INTRODUCTION: Overlapping surgery (OS) refers to when an attending surgeon supervises two surgeries at the same time with noncritical portions of both surgeries occurring simultaneously. Limited literature reviewing OS exists in orthopaedics. Our goal is to provide insight into this practice across orthopaedic subspecialities to inform its future utilization. METHODS: A review of the literature was conducted after Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review guidelines...

INTRODUCTION: The COVID-19 pandemic negatively affected surgical training in the United States. We hypothesized that reported case volume during pediatric orthopaedic surgery fellowship training would decrease markedly during the 2019 to 2020 academic year, which corresponded with the COVID-19 outbreak. METHODS: The Accreditation Council for Graduate Medical Education provided nationwide case logs for accredited pediatric orthopaedic surgery fellows (2017 to 2021)...

INTRODUCTION: Orthopaedic studies published in high-impact medical journals are often believed to have a high prevalence of negative or neutral results and possess methodological characteristics that may bias toward nonsurgical treatments. The purpose of this study was to compare study characteristics, methodologic quality, exposure, and outcome direction among orthopaedic randomized control trials (RCTs) published in high-impact medical and orthopaedic journals and to identify study attributes associated with greater impact...

The American Academy of Orthopaedic Surgeons (AAOS) has developed appropriate use criteria (AUC) for humeral component design during primary anatomic total shoulder arthroplasty. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to determine the appropriateness of various humeral component designs during primary anatomic total shoulder arthroplasty. The AUC for humeral component design during primary anatomic total shoulder arthroplasty were derived by identifying clinical indications evident during the clinical decision-making process...

INTRODUCTION: To improve transparency between candidates and training programs, a preference signaling program (PSP) was implemented before the 2022 to 2023 orthopaedic surgery match. The PSP allows applicants to 'signal' up to 30 programs, informing the program of the applicant's particular interest in interviewing for their available position(s). This study reports the perspectives of orthopaedic surgery residency applicants and program directors (PDs) on the effects of preference signaling on the orthopaedic match...

Arthroscopy is an orthopaedic technique that provides surgical solutions in a minimally invasive fashion. Since its introduction, arthroscopy has become a preferred surgical approach for treating various orthopaedic pathologies, such as meniscal tears, anterior cruciate ligament ruptures, rotator cuff tears, and wrist, elbow, ankle, and hip conditions. Despite its ubiquity, surgical training in arthroscopy poses several challenges for educators and trainees. Arthroscopy involves neuromotor skills which differ from those of open surgery, such as the principles of triangulation, bimanual dexterity, and the ability to navigate a three-dimensional space on a two-dimensional screen...

INTRODUCTION: Studies on diversity in orthopaedic surgery have exclusively examined challenges from a race or sex perspective. This study examines trends in the diversity of entering orthopaedic surgery residents from the intersection of race and sex. METHODS: The American Association of Medical Colleges was queried for individuals entering orthopaedic surgery residencies in the United States from 2001 to 2020. Deidentified data on self-reported sex and race were collected...

INTRODUCTION: Postoperative urinary retention (POUR) after lumbar fusion surgery can lead to longer hospital stays and thus increased risk of developing other postoperative complications. Therefore, we aimed to determine the relationship between POUR and (1) surgical approach and (2) anesthetic agents, including sugammadex and glycopyrrolate. METHODS: After institutional review board approval, L4-S1 single-level lumbar fusion surgeries between 2018 and 2021 were identified...

INTRODUCTION: The use of antibiotic-laden bone cement (ALBC) for infection prophylaxis in the setting of primary total knee arthroplasty (TKA) remains controversial. Using data from the American Joint Replacement Registry (AJRR), (1) we examined the demographics of ALBC usage in the United States and (2) identified the effect of prophylactic commercially available ALBC on early revision and readmission for prosthetic joint infection (PJI) after primary TKA. METHODS: This is a retrospective cohort study of the AJRR from 2017 to 2020...

OBJECTIVES: The purpose of this study was to determine the stability of statistical findings among sham surgery randomized controlled trials (RCTs) in orthopaedic surgery using fragility analysis. METHODS: PubMed systematic review was conducted to include studies reporting dichotomous outcomes pertaining to sham surgery. The final review included eight RCTs involving only partial meniscectomies and vertebroplasties from 2009 to 2020. With a fixed sample size with dichotomous outcome measures (events versus non-events), the Total Fragility Index (TFI), which is composed of the fragility index (FI) and reverse fragility index (RFI), was calculated by altering the ratio of events to non-events in an iterative fashion until results were reversed from significant to nonsignificant findings (FI) or vice versa (RFI)...

INTRODUCTION: Matching into orthopaedic residency has become difficult, and the US Medical Licensing Examination Step 1 transition to pass/fail scoring has complicated the process. Advisors' ability to mentor students has decreased, and program directors may rely on Step 2 Clinical Knowledge (CK) scores in selecting which candidates to interview. This study aims to offer a method to predict Step 2 CK outcomes based on preadmission and preclinical performance. METHODS: The study investigated 486 students from a US medical school who enrolled in 2017 and 2018...

BACKGROUND: In a previous study, we documented patient implicit bias that surgeons are men. As a next step, we tested the implicit bias of surgeons that women in medicine have leading (chair, surgeon) or supporting roles (medical assistant, physician assistant). QUESTIONS/PURPOSE: (1) What is the relationship between the implicit associations and expressed beliefs of surgeons regarding women as leaders in medicine? (2) Are there factors associated with surgeon implicit association and explicit preference regarding the roles of women in medicine? METHODS: A total of 102 musculoskeletal surgeon members of the Science of Variation Group (88 men and 12 women) completed an implicit association test (IAT) of implicit bias regarding sex and lead/support roles in medicine and a questionnaire that addressed respondent demographics and explicit preference regarding women's roles...

INTRODUCTION: Artificial intelligence (AI) programs have the ability to answer complex queries including medical profession examination questions. The purpose of this study was to compare the performance of orthopaedic residents (ortho residents) against Chat Generative Pretrained Transformer (ChatGPT)-3.5 and GPT-4 on orthopaedic assessment examinations. A secondary objective was to perform a subgroup analysis comparing the performance of each group on questions that included image interpretation versus text-only questions...

BACKGROUND: An inverse relationship coined the "obesity paradox" has been propositioned, in which body mass index (BMI) may be contradictorily protective in patients undergoing surgery or treatment of chronic disease. This study sought to investigate the BMI associated with the lowest rate of medical complications after total shoulder arthroplasty (TSA). METHODS: The American College of Surgeons National Surgical Quality Improvement Project database was queried to identify adults who underwent elective primary TSA between January 2012 and December 2020...

Hip abductor tears have recently gained recognition as a more prevalent injury than previously thought. This article will detail the pathophysiology of injury, physical symptoms commonly found at presentation, diagnostic imaging to best diagnose tears and when they should be ordered, and how to properly classify the injury and finally summarize the treatment options available with expert opinions about which are most successful.

Discrete choice experiments are a robust technique for quantifying preferences. With this method, respondents are presented with a series of hypothetical comparisons described by attributes with varying levels. The aggregated choices from respondents can be used to infer the relative importance of the described attributes and acceptable trade-offs between attributes. The data generated from discrete choice experiments can aid surgeons in aligning patient values with treatment decisions and support the design of research that is responsive to patient preferences...

Nonarthroplasty knee procedures are common and may cause a wide spectrum of postoperative pain, ranging from minimal to severe, depending on the patient, pathology, and procedure. Procedures include ligament repair and reconstruction, especially anterior cruciate ligament reconstruction, meniscal débridement, repair and transplant, periarticular osteotomy, and cartilage restoration. Multimodal analgesia regimens have been implemented successfully, but notable variation characterizes current protocols. Increased public and physician awareness of the burden of opioid usage in the United States has encouraged the medical community to embrace opioid-minimizing and nonopioid techniques to mitigate the deleterious effects of these medications...

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...
