < .0001). Routine primary arthroplasty had significantly lower rates of reoperation, readmission, and wound complications. CONCLUSION Using CPT code alone captures 10% of THA and 4% of TKA patients with procedures for nonroutine primary indications. It is essential to recognize identification of patients simply by CPT code has the potential to inadvertently introduce bias, and surgeons should critically assess methods used to define the study populations.

Abstract
BACKGROUND The purpose of this study was to perform a systematic review and meta-analysis on the association between operative time and peri-prosthetic joint infection (PJI) after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS PubMed, Embase, and Cochrane CENTRAL databases were searched for relevant articles dating 2000-2020. Relationship of operative time and PJI rate in primary total joint arthroplasty (TJA) was evaluated by pooled odds ratios (OR) and 95% confidence intervals. RESULTS Six studies were identified for meta-analysis. TJA lasting greater than 120 minutes had greater odds of PJI (OR, 1.63 [1.00-2.66], p=0.048). Similarly, there were greater odds of PJI for TJA procedures lasting greater than 90 minutes (OR, 1.65 [1.27-2.14]; p<0.001). Separate analyses of TKA (OR, 2.01 [0.76-5.30]) and THA (OR, 1.06 [0.80-1.39]) demonstrated no difference in rates of PJI in cases of operative time ≥ 120 minutes versus cases < 120 minutes (p>0.05 for all). Using any surgical site infection (SSI) as an endpoint, both TJA (OR, 1.47 [1.181.83], p<0.001) and TKA (OR, 1.50 [1.08-2.08]; p=0.016) procedures lasting more versus less than 120 minutes demonstrated significantly higher odds of SSI. CONCLUSION Following TJA, rates of SSI and PJI are significantly greater in procedures ≥120 minutes in duration relative to those < 120 minutes. When analyzing TKA separately, higher rates of SSI were observed in procedures ≥ 120 minutes in duration relative to those <120 minutes. Rates of PJI in TKA or THA procedures alone were not significantly impacted by operative time. Level of Evidence: V.

Abstract
BACKGROUND Incidence of blood transfusions after primary and revision total hip and knee arthroplasty (primary total hip arthroplasty [pTHA], revision THA [rTHA], primary total knee arthroplasty [pTKA], and revision TKA [rTKA]) has been decreasing for a multitude of reasons. The purpose of this study was to assess whether transfusion rates have continued to decline and evaluate patient factors associated with transfusions. METHODS The American College of Surgeons National Surgical Quality Improvement Program was queried to identify patients undergoing pTHA, pTKA, rTHA, and rTKA between 2011 and 2019. Patients undergoing bilateral procedures and arthroplasty for fracture, infection, or tumor were excluded. Trends in blood transfusions were assessed. Patient factor association with blood transfusions was evaluated using 2018 and 2019 data. RESULTS Transfusion rates decreased from 21.4% in 2011 to 2.5% in 2019 for pTHA (P < .0001). For pTKA, transfusion rates declined from 17.6% to 0.7% (P < .0001). In rTHA, the transfusion rate decreased from 33.5% to 12.0% from 2011 to 2019 (P < .0001). Transfusion rates declined from 19.4% to 2.6% for rTKA during the study period (P < .0001). Transfusions were more frequent in patients who were older, female, with more comorbidities, with lower hematocrit, receiving nonspinal anesthesia, and with longer operative time. Lower preoperative hematocrit, history of bleeding disorders, and preoperative transfusion were associated with greater odds for postoperative transfusion after multivariate analysis. CONCLUSION Transfusions after both primary and revision total joint arthroplasty have continued to decrease. Studies of arthroplasty complications should account for decreasing transfusions when assessing overall complication rates. Future studies should consider interventions to further reduce transfusions in revision arthroplasty.

Abstract
BACKGROUND While muscle atrophy is a function of normal aging, loss of muscle in the setting of hip and knee osteoarthritis (OA) has been observed using radiographic studies. There is limited data available regarding changes in extremity composition using bioimpedance (BIA). The purpose of this study was to assess the changes in extremity composition in patients with isolated, unilateral hip or knee OA using BIA. METHODS Patients presenting to our institution's adult reconstruction clinic from February 2020 to April 2021 were retrospectively reviewed to identify those with isolated, unilateral hip and knee OA. The InBody 770 Body Composition Analyzer (InBody USA, Cerritos, California) was used to perform a complete body composition assessment, per protocol. Lean extremity mass (LEM), fat mass (FM), intracellular water (ICW), extremity body water (EBW = ICW + extracellular water (ECW)) and phase angle (PA) were determined. Differences between the affected (OA) and unaffected (no OA) extremities were compared using t-tests. RESULTS 38 patients had isolated hip OA. The mean age was 60.8 (±11.7) years, mean BMI was 31.7 (±6.8) kg/m2, and 39.5% were female. LEM, FM, EBW, ICW, and PA were significantly decreased in the hip OA extremity (LEM: 20.0 vs. 20.4 kg, p=0.0008, FM: 8.8 vs. 8.9 kg, p=0.0049, EBW: 15.7 vs 16.0, p=0.0011, ICW: 9.5 vs. 9.7 L, p=0.0004, PA: 4.5 vs 4.9º, p<0.0001). There were 25 patients with isolated knee OA. Mean age was 62.8 (±11.3) years, mean BMI was 33.6 (±6.9) kg/m2, and 52.0% were female. FM and PA were significantly lower in the knee OA extremity (11.3 vs 11.4 kg, p=0.0291, 4.5 vs 4.9º, p<0.0001). There were no significant differences in LEM, EBW, and ICW between the knee OA extremity and the unaffected extremity. CONCLUSION Patients with isolated, unilateral hip OA had decreased LEM, FM, EBW, and ICW in the affected extremity. Both unilateral hip and knee OA was associated with decreased PA, suggestive of greater underlying dysfunction in muscle or cellular performance. Further study is needed to better define when these abnormalities develop, how they progress over time, and the impact of targeted interventions in reversing these changes. Level of Evidence: III.

Abstract
BACKGROUND Changes in body composition, especially loss of lean mass, commonly occur in the orthopedic trauma population due to physical inactivity and inadequate nutrition. The purpose of this study was to assess inter-rater and intra-rater reliability of a portable bioelectrical impedance analysis (BIA) device to measure body composition in an orthopedic trauma population after operative fracture fixation. BIA uses a weak electric current to measure impedance (resistance) in the body and uses this to calculate the components of body composition using extensively studied formulas. METHODS Twenty subjects were enrolled, up to 72 hours after operative fixation of musculoskeletal injuries and underwent body composition measurements by two independent raters. One measurement was obtained by each rater at the time of enrollment and again between 1-4 hours after the initial measurement. Reliability was assessed using intraclass correlation coefficients (ICC) and minimum detectable change (MDC) values were calculated from these results. RESULTS Inter-rater reliability was excellent with ICC values for body fat mass (BFM), lean body mass (LBM), skeletal muscle mass (SMM), dry lean mass (DLM), and percent body fat (PBF) of 0.993, 0.984, 0.984, 0.979, and 0.986 respectively. Intra-rater reliability was also high for BFM, LBM, SMM, DLM, and PBF, at 0.994, 0.989, 0.990, 0.983, 0.987 (rater 1) and 0.994, 0.988, 0.989, 0.985, 0.989 (rater 2). MDC values were calculated to be 4.05 kg for BFM, 4.10 kg for LBM, 2.45 kg for SMM, 1.21 kg for DLM, and 4.83% for PBF. CONCLUSION Portable BIA devices are a versatile and attractive option that can reliably be used to assess body composition and changes in lean body mass in the orthopedic trauma population for both research and clinical endeavors.

Abstract
BACKGROUND Postoperative complications and substantial loss of physical function are common after musculoskeletal trauma. We conducted a prospective randomized controlled trial to assess the impact of conditionally essential amino acid (CEAA) supplementation on complications and skeletal muscle mass in adults after operative fixation of acute fractures. METHODS Adults who sustained pelvic and extremity fractures that were indicated for operative fixation at a level-I trauma center were enrolled. The subjects were stratified based on injury characteristics (open fractures and/or polytrauma, fragility fractures, isolated injuries) and randomized to standard nutrition (control group) or oral CEAA supplementation twice daily for 2 weeks. Body composition (fat-free mass [FFM]) was measured at baseline and at 6 and 12 weeks postoperatively. Complications were prospectively collected. An intention-to-treat analysis was performed. The relative risk (RR) of complications for the control group relative to the CEAA group was determined, and linear mixed-effects models were used to model the relationship between CEAA supplementation and changes in FFM. RESULTS Four hundred subjects (control group: 200; CEAA group: 200) were enrolled. The CEAA group had significantly lower overall complications than the control group (30.5% vs. 43.8%; adjusted RR = 0.71; 95% confidence interval [CI] = 0.55 to 0.92; p = 0.008). The FFM decreased significantly at 6 weeks in the control subjects (-0.9 kg, p = 0.0205), whereas the FFM was maintained at 6 weeks in the CEAA subjects (-0.33 kg, p = 0.3606). This difference in FFM was not seen at subsequent time points. CONCLUSIONS Our results indicate that CEAA supplementation has a protective effect against common complications and early skeletal muscle wasting after operative fixation of extremity and pelvic fractures. Given the potential benefits of this inexpensive, low-risk intervention, multicenter prospective studies in focused trauma populations are warranted. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
BACKGROUND Obesity is associated with higher rates of adverse outcomes following primary total hip arthroplasty (THA). The purpose of this study is to utilize 3 national databases to develop projections of obesity within the general population and primary THA patients in the United States through 2029. METHODS Data from the National Surgical Quality Improvement Program (NSQIP), the Behavior Risk Factor Surveillance System (BRFSS), and the National Health and Nutrition Examination Survey were queried for years 1999-2019. Current Procedural Terminology code 27130 was used to identify primary THA patients in NSQIP. Individuals were categorized according to body mass index (kg/m2) by year: normal weight (≤24.9); overweight (25.0-29.9); obese (30.0-39.9); and morbidly obese (≥40). Multinomial logistic regression was used to project categorical body mass index data for years 2020-2029. RESULTS A total of 8,222,013 individuals were included (7,986,414 BRFSS, 235,599 NSQIP THA). From 2011 to 2019, the prevalence of normal weight and overweight individuals declined in the general population (BRFSS) and in primary THA. Prevalence of obese/morbidly obese individuals increased in the general population from 31% to 36% and in primary THA from 42% to 49%. Projection models estimate that by 2029, 46% of the general population will be obese/morbidly obese and 55% of primary THA will be obese/morbidly obese. CONCLUSION By 2029, we estimate ≥55% of primary THA to be obese/morbidly obese. Increased resources dedicated to care pathways and research focused on improving outcomes in obese arthroplasty patients will be necessary as this population continues to grow.

Abstract
ABSTRACT
The Femoro-Epiphyseal Acetabular Roof (FEAR) index is a newer measurement to identify the hip instability with borderline acetabular dysplasia. The purpose of this study is to (i) validate the FEAR index in determining the stability of the hip in patients who have previously been treated surgically for femoroacetabular impingement (FAI) and/or developmental dysplasia of the hip (DDH) and (ii) to examine the relationship between the FEAR index and femoral version, lateral center edge angle, Tönnis angle and alpha angle (AA). Patient demographics and radiographic measurements of 215 hips (178 patients), 116 hips treated with hip arthroscopy for FAI and 99 hips treated with periacetabular osteotomy (PAO) for DDH were compared between groups. The sensitivity and specificity of the FEAR index to detect the surgical procedure performed (PAO or hip arthroscopy) was calculated, and a threshold value was proposed. Pearson’s correlation coefficients were used to describe the relationships between the FEAR index, femoral version and other radiographic measurements. The FEAR index was higher in patients with DDH versus FAI (DDH: 2.81 ± 0.50° versus FAI: −1.00 ± 0.21°, P < 0.001). A FEAR index threshold value of 3° had a sensitivity and specificity of 80% and 81%, respectively, for correctly predicting the surgical procedure performed. Femoral version was positively associated with the FEAR index in the setting of DDH (r = 0.36, P = 0.001) but not FAI (r = 0.02, P = 0.807). A FEAR index of 3° predicted treatment with 80% sensitivity and 81% specificity. In addition, femoral version significantly correlates with the FEAR index in the setting of DDH but not FAI.

Abstract
The effects of smoking on unicompartmental knee arthroplasty (UKA) are unknown. The purpose of this study was to evaluate the effects of smoking on short-term outcomes following primary UKA. A query of the National Surgical Quality Improvement Project (NSQIP) database was used to identify cases of primary UKA performed during years 2006 to 2017. Patient demographics, operative times, and postoperative complications were compared between smoking and nonsmoking cohorts. Descriptive statistics, univariate analyses, and multivariate analyses were conducted to evaluate the effects of smoking on primary UKA. A total of 10,593 cases of UKA were identified; 1,046 of these patients were smokers. Univariate analysis demonstrated smokers to have higher rates of any complication (4.6 vs. 3.3%, p = 0.031), any wound complication (1.82 vs. 0.94%, p = 0.008), deep wound infection (0.57 vs. 0.13%, p = 0.006), and reoperation (1.34 vs. 0.68%, p = 0.018) relative to nonsmokers. Multivariate analysis demonstrated smokers to have higher rates of any wound complication (odds ratio [OR] = 1.79; 95% confidence interval [CI]: 1.06-2.95) and reoperation (OR = 2.11; 95% CI: 1.12-3.97). Smokers undergoing primary UKA are at higher risk for any wound complication and reoperation relative to nonsmokers in the first 30 days postoperatively. Further studies evaluating the long-term effects of smoking on outcome following UKA, as well as the impact of smoking cessation on outcomes following UKA, are needed.

Abstract
PURPOSE To compare postoperative pain and recovery after anterior cruciate ligament reconstruction (ACLR) in patients who received an adductor canal block (ACB) or periarticular local infiltrative anesthesia (LIA). METHODS A retrospective review of a prospectively collected ACL registry was performed. Patients underwent ACLR at a single institution between January 2015 and September 2020 and received long-acting local anesthesia with a preoperative ultrasound-guided ACB or periarticular LIA after surgery. Visual analog scale (VAS) pain scores, milligram morphine equivalents (MME) consumed in the post-anesthesia care unit (PACU), and total hospital recovery time were compared. Univariate analysis was used to compare VAS pain and MME totals between overall groups and groups propensity score matched for age, sex, body mass index, graft type, and meniscal treatment. Results are presented as mean (95%CI) unless otherwise indicated. RESULTS There were 265 knees (253 patients) included (LIA, 157 knees; ACB, 108 knees). Overall, VAS pain scores before hospital discharge (LIA: 2.6 [2.4-2.8] vs ACB: 2.4 [2.1-2.7]; P = .334) and total MMEs were similar (LIA: 17.6 [16.4-18.8] vs ACB: 18.5 [17.2-19.8] (MME); P =.134). Median time to discharge also did not significantly differ (LIA: 137.5 [IQR: 116-178] vs. ACB: 147 [IQR: 123-183] (min); P = .118). Matched subanalysis (LIA and ACB; n = 94) did not reveal significant differences in VAS pain before discharge (LIA: 2.4 [2.1-2.7] vs ACB: 2.7 [2.4-3.0]; P = .134) or total MMEs (LIA: 18.6 (17.2-20.0) vs ACB: 17.9 (16.4-19.4); P = .520). CONCLUSION The use of ACB or LIA resulted in similar early pain levels, opioid consumption, and hospital recovery times after ACLR surgery. LEVEL OF EVIDENCE III, retrospective comparison study.

Abstract
BACKGROUND Body mass index (BMI) cutoffs are commonly used to decide whether to offer obese patients elective total knee arthroplasty (TKA). However, weight loss goals may be unachievable for many patients who are consequentially denied complication-free surgery. The purpose of this study was to assess the impact of different BMI cutoffs on the rates of complication-free surgery after TKA. METHODS Patients undergoing elective, primary TKA from 2015 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program database using Common Procedural Terminology code 27447. The BMI and rates of any thirty-day complication were collected. BMI cutoffs of 30, 35, 40, 45, and 50 kg/m2 were applied to model the incidence of complications if TKA would have been allowed or denied based on the BMI. RESULTS A total of 314,719 patients underwent TKA, and 46,386 (14.7%) had a BMI ≥40 kg/m2. With a BMI cutoff of 40 kg/m2, 268,333 (85.3%) patients would have undergone TKA. A total of 282,552 (94.8%) would experience complication-free surgery, and 17.3% of all complications would be prevented. TKA would proceed for 309,479 (98.3%) patients at a BMI cutoff of 50 kg/m2. A total of 293,108 (94.7%) would not experience a complication, and 2.8% of complications would be prevented. A BMI cutoff of 35 kg/m2 would prevent 36.6% of all complications while allowing 94.8% of complication-free surgeries to proceed. CONCLUSION Lower BMI cutoffs can reduce complications, but will limit access to complication-free TKA for many patients. These data do not indicate TKA should be performed without consideration of risks from obesity; however, a holistic assessment and shared decision-making may be more valuable when deciding on appropriate goal weight reduction.

Abstract
BACKGROUND Morbidly obese patients have increased rates of complications following primary total hip arthroplasty (THA) and it is not clear whether improvements in THA care pathways are equally benefitting these patients. The purpose of this study is to assess if reductions in complications have similarly improved for both morbidly obese and non-morbidly obese patients after THA. METHODS Patients undergoing primary THA between 2011 and 2019 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Patients were stratified by body mass index (BMI) <40 and ≥40 kg/m2. Thirty-day rates of infectious complications, readmissions, reoperation, and any complication were assessed. Trends in complications were compared utilizing odds ratios and multivariate analyses. RESULTS In total, 234,334 patients underwent THA and 16,979 (7.8%) had BMI ≥40 kg/m2. Patients with BMI ≥40 kg/m2 were at significantly higher odds for readmission, reoperation, and infectious complications. Odds for any complication were lower for morbidly obese patients in 2011, not different from 2012 to 2014, and higher from 2015 to 2019 compared to lower BMI patients. Odds for any non-transfusion complication were higher for morbidly obese patients and there was no improvement for either group over the study period. There were improvements in rates of readmission and reoperation for patients with BMI <40 kg/m2 and readmission for BMI >40 kg/m2. CONCLUSION Odds for readmission and reoperation for non-morbidly obese patients and readmission for morbidly obese patients improved from 2011 to 2019. Reductions in transfusions are largely responsible for improvements in overall complication rates. Although morbidly obese patients remain at higher risk for complications, there does not appear to be a growing disparity in outcomes between morbidly obese and non-morbidly obese patients.

Abstract
An updated understanding of unicompartmental knee arthroplasty (UKA) utilization is needed. The purpose of this study was to evaluate temporal trends in volume and utilization of UKA among early-career surgeons and to examine the influence of fellowship training status on utilization of UKA. The American Board of Orthopaedic Surgery (ABOS) Part-II database was queried from 2010 to 2019 to identify candidates who reported ≥1 total knee arthroplasty (TKA) or UKA. Self-reported history of fellowship training experiences was recorded. "High-volume" surgeons were defined as performing ≥7 UKA over the ABOS Part-II collection period. Trends were evaluated with the Cochrane-Armitage test and generalized linear models. From 2010 to 2019, a total of 2,045 candidates (28.1%) reported ≥1 TKA, while 585 candidates (8.0%) reported ≥1 UKA. The number of candidates reporting ≥1 UKA significantly increased (p = 0.001). An increase in UKA volume was observed over the study period (p < 0.001). Rates of utilization of UKA relative to TKA did not change significantly over the study period (p = 0.11). Sixty-three (2.4%) candidates met the study definition for high-volume UKA utilization. UKA procedure volume increased among ABOS Part-II candidates over the study period; however, rates of UKA utilization relative to TKA volume remained unchanged. Increasing volume of UKA performed by early-career surgeons is likely secondary to an increased number of surgeons trained in adult reconstruction. Only 2.4% of candidates who reported performing at least one knee arthroplasty procedure met the threshold for a high-volume UKA practice. Early-career surgeons should remain conscientious of UKA volume in their practice.

Abstract
OBJECTIVE The purpose of this study was to examine associations between level of kinesiophobia and improvement in physical function during recovery from lower extremity injury. METHODS A total 430 adults (mean [SD]: age = 27.3 [6.4] years; sex = 70.5% men; body mass index = 27.6 [5.2] kg/m2) were included in the analyses. Using the Patient-Reported Outcomes Measurement Information System, physical function was evaluated in parallel with treatment from a physical therapist at the initial visit and every 3 weeks until final visit or up to 6 months. A Tampa Scale of Kinesiophobia (TSK-17) score of >41 indicated elevated TSK. Four TSK groups were identified: (1) TSK score improved from >41 at initial visit to <41 by final visit (TSK_I), (2) TSK score was <41 at initial and final visits (TSK-), (3) TSK score was >41 at initial and final visits (TSK+), and (4) TSK score worsened from <41 at initial visit to ≥41 by final visit (TSK_W). Linear mixed effects models were used to examine differences between groups in improved physical function over time, with adjustment for depression and self-efficacy. RESULTS Groups with elevated kinesiophobia at the final visit had smaller positive improvements in physical function (mean change [95% CI]: TSK+ = 7.1 [4.8-9.4]; TSK_W: 6.0 [2.6-9.4]) compared with groups without elevated kinesiophobia at the final visit (TSK_I = 9.8 [6.4-13.3]; TSK- = 9.7 [8.1-11.3]) by 12 weeks. CONCLUSIONS Elevated kinesiophobia that persists or develops over the course of care is associated with less improvement in physical function within military and civilian cohorts. IMPACT The findings of this prospective longitudinal study support the need to assess for elevated kinesiophobia throughout the course of care because of its association with decreased improvement in physical function. LAY SUMMARY To help improve your physical function, your physical therapist can monitor the interaction between fear of movement and your clinical outcomes over the course of treatment.

Abstract
PURPOSE To compare postoperative pain and early recovery after hip arthroscopy with and without a perineal post for joint distraction. METHODS We retrospectively reviewed a consecutive series of patients who underwent hip arthroscopy before and after the adoption of a postless technique. Patients who underwent concurrent periacetabular or femoral osteotomy were excluded. Demographic information, procedure variables, and visual analog scale (VAS) pain scores were recorded. Analgesic medications given were converted to morphine milligram equivalents (MME) for comparison. Uni- and multivariate analyses were conducted to compare total MME, postoperative pain, and time to discharge between groups. RESULTS One hundred patients were in each group. The overall age (mean ± standard deviation) was 26.5 ± 9.9 years (Post [P]: 57 females; No Post [NP]: 68 females). Total operative time (P 100.4 ± 17.9 minutes vs NP 89.1 ± 25.5 minutes, P = .0004), traction time (P 45.8 ± 10.3 minutes vs NP 40.9 ± 11.1 minutes, P = .0017), and operating room time (P 148.8 ± 19.3 minutes vs NP 137.3 ± 25.8 minutes, P = .0005) were found to be shorter in the NP group. Total MME, and final VAS pain scores in the PACU were similar between both groups (MME, P = .1620; VAS, P = .2139). Time to discharge was significantly shorter in the NP group (P 207.2 ± 58.8 vs NP 167.5 ± 47.9, P < .0001). Patient age (≥25 years) (65.2 ± 18.1 vs 59.8 ± 15.7 [MME], P = .0269) and elevated body mass index (≥25) (65.1 ± 17.1 vs 59.3 ± 16.4 [MME], P = .0164) were factors associated with greater total MME consumption. Female sex was associated with higher postoperative VAS pain scores (FM 4.1 ± 1.6 vs M 3.4 ± 1.8 P = .0027). CONCLUSIONS Adoption of the postless technique did not result in prolonged operating room or operative time. Overall, both groups had similar postoperative pain, however, the time from surgery to hospital discharge was shorter in the postless group. LEVEL OF EVIDENCE III, retrospective comparison study.

Abstract
BACKGROUND Extended oral antibiotic prophylaxis after primary total knee arthroplasty (TKA) and total hip arthroplasty (THA) in patients with body mass index (BMI) ≥40 kg/m2 may reduce the rate of early periprosthetic joint infection (PJI); however, existing data are limited. The purpose of this study was to examine rates of wound complications and PJI in patients with BMI ≥40 kg/m2 treated with and without extended oral antibiotic prophylaxis after surgery. METHODS We retrospectively identified all primary THA and TKA performed since 2015 in patients with a BMI ≥40 kg/m2 at a single institution. Extended oral antibiotic prophylaxis for 7-14 days after surgery was prescribed at the discretion of each surgeon. Wound complications and PJI were examined at 90 days postoperatively. RESULTS In total, 650 cases (205 THA and 445 TKA) were analyzed. Mean age was 58 years and 62% were women. Mean BMI was 44 kg/m2. Extended oral antibiotic prophylaxis was prescribed in 177 cases (27%). At 90 days, there was no difference between prophylaxis and nonprophylaxis groups in rate of wound complications (11% vs 8%; P = .41) or PJI (1.7% vs 0.6%; P = .35). The univariate analysis demonstrated increased operative time (odds ratio (OR) 1.01; 95% confidence interval (95% CI) 1.01-1.02) and diabetes mellitus (OR 1.88; 95% CI 1.03-3.46) to be associated with increased risk of 90-day wound complications. No patient factors were associated with increased risk of PJI at 90 days postoperatively. CONCLUSION Extended oral antibiotic prophylaxis after primary THA and TKA did not reduce rates of wound complications or early PJI in a morbidly obese patient population.

Abstract
BACKGROUND Arthroscopic shoulder capsulolabral repair using glenoid-based suture anchor fixation provides consistently favorable outcomes for patients with anterior glenohumeral instability. To optimize outcomes, inferior anchor position, especially at the 6-o'clock position, has been emphasized. Proponents of both the beach-chair (BC) and lateral decubitus (LD) positions advocate that this anchor location can be consistently achieved in both positions. HYPOTHESIS Patient positioning would be associated with the surgeon-reported labral tear length, total number of anchors used, number of anchors in the inferior glenoid, and placement of an anchor at the 6-o'clock position. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS This study was a cross-sectional analysis of a prospective multicenter cohort of patients undergoing primary arthroscopic anterior capsulolabral repair. Patient positioning in the BC versus LD position was determined by the operating surgeon and was not randomized. At the time of operative intervention, surgeon-reported labral tear length, total anchor number, anchor number in the inferior glenoid, and anchor placement at the 6-o'clock position were evaluated between BC and LD cohorts. Descriptive statistics and between-group differences (continuous: t test [normal distributions], Wilcoxon rank sum test [nonnormal distributions], and chi-square test [categorical]) were assessed. RESULTS In total, 714 patients underwent arthroscopic anterior capsulolabral repair (BC vs LD, 406 [56.9%] vs 308 [43.1%]). The surgeon-reported labral tear length was greater for patients having surgery in the LD position (BC vs LD [mean ± SD], 123.5°± 49° vs 132.3°± 44°; P = .012). The LD position was associated with more anchors placed in the inferior glenoid and more frequent placement of anchors at the 6-o'clock (BC vs LD, 22.4% vs 51.6%; P < .001). The LD position was more frequently associated with utilization of ≥4 total anchors (BC vs LD, 33.5% vs 46.1%; P < .001). CONCLUSION Surgeons utilizing the LD position for arthroscopic capsulolabral repair in patients with anterior shoulder instability more frequently placed anchors in the inferior glenoid and at the 6-o'clock position. Additionally, surgeon-reported labral tear length was longer when utilizing the LD position. These results suggest that patient positioning may influence the total number of anchors used, the number of anchors used in the inferior glenoid, and the frequency of anchor placement at the 6 o'clock position during arthroscopic capsulolabral repair for anterior shoulder instability. How these findings affect clinical outcomes warrants further study. REGISTRATION NCT02075775 (ClinicalTrials.gov identifier).

Abstract
AIMS The purpose of this study was to assess total knee arthroplasty (TKA) volume and rates of early complications in morbidly obese patients over the last decade, where the introduction of quality models influencing perioperative care pathways occurred. METHODS Patients undergoing TKA between 2011 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Patients were stratified by BMI < 40 kg/m2 and ≥ 40 kg/m2 and evaluated by the number of cases per year. The 30-day rates of any complication, wound complications, readmissions, and reoperation were assessed. Trends in these endpoints over the study period were compared between groups using odds ratios (ORs) and multivariate analyses. RESULTS In total, 314,695 patients underwent TKA and 46,362 (15%) had BMI ≥ 40 kg/m2. The prevalence of morbid obesity among TKA patients did not change greatly, ranging between 14% and 16%. Reoperation rate decreased from 1.16% to 0.96% (odds ratio (OR) 0.81 (95% confidence interval (CI) 0.66 to 0.99)) for patients with BMI < 40 kg/m2, as did rates of readmission (4.46% to 2.87%; OR 0.61 (0.55 to 0.69)). Patients with BMI ≥ 40 kg/m2 also had fewer readmissions over the study period (4.87% to 3.34%; OR 0.64 (0.49 to 0.83)); however, the rate of reoperation did not change (1.37% to 1.41%; OR 0.99 (0.62 to 1.56)). Significant improvements were not observed for infective complications over time for either group; patients with BMI ≥ 40 kg/m2 had increased risk of both deep infection and wound complications compared to non-morbidly obese patients. Rate of any complication decreased for all patients. CONCLUSION The proportion of TKAs in morbidly obese patients has not significantly changed over the past decade. Although readmission rates improved for all patients, reductions in reoperation in non-morbidly obese patients were not experienced by the morbidly obese, resulting in a widening of the complication gap between these cohorts. Care improvements have not lowered the differential risk of infective complications in the morbidly obese. Cite this article: Bone Joint J 2021;103-B(6 Supple A):38-44.

Abstract
BACKGROUND Active dental infection at the time of total joint arthroplasty (TJA) or in the acute postoperative period following TJA is thought to increase the risk of periprosthetic joint infection (PJI). Many surgeons recommend preoperative dental screening. This study aimed to identify how many elective TJA patients failed preoperative dental screening and what patient risk factors were associated with failure. METHODS A consecutive series of elective, primary TJA was reviewed from 8/1/2016 to 8/1/2017. We studied 511 operations in 511 patients. All patients were referred for preoperative dental screening per protocol. Dental screening failure was defined as required dental intervention by the dentist. Screening failure rate was calculated for and logistic regression was used to evaluate the relationship between odds of screening failure and patient demographic data. RESULTS In 94 of the 511 total cases (18.5%), patients failed dental screening and required dental procedures prior to TJA. Reasons for failure included tooth extractions, root canals, abscess drainage, and carious lesions requiring filling. Patient characteristics associated with failed dental screening included male gender (odds ratio 1.56, 95% confidence interval 1.0006-2.468, P = .047) and current smoker (odds ratio 3.6, 95% confidence interval 1.650-7.927, P = .001). CONCLUSION Universal dental screening prior to primary TJA resulted in 18.5% of patients needing an invasive dental intervention. Universal dental screening results in extra cost and time for patients and providers. Although male gender and active smoking were associated with increased odds of requiring an invasive dental procedure, more work is needed to develop targeted screening to improve perioperative workflow and limit unnecessary dental evaluations for patients.

Abstract
BACKGROUND There have been significant advancements in perioperative total hip arthroplasty (THA) care and it is essential to quantify efforts made to better optimize patients and improve outcomes. The purpose of this study is to assess trends in discharge destination, length of stay (LOS), reoperations, and readmissions following THA. METHODS Patients undergoing primary THA were identified using International Statistical Classification of Diseases and Current Procedural Terminology codes in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and Humana claims databases. Discharge destinations were assessed and categorized as home or not home. Trends in discharge destination, LOS, readmissions, reoperation, and comorbidity burden were assessed. RESULTS In ACS NSQIP, 155,637 patients underwent THA and the percentage of patients discharging home increased from 72.2% in 2011 to 87.0% in 2017 (P < .0001). In Humana, 84,832 THA patients were identified, with an increase in home discharge from 56.6% to 72.8% (P < .0001). LOS decreased and proportion of patients with an American Society of Anesthesiologists score ≥3 or Charlson Comorbidity Index ≥2 increased significantly for both home and nonhome going patients. Patients discharged home had a decrease in readmissions in both databases. CONCLUSION Patients undergoing THA more often discharged home and had shorter hospital LOS with lower readmission rates, despite an increasingly comorbid patient population. It is likely these changes in disposition and LOS have resulted in significant cost savings for both payers and hospitals. The efforts necessary to maintain improvements should be considered when changes to reimbursement are being evaluated. ACS NSQIP hospitals had a larger proportion of patients discharged home and the source of data used to benchmark hospitals should be considered as findings may differ.

Abstract
Total ankle arthroplasty (TAA) use has increased during the past 20 years, whereas ankle arthrodesis (AAD) use has remained constant. The purpose of this study was to examine trends in TAA and AAD use in American Board of Orthopedic Surgery Part II candidates while considering the influence of fellowship training status on treatment of end-stage ankle arthritis. The American Board of Orthopedic Surgery Part II database was queried to identify all candidates who performed ≥1 TAA or AAD from examination years 2009 through 2018. Candidates were categorized by examination year and by self-reported fellowship training status. Descriptive statistical methods were used to report procedure volumes. Trends in use of TAA and AAD were examined by using log-modified regression analyses. From 2009through 2018, there was no significant change in TAA or AAD use among all candidates (p = .92, p = .20). Candidates reporting a foot and ankle fellowship trended toward increased use of TAA relative to AAD compared with non-foot and ankle fellowship candidates, but this failed to reach statistical significance (p = .06). The use of arthroscopic AAD increased over time (p < .01) among all candidates. TAA and AAD use did not change over the study period. Volume of TAA and AAD performed by early-career surgeons remains low. The findings in this study should serve as an important reference for orthopedic trainees, early-career surgeons, and orthopedic educators interested in optimizing training curriculum for surgical management of end-stage ankle arthritis.

Abstract
BACKGROUND During the novel Coronavirus 2019 (COVID-19) worldwide pandemic, viral testing has largely focused on patients presenting with fever and respiratory symptoms. Although Centers for Disease Control has reported 1,551,095 cases in the United States as of May 21, 2020, asymptomatic infection rates remain unknown within the U.S., especially in geographically disparate regions. METHODS On April 7, 2020 our hospital established universal SARS-CoV-2 screening using RT-PCR RNA detection from nasopharyngeal swabs from asymptomatic patients prior to essential and elective surgeries. This study included 1,997 asymptomatic patients undergoing surgical procedures and 1,797 admitted for medical management at a Midwestern academic hospital between April 7, 2020 and May 21, 2020. RESULTS As of May 21, asymptomatic testing for SARS-CoV-2 infection had been completed for 1,997 surgical patients and 1,797 non-surgical patients. Initial testing was positive in 26 patients, with an additional four positive tests occurring during repeat testing when greater than 48 hours had elapsed since initial testing. Overall asymptomatic infection rate was 0.79%. Asymptomatic infection rate was significantly lower in surgical patients (0.35% vs. 1.28%, p=0.001). Surgical patients tended to be older than non-surgical patients, although this was not statistically significant (51, IQR 27-65 vsx 46, IQR 28-64, p=0.057). Orthopedic surgery patients were significantly younger than those from other surgical services (42 vs. 53 yrs, p<0.001), however orthopedic and non-orthopedic surgical patients had similar asymptomatic infection rates (0.70% vs. 0.25%, p=0.173). CONCLUSION Among asymptomatic patients tested at a Midwestern academic medical center, 0.79% were infected with SARS-CoV-2 virus. These findings will help guide screening protocols at medical centers while providing essential and elective procedures during the COVID-19 pandemic. While the asymptomatic infection rate was low, this data substantiates the threat of asymptomatic infections and potential for community viral spread. These results may not be generalizable to large urban population centers or areas with high concentrations of COVID-19, each region must use available data to evaluate the risk-benefit ratio of universal testing vs universal contact precautions.Level of Evidence: IV.

Abstract
BACKGROUND Intraoperative neurological monitoring (IONM) is commonly used in spine surgery. However, the utility of IONM in anterior cervical decompression and fusion (ACDF) remains a topic of debate. The purpose of the study was to investigate the utility and cost of IONM (both Somatosensory evoked potentials (SSEPs) and Motor Evoked Potentials (Tc-MEPs)) in reducing postoperative neurological deficits in myelopathic and non-myelopathic patients undergoing ACDF. METHODS Retrospective chart review was performed to include only patients with cervical radiculopathy or myelopathy undergoing one or two level ACDF over a 7-year period at a busy academic center. SSEP and Tc-MEP tracings were reviewed for all monitored patients and significant changes and inconsistencies were noted. IONM billing codes (SSEP/Tc-MEP) were reviewed and summed to evaluate the average procedural cost. Medical records were reviewed for preoperative physical exam and for new postoperative neurological deficits on postoperative day one and again at six weeks and matched to the monitored tracings. RESULTS There were 249 total patients (48 Non-monitored, 201 monitored). There was no difference in gender, age, or BMI between monitored and non-monitored groups. There was no difference in new neurological deficits in monitored compared with non-monitored patients with radiculopathy (p=0.1935) or myelopathy (p=0.1977). However, when radiculopathy and myelopathy patients were combined, there was an increased incidence of new neurologic deficits in monitored patients (8.0%) versus non-monitored patients (0%) (p=0.0830). All new neurological deficits occurred in patients with normal IONM tracings. There were no new neurologic deficits in the non-monitored radiculopathy or myelopathy groups. The average IONM procedure charge was $6500. CONCLUSION Our results indicate that intraoperative spinal cord monitoring did not reduce new neurological deficits in our cohort of patients. The higher incidence in new neurological deficits despite no IONM changes in our monitored group suggests a lack of utility of IONM in ACDF. Furthermore, at an average of $6500 per IONM procedure, the present study underlines the importance of prudence when choosing to use IONM in the era of cost containment.Level of Evidence: III.

Abstract
Background Arthroscopic subtalar arthrodesis was first described over 2 decades ago and originally performed in the lateral decubitus or supine position using anterolateral and posterolateral portals situated about the fibula. More recently, several authors have advocated for prone positioning utilizing posteromedial and posterolateral portals with an optional accessory lateral portal. To date, a comparison of these techniques has been limited. Purpose To determine the effect of patient positioning and portal placement on complication rates after arthroscopic subtalar arthrodesis. Study Design Systematic review; Level of evidence, 4. Methods A systematic review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Patients were placed into 1 of 3 groups: the lateral group if they were positioned lateral or supine with lateral-based portals; the 2-portal prone group if they were positioned prone with posteromedial and posterolateral portals; or the 3-portal prone group if posteromedial, posterolateral, and accessory lateral portals were utilized in the prone position. Inverse variance-weighted fixed-effects models were used to evaluate pooled estimates. Results A total of 20 studies examining 484 feet in 468 patients with a mean follow-up of 36.1 months were included for analysis. Overall, 8 studies examined patients in the prone position with 2 posterior portals (n = 111; 22.9%), 7 articles evaluated lateral portals (n = 182; 37.6%), and 5 studies examined patients in the prone position with 3 portals (n = 191; 39.5%). The total complication rate was similar (P = .620) between the 2-portal prone (18.9%), 3-portal prone (17.8%), and lateral (17.6%) groups. There was no difference observed in the rate of complications secondary to portal placement (P ≥ .334), rate of painful hardware (P ≥ .497), and rate of repeat surgery (P ≥ .304). The 2-portal prone group had a significantly higher rate of nonunion than the lateral group (8.1% vs 1.1%, respectively; P = .020) but not the 3-portal prone group (5.8%; P = .198). Conclusion The current study demonstrated a higher rate of nonunion following arthroscopic subtalar arthrodesis with prone patient positioning using posteromedial and posterolateral portals without an accessory lateral portal.

Abstract
Background: The Patient-Reported Outcome Measurement Information System (PROMIS) was developed to improve patient-reported outcome measures (PROMs) and administration through a computer adaptive test (CAT). The PROMIS physical function-CAT (PF-CAT) has not been investigated in patients with patellofemoral instability (PFI). Purpose/Hypothesis: The purpose of this study was to evaluate the construct validity of the PROMIS PF-CAT with previously validated tools for measuring PROMs in patients with a diagnosis of PFI. We hypothesized that the PF-CAT will have the strongest correlations with other PROMs that evaluated PF as well as moderate correlations with PROMs that measured other health domains. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Patients enrolled in this study who underwent operative intervention for PFI completed the following evaluations preoperatively: PROMIS PF-CAT, 36-Item Short Form Health Survey (SF-36), Knee injury and Osteoarthritis Outcome Score (KOOS), EuroQol-5 dimensions (EQ-5D), and Kujala Anterior Knee Pain Scale (AKPS). Correlation coefficients and the percentage of patients achieving the highest and lowest possible outcome score of each instrument were calculated to assess floor and ceiling effects. Statistical significance was defined as P < .05. Results: In total, 91 participants (63.7% females; mean age, 20.1 ± 7.2 years) completed the questionnaires. PF-CAT had the lowest number of questions (4.3 ± 1.1). The strongest correlations were between the PF-CAT and SF-36 PF subscale (r = 0.78; P < .01), AKPS (r = 0.68; P < .01), and KOOS Activities of Daily Living subscale (r = 0.68; P < .01). Correlation was moderate between the PF-CAT and the KOOS subscales of Sports/Recreation (r = 0.58; P < .01), Quality of Life (r = 0.53; P < .01), and Symptoms (r = 0.47; P < .01). The PROMIS PF-CAT demonstrated no floor or ceiling effects. Conclusion: In patients with PFI, construct validity of the PROMIS PF-CAT was supported by strong correlations demonstrated between the PF-CAT and PROMs evaluating PF and moderate correlations with those assessing other health domains. Our results demonstrated a low respondent burden and no floor or ceiling effects associated with the PROMIS PF-CAT. The PROMIS PF-CAT may be considered a beneficial alternative to previously established PF PROMs for preoperative evaluation of patients with PFI.

Abstract
BACKGROUND Although a sex-based balance in US graduate medical education has been well-documented, a discrepancy remains in orthopaedic surgery. In orthopaedic sports medicine, the representation of women as team physicians has not previously been characterized. PURPOSE To quantify the sex-related composition of team physicians of select National Collegiate Athletic Association (NCAA) Division I collegiate and professional teams. Additionally, the authors assess the sex-related composition of orthopaedic surgeon team physicians specifically and compare these proportions to the sex-related composition of orthopaedic surgeon membership of the American Orthopaedic Society for Sports Medicine (AOSSM). STUDY DESIGN Cross-sectional study. METHODS Publicly available sex-related data were collected for team physicians in select NCAA Division I collegiate conferences and professional sports organizations. Subspecialty characteristics and sex distribution were described by use of percentages. Chi-square tests were used to assess whether sex distributions of team physicians in collegiate and professional sports were (1) representative between the populations of female and male physicians compared with the general public and (2) representative of the sex-based composition of orthopaedic surgeons nationally. RESULTS Women represented 12.7% (112/879) of all team physicians and 6.8% (30/443) of all orthopaedic surgeons (P < .0001). More than half (53.9%; 413/767) of male and 26.8% (30/112) of female team physicians were orthopaedic surgeons. In collegiate athletics, women comprised 18.1% of all team physicians and 7.7% of orthopaedic surgeon team physicians. In professional sports, women comprised 6.7% of all team physicians and 6.3% of orthopaedic surgeon team physicians, with the greatest proportion in the Women's National Basketball Association (31.3%). CONCLUSION Women comprise a minority of team physicians in select NCAA Division I collegiate and professional sports organizations. When compared with the composition of AOSSM orthopaedic surgeon membership, expected female orthopaedic surgeon representation varies between conferences and leagues with little statistical significance. Although efforts have been made to increase sex-based diversity in orthopaedic surgery, results of this study suggest that barriers affecting female orthopaedic surgeons as team physicians should be identified and addressed.

Abstract
Background In the setting of anterior shoulder instability, it is important to assess the reliability of orthopaedic surgeons to diagnose pathologic characteristics on the 2 most common imaging modalities used in clinical practice: standard plain radiographs and magnetic resonance imaging (MRI). Purpose To assess the intra- and interrater reliability of diagnosing pathologic characteristics associated with anterior shoulder instability using standard plain radiographs and MRI. Study Design Cohort study (diagnosis); Level of evidence, 3. Methods Patient charts at a single academic institution were reviewed for anterior shoulder instability injuries. The study included 40 sets of images (20 radiograph sets, 20 MRI series). The images, along with standardized evaluation forms, were distributed to 22 shoulder/sports medicine fellowship-trained orthopaedic surgeons over 2 points in time. Kappa values for inter- and intrarater reliability were calculated. Results The overall response rate was 91%. For shoulder radiographs, interrater agreement was fair to moderate for the presence of glenoid lesions (κ = 0.49), estimate of glenoid lesion surface area (κ = 0.59), presence of a Hill-Sachs lesion (κ = 0.35), and estimate of Hill-Sachs surface area (κ = 0.50). Intrarater agreement was moderate for radiographs (κ = 0.48-0.57). For shoulder MRI, interrater agreement was fair to moderate for the presence of glenoid lesions (κ = 0.44), glenoid lesion surface area (κ = 0.35), Hill-Sachs lesion (κ = 0.33), Hill-Sachs surface area (κ = 0.28), humeral head edema (κ = 0.41), and presence of a capsulolabral injury (κ = 0.36). Fair agreement was found for specific type of capsulolabral injury (κ = 0.21). Intrarater agreement for shoulder MRI was moderate for the presence of glenoid lesion (κ = 0.59), presence of a Hill-Sachs lesion (κ = 0.52), estimate of Hill-Sachs surface area (κ = 0.50), humeral head edema (κ = 0.51), and presence of a capsulolabral injury (κ = 0.53), and agreement was substantial for glenoid lesion surface area (κ = 0.63). Intrarater agreement was fair for determining the specific type of capsulolabral injury (κ = 0.38). Conclusion Fair to moderate agreement by surgeons was found when evaluating imaging studies for anterior shoulder instability. Agreement was similar for identifying pathologic characteristics on radiographs and MRI. There was a trend toward better agreement for the presence of glenoid-sided injury. The lowest agreement was observed for specific capsulolabral injuries.

Abstract
BACKGROUND Rotator cuff (RTC) repair is performed using open/mini-open or arthroscopic procedures, and the use of arthroscopic techniques is increasing. The extent to which surgery has transitioned from open to arthroscopic techniques has yet to be elucidated. QUESTIONS/PURPOSES The purpose of this study was to evaluate trends in open and arthroscopic rotator cuff repair in the USA and describe tendencies in treatment across gender, age, and geographic region. We hypothesized that surgeons would be more likely to perform arthroscopic rotator cuff repair, with similar trends across the USA. METHODS A retrospective review of a comprehensive national insurance database (Humana) was performed using the PearlDiver software for all patients who underwent RTC repair between January 2007 and June 2015. Patients were identified by Current Procedural Terminology (CPT) codes. χ 2 tests evaluated the proportion of arthroscopic surgeries by gender and geographic region; logistic regression analysis assessed differences from 2007 to 2015. RESULTS In the study period, 54,740 patients underwent RTC repair (68% arthroscopic, 52% male), with the highest frequency of RTC repair in patients between 65 and 69 years old. The proportion of open RTC repair increased with increasing patient age, with no significant difference between men and women. The proportion of arthroscopic RTC surgeries increased from 56.9% in 2007 to 75.1% in 2015. The overall trend was 188% increase in total RTC repairs. Arthroscopic repair was more frequent than open repair in all US regions, with the highest proportion in the South. CONCLUSION Arthroscopic RTC surgery predominates and continues to rise. With increasing patient age, there was an increase in the proportion of open repair. The majority of RTC repairs were performed in patients between 65 and 69 years of age.

Abstract
Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) was
developed to capture patient-reported outcomes (PROs) in an efficient
manner. Few studies have assessed this instrument postoperatively. Purpose: To compare the PROMIS Physical Function computer adaptive test (PROMIS PF
CAT) and Upper Extremity (PROMIS UE) item bank to other previously validated
PRO instruments and to evaluate ceiling and floor effects and construct
validity responsiveness in patients who underwent operative interventions
for shoulder instability. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 72 patients who underwent operative interventions for shoulder
instability completed the American Shoulder and Elbow Surgeons (ASES)
assessment form, Marx shoulder activity scale (Marx), 36-Item Short Form
Health Survey physical function (SF-36 PF) and general health (SF-36 GH),
Western Ontario Shoulder Instability Index (WOSI), PROMIS PF CAT, and PROMIS
UE before surgery and then at 6 weeks and 6 months postoperatively.
Correlation coefficients were calculated among these tools. The effect size
of change was also calculated for each tool at each time point. A total of
91 patients who had also undergone surgery for shoulder instability
completed these PRO instruments 2 years postoperatively. The percentage of
patients hitting the ceiling and floor effects of each of the PRO
instruments was calculated at all time points. Results: The PROMIS PF CAT demonstrated excellent-good correlation with the SF-36 PF
at all postoperative time points (0.61 at 6 weeks, 0.68 at 6 months, and
0.64 at 2 years; P < .01 for all). The PROMIS UE showed
excellent correlation with the ASES at 6 weeks postoperatively (0.73,
P < .01). Both the PROMIS PF CAT and PROMIS UE
demonstrated the ability to detect change after surgical interventions with
a medium to large effect size. The PROMIS UE demonstrated a ceiling effect
at 6 months (68.1%) and 2 years (67.0%) postoperatively. The PROMIS PF CAT
demonstrated no ceiling effect at any time point. Conclusion: The PROMIS PF CAT demonstrated good to excellent correlation with other
previously validated PRO instruments that assess physical function in
patients with shoulder instability postoperatively. The PROMIS UE
demonstrated good correlation with other PRO tools but had a significant
ceiling effect and is not recommended for this patient population. Both
tools demonstrated an ability to detect change after surgical interventions
with a good effect size.

Abstract
PURPOSE The purpose of this study is to evaluate the trends in labral repair in American Board of Orthopaedic Surgery Part II candidates performing hip arthroscopy. METHODS Candidates who performed arthroscopic hip surgery between 2011 and 2015 during their American Board of Orthopaedic Surgery Part II board collection period were identified using Current Procedural Terminology codes (29860, 29861, 29862, 29863, 29914, 29915, 29916). The proportion of hip arthroscopy cases including labral repair (Current Procedural Terminology code 29916) were calculated for each year and analyzed by fellowship training experience. Trends in labral repair utilization were calculated using univariate and regression analyses, with significance set at P < .05. RESULTS During the study period, 1,606 hip labral repair cases were performed, with a 35% increase in utilization between 2011 and 2015. Overall, labral repair was performed in 64.8% (1,606/2,480) of hip arthroscopy cases, with a significant increase between 2011 and 2015 (47.4% vs 79.2%; P < .001). Of the hip arthroscopy cases including labral repair, 80.4% (1,291/1,606) were performed by candidates with sports medicine fellowship training. The proportion of hip arthroscopy cases including labral repair was highest for surgeons with sports medicine fellowship training compared with those without sports medicine fellowship training (66.1% vs 59.8%; P = .007). Candidates with sports medicine training performing at least 1 labral repair each year increased from 68% to 89% over the study period (P = .0007). The average number of labral repairs per candidate increased significantly over the duration of the study period (P = .0072). CONCLUSIONS Labral repair utilization during hip arthroscopy procedures nearly doubled from 2011 to 2015 for American Board of Orthopaedic Surgery Part II candidates, reflecting a significant change in practice. Current data suggest that nearly 80% of hip arthroscopy procedures include labral repair. These trends may reflect the current practice patterns at academic institutions with sports medicine fellowships.

Abstract
PURPOSE To determine pre- and postoperative opioid utilization while identifying risk factors for prolonged postoperative opioid use following hip arthroscopy. METHODS All patients undergoing hip arthroscopy between 2007 and the second quarter of 2016 were identified within the Humana Inc. administrative claims database. Chronic preoperative opioid utilization was defined as filling of any opioid prescription 1 to 3 months before surgery, whereas acute preoperative opioid utilization was defined as filling any opioid prescription within 1 month of surgery. Rates of pre- and postoperative opioid utilization were calculated, and patient demographic characteristics and medical conditions associated with pre- and postoperative opioid utilization were identified. RESULTS Of the 1,208 patients undergoing hip arthroscopy, chronic and acute preoperative opioid utilization was observed in 24.9% and 17.3% of patients, respectively. Chronic preoperative opioid utilization was more frequently observed in obese (P < .001) patients, those ≥50 years of age (P = .002), and those with preexisting anxiety and/or depression (P < .001). In multivariate analysis, chronic preoperative opioid utilization was the strongest predictor of opioid prescription filling at 3, 6, 9, and 12 months postoperatively (odds ratio at 3 months, 18.60, 95% confidence interval, 12.41 to 28.55), whereas preexisting anxiety and/or depression and obesity were additionally identified as predictors of prolonged postoperative opioid utilization. CONCLUSIONS Chronic preoperative opioid utilization before hip arthroscopy is common at 24.9%. The high rate of chronic preoperative opioid utilization is particularly important considering that chronic preoperative opioid utilization is the strongest predictor of continued postoperative opioid prescription filling out to 12 months postoperatively. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND The purpose of this study was to perform a systematic review and meta-analysis to quantitatively assess the association between tobacco use and the risk of any wound complication and periprosthetic joint infection (PJI) after primary total hip and total knee arthroplasty procedures. METHODS Relevant articles published before January 2018 were identified by systematically searching PubMed, EMBASE, and Cochrane library databases. Pooled odds ratios (OR) and 95% confidence intervals were calculated for end points of any wound complication and PJI. Additional analyses were performed to evaluate risks between current, former, and non-tobacco users. RESULTS Fourteen studies were included in the meta-analysis. Tobacco users had a significantly higher risk of wound complications (OR, 1.78 [1.32-2.39]) and PJI (OR, 2.02 [1.47-2.77]) compared to non-tobacco users. Compared to non-tobacco users, there was an increased risk of PJI among current (OR, 2.16 [1.57-2.97] and former (OR, 1.52 [1.16-1.99]) tobacco users. Current tobacco users also had a significantly increased risk of PJI compared to former tobacco users (OR, 1.52 [1.07-2.14]). CONCLUSION Tobacco use before total hip and total knee arthroplasty significantly increases the risk of wound complications and PJI. This increased risk is present for both current and former tobacco users. However, former tobacco users had a significantly lower risk of wound complications and PJI compared to current tobacco users, suggesting that cessation of tobacco use before TJA can help to mitigate these observed risks.

Abstract
BACKGROUND Metacarpal and phalanx fractures are common among professional athletes. There is a paucity of data to guide team physicians on expected return to play after hand fractures. The purpose of this study was to examine the epidemiology and return to play times after hand fractures in NCAA athletes. We hypothesized that surgical management of fractures may expedite return to play times. METHODS The NCAA Injury Surveillance Program database was queried for metacarpal and phalanx fractures during the 2009-2014 seasons in all sports. Injury rates per 100,000 athleteexposures (AEs) were calculated. Student's t-test, Wilcoxon Rank sum tests, Chi-Squared tests, and Fisher Exact Test were used. Statistical significance was set to p<0.05. RESULTS Sports with the highest rates of phalanx and metacarpal fractures included Men's Football, Men's Ice Hockey, Men's Wrestling, and Women's Field Hockey. Multiple sports had participants with no hand fractures over the study period. Male student-athletes with metacarpal fractures treated operatively returned to play at a mean of 31.8±29.4 days versus 13.8±23.6 days for those treated non-operatively. 92% of male student-athletes were able to return to sport in the same season without operative management versus 67% with operative management. Female student-athletes had a cohort too small for statistical analysis. Return to play times for male student-athletes with phalanx fractures were not significantly different between operative and non-operative groups (16.1±21.5 days versus 7.1±13.3 days). CONCLUSIONS Hand fractures are relatively common among NCAA student-athletes participating in contact sports. Student-athletes with metacarpal fractures returned to play at an average of 2-4 weeks after injury; those with phalanx fractures returned at an average of 1-2 weeks. The return to play times illustrated within this study can be used to counsel athletes, athletic trainers, and coaches.Level of evidence: IV.

Abstract
BACKGROUND Overlapping surgery is common in high-volume total knee arthroplasty (TKA) practices and has come under recent scrutiny in the press. The aim of this study was to evaluate differences in 6-week clinical and radiographic outcomes for primary TKA patients between single and overlapping operating room (OR) days. METHODS We retrospectively reviewed individual patient records of a consecutive series of primary TKAs with complete 6-week follow-up performed by a single academic surgeon between 2008-2016 (N= 452). Patients were stratified by single vs. overlapping OR days. 177 patients (39%) had an overlapping surgery. Age, body mass index (BMI), Charlson Comorbidity Index (CCI) and American Society of Anesthesiologists (ASA) class were recorded to assess for confounding variables. Outcomes included anesthesia time, 6-week readmission, unplanned return to OR, medical and surgical complication, and 6-week radiographic alignment. RESULTS There were no significant differences in anesthesiology time (165.5 vs 164.5 min, p=0.85), medical or surgical complication rates (10.5% vs 6.2%, p=0.11), 6-week readmissions (4.4% vs 1.7%, p=0.12), or return to OR (1.8% vs 1.7%, p=1.00) before or after adjusting for age, BMI, gender, ASA and CCI. There was no difference between overlapping and single OR cohorts in rate of neutral coronal alignment (2°-8° valgus) (98.3% vs 98.9%, respectively, p=0.68) or presence of periprosthetic lucency (p=0.43). CONCLUSIONS This study demonstrates no differences in 6-week clinical or radiographic outcomes between patients undergoing primary TKA on single versus overlapping OR days. These results support the safe practice of overlapping surgical scheduling in high-volume primary TKA centers.Level of Evidence: III.

Abstract
Contralateral knee pain has been suggested to be associated with muscle weakness in a pain-free knee, potentially through a mechanism of central nervous inhibition. Whether contralateral knee pain also affects muscle strength in a painful knee, however, is unknown. Here we study the extent to which isometric muscle strength differs between matched painful limbs of people with unilateral knee pain vs. matched painful limbs people with bilateral knee pain. To that end, 163 participants with unilateral knee pain were identified from the Osteoarthritis Initiative. Unilaterally painful (UP) limbs were defined as having numerical rating scale (NRS) ≥4/10, infrequent/frequent pain in the painful limb, while contralateral pain-free limbs were defined by NRS=0-1, no/infrequent pain and Western Ontario and McMaster Universities Arthritis Index (WOMAC) ≤1. The comparator group were matched bilaterally painful (BP) limbs. Maximum isometric muscle strength (N) was compared between 1:1 matched BP and UP limbs. Extensor strength was found to be lower in BP limbs than in UP limbs, (-2.9%; p=0.39) but this difference was not statistically significant. Extensor strength was significantly lower in the UP vs. contralateral pain-free limbs (-6.2%; p<0.001). No differences were observed between BP and contralateral painful limbs (0.6%; p=0.87). In conclusion, the current results identify a slight reduction of maximum knee extensor strength in a painful limb, when the contralateral knee is also painful. In contrast to pain-free limbs, this effect did not reach statistical significance, but the overall findings support the concept of central nervous inhibition of muscle strength by contralateral knee pain.

Abstract
BACKGROUND Intra-articular glenohumeral joint changes frequently occur after shoulder instability events. PURPOSE (1) To compare demographic characteristics, baseline patient-reported outcomes, and intraoperative findings for patients undergoing primary or revision shoulder stabilization surgery and (2) to determine the incidence of glenohumeral bone and cartilage lesions in this population while identifying factors independently associated with these lesions. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS The Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Group shoulder instability database was used to identify all prospectively enrolled patients undergoing shoulder stabilization surgery for anterior instability between October 2012 and September 2016. Any patient who underwent surgery for posterior or multidirectional shoulder instability or concomitant rotator cuff repair surgery was excluded. Patient demographic characteristics, preoperative patient-reported outcomes, and intraoperative findings, including glenohumeral bone and cartilage lesions, were compared for patients undergoing primary and revision shoulder stabilization surgery. Additionally, patients with and without glenohumeral bone and cartilage lesions were compared and independent associations determined using multivariate analysis. RESULTS There were 545 patients available for analysis (461/545 [84.6%] primary; 84/545 [15.4%] revision). Patients undergoing revision surgery were older ( P = .001), were more frequently smokers ( P = .022), had a greater number of instability events before surgery ( P = .047), more frequently required reduction assistance ( P < .001), and had lower Short Form-36 (SF-36) Mental Component Summary ( P = .020) and Western Ontario Shoulder Instability Index (WOSI) ( P = .026) scores preoperatively. Additionally, patients undergoing revision surgery had a higher frequency of bone and cartilage lesions than those undergoing primary surgery (47.6% vs 18.4%, respectively; P < .001). Male sex, revision surgery, black race, increasing body mass index, increasing patient age, and lower preoperative SF-36 Physical Component Summary score were independently associated with the presence of glenohumeral bone and cartilage lesions at the time of shoulder stabilization surgery. Revision surgery was strongly associated with the presence of glenohumeral bone and cartilage lesions (odds ratio [OR], 4.381 [95% CI, 2.591-7.406]) and glenoid bone loss greater than 10% (OR, 9.643 [95% CI, 5.128-18.134]) or 20% (OR, 13.076 [95% CI, 5.113-33.438]) of the glenoid width. CONCLUSION Glenohumeral bone and cartilage lesions are common at the time of shoulder stabilization surgery, occurring more frequently in patients undergoing revision surgery as compared with primary surgery. On the basis of these findings, future prospective studies should aim to compare the clinical outcomes in these 2 groups.

Abstract
BACKGROUND The efficacy of corticosteroid and hyaluronic acid injections for knee osteoarthritis has been questioned. The purpose of this study was to determine the impact of the American Academy of Orthopaedic Surgeons (AAOS) clinical practice guidelines on the use of these injections in the United States and determine if utilization differed by provider specialty. METHODS Patients with knee osteoarthritis were identified within the Humana database from 2007 to 2015, and the percentage of patients receiving a knee injection relative to the number of patients having an encounter for knee osteoarthritis was calculated and was trended for the study period. The impact of each edition of the AAOS clinical practice guidelines on injection use was evaluated with segmented regression analysis. Injection trends were also analyzed relative to the specialty of the provider performing the injection. RESULTS Of 1,065,175 patients with knee osteoarthritis, 405,101 (38.0%) received a corticosteroid injection and 137,005 (12.9%) received a hyaluronic acid injection. The rate of increase in hyaluronic acid use, per 100 patients with knee osteoarthritis, decreased from 0.15 to 0.07 injection per quarter year (p = 0.02) after the first clinical practice guideline, and the increase changed to a decrease at a rate of -0.12 injection per quarter (p < 0.001) after the second clinical practice guideline. After the first clinical practice guideline, the rate of increase in utilization of corticosteroids, per 100 patients with knee osteoarthritis, significantly lessened to 0.12 injection per quarter (p < 0.001), and after the second clinical practice guideline, corticosteroid injection use plateaued (p = 0.72). The trend in use of hyaluronic acid injections by orthopaedic surgeons and pain specialists decreased with time following the second-edition clinical practice guideline but did not change for primary care physicians or nonoperative musculoskeletal providers. CONCLUSIONS Subtle but significant changes in hyaluronic acid and corticosteroid injections occurred following the publication of both clinical practice guidelines. Although the clinical practice guidelines did impact injection use, given the high costs of these injections and their questionable clinical efficacy, further interventions beyond publishing clinical practice guidelines are needed to encourage higher-value care for patients with knee osteoarthritis.
