Females Have Higher Return-to-Sport Rate Than Males Among Collegiate Athletes After Hip Arthroscopy for Femoroacetabular Impingement Due to the Difference in the Type of Sports, Type of Impingement, and Prevalence of Severe Cartilage Damage.

Purpose: To investigate the return to sport (RTS) rate and the sex-based difference of collegiate athletes after arthroscopic treatment for femoroacetabular impingement (FAI).

Methods: Patients who were collegiate athletes at the time of surgery and underwent hip arthroscopy for treatment of FAI between January 2009 and June 2020 were included. Patients were excluded if they were in their final year of eligibility, graduated, retired, or had plans to retire from collegiate play before surgery.

Evaluating the Morphology of Unique Superficial Fissured Cartilage Lesions at the Femoral Head-Neck Junction in Patients with Femoroacetabular Impingement Syndrome.

Background: While an association between femoroacetabular impingement (FAI) and osteoarthritis (OA) has been reported, the mechanistic differences and transition between the 2 conditions is not fully understood. In FAI, cartilage lesions at the femoral head-neck junction can sometimes be visualized during hip arthroscopy.

Purpose/hypothesis: The purpose of this study was to describe a unique dimpled pattern of superficial fissured cartilage lesions on the femoral head-neck junction at impingement site in patients with FAI syndrome (FAIS) and to evaluate the clinical, histological, and genetic phenotype of this cartilage.
