Full-Thickness Gluteus Medius Tears With or Without Concomitant Hip Arthroscopy: Minimum 2-Year Outcomes Using an Open Approach and Contemporary Tendon Repair Techniques

Abstract

Background: Gluteus medius (GM) tears are a well-established source of pain and disability. An open approach has been recognized with complete full-thickness and large GM tears, yet the current literature provides few reports on outcomes for this specific situation. Purpose: To report and analyze minimum 2-year patient-reported outcomes (PROs) from patients who underwent open GM repair in the setting of a full-thickness tear with or without concomitant hip arthroscopy through use of contemporary tendon repair techniques. Study Design: Case series; Level of evidence, 4. Methods: Prospectively collected data were retrospectively reviewed for patients who underwent hip preservation surgery and total hip arthroplasty (THA) between April 2008 and May 2017. Patients were included in this study if they underwent open repair of GM full-thickness tears. The exclusion criteria were incomplete follow-up, workers’ compensation status, repair regarding size and pattern of the GM, open repair of partial GM tear, open repair with allograft or autograft augmentation, and/or additional gluteus maximus transfer. Pre- and postoperative PROs for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sport-Specific Subscale (HOS-SSS), and visual analog scale (VAS) score for pain and satisfaction were recorded. Statistical significance was set at P
