RESUMEN
OBJECTIVES: To compare 1-year revision rates among left-sided and right-sided intertrochanteric femur fractures. DESIGN: Retrospective. SETTING: 120+ contributing centers to multicentered database. PATIENT SELECTION CRITERIA: Patients who sustained intertrochanteric femur fracture (ITFF) and had a cephalomedullary nail (CMN) from 2015 to 2022 were identified. Patients were then stratified based on left-sided or right-sided fracture. Patients were excluded if younger than 18 years with <1-year follow-up. The intervention investigated was CMN on left or right side. OUTCOME MEASURES AND COMPARISONS: One-year revision surgery, comparing CMN performed on left or right side for ITFFs. RESULTS: In total, 113,626 patients met inclusion criteria, with 55,295 in the right-sided cohort and 58,331 in the left-sided cohort. There was no difference between cohorts with respect to age, gender, diabetes, osteoporosis, chronic kidney disease, or congestive heart failure (P > 0.05 for all). Patients who sustained a left ITFF and treated with a CMN were more likely to have revision surgery at 1 year (Left: 1.24%, Right: 0.90%; OR: 1.24; 95% confidence interval [CI], 1.15-1.1.33) or develop a nonunion or malunion (Left: 1.30%, Right: 0.98%; OR: 1.31; 95% CI, 1.14-1.52). The most common revision surgery conducted for both cohorts was conversion total hip arthroplasty (Left: 70.4% and Right: 70.0%). CONCLUSIONS: Patients who sustained a left intertrochanteric femur fracture and were treated with a CMN were more likely to undergo revision at 1 year due to nonunion. There were no differences in demographics and comorbidities between cohorts. Though left-sided versus right-sided confounding variables may exist, the difference in nonunion rate may be explained by clockwise torque of the lag screw used in most implants. Increased awareness, implant design, and improved technique during fracture reduction and fixation may help lower this disproportionate nonunion rate and its associated morbidity and financial impact. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

INTRODUCTION: Preoperative anemia is an independent risk factor of complications after primary total hip arthroplasty (THA). Currently used hemoglobin thresholds are not developed for risk stratification of arthroplasty patients and do not provide surgery-specific information on postoperative complication risk. Thus, we aimed to calculate THA-specific preoperative hemoglobin strata that observe the likelihood of 90-day blood transfusion and determine whether these strata are associated with increased risk of 90-day complications and 2-year prosthetic joint infection (PJI). METHODS: A retrospective cohort analysis identified 56,101 patients who underwent primary THA from 2013 to 2022. Using the lowest hemoglobin value for each patient one month before THA, stratum-specific likelihood ratio (SSLR) analysis calculated sex-based hemoglobin strata associated with the likelihood of 90-day postoperative blood transfusion. Propensity score matching was performed. Incidence rates and risk of 90-day major complications and 2-year PJI were observed for each identified preoperative hemoglobin stratum. RESULTS: SSLR analysis identified five male (strata, likelihood ratio [<10.4 g/dL, 12.5; 10.5 to 11.4 g/dL, 8.0; 11.5 to 12.4 g/dL, 2.4; 12.5 to 13.4 g/dL, 1.3; 13.5 to 13.9 g/dL, 0.5]) and five female (<8.9 g/dL, 10.7; 9.0 to 10.9 g/dL, 4.0; 11.0 to 11.4 g/dL, 2.0; 12.0 to 12.9 g/dL, 1.0; 13.0 to 13.4 g/dL, 0.6) preoperative hemoglobin strata associated with varying likelihoods of 90-day blood transfusion after THA. After matching in both male and female cohorts, as the calculated preoperative hemoglobin strata decreased, the relative risk of overall 90-day major complications and 2-year PJI increased incrementally (all P < 0.05). CONCLUSION: SSLR analysis established THA-specific sex-based preoperative hemoglobin strata that observe the likelihood of 90-day blood transfusion and predict the risk of 90-day medical complications and 2-year PJI. These strata are a first of their kind in THA research. While preoperatively optimizing patients, we recommend using these hemoglobin thresholds to help guide decisions on presurgery anemia optimization and to reduce the need for postoperative blood transfusion. LEVEL OF EVIDENCE: Level III.
RESUMEN
BACKGROUND: Venous thromboembolism (VTE) is a feared complication of joint arthroplasty, leading to recent clinical practice guidelines aimed at VTE prevention and prophylaxis. However, limited studies have examined national changes in practice regarding chemoprophylaxis and the resultant changes in VTE rates. The purpose of this study was to identify: (1) the temporal trends in thrombotic complications; and (2) changes in chemoprophylaxis utilization in patients undergoing elective total knee arthroplasty (TKA). METHODS: A retrospective study was conducted using a large all-payer claims dataset. Patients who underwent osteoarthritis-indicated TKA between 2011 and 2020 were identified. Annual rates of VTE, including deep vein thrombosis and pulmonary embolism, within 90 days of TKA were determined. Utilization patterns for postoperative aspirin and anticoagulant medications were observed. Temporal trends were analyzed with linear regression and the calculation of the cumulative annual growth rate. Multivariable logistic regression was conducted to account for the effects of age and comorbidities. RESULTS: A total of 1,263,351 TKA patients were identified between 2011 and 2020. There were significant reductions in VTE rates (2.9% in 2011 to 1.8% in 2020), deep vein thrombosis rates (2.0% in 2011 to 1.3% in 2020), and pulmonary embolism rates (1.1% in 2011 to 0.6% in 2020). Postoperative utilization of aspirin increased from 5.9% in 2011 to 53.2% in 2020, whereas utilization of anticoagulants decreased from 94.1% in 2011 to 46.8% in 2020. Among anticoagulants, direct factor Xa inhibitors had the greatest increase in utilization (4.6 to 69.7%). The average reimbursement associated with VTE after TKA decreased from $18,061 in 2011 to $7,835 in 2020. CONCLUSIONS: The incidence rate and economic burden of VTE after TKA have significantly declined since 2011. There has been a trend toward increased aspirin and direct oral anticoagulant utilization for postoperative chemoprophylaxis. LEVEL OF EVIDENCE: Level III.
RESUMEN
INTRODUCTION: Preoperative anemia is associated with increased postoperative transfusion and complication rates after total knee arthroplasty (TKA). We aimed to create TKA-specific data-driven preoperative hemoglobin strata that quantify the likelihood of 90-day postoperative blood transfusion and evaluate whether these strata are associated with increased risk of 90-day major complications and 2-year prosthetic joint infection (PJI). METHODS: Primary TKA patients from 2013 to 2022 were identified using a national database. Stratum-specific likelihood ratio (SSLR) analysis defined hemoglobin strata associated with the risk of 90-day blood transfusion. Each stratum was propensity score matched to the highest identified hemoglobin strata. Unmatched incidence rates and matched risk of 90-day major complications and 2-year PJI between strata were compared. RESULTS: SSLR identified four 90-day blood transfusion hemoglobin strata for men (strata [g/dL], likelihood ratio [<11.4, 8.06; 11.5 to 11.9, 4.34; 12.0 to 12.9, 1.70; 13.0 to 17.0, 0.54]) and women (<10.4, 8.22; 10.5 to 11.4, 2.84; 11.5 to 12.4, 1.38; 12.5 to 17.0, 0.50). Increased 2-year PJI risk was associated with three male strata (<11.4, 11.5 to 11.9, 12.0 to 12.9; all P < 0.001) and three female strata (<10.4, 10.5 to 11.4, 11.5 to 12.4; all P < 0.001). Increased 90-day major complication risk was associated with three male strata (<11.4, 11.5 to 11.9, 12.0 to 12.9; all P < 0.001) and three female strata (<10.4, 10.5 to 11.4, 11.5 to 12.4; all P < 0.001). CONCLUSIONS: Using SSLR analysis, we identified unique TKA-specific data-driven hemoglobin strata for both men and women that quantify the likelihood of 90-day blood transfusions and predict the risk of both 90-day major complications and 2-year PJI. These strata are a first in the TKA literature and can assist surgeons in stratifying patients' transfusion and complication risk based on their preoperative hemoglobin value. While optimizing patients in the preoperative setting, we recommend using these TKA-specific hemoglobin thresholds to help guide decision making on the need for presurgery anemia optimization and to help reduce the need for blood transfusion.
RESUMEN
Background Cold weather in the first few months of life may increase the risk of a late diagnosis of developmental dysplasia of the hip (DDH). Early detection of DDH can often be treated non-surgically. The purpose of this study is to observe whether the rates of surgical intervention for DDH differ based on average outdoor temperatures in the winter months. Methods A retrospective observational study of DDH patients diagnosed from 2010 to 2021 was conducted using a national administrative database. Five geographic regions were defined based on the average temperatures in the coldest quarter of the year. The rates of DDH-related surgeries were compared across these temperature regions. Results A total of 55,911 patients ≤5 years old with a DDH diagnosis from 2010 to 2021 were identified in the database. When compared to the warmest region (Group 5), the coldest region (Group 1) had higher rates of open reduction (4.59% vs. 2.06%, p<0.001), adductor tenotomy (6.95% vs. 2.91%, p<0.001), femoral osteotomy (5.75% vs. 2.04%, p<0.001), pelvic osteotomy (5.27% vs. 2.04%, p<0.001), and total DDH surgeries (11.42% vs. 5.03%, p<0.001). Conclusion Children living in states with an average winter temperature of -6.17°C had an increased likelihood of requiring surgical intervention for DDH within the first five years of life.
RESUMEN
BACKGROUND: Modern cementless total knee arthroplasty (TKA) fixation has shown comparable long-term outcomes to cemented TKA, but the trend of using cementless TKA remains unclear. This study aimed to investigate the trend of using cementless TKA based on a national database. METHODS: The patients undergoing cementless TKA between 2015 and 2021 were retrospectively extracted from the PearlDiver (Mariner dataset) Database. The annual percentage of cementless TKA was calculated using the following formula: annual number of cementless TKA/annual number of TKA. The trend of the number of patients undergoing cementless TKA was created according to a compounded annual growth rate (CAGR) calculation of annual percentages. Patient age, comorbidity, region, insurance type, etc., were also investigated. Differences were considered statistically significant at P < 0.05. RESULTS: Of the 574,848 patients who received TKA, 546,731 (95%) underwent cemented fixation and 28,117 (5%) underwent cementless fixation. From 2015 to 2021, the use of cementless TKA significantly increased by 242% from 3 to 9% (compounded annual growth rate (CAGR): + 20%; P < 0.05). From 2015 to 2021, we observed a CAGR greater than 15% for all age groups (< 50, 50-59, 60-69, 70-74, 75 +), insurance types (cash, commercial, government, Medicare, Medicaid), regions (Midwest, Northeast, South, West), sex (male and female), and certain comorbidities (osteoporosis, diabetes mellitus, tobacco use, underweight (BMI < 18.5), rheumatoid arthritis) (P < 0.05 for all). Patients undergoing TKA with chronic kidney disease, prior fragility fractures, and dementia demonstrated a CAGR of + 9%-13% from 2015 to 2021 (P < 0.05). CONCLUSION: From 2015 to 2021, the use of cementless TKA saw a dramatic increase in all patient populations. However, there is still no consensus on when to cement and in whom. Clinical practice guidelines are needed to ensure safe and effective use of cementless fixation.
RESUMEN
BACKGROUND: Total knee arthroplasty (TKA) for solid organ transplant (SOT) patients is becoming more prominent as life expectancy in this population increases. However, data on long-term (10 year) implant survivorship in this cohort are sparse. The purpose of this study was to compare 90-day, 2-year, 5-year, and 10-year implant survivability following primary TKA in patients who did and did not have prior SOT. METHODS: The PearlDiver database was utilized to query patients who underwent unilateral elective TKA with at least 2 years of active follow-up. These patients were stratified into those who had a SOT before TKA and those who did not. The SOT cohort was propensity-matched to control patients based on age, sex, Charlson Comorbidity Index, and obesity in a 1:2 ratio. Cumulative incidence rates and hazard ratios (HRs) were compared between the SOT, matched, and unmatched cohorts. RESULTS: No difference was observed in 10-year cumulative incidence and risk of all-cause revision surgery in TKA patients with prior SOT when compared to matched and unmatched controls. Compared to the matched control, the SOT cohort had no difference in the risk of revision when stratified by indication and timing. However, when compared to the unmatched control, patients who had prior SOT had a higher risk for revision due to periprosthetic joint infection at 10 years (HR: 1.80; 95% confidence interval: 1.17 to 2.76) as well as all-cause revision within 90 days after TKA (HR: 1.93; 95% confidence interval: 1.10 to 3.36). CONCLUSIONS: Prior SOT patients have higher rates of all-cause revision within 90 days and periprosthetic joint infection within 10 years when compared to the general population, likely associated with the elevated number of comorbidities in SOT patients and not the transplant itself. Therefore, these patients should be monitored in the preoperative and early postoperative settings to optimize their known comorbidities.

BACKGROUND: Bariatric surgery (BS) is indicated for select class III obesity patients undergoing total knee arthroplasty (TKA) to reduce obesity-related complications. This study assessed the effect of BS on TKA revision rates compared to the general population and class III obesity patients without a history of BS. METHODS: A national database identified patients who had primary TKA. They were divided into two groups: those with BS prior to TKA and those without. Patients without BS formed two control groups, a matched general population, and a matched class III obese cohort. The BS group was matched with controls based on age, Charlson Comorbidity Index (CCI), gender, and diabetes mellitus. Revision rates were analyzed using Kaplan-Meier survival analysis and hazard ratios (HR), calculated using Cox proportional hazard modeling. RESULTS: 14,292 BS patients were compared to 57,006 matched general population controls, and 19,504 BS patients were compared to 77,846 matched class III obesity control patients. BS patients had a higher risk of 5-year all-cause revision (HR: 1.13; P = 0.014) and revision due to periprosthetic fracture (HR: 1.39; P < 0.001) compared to the general population. Compared to class III obesity controls, BS patients had a lower risk of 5-year revision due to prosthetic joint infection (HR: 0.77; P = 0.001), with no difference in all-cause revision (P = 0.362). CONCLUSION: BS does not reduce all-cause TKA revision risk compared to the general or matched class III obesity population. However, it lowers the risk of revision due to prosthetic joint infection when compared to patients with class III obesity. LEVEL OF EVIDENCE: IV.

BACKGROUND: Certain medications interfere with the bone remodeling process and may potentially increase the risk of complications after total knee arthroplasty (TKA). As patients undergoing TKA may be taking these bone mineral density (BMD)-reducing medications, it is unclear as to whether and which medications impact TKA outcomes. Therefore, the purpose of this study was to observe the impact of various BMD-reducing medications on 2-year implant-related complications following TKA. METHODS: A retrospective analysis of patients undergoing primary TKA was conducted using a national administrative claims database. Patients were identified if they were taking any known BMD-reducing medication and were compared to control patients. To control for confounders associated with taking multiple agents, multivariable logistic regression analyses were conducted for each 2-year outcome (all-cause revision, loosening-indicated revision, and periprosthetic fracture--indicated revision), with the output recorded as odds ratios (ORs). RESULTS: In our study, 502,927 of 1,276,209 TKA patients (39.4%) were taking at least one BMD-reducing medication perioperatively. On multivariable analysis, medications associated with a higher likelihood of 2-year all-cause revision included first- and second-generation antipsychotics (SGAs) (OR: 1.42 and 1.26, respectively), selective serotonin reuptake inhibitors (SSRIs) (OR: 1.14), glucocorticoids (1.13), and proton pump inhibitors (PPIs) (OR: 1.23) (P < .05 for all). Medications associated with a higher likelihood of 2-year periprosthetic fracture included SGAs (OR: 1.51), SSRIs (OR: 1.27), aromatase inhibitors (OR: 1.29), and PPIs (OR: 1.42) (P < .05 for all). CONCLUSIONS: Of the drug classes observed, the utilization of perioperative PPIs, SSRIs, glucocorticoids, first-generation antipsychotics, and SGAs was associated with the highest odds of all-cause revision. Our findings suggest a relationship between these medications and BMD-related complications; however, further studies should seek to determine the causality of these relationships.
RESUMEN
BACKGROUND: Postoperative infection, aseptic loosening, and perioperative medical complications after total ankle arthroplasty (TAA) are all devastating problems. While previous studies have shown diabetes as a risk factor predisposing patients to postoperative complications, not all literature supports this association following TAA. The goal of this study is to determine if diabetes influences midterm outcomes following TAA. METHODS: An insurance database was utilized to identify patients undergoing TAA for ankle arthritis with a concurrent diagnosis of diabetes based on Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10), diagnosis and procedure codes from 2010 to 2021. The postoperative outcomes of all-cause revision, periprosthetic joint infection (PJI), septic revision, and aseptic revision were compared between patients with and without diabetes with a minimum 2-year follow-up using Kaplan-Meier and multivariate Cox proportional hazards analyses. Patient demographics, comorbidities, and Charlson Comorbidity Index were analyzed via univariate and multivariate analysis. RESULTS: The study population included 8317 patients, 345 (4.1%) of whom had a concurrent diabetes diagnosis, who underwent TAA. After multivariate Cox proportional hazards analysis, the 5-year cumulative incidence of being coded as having PJI was 7.3% in patients with known diabetes compared to 3.9% in patients without known diabetes, with a 95% increased risk (hazard ratio [HR] 1.95, 95% CI 1.15-3.30, P = .01). Patients with diabetes also demonstrated a 5-year cumulative incidence of septic revision of 1.4% compared to 0.4% in those without, with a 363% increased risk (HR 4.63, 95% CI 1.22-17.52, P = .02). However, there was no difference in the 5-year cumulative incidence of all-cause revision TAA with 4.6% in patients with diabetes and 4.3% in those without (HR 1.29, 95% CI 0.69-2.44, P = .42). CONCLUSION: In this database, the 5-year risk of PJI and septic revision was higher among patients with diabetes compared to those without, but cumulative incidence of all-cause revision TAA was not different between groups. LEVEL OF EVIDENCE: Level III, retrospective cohort database study.
RESUMEN
BACKGROUND: In patients considered high-risk for infection, extended oral antibiotic (EOA) prophylaxis has been demonstrated to reduce rates of prosthetic joint infection following total hip arthroplasty (THA). Although national guidelines regarding their use have not yet been created, the increase in literature surrounding EOA prophylaxis suggests a potential change in practice patterns. The purpose of this study was to investigate the trends in utilization of EOA prophylaxis following THA from 2010 to 2022 and identify prescription patterns. METHODS: A total of 646,059 primary THA and 51,879 aseptic revision THA patients were included in this study. Patients who underwent primary or aseptic revision THA between 2010 and 2022 were identified in a national administrative claims database. Rates and duration of EOA prescriptions were calculated. A secondary analysis examined rates of utilization across demographics, including patients considered high risk for infection. RESULTS: From 2010 to 2022, utilization of EOA increased by 366% and 298% following primary and revision THA, respectively. Of patients prescribed postoperative antibiotics, 30% and 59% were prescribed antibiotics for more than 7 days following primary and revision THA, respectively. Rates of utilization were similar between high-risk individuals and the general population. CONCLUSIONS: Rates of utilization of EOA prophylaxis after THA have increased significantly since 2010. As current trends demonstrate a wide variation in prescription patterns, including in length of antibiotic duration and in patient population prescribed, guidelines surrounding the use of EOA prophylaxis after THA are necessary to promote antibiotic stewardship while preventing rates of periprosthetic joint infection.

BACKGROUND: This study identifies data-driven strata for preoperative Hemoglobin A1c (HbA1c) and same-day glucose levels that maximize differences in the likelihood of complications following total hip arthroplasty (THA). METHODS: Patients who underwent THA from 2013 to 2022 were identified using a national database. In total, 18,728 patients were identified with a mean age of 67 years (range, 18 to 80). Stratum specific likelihood ratio (SSLR) analysis determined separate strata for HbA1c and same-day glucose levels that minimized the likelihood of 90-day complications following THA. Each stratum was propensity-score matched based on age, sex, hypertension, heart failure, chronic obstructive pulmonary disease, and obesity to the lowest respective stratum. The risk ratio (RR) with respect to the lowest matched stratum was observed. RESULTS: Our SSLR analysis identified 3 data-driven HbA1c strata (4.5 to 5.9, 6.0 to 6.9, and 7.0+) and two same-day glucose strata (60 to 189 and 190+) that predicted 90-day major complications. For HbA1c, when compared to the lowest strata (4.5 to 5.9), the risk of 90-day major complications sequentially increased as the HbA1c strata increased: 6.0 to 6.9 (RR: 1.21; P = .041), 7+ (RR: 1.82; P < .001). For same-day glucose, when compared to the matched lowest strata (60 to 189), the risk of 90-day major complications was higher for the 190+ strata (RR: 1.5; P < .001). CONCLUSIONS: Our results support the use of multiple HbA1c strata that can be incorporated into preoperative risk-stratification models. Additionally, we identified a single cut-off level of 190 as a maximum target blood glucose level perioperatively.

Orthopaedic surgery lags in recruiting women and under-represented minorities (URMs). In addition, women and URMs hold fewer leadership roles across orthopaedic subspecialties. This inequity is geographically heterogeneous, with female URM residents and attendings being more concentrated in some areas of the country. For instance, practicing female orthopaedic surgeons are more prevalent in Northeast and Pacific programs. Mentorship and representation in leadership positions play a notable role in trainee recruitment. Video communication platforms offer a novel mechanism to reach historically under-represented students across the country. We reviewed five established mentorship programs focused on women and URMs. Each program emphasized a longitudinal relationship between mentors and mentees. In reviewing these programs, we sought to identify the successful components of each program. Leveraging and integrating effective components already established by conventional mentorship programs into virtual programming will aid in optimizing those programs and improve geographic equity in access to mentorship resources. It is critical to extend the principles of successful mentorship programs to technology-enabled programs moving forward.

BACKGROUND: In osteoporotic patients, surgeons may utilize cemented femoral fixation to minimize risk of fracture. The purpose of this study was to compare 5-year implant survivability in patients who have osteoporosis who underwent elective total hip arthroplasty (THA) with cementless versus cemented fixation. METHODS: A retrospective analysis of patients who have osteoporosis undergoing THA with either cemented or cementless femoral fixation was conducted using a national administrative claims database. Of the 18,431 identified THA patients who have osteoporosis, 15,867 (86.1%) underwent cementless fixation. The primary outcome was a comparison of the 5-year cumulative incidences of aseptic revision, mechanical loosening, and periprosthetic fracture (PPF). Kaplan-Meier and Multivariable Cox Proportional Hazard Ratio analyses were used, controlling for femoral fixation method, age, sex, a comorbidity scale, use of osteoporosis medication, and important comorbidity. RESULTS: There was no difference in aseptic revision (Hazard's Ratio (HR): 1.13; 95% Confidence Interval (CI): 0.79 to 1.62; P value: .500) and PPF (HR: 0.96; 95% CI: 0.64 to 1.44; P value: .858) within 5 years of THA between fixation cohorts. However, patients who had cemented fixation were more likely to suffer mechanical loosening with 5 years post-THA (HR: 1.79; 95% CI: 1.17 to 2.71; P-value: .007). CONCLUSIONS: We found a similar 5-year rate of PPF when comparing patients who underwent cementless versus cemented femoral fixation for elective THA regardless of preoperative diagnosis of osteoporosis. While existing registry data support the use of cemented fixation in elderly patients, a more thorough understanding of the interplay between age, osteoporosis, and implant design is needed to delineate in whom cemented fixation is most warranted for PPF prevention.
RESUMEN
INTRODUCTION: Spinal anesthesia (SA) allows total joint arthroplasty to be done while minimizing opioids and systemic anesthetic agents compared with general anesthesia (GA). SA has been associated with shortened postoperative recovery; however, the relationship between SA, major postoperative complications, and pneumonia (PNA) remains unclear. METHODS: Patients in a large, national database who underwent total hip arthroplasty or total knee arthroplasty from 2010 to 2020 were identified. 1:1 propensity score matching was used to create matched groups of patients who underwent SA and GA. The groups were matched by age, sex, chronic obstructive pulmonary disease, smoking status, Charlson Comorbidity Index, and American Society of Anesthesiology (ASA) classification. 1:1 matching was also done among the ASA classifications as a subanalysis. RESULTS: Overall, equally matched groups of 217,267 patients who underwent SA versus GA were identified. 850 patients (0.39%) developed postoperative PNA after GA versus 544 patients (0.25%) after SA ( P < 0.001). The risk of major complications was 6,922 (3.2%) in the GA group and 5,401 (2.5%) in the SA group ( P < 0.001). Similarly, the risk of unplanned postoperative reintubation was higher (0.18% versus 0.10%, P < 0.001) and mortality was higher (0.14% versus 0.09%, P < 0.001) in the GA group than in the SA group. In ASA 1 to 3 patients, the risk of PNA was 0.08% to 0.21% higher with GA than with SA. In ASA 4 patients, the risk of PNA was 0.42% higher in SA than in GA (1.92% versus 1.5%, P < 0.001) and the mortality rate was nearly doubled in GA than in SA (1.46% versus 0.77%, P = 0.017). DISCUSSION: Overall, GA was associated with a small but markedly higher rate of major complications, mortality, and PNA than SA in patients undergoing total joint arthroplasty when matching for differences in comorbidities.

BACKGROUND: Increasing numbers of residency applications create challenges for applicants and residency programs to assess if they are a good fit during the residency application and match process. Applicants face limited or conflicting information as they assess programs, leading to overapplying. A holistic review of residency applications is considered a gold standard for programs, but the current volumes and associated time constraints leave programs relying on numerical filters, which do not predict success in residency. Applicants could benefit from increased transparency in the residency application process. OBJECTIVE: This study aims to determine the information applicants find most beneficial from residency programs when deciding where to apply, by type of medical school education background. METHODS: Match 2023 applicants voluntarily completed an anonymous survey through the Twitter and Instagram social media platforms. We asked the respondents to select 3 top factors from a multiple-choice list of what information they would like from residency programs to help determine if the characteristics of their application align with program values. We examined differences in helpful factors selected by medical school backgrounds using ANOVA. RESULTS: There were 4649 survey respondents. When responses were analyzed by United States-allopathic (US-MD), doctor of osteopathic medicine (DO), and international medical graduate (IMG) educational backgrounds, respondents chose different factors as most helpful: minimum United States Medical Licensing Examination (USMLE) or Comprehensive Osteopathic Medical Licensing Examination (COMLEX) Step 2 scores (565/3042, 18.57% US-MD; 485/3042, 15.9% DO; and 1992/3042, 65.48% IMG; P<.001), resident hometown region (281/1132, 24.82% US-MD; 189/1132, 16.7% DO; and 662/1132, 58.48% IMG; P=.02), resident medical school region (476/2179, 22% US-MD; 250/2179, 11.5% DO; and 1453/2179, 66.7% IMG; P=.002), and percent of residents or attendings underrepresented in medicine (417/1815, 22.98% US-MD; 158/1815, 8.71% DO; and 1240/1815, 68.32% IMG; P<.001). CONCLUSIONS: When applying to residency programs, this study found that the factors that respondents consider most helpful from programs in deciding where to apply differ by educational background. Across all educational groups, respondents want transparency around standardized exam scores, geography, and the racial or ethnic backgrounds of residents and attendings.
RESUMEN
BACKGROUND: TikTok is a popular platform that can be used for medical insights. However, spreading inaccurate information about diagnosing or treating medical conditions can undermine the quality of patient care. Our assessment focused on the discourse surrounding knee osteoarthritis on TikTok, with two primary objectives: 1) identifying the creators behind osteoarthritis-related content, and 2) examining whether a connection exists between the reach of video content and the strength of recommendations provided. METHODS: The top 100 TikTok videos were chosen based on likes on March 29, 2023. Posts were identified using the hashtag ("#Osteoarthritis"). Videos were classified by the following: number of likes, comments, shares, date of upload, uploader (medical professional, non-medical professional, or business), and video content (medical treatment, home remedy, personal story). Treatments were rated according to the American Academy of Orthopaedic Surgeons (AAOS) Evidence-Based Clinical Practice Guideline for Osteoarthritis using the strength of evidence criteria (1-4 stars). Descriptive and univariate analyses were performed. RESULTS: Among the top videos, 67.7% were uploaded by medical professionals. Private companies, despite having the highest average likes (29,681.2) and shares (1,367.5) per video, had a limited average evidence strength of 2.13. Physician-created videos had the second-highest average number of likes (25,440.1) and shares (1,224.5) per video with a strength of evidence of 3.03. Non-medical professional videos had the lowest evidence support (0.89). Medical treatments, the most liked and shared content, had the lowest evidence strength (1). There was no statistically significant correlation between the number of likes (p=0.808), comments (p=0.647), or shares (p=0.439) to the strength of evidence regarding the intervention. DISCUSSION: TikTok can be unreliable for knee osteoarthritis treatment information. It is common to find non-physicians sharing medical advice on the platform, with medical treatments demonstrating the weakest level of supporting evidence. Orthopaedic surgeons should advise their patients that TikTok treatment recommendations may not align with established guidelines.
RESUMEN
Background: Identifying preoperative risk factors for complications following total shoulder arthroplasty (TSA) has both clinical and financial implications. The purpose of this study was to determine the influence of different degrees of preoperative INR elevation on complications following TSA. Methods: Patients undergoing primary TSA from 2007 to 2018 were identified in a national database. Patients were stratified into 4 cohorts: INR of <1.0, INR of >1.0 to 1.25, INR of >1.25 to 1.5, and INR of >1.5. Postoperative complications were assessed. Multivariate logistic regressions were performed to adjust for differences in demographics and comorbidities among the INR groups. Results: Following adjustment and relative to patients with an INR of <1.0, those with INR of >1.0-1.25, >1.25-1.5, and >1.5 had 1.6-times, 2.4-times, and 2.8-times higher odds of having postoperative bleeding requiring transfusion, respectively (p < 0.05 for all). Relative to patients with INR <1.0, those with INR of > 1.25-1.5 and INR of >1.5 had 7.8-times and 7.0-times higher odds of having pulmonary complications, respectively (p < 0.05 for both). Discussion: With increasing INR levels, there is an independent and step-wise increase in odd ratios for postoperative complications. Current guidelines for preoperative INR thresholds may need to be adjusted for more predictive risk-stratification for TSA. Level of Evidence: III.
RESUMEN
Background Distal radius fractures (DRFs) are the most common fracture of the upper extremity. Given that steroids are one of the most commonly prescribed drugs and are usually prescribed for chronic conditions, steroid use represents a key factor to consider in how to optimize perioperative outcomes. Questions/Purposes The purpose of this study was to investigate if there are differences in perioperative outcomes for patients undergoing DRF open reduction and internal fixation based on preoperative steroid use. Patients and Methods Adult patients who underwent operative treatment for DRF from 2007 to 2018 were identified in a national database. Patients were divided into two cohorts as follows: (1) no steroid usage and (2) preoperative steroid usage. In this analysis, various postoperative complications, as well as extended length of stay and reoperation, were assessed. Bivariate analyses and multivariable logistical regression were performed. Results Among a total of 16,505 patients undergoing operative treatment for DRF, 16,145 patients (97.8%) did not have steroid usage and 360 (2.2%) had steroid usage. Following adjustment, an increased risk of extended length of hospital stay greater than 3 days (odds ratio [OR] = 1.646; p = 0.012) was seen in the steroid usage group compared with those who did not use steroids within 30 days of surgery. Conclusion Preoperative steroid use is associated with increased length of stay over 3 days after DRF open reduction and internal fixation surgery but is not associated with any of the other complications that were assessed in this study. Level of Evidence This is a Level III, retrospective study.
