COVID-19 Resulted in Reduction Trainee Bedside Experience, But No Reduction in Surgical Experience.

Purpose: Because of the concerns regarding residency process during the pandemic, this study aimed to investigate the volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room.

Methods: This retrospective chart study evaluated variables such as volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room, from an orthopaedic department in a tertiary trauma center throughout the COVID-19 pandemic era. Comparing these measures was an indirect evaluation tool for measuring the amount of work completed and clinical exposure gained by the residents.

Trends in Female Authorship in Orthopaedic Literature from 2002 to 2021: An Analysis of 168,451 Authors.

Acute Case of Trichobezoar Diagnosed From Computed Tomography and 3D Images: Rapunzel Syndrome Re-examined.

A trichobezoar is a rare cause of abdominal pain due to an indigestible mass in the gastrointestinal tract that is composed of a patient's hair. If a trichobezoar grows and extends from the gastric body to the pylorus and into the small bowel, it is considered Rapunzel syndrome. We present a case of an 11-year-old female patient with Rapunzel syndrome who presented with four weeks of colicky abdominal pain, vomiting, constipation, and severe malnutrition.

Risk Factors for a Failed Transmetatarsal Amputation in Patients with Diabetes.

Background: Transmetatarsal amputation (TMA) is a well-recognized limb-salvage procedure, often indicated for the treatment of diabetic foot infections. Currently, there is no widespread agreement in the literature with regard to the factors associated with failure of TMA. This study aimed to define risk factors for the failure of TMA, defined as below-the-knee or above-the-knee amputation, in patients with diabetes.

Maximal Outcome Improvement Willingness Thresholds Are Predictive of a Patient's Willingness to Undergo the Same Surgery, in Retrospect, Given the Known Outcome of Their Primary Hip Arthroscopy.

Purpose: To determine the percent maximal outcome improvement willingness thresholds (MOWTs) for the Nonarthritic Hip Score (NAHS) and the visual analog scale (VAS) for pain that were associated with a patient's willingness to undergo surgery, in retrospect, given the known outcome of their primary hip arthroscopy with concomitant endoscopy for gluteus medius (GM) tear repair.

Methods: An anchor question was provided to patients who underwent primary hip arthroscopy for femoroacetabular impingement syndrome with concomitant endoscopic GM tear repair between April 2008 to April 2020. Patients were included if they answered the anchor question and had baseline and postoperative minimum 1-year follow-up scores for the NAHS and VAS.

Methods: Between January 2012 and August 2017, 71 SS patients were matched for age, sex, body mass index, and follow-up to 71 DS patients.

Nonarthritic Hip Pathology Patterns According to Sex, Femoroacetabular Impingement Morphology, and Generalized Ligamentous Laxity.

Background: Sex differences are frequently encountered when diagnosing orthopaedic problems. Current literature suggests specific sex differences, such as a higher prevalence of cam-type femoroacetabular impingement syndrome in male patients and features of hip instability in female patients.

Purpose: To identify hip pathology patterns according to sex, alpha angle deformity, and generalized ligamentous laxity (GLL) in a nonarthritic patient population that underwent primary hip arthroscopy in the setting of femoroacetabular impingement syndrome and labral tears.

Modern Suture Anchor Techniques for Gluteus Medius Tear Repair With Concomitant Total Hip Arthroplasty Using the Direct Anterior and Posterior Approaches.

Gluteus medius (GM) tears are currently a well-established source of pain and disability. However, their role in primary total hip arthroplasty (THA) in the setting of osteoarthritis (OA) has been underexamined in the literature. The purpose of this study was to report on short-term patient-reported outcome measurements (PROMs) for patients who underwent concomitant primary THA and GM repair.

Best Practice Guidelines for Propensity Score Methods in Medical Research: Consideration on Theory, Implementation, and Reporting. A Review.

Rigorous and reproducible methodology of controlling for bias is essential for high-quality, evidence-based studies. Propensity score matching (PSM) is a valuable way to control for bias and achieve pseudo-randomization in retrospective observation studies. The purpose of this review is to 1) provide a clear conceptual framework for PSM, 2) recommend how to best report its use in studies, and 3) offer some practical examples of implementation.

Cost-Effectiveness of Hip Arthroscopy for Treatment of Femoroacetabular Impingement Syndrome and Labral Tears: A Systematic Review.

Background: Hip arthroscopy has frequently been shown to produce successful outcomes as a treatment for femoroacetabular impingement (FAI) and labral tears. However, there is less literature on whether the favorable results of hip arthroscopy can justify the costs, especially when compared with a nonoperative treatment.

Purpose: To systematically review the cost-effectiveness of hip arthroscopy for treating FAI and labral tears.
