Demographic trends of boxing-associated fractures over 10 years.

Background: Boxing is a sport well-known for the risk of injury. However, the epidemiology of boxing-associated fractures has not been well studied. This study aims to report the characteristics of boxing fractures that lead to presentation to the emergency room and evaluate the demographics and practices of the patients to prevent these injuries.

Low-Volume and Early-Career Surgeons Have Higher Risk for Reoperation and Complications Following Anterior Cruciate Ligament Reconstruction.

Purpose: To characterize the population of surgeons performing anterior cruciate ligament reconstructions (ACLRs) in the United States and investigate the relationships between surgeon volume, career duration, and practice setting on surgical outcomes.

Methods: A large nationwide insurance database was queried for patients undergoing primary ACLR. Provider gender, degree type (allopathic vs osteopathic), practice setting (academic vs private as defined by ACGME affiliation), surgeon volume per year, and career duration were obtained.

Impact of surgeon volume, experience, and training on outcomes after arthroscopic rotator cuff repair: a nationwide analysis of 1489 surgeons.

Background: Given the complexity of arthroscopic rotator cuff repair (ARCR) and increasing prevalence, there is a need for comprehensive, large-scale studies that investigate potential correlations between surgeon-specific factors and postoperative outcomes after ARCR. This study examines how surgeon-specific factors including case volume, career length, fellowship training, practice setting, and regional practice impact two-year reoperation rates, conversion to total shoulder arthroplasty (anatomic or reverse), and 90-day post-ARCR hospitalization.

Methods: The PearlDiver Mariner database was used to collect surgeon-specific variables and query patients who underwent ARCR from 2015 to 2018.

Socioeconomic Factors Including Patient Income, Education Level, and Health Insurance Influence Postoperative Secondary Surgery and Hospitalization Rates Following Hip Arthroscopy.

Purpose: To evaluate a large cross-sectional sample of patients utilizing administrative database records and analyze the effects of income, insurance type, and education level on outcomes after hip arthroscopy, including 2-year revision surgery, conversion to total hip arthroplasty (THA), and 90-day hospitalizations.

Methods: Current Procedural Terminology codes were used to query the PearlDiver Mariner database from October 2015 to January 2020 for patients undergoing hip arthroscopy with a minimum 2-year follow-up. Patients were categorized by mean family income in their zip code of residence (MFIR), health insurance type, and educational attainment in their zip code of residence (EAR).

Multiparametric MRI of Knees in Collegiate Basketball Players: Associations With Morphological Abnormalities and Functional Deficits.

Background: Rates of cartilage degeneration in asymptomatic elite basketball players are significantly higher compared with the general population due to excessive loads on the knee. Compositional quantitative magnetic resonance imaging (qMRI) techniques can identify local biochemical changes of macromolecules observed in cartilage degeneration.

Purpose/hypothesis: The purpose of this study was to utilize multiparametric qMRI to (1) quantify how T and T relaxation times differ based on the presence of anatomic abnormalities and (2) correlate T and T with self-reported functional deficits.
