Summary: This study reports good to excellent satisfaction and clinical results of 11 endoscopic repairs of partial and full thickness tears of the gluteus medius with an average follow-up of 7 months.


Gluteus medius tears may be present in as many as 25% of late middle-aged women, 10% of middle-aged men, and can either be partial or full thickness tears. Outcomes of endoscopic repair of gluteus medius tears have scarcely been reported. The purpose of this study was to report the early outcomes of endoscopic repair of partial and full thickness tears of the gluteus medius.


Between February 2009 and April 2011, data was prospectively collected for all patients undergoing endoscopic gluteus medius repairs. Only patients with evidence of gluteus medius tear on magnetic resonance, lateral hip pain and weakness of the gluteus medius were treated surgically. Patients were assessed pre- and post-operatively using four hip specific questionnaires (the modified Harris Hip Score, the Non-Arthritic Hip Score, the two Hip Outcome Score subscales: the Sport Specific and the Activities of Daily Living).Post-operatively, patients were asked for their satisfaction from the surgery on a scale from 0 to 10. Patients who did not complete the pre- and post-operative hip questionnaires were excluded from the study.


Of the 17 patients who underwent endoscopic repair of a torn gluteus medius during our study, 11 met the inclusion/eclusion criteria. Our cohort included 10 females and 1 male, with an average age of 58 years old (range, 44 to 74 years). Endoscopically, 2 cases were found to be partial-thickness tears, 3 were high-grade partial-thickness tears, and 6 were full-thickness tears. At an average follow-up of 7 months, 10 of the 11 patients showed post-operative improvement in all four hip specific scores, with an average improvement of more than 22.5 points for all scores. Satisfaction with the surgery results was reported to be ‘good’ to ‘excellent’ (7 to 10 out of 10) in 8 of 11 patients.


This study suggests that endoscopic surgical repair can be an effective treatment of gluteus medius tears in the short term. A longer-term follow up study would help in finding out if this approach is effective long-term.
