RESUMEN
BACKGROUND: Patient-reported outcome measures (PROMs) are increasingly used to quantify patient symptomatology when assessing intervention effectiveness as well as to guide patient-centered health-care management and research. Previous studies have analyzed the readability of PROMs used in orthopaedics in the English language; however, the readability of PROMs used in orthopaedics in the Spanish language has not been evaluated. Given the increasing number of Spanish-speaking individuals seeking orthopaedic care in the United States, it is imperative that PROMs are at an adequate reading level for patients to answer appropriately in their native language. This study aimed to assess the readability of publicly available Spanish-language PROMs used in orthopaedics. METHODS: Searches of the PubMed, Google Scholar, and Embase databases were conducted to identify publicly available Spanish-language versions of PROMs used in orthopaedics. Additionally, the PROMIS Health Organization was contacted to obtain Spanish-language versions of the PROMIS (Patient-Reported Outcomes Measurement Information System) questionnaires. A total of 42 Spanish-language PROMs were identified and included in this study. The text of each PROM was inserted into multilingual readability software (legible.es), which analyzed the readability of each PROM using the Fernández Huerta and Índice de Legibilidad de Flesch-Szigriszt (INFLESZ) readability formulas. The mean and standard deviation (SD) of the raw readability scores were calculated for the PROMs. The percentage of PROMs at or below the 6th-grade reading level was also calculated. RESULTS: The mean readability of PROMs using the INFLESZ formula was at a 7th to 10th-grade reading level (mean = 63, SD = 16), and the mean readability using the Fernández Huerta formula was 68 (SD = 15). On average, 57% of the PROMs used in orthopaedics were at or below the INFLESZ 6th-grade readability level. CONCLUSIONS: Approximately half of Spanish-language PROMs used in orthopaedics are written at a reading level that does not meet the National Institutes of Health and the American Medical Association recommendations at or below the 6th-grade level. PROM developers and translators should consider the importance of readability when translating PROMs, to maximize their use and efficacy among orthopaedic patients speaking that language.
RESUMEN
BACKGROUND: Online patient education materials (OPEMs) exist to inform patient medical decisions, yet the average adult in the United States reads at an eighth-grade level and 50% of Medicaid patients read at or below a fifth-grade level. To appropriately meet US health literacy needs, the American Medical Association and National Institutes of Health recommend that patient education materials not exceed a sixth-grade level. The purpose of this study was to assess and compare the readability of English and Spanish online patient education materials pertaining to shoulder instability surgery. METHODS: Google searches of the terms "shoulder instability surgery" and "cirugía de inestabilidad de hombro'' were conducted to include 25 eligible online patient education materials OPEMs per language. English OPEM readability was calculated using Flesch-Kincaid Grade Level, Flesch Reading Ease, Flesch Reading Ease Grade Level, Gunning-Fog Index, Coleman-Liau Index, and Simple Measure of Gobbledygook. Spanish OPEM readability was assessed using Fernandez-Huerta Index (FHI) (the Spanish equivalent of Flesch Reading Ease), FHI Grade Level, Gutiérrez de Polini's Fórmula de comprensibilidad, and INFLESZ. RESULTS: Readability index analysis revealed that the mean Flesch Reading Ease of English online patient education materials was significantly lower than the mean FHI of Spanish online patient education materials. English materials were also found to be written at a significantly higher grade level than Spanish materials. CONCLUSIONS: Shoulder instability surgery online patient education materials in both English and Spanish are written at higher reading levels than recommended by the American Medical Association and National Institutes of Health, though Spanish online patient education materials were more readable on average.
RESUMEN
BACKGROUND: Clinical quality registries (CQRs) are intended to enhance quality, safety, and cost reduction using real-world data for a self-improving health system. Starting in 2001, Kaiser Permanente established several medical device CQRs as a quality improvement initiative. This report examines the contributions of these CQRs on improvement in health outcomes, changes in clinical practice, and cost-effectiveness over the past 20 years. METHODS: Eight implant registries were instituted with standardized collection from the electronic health record and other institutional data sources of patient characteristics, medical comorbidities, implant attributes, procedure details, surgical techniques, and outcomes (including complications, revisions, reoperations, hospital readmissions, and other utilization measures). A rigorous quality control system is in place to improve and maintain the quality of data. Data from the Implant Registries form the basis for multiple quality improvement and patient safety initiatives to minimize variation in care, promote clinical best practices, facilitate recalls, perform benchmarking, identify patients at risk, and construct reports about individual surgeons. RESULTS: Following the inception of the Implant Registries, there was an observed (1) reduction in opioid utilization following orthopedic procedures, (2) reduction in use of bone morphogenic protein during lumbar fusion allowing for cost savings, (3) reduction in allograft for anterior cruciate ligament reconstruction and subsequent decrease in organizationwide revision rates, (4) cost savings through expansion of same-day discharge programs for joint arthroplasty, (5) increase in the use of cement fixation in the hemiarthroplasty treatment of hip fracture, and (6) organizationwide discontinuation of an endograft device associated with a higher risk for adverse outcomes following endovascular aortic aneurysm repair. CONCLUSION: The use of Implant Registries within our health system, along with clinical leadership and organizational commitment to a learning health system, was associated with improved quality and safety outcomes and reduced costs. The exact mechanisms by which such registries affect health outcomes and costs require further study.

INTRODUCTION: Ambulatory clerkships, including longitudinal integrated clerkships (LICs), face challenges to assessment, including time pressure and clinical demands on preceptors. High-quality clinical assessment is critical to implementing competency-based medical education, generating valid grades, and supporting learning. This importance is further heightened with the new pass/fail scoring for US Medical Licensing Exam Step 1, discontinuation of US Medical Licensing Exam Step 2 Clinical Skills, and the growing concern for bias in assessment. METHODS: The Kaiser Permanente Bernard J. Tyson School of Medicine's LIC spans the first 2 years with 50 students per class. In 2021-2022, the authors created a new faculty role, the clinical assessment specialist (CASp). CASps are highly trained clinical teachers who directly observe clerkship students in the ambulatory setting, provide feedback, and complete competency-based assessment forms. RESULTS: CASps completed 186 assessments of first-year (Y1) LIC students and 333 assessments of second-year (Y2) LIC students. Y2 students achieved average higher milestones and were rated as requiring less supervision compared to Y1 students. Y1 students rated CASps more favorably than Y2 students. Preceptors rated the contribution of CASps similarly across both years. Clerkship directors described benefits including identification of at-risk students and value of augmenting preceptor assessments. DISCUSSION: The CASp role may offer an innovative way to generate valid assessment of student performance, offset clinical pressures faced by preceptors, identify at-risk students, and mitigate bias, especially in an LIC. Future studies may examine assessment validity, including use in summative assessment. CONCLUSION: CASps are an innovative approach to clinical clerkship assessment.

The management of glenoid bone loss in shoulder instability can be challenging. Although shoulder instability can often be managed with arthroscopic soft-tissue procedures alone, the extent of glenoid bone loss and bipolar bone defects may require bone augmentation procedures for restoration of stability. In this setting, patient evaluation, examination, treatment options, and surgical pearls are vital. Furthermore, a treatment algorithm is established to guide both indications and the technical application of procedures including Bankart repair with remplissage, Latarjet procedure, and glenoid bone graft options. The limitations, complications, and current research pertinent to each treatment assist in guiding treatment.

BACKGROUND: Research has identified disparities in returns to care by race/ethnicity following primary total joint arthroplasty. We sought to identify risk factors for 90-day emergency department (ED) returns following primary total knee arthroplasty (TKA) or total hip arthroplasty (THA) for these populations. METHODS: Black, Hispanic, and non-Hispanic White patients who underwent elective primary unilateral TKA and THA in an integrated US healthcare system were identified. Risk factors for 90-day postoperative ED visits including patient demographics, household income and education, comorbidities, preoperative healthcare utilization, and copay data were identified with multivariable logistic regression. RESULTS: Postoperative 90-day ED visits occurred in 13.3% of 79,565 TKA patients (17.2% Black; 14.9% Hispanic; 12.5% White) and 11.0% of THA patients (13.4% Black; 12.1% Hispanic; 10.7% White). Across racial/ethnic categories, patients who had an ED visit within 1 year of their TKA or THA date were more likely to have a 90-day ED return. Shared risk factors for TKA patients were chronic lung disease and outpatient utilization (25th and 75th percentile), while peripheral vascular disease was a shared risk factor for THA patients. Risk factors for multiple races of TKA and THA patients included depression, drug abuse, and psychosis. Prior copay for White (TKA) and Hispanic (TKA and THA) patients was protective, while preoperative primary care was protective for Black THA patients. CONCLUSION: Future strategies to reduce postoperative ED returns should include directed patient outreach for patients who had ED visits and mental health in the year prior to TKA and THA. LEVEL OF EVIDENCE: III.

Ongoing innovation leads to a continuous influx of new technologies related to shoulder arthroplasty. These are made available to surgeons and marketed to both health-care providers and patients with the hope of improving outcomes. We sought to evaluate how preoperative planning technologies for shoulder arthroplasty affect outcomes. Methods: This was a retrospective cohort study conducted using data from an integrated health-care system's shoulder arthroplasty registry. Adult patients who underwent primary elective anatomic or reverse total shoulder arthroplasty (2015 to 2020) were identified. Preoperative planning technologies were identified as (1) a computed tomography (CT) scan and (2) patient-specific instrumentation (PSI). Multivariable Cox regression and logistic regression were used to compare the risk of aseptic revision and 90-day adverse events, respectively, between procedures for which technologies were and were not used. Results: The study sample included 8,117 procedures (in 7,372 patients) with an average follow-up of 2.9 years (maximum, 6 years). No reduction in the risk of aseptic revision was observed for patients having either preoperative CT scans (hazard ratio [HR] = 1.22; 95% confidence interval [CI] = 0.87 to 1.72) or PSI (HR = 1.44; 95% CI = 0.71 to 2.92). Patients having CT scans had a lower likelihood of 90-day emergency department visits (odds ratio [OR] = 0.84; 95% CI = 0.73 to 0.97) but a higher likelihood of 90-day venous thromboembolic events (OR = 1.79; 95% CI = 1.18 to 2.74). Patients with PSI use had a higher likelihood of 90-day deep infection (OR = 7.74; 95% CI = 1.11 to 53.94). Conclusions: We found no reduction in the risk of aseptic revision with the use of these technologies. Patients having CT scans and PSI use had a higher likelihood of venous thromboembolism and deep infection, respectively. Ongoing research with extended follow-up is being conducted to further examine the effects of these technologies on patient outcomes. Level of Evidence: Diagnostic Level III.

RESUMEN
Debt is a common issue among medical residents in the United States. This review attempts 1) to evaluate the level of debt among residents, 2) to assess perceptions toward debt among residents, 3) to determine debt-management options pursued, and 4) to gauge whether levels of debt affect resident career choices. A systematic literature search of articles published between January 2012 and January 2022 in the MEDLINE, EMBASE, and Cochrane databases was performed. The combination of search terms of (financial literacy OR debt) AND (residency OR graduate medical education) were utilized. Primary outcome measures assessed were the levels of debt and perceptions toward the debt. Secondary outcome measures were debt-management options pursued and whether debt affected career choices for residents. Twenty-one studies evaluating a total of 15,585 residents were included in this systematic review. Levels of debt greater than $200,000 were not uncommon across residents and debt burdens are increasing. Greater levels of debt are associated with increased stress and anxiety. Residents reported multiple debt-management options pursued, including loan forbearance, moonlighting, income-based repayment models, military financial support, and loan forgiveness programs. Those with increased levels of debt were less likely to pursue subspecialty training and academic employment positions. The findings conclude that residents carry a substantial amount of debt, and it is a common source of stress and anxiety. Although there are many different avenues that are pursued for debt repayment, levels of debt appear to affect decisions to pursue subspecialty training and to pursue academic positions. Strategies or programs aimed at reducing the debt burden felt by residents could be of great value.

BACKGROUND: Same-day discharge for shoulder arthroplasty (SA) is well-supported in the literature; however, most studies have focused on healthier patients. Indications for same-day discharge SA have expanded to include patients with more comorbidities, but safety of same-day discharge in this population remains unknown. We sought to compare outcomes following same-day discharge vs. inpatient SA in a cohort of patients considered higher risk for adverse events, defined as an American Society of Anesthesiologists (ASA) classification of ≥3. METHODS: Data from Kaiser Permanente's SA registry were utilized to conduct a retrospective cohort study. All patients with an ASA classification of ≥3 who underwent primary elective anatomic or reverse SA in a hospital from 2018 to 2020 were included. The exposure of interest was in-hospital length of stay: same-day discharge vs. ≥1-night hospital inpatient stay. The likelihood of 90-day post-discharge events, including emergency department (ED) visit, readmission, cardiac complication, venous thromboembolism, and mortality, was evaluated using propensity score-weighted logistic regression with noninferiority testing using a margin of 1.10. RESULTS: The cohort included a total of 1814 SA patients, of whom 1005 (55.4%) had same-day discharge. In propensity score-weighted models, same-day discharge was not inferior to an inpatient stay SA regarding 90-day readmission (odds ratio [OR] = 0.64, one-sided 95% upper bound [UB] = 0.89) and overall complications (OR = 0.67, 95% UB = 1.00). We lacked evidence in support of noninferiority for 90-day ED visit (OR = 0.96, 95% UB = 1.18), cardiac event (OR = 0.68, 95% UB = 1.11), or venous thromboembolism (OR = 0.91, 95% UB = 2.15). Infections, revisions for instability, and mortality were too rare to evaluate using regression analysis. CONCLUSIONS: In a cohort of over 1800 patients with an ASA of ≥3, we found same-day discharge SA did not increase the likelihood of ED visits, readmissions, or complications compared with an inpatient stay, and same-day discharge was not inferior to an inpatient stay with regard to readmissions and overall complications. These findings suggest that it is possible to expand indications for same-day discharge SA in the hospital setting.
RESUMEN
Anatomic total shoulder arthroplasty (aTSA) is an accepted treatment for a variety of degenerative conditions of the glenohumeral joint. The manner in which the subscapularis tendon is handled during the approach in aTSA is not universally agreed on. Failure of the repair after aTSA has been shown to be associated with poorer outcomes in some cases. There is no consensus on how to treat failures, as all techniques described in the literature demonstrate shortcomings. The purpose of this review is to evaluate the methods of handling the tendon in aTSA and to review options for treating failure following surgery. [Orthopedics. 2023;46(5):e264-e272.].

Orthopaedic surgery is one of the most competitive and least diverse specialties in medicine. Affiliation of an orthopaedics with an allopathic medical school impacts research opportunities and early exposure to clinical orthopaedics. The purpose of this study is to examine the potential effect allopathic medical school affiliation has on orthopaedic surgery resident demographics and academic characteristics. Methods: All 202 Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopaedics programs were divided into 2 groups: Group 1 consisted of residency programs without an affiliated allopathic medical school, and Group 2 consisted of programs with an affiliated allopathic medical school. Affiliations were determined by cross-referencing the ACGME residency program list with the medical school list published by Association of American Medical Colleges (AAMC). Program and resident characteristics were then compiled using AAMC's Residency Explorer including region, program setting, number of residents, and osteopathic recognition. Resident characteristics included race, gender, experiences (work, volunteer, and research), peer-reviewed publications, and US Medical Licensing Examination Step 1 scores. Results: Of the 202 ACGME-accredited orthopaedics residencies, Group 1 had 61 (30.2%) programs, and Group 2 had 141 (69.8%) programs. Group 2 had larger programs (4.9 vs. 3.2 resident positions/year; p < 0.001) and 1.7 times the number of residency applicants (655.8 vs. 385.5; p < 0.001). Most Group 2 residents were allopathic medical school graduates, 95.5%, compared with 41.6% in Group 1. Group 1 had 57.0% osteopathic medical school graduates, compared with 2.9% in Group 2. There were 6.1% more White residents in Group 1 residencies (p = 0.025), and Group 2 residencies consisted of 3.5% more Black residents in relation to Group 1 (p = 0.03). Academic performance metrics were comparable between the 2 groups (p > 0.05). Conclusion: This study demonstrated that candidates who successfully match into an orthopaedic surgery residency program achieve high academic performance, regardless of whether the program was affiliated with an allopathic medical school. Differences may be influenced by increased representation of minority faculty, greater demand for allopathic residents, or stronger emphasis on promotion of diversity in those residency programs. Availability of Data and Material: Available on reasonable request. Level of Evidence: Level III. See Instructions for Authors for a complete description of levels of evidence.
RESUMEN
BACKGROUND: Reverse total shoulder arthroplasty (RTSA), initially indicated for cuff tear arthropathy, is increasingly used to treat elderly patients with primary glenohumeral osteoarthritis (GHOA) and an intact rotator cuff. This is often done to avoid revision surgery in elderly patients for rotator cuff failure with anatomic total shoulder arthroplasty (TSA) despite traditionally good outcomes of TSA. We sought to determine whether there was a difference in outcomes in patients aged ≥70 years who received RTSA vs. TSA for GHOA. METHODS: A retrospective cohort study was conducted using data from a US integrated health care system's shoulder arthroplasty registry. Patients aged ≥70 years who underwent primary shoulder arthroplasty for GHOA with an intact rotator cuff were included (2012-2021). RTSA was compared with TSA. Multivariable Cox proportional hazard regression was used to evaluate all-cause revision risk during follow-up, whereas multivariable logistic regression was used to evaluate 90-day emergency department (ED) visits and 90-day readmissions. RESULTS: The final study sample comprised 685 RTSA patients and 3106 TSA patients. The mean age was 75.8 years (standard deviation, 4.6 years), and 43.4% of patients were men. After accounting for confounders, we observed no significant difference in all-cause revision risk for RTSA vs. TSA (hazard ratio, 0.79; 95% confidence interval [CI], 0.39-1.58). The most common reason for revision following RTSA was glenoid component loosening (40.0%). Over half of revisions following TSA were for rotator cuff tear (54.0%). No difference based on procedure type was observed in the likelihood of 90-day ED visits (odds ratio, 0.94; 95% CI, 0.71-1.26) and 90-day readmissions (odds ratio, 1.32; 95% CI, 0.83-2.09). CONCLUSION: RTSA and TSA for GHOA with an intact rotator cuff in patients aged ≥70 years had a similar revision risk, as well as a similar likelihood of 90-day ED visits and readmissions. Although revision risk was similar, the most common causes of revision were different, with rotator cuff tears in TSA patients and glenoid component loosening in RTSA patients.

BACKGROUND: There is significant variability both in how proximal humerus fractures (PHFs) are treated and the ensuing patient outcomes. The purpose of this study was to investigate which surgeon- and patient-specific factors contribute to decision-making in the treatment of adult PHFs. We hypothesized that orthopedic sub-specialty training creates inherent bias and plays an important role in management algorithms for PHFs. METHODS: We performed a prospective cohort investigation in 2 groups of surgeons-traumatologists (N = 25) and shoulder & elbow/sports surgeons (SES) (N = 26)-and asked them to provide treatment recommendations for 30 distinct clinical cases with standardized radiographic and clinical data. This is a population-based sample of surgeons who take trauma call and treat PHFs with different sub-specializations and practice settings including academic, hospital-employed, and private. Surgeons characterized based on subspecialty (trauma vs. SES), experience level (>10 vs. ≤10-years), and employment type (hospital- vs. non-hospital-employed). Chi-square analyses, logistic mixed-effects modeling, and relative importance analysis were used to evaluate the data. RESULTS: Of the patient-specific factors, we found that the management of PHFs is largely dependent on initial radiographs obtained. Traumatologists were more likely to offer open reduction internal fixation (ORIF) and less likely to offer arthroplasty: 69% ORIF (traumatologists) vs. 51% ORIF (SES, P < .001), 8% arthroplasty (traumatologists) vs. 17% (SES, P < .001). Traumatologists were less likely to change from operative (either ORIF or arthroplasty) to non-operative management compared to SES surgeons when presented with additional patient demographic data. Surgeon-specific factors contributed to more than one-half of the variability in decision-making of PHF management while patient-specific factors contributed to about one-third of the variability in decision-making. CONCLUSIONS: As physicians strive to advance the treatment for PHFs and optimize patient outcomes, our findings highlight the complex overlap between surgeon-, fracture-, and patient-specific factors in the final decision-making process.

BACKGROUND: We sought to evaluate the risk of aseptic revision in total knee arthroplasty (TKA) patients who have and do not have a history of primary or revision arthroplasty of a different major joint. METHODS: We conducted a matched cohort study using data from Kaiser Permanente's arthroplasty registries. Patients who underwent primary unilateral TKA (index knee) were identified (2009-2018). Two matches based on exposure history were performed: (1) 33,714 TKAs with a history of primary arthroplasty of a different joint (contralateral knee, either hip, and/or either shoulder) were matched to 67,121 TKAs without an arthroplasty history and (2) 597 TKAs with a history of aseptic revision in a different joint were matched to 1,190 TKAs with a history of a prior arthroplasty in a different joint, but without any revision. After the matches were performed, Cox regressions were used to evaluate aseptic revision risk of the index knee using the no history groups as the reference in regression models. RESULTS: No difference in aseptic revision risk for the index knee was observed when comparing patients who had a prior primary arthroplasty in a different joint to those who did not have an arthroplasty history (hazard ratio = 0.95, 95% CI = 0.86-1.06). Those patients who did not have any prior aseptic revision history in a different joint had higher risk of aseptic revision in the index knee (hazard ratio = 2.06, 95% CI = 1.17-3.63). CONCLUSION: Patients who had a prior revision history had over a 2-fold higher risk of aseptic revision in the index knee, warranting close surveillance of these patients.

Background: The purpose of this study is to compare the incidence of complications associated with tension band wiring (TBW) versus plate osteosynthesis (POS) in the treatment of olecranon fractures. Methods: We performed a retrospective cohort study of operatively treated adult olecranon fractures from an integrated healthcare system by multiple surgeons from January 2008 to December 2011. Patients were divided into two cohorts: fractures fixed using the tension band technique and fractures fixed using plate osteosynthesis. The study was limited to the Orthopedic Trauma Association classification of olecranon fracture type 21-B1, with subtypes 1-3. Outcome measures were loss of fracture fixation requiring revision, postoperative infection, stiffness requiring surgery, and symptomatic hardware removal (HWR). Univariate and multivariable logistic regressions were performed to test the associations between the type of internal fixation and outcomes. Results: A total of 321 olecranon fractures were included (median age: 61 years old, 57 % female); 153 participants were treated with TBW, and 168 patients with POS. There was one failure in the TBW group and two in the POS group (P=0.62). There were no significant differences in the infection rates (TBW 5%, POS 9%, P=0.20) and no reoperations for stiffness. The HWR occurred significantly more often in TBW (29%) than in POS (14%) (OR=0.39, P=0.001). The association between POS and decreased HWR remained highly significant (OR=0.40, P=0.003) after adjusting for clinical variables. Conclusion: In this large study comparing POS and TBW for 21-B1 olecranon fractures, no difference in fixation failure, infection, or postoperative stiffness was noted. A significantly greater risk of symptomatic hardware occurred in TBW. These findings may assist surgeons and patients in considering the risks and benefits of TBW and POS as treatment options for displaced olecranon fractures.
RESUMEN
INTRODUCTION: Centers of excellence and bundled payment models have driven perioperative optimization and surgical site infection (SSI) prevention with decolonization protocols and antibiotic prophylaxis strategies. We sought to evaluate time trends in the incidence of deep SSI and its causative organisms after six orthopaedic procedures in a US-based integrated healthcare system. METHODS: We conducted a population-level time-trend study using data from Kaiser Permanente's orthopaedic registries. All patients who underwent primary anterior cruciate ligament reconstruction (ACLR), total knee arthroplasty (TKA), elective total hip arthroplasty (THA), hip fracture repair, shoulder arthroplasty, and spine surgery were identified (2009 to 2020). The annual incidence of 90-day deep SSI was identified according to the National Healthcare Safety Network/Centers for Disease Control and Prevention guidelines with manual chart validation for identified infections. Poisson regression was used to evaluate annual trends in SSI incidence with surgical year as the exposure of interest. Annual trends in overall incidence and organism-specific incidence were considered. RESULTS: The final study sample was composed of 465,797 primary orthopaedic procedures. Over the 12-year study period, a decreasing trend in deep SSI was observed for ACLR and hip fracture repair. Although there was variation in incidence rates for specific operative years for TKA, elective THA, shoulder arthroplasty, and spine surgery, no consistent decreasing trends over time were found. Decreasing rates of Staphylococcus aureus infections over time after hip fracture repair, shoulder arthroplasty, and spine surgery and decreasing trends in antibiotic resistance after elective THA and spine surgery were also observed. Increasing trends of polymicrobial infections were observed after TKA and Cutibacterium acnes after elective THA. CONCLUSIONS: The overall incidence of deep SSI after six orthopaedic procedures was rare. Decreasing SSI rates were observed for ACLR and hip fracture repair within our US-based healthcare system. Polymicrobial infections after TKA and Cutibacterium acnes after elective THA warrant closer surveillance. LEVEL OF EVIDENCE: IV.
