Purpose
To describe the anatomy, pathology, and surgical options for gluteus medius tendon tears and to present a novel trans-tendinous endoscopic technique for repairing partial-thickness undersurface tears.
Methods
The authors reviewed existing literature on trochanteric pain and gluteus medius pathology, and analyzed current open and endoscopic repair strategies. They identified a gap in techniques to address undersurface tears and developed a new endoscopic approach.
Key Findings
- Partial-thickness undersurface tears of the gluteus medius are commonly misdiagnosed as trochanteric bursitis.
- These tears resemble rotator cuff injuries in the shoulder, but pose unique arthroscopic challenges.
- Traditional techniques provide limited access to the deep surface of the tendon.
- The trans-tendinous endoscopic method improves visualization and enables precise repair of these lesions.
Conclusion
Endoscopic trans-tendinous repair is a promising technique for treating partial-thickness gluteus medius tears that are otherwise difficult to access and treat arthroscopically.
What This Means for Patients
Patients with persistent outer hip pain misdiagnosed as bursitis may actually have gluteus medius tendon tears. This novel surgical technique offers a minimally invasive solution that may improve recovery and hip function.
