Abstract
Purpose
Gluteus medius (GM) tears are a common cause of peritrochanteris pain among middle and older populations. This condition is associated with lateral hip pain and significant disability while ambulating or during weightbearing activities. This study aims to evaluate outcomes of endoscopic isolate GM repairs at minimum 5-year follow-up.
Methods
Prospectively collected data was retrospectively analyzed for all patients who underwent endoscopic GM repairs between May 2009 and December 2018. Included patients had completed pre-operative and minimum of 5-year patient reported outcomes (PRO) for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), Visual Analogue Scale (VAS) and patient satisfaction. The MCID was calculated for all PROs and included in the analysis. Complications and secondary surgery including subsequent Total Hip Replacement were assessed. A failure analysis based on the grade of GM tear was performed.
Results
A total of 26 patients were included in the study. Significant improvement was seen in all PROs and high patient satisfaction was reported. Furthermore, a high percentage of patients reached the calculated MCID for mHHS, NAHS, and iHOT 12. In the cohort, 3 (11.54%) hips underwent revision arthroscopy and 6 (23.08%) converted to arthroplasty. Of these, 100% and 83.34%, respectively, had a higher-grade GM tear, defined as >50% at primary endoscopic GM repairs.
Conclusion
Endoscopic gluteus medius repairs yield significant improvement in mHHS, NAHS, HOS-SSS, iHOT-12, and VAS at 5-year minimum follow-up. Patients with a higher grade of GM tear had increased revision surgery rates and conversion to THA.
