Outcomes of Endoscopic Gluteus Medius Repair with Minimum 2-Year Follow-up

Abstract

ObjectivesGluteus medius (GM) tears may be present in as many as 25% of late middle-aged women, 10% of middle-aged men, and are often misdiagnosed. Outcomes of endoscopic repair of gluteus medius tears have seldom 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.MethodsBetween April 2009 and January 2010, data was prospectively collected for all patients undergoing endoscopic gluteus medius repair. Inclusion criteria for the study were patients undergoing endoscopic gluteus medius repair for either high-grade partial or full thickness tears. Only patients with endoscopic evidence of gluteus medius tear were treated surgically. In the case of articular side GM tear, a trans-tendinous repair technique was used, whereas in the presence of full thickness tear the tendon was refixated to the bone directly.ResultsA total of 15 hips met the inclusion criteria. Our cohort included 14 females and one male, with an average age of 58 years old (range, 44 to 74 years). Endoscopically, six cases were found to be partial-thickness tears. Nine were either full-thickness tears or near full-thickness tears which were completed for the repair. Follow-up was obtained on all patients at an average of 27 months post-operatively (range, 24 to 33). Fourteen of the 15 patients showed post-operative improvement in all four hip specific scores, with an average improvement of more than 30 points for all scores. Satisfaction with the surgery results was reported to be “good” to “excellent” (Seven to 10 out of 10) in 13 of 15 patients.ConclusionsThis study demonstrates that endoscopic surgical repair, whether performed through a trans-tendinous or full-thickness technique, can be an effective treatment of GM tears at a minimum follow-up of two years. Longer-term follow-up studies are necessary to determine whether these therapeutic and functional gains are maintained.
