Evaluation of Outcomes Following Arthroscopic Treatment of Femoroacetabular Impingement Syndrome Across Different Surgeons, Surgical Techniques, and Postoperative Protocols: A Multi-institutional Study

Abstract

Background: Femoroacetabular impingement syndrome (FAIS) is frequently treated arthroscopically with osteoplasty and labral repair. Surgical preferences vary in terms of equipment, technique, and postoperative protocol. Patient-reported outcome measures (PROMs) are valuable tools to assess outcomes across different institutions. Purpose: To compare PROMs after FAIS arthroscopy and evaluate the impact on postoperative outcomes with independent surgeons utilizing different surgical techniques and postoperative protocols. Study Design: Cohort study; Level of evidence, 2. Methods: Prospective data were collected from patients with a 2-year follow-up after arthroscopic FAIS treatment by 2 orthopaedic surgeons from different states, each attending different sports medicine fellowships. Patients were matched according to age, sex, and body mass index. Data included patient characteristics, surgical findings, and the Hip disability and Osteoarthritis Outcome Score (HOOS) preoperatively and 2 years postoperatively. Patients with revision surgery, concomitant procedures, or incomplete pre- and postoperative data were excluded. Surgeon A utilized interportal capsulotomy, capsular repair, all-suture anchors, and a postoperative hip brace. Surgeon B employed periportal capsulotomy without repair, polyether ether ketone suture anchors, and no brace. The 2 high-volume arthroscopists (>100 hips/year) performed osteoplasty and labral repair and used a large perineal post. Cohorts were analyzed with appropriate t tests, with significance set at P
