Outcomes of Concomitant Hip Arthroscopic Surgery for Intra-articular Abnormalities and Endoscopic Abductor Tendon Repair at a Minimum 2-Year Follow-up: A Systematic Review.

Background: Hip labral and chondral lesions are commonly found as co-occurring conditions in patients with abductor tendon tears. Concomitant hip arthroscopic surgery for the correction of intra-articular abnormalities and endoscopic abductor tendon repair has therefore emerged as a strategy to address these conditions simultaneously. Purpose: To systematically review the existing literature assessing clinical outcomes after endoscopic abductor tendon repair with concomitant hip arthroscopic surgery for the treatment of intra-articular abnormalities. Study Design: Systematic review; Level of evidence, 4. Methods: Under PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, the PubMed, CENTRAL, and Scopus databases were queried in May 2023 to conduct this systematic review using the keywords "hip arthroscopy,""gluteal,""abductor,""gluteus,""minimus," and "medius." Articles were included if they reported preoperative and postoperative patient-reported outcome measure (PROM) scores for patients undergoing endoscopic abductor tendon repair for gluteus medius and/or gluteus minimus tears with concomitant hip arthroscopic surgery for the treatment of labral tears and/or femoroacetabular impingement. We identified a total of 404 articles after our initial search. Title, author, publication date, study design, patient characteristics, preoperative radiographic findings (lateral center-edge angle, alpha angle, and Tönnis grade), concomitant surgical procedures performed, preoperative and postoperative PROM scores, measures of clinical benefit, and secondary surgery performed (revision arthroscopic surgery, revision abductor tendon repair, and conversion to total hip arthroplasty) were recorded. Results: After duplicate articles were removed, 270 articles entered the abstract screening phase, and 11 full-text articles were reviewed. Overall, 5 articles were included in the systematic review. A total of 223 hips were included, with mean follow-up times ranging from 26 to 74 months. All studies reported a significant improvement ( Conclusion: Our systematic review demonstrated that patients who underwent concomitant endoscopic abductor tendon repair and hip arthroscopic surgery had significant improvements on PROMs with low rates of secondary surgery at a minimum 2-year follow-up. Longer-term studies are needed for us to understand concomitant treatment methods for multiple abnormalities in patients undergoing hip arthroscopic surgery in the future.
