RESUMEN
BACKGROUND: There is substantial corroborating evidence that orthopaedic surgery has historically been the least diverse of all medical and surgical specialties in terms of race, ethnicity, and sex. Growing recognition of this deficit and the benefits of a diverse healthcare workforce has motivated policy changes to improve diversity. To measure progress with these efforts, it is important to understand the existing representation of sexual and gender minorities among orthopaedic professionals. QUESTIONS/PURPOSES: (1) What proportion of American Academy of Orthopaedic Surgeons (AAOS) members reported their identity as a sexual or gender minority? (2) What demographic factors are associated with the self-reporting of one's sexual orientation and gender identity? METHODS: The AAOS published the updated membership questionnaire in January 2022 to collect information from new and existing society members regarding age and race or ethnicity and newly added categories of gender identity, sexual orientation, and pronouns. The questionnaire was updated with input from a committee of orthopaedic surgeons and researchers to ensure face validity. The AAOS provided a deidentified dataset that included the variables of interest: membership type, gender identity, sexual orientation, pronouns, age, race, and ethnicity. Of 35,427 active AAOS members, 47% (16,652) updated their membership questionnaire. To answer our first study question, we calculated the prevalence of participants who self-reported as lesbian, gay, bisexual, transgender, queer, or another sexual or gender minority identity (LGBTQ+) and other demographic characteristics of the 16,652 respondents. Categorical demographic data are described using frequencies and proportions. Median and IQR were used to describe the central tendency and variability. To answer our second study question, we conducted a stratified analysis to compare demographic characteristics between those who self-reported LGBTQ+ identity and those who did not. Visual methods (quantile-quantile plots) and statistical tests (Kolmogorov-Smirnov and Shapiro Wilk) confirmed that the age of AAOS member was not normally distributed. Therefore, a Kruskal Wallis test was used to determine the statistical associations between age and self-reported LGBTQ+ status. Chi-square tests were used to determine bivariate statistical associations between categorical demographic characteristics and self-reported LGBTQ+ status. A multivariable logistic regression model was developed to identify the independent demographic characteristics associated with respondents who self-reported LGBTQ+ identity. Further stratified analyses were not conducted to protect the anonymity of AAOS members. An alpha level of 5% was established a priori to define statistical significance. RESULTS: Overall, 3% (109 of 3679) and fewer than 1% (3 of 16,182) of the AAOS members (surgeons, clinicians, allied healthcare providers, and researchers) who updated their membership profiles reported identifying as a sexual (lesbian, gay, bisexual, queer) or gender minority (nonbinary or transgender), respectively. No individual self-identified as transgender. Five percent (33 of 603) of women and 3% (80 of 3042) of men self-identified as a sexual minority (such as lesbian, gay, bisexual, or queer). AAOS members who self-identified as LGBTQ+ were younger (OR 0.99 [95% confidence interval (CI) 0.98 to 0.99]; p < 0.001), less likely to self-identify as women (OR 0.86 [95% CI 0.767 to 0.954]; p < 0.001), less likely to be underrepresented in medicine (OR 0.49 [95% CI 0.405 to 0.599]; p < 0.001), and less likely to be an emeritus or honorary member (OR 0.75 [95% CI 0.641 to 0.883]; p < 0.003). CONCLUSION: The proportion of self-reported LGBTQ+ AAOS members is lower than the 7% of the general US population. The greater proportion of younger AAOS members reporting this information suggests progress in the pursuit of a more-diverse field. CLINICAL RELEVANCE: The study findings support standardized collection of sexual orientation and gender identity data to better identify and address diversity gaps. As orthopaedic surgery continues to transform to reflect the diversity of musculoskeletal patients, all orthopaedic professionals (surgeons, clinicians, allied healthcare providers, and researchers), regardless of their identities, are essential in the mission to provide equitable and informed orthopaedic care. Sexual and gender minority individuals may serve as important mentors to the next generations of orthopaedic professionals; individuals from nonminority groups should serve as important allies in achieving this goal.

BACKGROUND: There is increasing appreciation of the distinction between gender and sex as well as the importance of accurately reporting these constructs. Given recent attention regarding transgender and gender nonconforming (TGNC) and intersex identities, it is more necessary than ever to understand how to describe these identities in research. This study sought to investigate the use of gender- and sex-based terminology in arthroplasty research. METHODS: The 5 leading orthopaedic journals publishing arthroplasty research were reviewed to identify the first twenty primary clinical research articles on an arthroplasty topic published after January 1, 2022. Use of gender- or sex-based terminology, whether use was discriminate, and whether stratification or adjustment based on gender or sex was performed, were recorded. RESULTS: There were 98 of 100 articles that measured a construct of gender or sex. Of these, 15 articles used gender-based terminology, 45 used sex-based terminology, and 38 used a combination of gender- and sex-based terminology. Of the 38 articles using a combination of terminology, none did so discriminately. All articles presented gender and sex as binary variables, and 2 attempted to explicitly define how gender or sex were defined. Of the 98 articles, 31 used these variables for statistical adjustments, though only 6 reported stratified results. CONCLUSIONS: Arthroplasty articles infrequently describe how gender or sex was measured, and frequently use this terminology interchangeably. Additionally, these articles rarely offer more than 2 options for capturing variation in sex and gender. Future research should be more precise in the treatment of these variables to improve the quality of results and ensure findings are patient-centered and inclusive.
RESUMEN
PURPOSE: The purpose of this study was to compare the rates of wound complications and heterotopic ossification (HO) between patients who underwent acute total elbow arthroplasty (TEA) and those who underwent delayed TEA performed for the treatment of distal humerus fractures. Our hypothesis was that delayed surgery will have fewer wound complications but a higher rate of HO. METHODS: We retrospectively reviewed 104 patients who had undergone TEA performed at 1 of 3 institutions following a distal humerus fracture. The acute cohort, comprising 69 patients, underwent TEA within 2 weeks; the delayed cohort, comprising 35 patients, received treatment between 2 weeks and 6 months. The rates of wound complications, HO, clinically relevant HO (requiring excision or resulting in loss of functional range of motion), and reoperation were recorded. These patients were followed up for an average of 52 (interquartile range, 18.5-117) weeks. RESULTS: Wound complications occurred in 10 patients (14.5%) in the early group and 7 (20.0%) in the delayed group. The overall rate of HO was 56.7% (59 patients). The rate of clinically relevant HO was 26.0% (27 patients), which was similar between the groups. Reoperation occurred in 20 patients (19.2%), which was similar between the groups. In the early group, 3 reoperations were performed for wound complications and 4 for HO. No patients required reoperation for these indications in the delayed group. The mean flexion-extension and supination-pronation arcs were 20°-130° and 80°-80°, respectively, which were similar between the groups. Rheumatoid arthritis and younger age were associated with increased odds of wound complications and reoperation. CONCLUSIONS: The rates of reoperation, wound complications, and HO were overall higher than those previously reported; however, the study was underpowered to determine a difference between early and delayed treatment. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
RESUMEN
BACKGROUND: Increasingly, dual mobility (DM) articulations have been used in revision total hip arthroplasty (THA), which may prevent postoperative hip instability. The purpose of this study was to report on outcomes of DM implants used in revision THA from the American Joint Replacement Registry (AJRR). METHODS: Revision THA cases performed between 2012 and 2018 Medicare were eligible and categorized by 3 articulations: DM, ≤32 mm, and ≥36 mm femoral heads. The AJRR-sourced revision THA cases were linked to Centers for Medicare and Medicaid Services (CMS) claims data to supplement (re)revision cases not captured in the AJRR. Patient and hospital characteristics were described and modeled as covariates. Using multivariable Cox proportional hazard models, considering competing risk of mortalities, hazard ratios were estimated for all-cause re-revision and re-revision for instability. Of 20,728 revision THAs, 3,043 (14.7%) received a DM, 6,565 (31.7%) a ≤32 mm head, and 11,120 (53.6%) a ≥36 mm head. RESULTS: At 8-year follow-up, the cumulative all-cause re-revision rate for ≤32 mm heads was 21.9% (95%-confidence interval (CI) 20.2%-23.7%) and significantly (P < .0001) higher than DM (16.5%, 95%-CI 15.0%-18.2%) and ≥36 mm heads (15.2%, 95%-CI 14.2%-16.3%). At 8-year follow-up, ≥36 heads had significantly (P < .0001) lower hazard of re-revision for instability (3.3%, 95%-CI 2.9%-3.7%) while the DM (5.4%, 95%-CI 4.5%-6.5%) and ≤32 mm groups (8.6%, 95%-CI 7.7%-9.6%) had higher rates. CONCLUSION: The DM bearings are associated with lower rates of revision for instability compared to patients who had ≤32 mm heads and higher revision rates for ≥36 mm heads. These results may be biased due to unidentified covariates associated with implant selection.

BACKGROUND: Periprosthetic joint infection (PJI) continues to challenge surgeons and patients. The burden of fungal organisms may represent approximately 1% of all PJI. Additionally, fungal PJI is difficult to treat. Most available case series are small and report poor success rates. Fungi are opportunistic pathogens and patients who have fungal PJI are believed to be immunocompromised. Additionally, fungal biofilms are more complex than those formed by other pathogens and confer additional drug resistance. Due to these factors, treatment failure is common. METHODS: A retrospective review of our institutional registry was performed to identify patients treated for fungal PJI. There were 49 patients identified with 8 excluded for not having follow-up, which left 22 knees and 19 hips for analyses. Demographics, clinical characteristics, and surgical details were collected. The primary outcome was failure defined as reoperation for infection following the index surgery for fungal PJI within 1 year of the index surgery. RESULTS: Failure occurred in 10 of 19 knees and 11 of the 22 hips. A higher proportion of patients who have extremity grade C failed treatment, and every patient who failed was host grade 2 or 3. The average number of prior surgeries and time from resection to reimplantation were similar between groups. CONCLUSION: To our knowledge, this represents the largest cohort of fungal PJIs reported in the literature to date. This data supports other literature in that failure rates were high. More study is needed to further understand this entity and improve care for these patients.

BACKGROUND: Nutritionally compromized patients, with preoperative serum albumin (SAB) < 3.5g/dL, are at higher risk for periprosthetic joint infection (PJI) in total joint arthroplasty. The relationship between nutritional and PJI treatment success is unknown. The purpose of this study was to examine the relationship between preresection nutrition and success after first-stage resection in planned two-stage exchange for PJI. METHODS: A retrospective review was performed on 418 patients who had first-stage resection of a planned two-stage exchange for chronic hip or knee PJI between 2014 and 2018. A total of 157 patients (58 hips and 99 knees) were included who completed first stage, had available preop SAB and had a 2-year follow-up. Failure was defined as persistent infection or repeat surgery for infection after resection. Demographic and surgical data were abstracted and analyzed. RESULTS: Among knee patients with preop SAB >3.5 g/dL, the failure rate was 32% (15 of 47) versus a 48% (25 of 40) failure rate when SAB <3.5 g/dL (P = .10). Similarly, the failure rate among hip patients with preop SAB >3.5 g/dL versus 12.5% (3 of 24) versus 44% (15 of 34) for hip patients with SAB <3.5 g/dL (P = .01). Multivariable regression results indicated that patients with SAB< 3.5 g/dL (P = .0143) and Musculoskeletal Infection Society host type C (P = .0316) were at an increased risk of failure. CONCLUSION: Low preoperative SAB and Musculoskeletal Infection Societyhost type-C are independent risk factors for failure following first-stage resection in planned two-stage exchange for PJI. Efforts to nutritionally optimize PJI patients, when possible, may improve the outcome of two-stage exchange.

Gluteal tendinopathy is a common source of impairment in adults due to degenerative changes in the gluteus medius tendon. We identified patients with gluteal tendinopathy who underwent surgery with a minimum six-month follow up. Radiographs, magnetic resonance images, demographic data, Hip Outcome Score (HOS), Veterans Rand 12-item health survey (VR-12), and a patient survey were reviewed. The cohort consisted of seventeen complete tears and thirty-one partial tears of the gluteal medius tendon (n = 48). Of patients, 72.9% reported satisfaction with surgery and noted 95.5% improvement in symptoms. Patients with partial tears demonstrated 90.0% improvement, while patients with complete tears noted 85% (p = 0.983). The median percent improvement for satisfied patients was 95.00 (85-100) and was significantly different from non-satisfied patients (p < 0.0001). Surgical repair resulted in higher HOS, activities of daily living (ADL), and HOS Sports scores. The majority of patients were satisfied with surgical treatment at follow up, noting near complete resolution in preoperative symptoms. (Journal of Surgical Orthopaedic Advances 32(2):075-082, 2023).

PURPOSE: To determine the reoperation rate, risk factors for reoperation, and patient-reported outcomes after isolated or combined tibial tubercle transfer and medial patellofemoral ligament reconstruction, for patellofemoral instability surgery. METHODS: Patient's records who underwent medial patellofemoral ligament reconstruction and/or tibial tubercle transfer for patellar instability by 35 surgeons from 2002 to 2018 at a single academic institution were retrospectively reviewed using CPT codes. Four-hundred-and-eighty-six patients were identified. Radiographic measurements, demographic parameters, and subsequent revision procedures and their indications were identified. A modified anterior knee pain survey was conducted by mail and with follow-up phone survey. RESULTS: The overall rate of reoperation was 120/486 (24.7%). The most common cause for reoperation was removal of hardware 42/486 (8.6%). The rate of reoperation for isolated medial patellofemoral ligament reconstruction 43/226 (19%) was lower than that of isolated tibial tubercle transfer 45/133 (33.8%) or a combined procedure 32/127 (25.2%) (P = 0.007). Woman had a higher rate of reoperation (29.4%) compared to men (15.9%) (P = 0.002). Patients at risk for a revision stabilization procedure included those with severe trochlear morphology (C or D) (6.1%) and those with Caton-Deschamps index > 1.3 (7.3%). Patients who underwent reoperation of any kind had poorer patient-reported outcomes. CONCLUSION: The overall reoperation rate after patellofemoral instability surgery remains high, and any reoperation portends worse patient-reported outcomes. Re-operations for instability are more likely in patients with trochlear dysplasia and patella alta and may benefit from more aggressive initial treatment, such as medial patellofemoral ligament reconstruction and tibial tubercle transfer in combination. Using the results of this study, surgeons will be able to engage in meaningful discussion with patients to counsel patients on expectations postoperatively. LEVEL OF EVIDENCE: IV.

BACKGROUND: Opiate-based regimens have been used as a foundation of postoperative analgesia in orthopedic surgery for decades, and the vast majority of orthopedic patients in the United States receive postoperative opioid prescriptions. Both the safety and efficacy of opioid use in orthopedic patients have been questioned because of mounting evidence that postoperative opioid use can be detrimental to outcomes and patient satisfaction. The purpose of this study is to compare a new, opioid-free pain management pathway with a traditional opioid-containing, multimodal pathway in patients undergoing shoulder arthroplasty. METHODS: This is a single-center randomized clinical trial in which 67 patients who underwent shoulder arthroplasty were allocated into 2 treatment arms: either a completely opioid-free, multimodal perioperative pain management pathway (OF), or a traditional opioid-containing perioperative pain management pathway (OC). Pain was measured on a numeric rating scale from 0 to 10 at 6-, 12-, 24-hour, 2-week, and 6-week time points. Deviations from the OF pathway, morphine milligram equivalents, readmissions, and opioid-related side effects were analyzed. RESULTS: Pain levels were significantly lower in the OF group at 12 hours, 24 hours, and 2 weeks. At 12 hours, the median pain rating was 0 compared with a median pain rating of 3 in the OC group (P = .003). At 24 hours, the OF group reported a median pain rating of 1 and the OC group reported a median pain rating of 4 (P < .001). The median pain rating at the 2-week time point in the OF group was 2 compared with 4 in the OC group (P = .006). Median pain ratings were similar between the OF group and the OC group at the 6-week time point. The median pain rating in the OF group at 6 weeks was 1, compared with 1.5 in the OC group. Of the 35 patients in the OF pathway, 1 required a rescue opioid medication for left cervical radiculopathy that ultimately necessitated cervical spine fusion after recovery from right shoulder arthroplasty, and 1 was noted to have taken an opioid medication, diverted from a prior prescription, at the 2-week visit. The morphine milliequivalents received in the OF group was 20 compared with 4936.25 in the OC group. There were no readmissions in the OF pathway, and no differences between the groups with regard to constipation, falls, or delirium. CONCLUSION: A multimodal, opioid-free perioperative pain management pathway is safe and effective in patients undergoing total shoulder arthroplasty and offers superior pain relief to that of a traditional opioid-containing pain management pathway at 12 hours, 24 hours, and 2 weeks postoperatively.

BACKGROUND: Open wound management in prosthetic joint infection (PJI) patients has been used in problematic dehisced wounds hoping to stimulate granulation tissue and closure. However, infections that start as a monomicrobial PJI can become polymicrobial with resultant worse outcomes following open wound management. This study assessed the relationship between open wound management and the development of polymicrobial periprosthetic joint infections. METHODS: We reviewed patients referred with a synovial cutaneous fistula. Patients with an open wound measuring less than 2 cm and less than two weeks of open wound management were excluded. Variables included original organisms cultured, type and length of open wound management, and organisms cultured at the time of revision infection surgery. RESULTS: Of the 65 patients with a previous monomicrobial infection treated with open wound management, 22/65 (34%) progressed to a polymicrobial infection. Thirty (46%) wounds were packed open with gauze, 20 (31%) were managed with negative pressure wound therapy, and 15 (23%) had surface dressings only. Of the 22 patients who converted to a polymicrobial infection, only 10 (45%) were infection free at follow-up. In contrast, 30 of 43 patients (70%) whose infections remained monomicrobial were infection free at follow-up. CONCLUSION: Open wound management can lead to conversion from a monomicrobial to a polymicrobial PJI, a rate of 34% in this series. Open prosthetic wound management should be discontinued for a fear of converting a monomicrobial infection to a difficult to treat polymicrobial infection. Surgeons must be prudent in the use of open wound management. LEVEL OF EVIDENCE: Level IV, Retrospective Case Series.

BACKGROUND: With the overwhelming use of cementless femoral fixation for primary total hip arthroplasty in the United States, the associations of stem fixation on the risk of revision and mortality are poorly understood. We evaluated the relationship between femoral fixation and risk of revision and mortality in patients included in the American Joint Replacement Registry. METHODS: Elective, primary, unilateral total hip arthroplasties in the American Joint Replacement Registry, in patients over the age of 65 years were considered. In total, 9,612 patients with a cemented stem were exact matched 1:1 with patients who received a cementless stem based on age, gender, and the Charlson Comorbidity Index. Outcomes compared between the groups included need and reason for revision at 90 days and 1 year; in-hospital, 90-day, and 1-year mortality; and mortality after early revision. Covariates were used in linear regression analyses. RESULTS: Cemented fixation was associated with a 37% reduction in the risk of 90-day revision, and a reduction in the risk of revision for periprosthetic fracture of 87% at 90 days and 81% at 1 year. Cemented fixation was associated with increased 90-day and 1-year mortality (odds ratio [OR] 3.15, confidence interval [CI] 2.24-4.43 and OR 2.36, CI 1.86-3.01, respectively). Patients who underwent subsequent revision surgery within the first year exhibited the highest mortality risk (OR 3.23, CI 1.05-9.97). CONCLUSION: In this representative sample of the United States, 90-day revision for any reason and for periprosthetic fracture was significantly reduced in patients with a cemented stem. This benefit must be weighed against the association with increased mortality and with the high risk of mortality associated with early revision, which was more prevalent with cementless fixation.

BACKGROUND: Standard treatment for periprosthetic joint infection (PJI) involves 2-stage exchange with placement of an antibiotic-impregnated cement spacer (ACS). Conflicting evidence exists on the role of ACS in development of acute kidney injury (AKI) after first-stage surgery. In this randomized clinical trial, we aimed to compare the incidence of AKI between the first-stage of a planned 2-stage exchange vs 1-stage exchange. This study design isolates the effect of the ACS in otherwise identical treatment groups. METHODS: The primary outcome variable was AKI, defined as a creatinine ≥1.5 times baseline or an increase of ≥0.3 mg/dL. Risk factors for AKI were evaluated using bivariate statistical tests and multivariable logistic regression. RESULTS: Patients who underwent the first stage of a planned 2-stage exchange were significantly more likely to develop AKI compared with the 1-stage exchange group (15 [22.7%] vs 4 [6.6%], P = .011). On multivariable regression analysis, ACS placement (odds ratio 7.48, 95% confidence limit 1.77-31.56) and chronic kidney disease (odds ratio 3.84, 95% confidence limit 1.22-12.08) were independent risk factors for AKI. CONCLUSION: Our study provides evidence that high-dose antibiotic cement spacers for treatment of PJI are an independent risk factor for AKI. Therefore, efforts to minimize nephrotoxicity should be employed in revision for PJI when possible.

Opioids are frequently used for acute pain management of musculoskeletal injuries, which can lead to misuse and abuse. This study aimed to identify the opioid prescribing rate for ankle fractures treated nonoperatively in the ambulatory and emergency department setting across a single healthcare system and to identify patients considered at high risk for abuse, misuse, or diversion of prescription opioids that received an opioid. A retrospective cohort study was performed at a large healthcare system. The case list included nonoperatively treated emergency department, urgent care and outpatient clinic visits for ankle fracture and was merged with the Prescription Reporting With Immediate Medication Mapping (PRIMUM) database to identify encounters with prescription for opioids. Descriptive statistics characterize patient demographics, treatment location and prescriber type. Rates of prescribing among subgroups were calculated. There were 1,324 patient encounters identified, of which, 630 (47.6%) received a prescription opioid. The majority of patients were 18-64 years old (60.3%). Patients within this age range were more likely to receive an opioid prescription compared to other age groups (p < .0001). Patients treated in the emergency department were significantly more likely to receive an opioid medication (68.3%) compared to patients treated at urgent care (33.7%) or in the ambulatory setting (16.4%) (p < .0001). Utilizing the PRIMUM tool, 14.2% of prescriptions were provided to patients with at least one risk factor. Despite the recent emphasis on opioid stewardship, 14.2% of patients with risk factors for misuse, abuse, or diversion received opioid analgesics in this study, identifying an area of improvement for prescribers.

PURPOSE: To examine allograft augmentation of undersized hamstring (HS) autograft tendons at the time of anterior cruciate ligament (ACL) reconstruction, compared with un-augmented autograft HS ACL reconstruction. METHODS: Patients who underwent ACL reconstruction at our institution between 2005 and 2015 were reviewed. Inclusion criteria included patients who underwent (1) primary ACL reconstruction, (2) use of a hybrid HS autograft with allograft augmentation, and (3) had a minimum 2-year postoperative follow-up. Patients with revision ACL, multiligamentous injuries, all-epiphyseal fixation techniques, or additional procedures beyond chondroplasty or meniscal repair/debridement were excluded. Data collected included demographics, graft size, concomitant procedures, revision operation, revision ACL reconstruction, and patient-reported outcomes. RESULTS: In total, 59 patients met criteria for inclusion into the hybrid group, and 80 patients were eligible for inclusion into the control group. The average age of the cohort was 22.9 (interquartile range Q1:17, Q3: 38.3), and 51.8% of the patients were female. Seven patients (11.9%) in the hybrid ACL group underwent revision ACL surgery versus 15 (18.8%) in the control group (P = .27). There was no difference in patient-reported outcomes between groups. CONCLUSIONS: Augmenting an HS ACL autograft that is 8 mm or less with allograft tissue to increase the overall size of the ACL graft shows no difference in overall reoperation or revision of ACL failure. The hybrid autograft/allograft ACL reconstruction patients showed no clinically important difference between groups in patient-reported outcome measures. LEVEL OF EVIDENCE: Level III, case-control comparative analysis.

BACKGROUND: Complications after total knee arthroplasty (TKA) are devastating for patients, and surgeons are held accountable in alternative payment models. Optimization of modifiable risk factors has become a mainstay in the preoperative period. We sought to evaluate the consequence of failure to optimize key risk factors in a modern cohort of patients who underwent TKA. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was searched to identify patients who underwent TKA in 2017-2018. Patients were considered optimized if they had a body mass index <40kg/m2, had albumin >3.5g/dL, were nonsmokers, and were nondiabetic. Patients were then grouped based on the previous 4 risk factors. Thirty-day readmission, infection, general complications, and mortality were analyzed and compared between the groups. RESULTS: Overall, 84,315 patients were included in the study. A total of 31.6% of patients were not considered optimized. Body mass index >40kg/m2, albumin <3.5, smoking, and insulin-dependent diabetes were all found to be associated with postoperative infection, readmission, mortality, and complication in general (P < .05). When compared, the nonoptimized group was found to have significantly higher risk of readmission (5 vs 3%), infection (2 vs 1%), general complications (8 vs 5%), and mortality (0.35 vs 0.1%) (all P < .001). Logistic regression showed that those with albumin less than 3.5g/dL had 3.7-fold higher odds of infection and 7.2-fold higher odds of 30-day mortality. CONCLUSION: Despite knowledge that modifiable risk factors significantly influence postoperative outcomes, surgeons continue to operate on patients who are not optimized. Among the modifiable risk factors analyzed, hypoalbuminemia appears to be the strongest risk factor for all complications evaluated. Special attention should be paid to preoperative nutritional optimization. LEVEL OF EVIDENCE: Retrospective cohort study, level IV.

BACKGROUND: Obese patients have increased complications after total knee arthroplasty (TKA). A body mass index (BMI) cutoff of 40 is frequently used to determine eligibility for TKA. Patients with a BMI <40 and extremely large legs which may predispose them to complications are approved for surgery because they fall below this cutoff. Alternatively, patients with truncal obesity and a BMI >40 are accepted because they have thin legs. We sought to determine whether BMI or girth should be used to determine eligibility. METHODS: 453 patients who underwent TKA were included. A lower extremity girth (LEG) ratio was calculated dividing the width of the soft tissue envelope by bone width on lateral radiographs. Receiver operator curves were generated to predict 90-day complications. RESULTS: There was no difference in median LEG ratio between patients with or without a complication (P = .08). Receiver operator curves indicated that size of the soft tissue envelope had no utility in predicting complications. There was no correlation between LEG ratio and specific complications such as infection, malalignment, or wound complications. Using a LEG ratio threshold of 4.834, the sensitivity and specificity for predicting complications were 48% and 64%, respectively. The median BMI for patients with no complication was 32.3 and 35 for patients with a complication (P = .07). CONCLUSION: Complications are not necessarily associated with size of the soft tissue envelope in TKA.Decisions concerning TKA should not be made solely on the size of a patient's leg. LEVEL OF EVIDENCE: Level III (retrospective comparative study).

PURPOSE: To evaluate the tibiofemoral contact mechanics of an all-inside posterior medial meniscal root repair technique via suture fixation to the posterior cruciate ligament (PCL) and to compare with that of the intact knee and the knee with a root tear. METHODS: Tibiofemoral contact mechanics were recorded in 8 human cadaveric knee specimens using pressure sensors. Each knee underwent 3 testing conditions related to the posterior medial meniscal root: (1) intact knee; (2) root tear; and (3) all-inside repair via suture fixation to the PCL. Knees were loaded with a 1000-N axial compressive force at 4 knee flexion angles (0°, 30°, 60°, 90°). Calculations were performed for contact area, mean contact pressure, and peak contact pressure. A generalized linear model with a Tukey adjusted least square means test was used to determine differences between testing conditions. RESULTS: Across all knee flexion angles, there was an overall mean 26.3% reduction in contact area with root tear (211.34 mm2 vs intact 286.64 mm2, P = .0002), and a 31.6% increase from root tear to repair (277.61 mm2, P = .0297). Across all knee flexion angles, there was an overall mean 24.3% increase in contact pressure with root tear (1849.12 N/mm2 vs. intact 1487.52 N/mm2, P < .0001), and a 31.1% decrease from root tear to repair (1410.7 N/mm2, P = .0037). Across all knee flexion angles, there was an overall mean 10.6% increase in peak contact pressure with root tear (4083.55 N/mm2 vs. intact 3693.68 N/mm2, P < .0001), and a 12.4% decrease from root tear to repair (3632.13 N/mm2, P = .531). CONCLUSIONS: In most testing conditions and with overall averaging across knee flexion angles, the all-inside posterior medial meniscal root repair with suture fixation to the adjacent PCL fibers restored contact area (from 26.3% reduction with root tear to 31.6% increase with repair), contact pressures (from 24.3% increase with root tear to 31.1% decrease with repair), and peak contact pressures (from 10.6% increase with root tear to 12.4% decrease with repair) to that of the intact knee This may be a future potential technique to limit complications associated with the traditional transtibial pull-out method of repair. CLINICAL RELEVANCE: This technique may provide a posterior medial meniscal root repair construct that restores most tibiofemoral contact mechanics and offers theoretical benefits of technical ease and potential for an acceptable, less "anatomic" repair location.

BACKGROUND: We implemented a risk assessment tool (RAT) used by clinical navigators to quantify pre-operative mobility, home safety, social/cognitive barriers, and patient health history. We sought to determine if this RAT is associated with the need for post-acute care (PAC) services defined as inpatient rehabilitation and skilled nursing facility, home health, and none (home) following total joint arthroplasty. METHODS: The study sample comprised of a total of 1438 primary TJA patients included in a bundled payment model. The RAT score, which ranges from 0 to 100, with higher scores representing healthier, more independent patents, was the key independent variable and post-acute service was the primary outcome variable. RESULTS: The median RAT score was 83 (interquartile range 78-87.5) for no PAC discharges compared to 74 (interquartile range 67-81) for inpatient PAC discharges (P < .0001). After adjusting for the effects of length of hospital stay, surgery type, and patient gender, there was 6× increased odds of inpatient PAC for higher risk patients compared to low risk patients. A RAT score of 74 predicts discharges without PAC 87% of the time. CONCLUSION: The RAT that is based on psychosocial, cognitive, environmental factors, and health status was significantly associated with the need for PAC services. The next step is to build and validate a real time, risk adjustment model to assist physicians and patients with planning post-discharge resources.

BACKGROUND: Extensive femoral bone loss poses a challenge in revision total hip arthroplasty (rTHA). Many techniques have been developed to address this problem including fully porous cylindrical stems, impaction bone grafting, and cementation of long stems, which have had varied success. Modular tapered fluted femoral stems (MTFS) show favorable results. We sought to determine the minimum 2-year radiographic and clinical performance of MTFS in rTHA in a population with extensive proximal femoral bone loss. METHODS: Our clinical database was queried retrospectively for all patients who underwent rTHA with an MTFS. We included patients with Paprosky 3 and 4 femoral bone loss and patients with Vancouver B2 and B3 periprosthetic femur fractures. Patients without 2-year follow-up were invited to return to clinic for X-ray evaluation and to complete clinical questionnaires. We assessed distance of stem subsidence and presence of stem fixation on final X-ray. We recorded all-cause revision and survival of the stem at final follow-up. RESULTS: One hundred twenty-nine patients were available for follow-up. Average follow-up time was 3.75 years. One hundred twenty-two stems (95%) remained in place at final follow-up. Median subsidence was 1.4 mm (range 0-21). All-cause revision rate was 16.3% (21 patients). Of the hips revised, 10 were for instability, 6 for infection, 1 for aseptic loosening, and 1 for periprosthetic femur fracture. Three were revised for other reasons. The stem was revised in 7 patients (5.4%), and the most common reason for stem revision was infection (5 patients). The other 2 stems were revised for aseptic loosening in a Paprosky 4 femur and periprosthetic femur fracture. Survival of tapered modular fluted stems with aseptic failure as an endpoint was 98.4%. The mean Hip disability and Osteoarthritis Outcome Score, Joint Replacement score at final follow-up was 73, and mean Veterans Rand 12 item health survey physical and mental scores were 32.8 and 52.2, respectively. CONCLUSION: In patients with Paprosky 3, 4 femoral defects or Vancouver type B2, B3 fractures, modular tapered fluted stems for femoral revision show excellent outcomes at minimum 2-year follow-up.

BACKGROUND: Advances in technique and perioperative blood management have improved transfusion rates following unilateral primary total joint arthroplasty and led some centers to change their preoperative blood ordering protocols. The purpose of this study is to determine whether deleting type and screens (T&S) from preoperative order sets was safe for patients undergoing primary total knee (TKA) and total hip arthroplasty (THA) and to identify patients who required allogenic blood transfusion. METHODS: Prospectively collected data were reviewed to identify any patient with a hemoglobin (Hgb) drawn within 30 days of surgery who received a transfusion following a unilateral primary TKA or THA. RESULTS: A total of 1255 patients met inclusion criteria. Of the total, 682 (54%) were TKAs and 573 (46%) were THAs. The mean preoperative Hgb was 11.5 g/dL with an average delta Hgb of 3.6 g/dL on postoperative day 1. No patient required an intraoperative transfusion. Fourteen patients (mean age and body mass index, 67.9 and 29.0) required a transfusion (1.1%) for postoperative blood loss anemia. Of those transfused, 13 (93%) of the patients underwent THA with the mean estimated blood loss of 378.6 mL. The total cost for a patient obtaining a T&S is $191.27. CONCLUSION: In our series, the risk of blood transfusion was rare (1.1%) and occurred only secondary to postoperative blood loss anemia. There were no cases of intraoperative complication requiring urgent or emergent blood transfusion. Removing T&S from standard order sets for patients undergoing primary TKA or THA appears to be a safe and cost-effective practice.
