Background:
Partial-thickness undersurface tears of the gluteus medius tendon are a known source of lateral hip pain and functional impairment.
Methods:
This case series included 25 patients treated via endoscopic transtendinous repair, with minimum 2-year follow-up evaluating PROs, VAS pain scores, strength, and gait analysis.
Key Findings:
- Significant improvement across all outcome measures.
- Restoration of strength and normalization of gait in many patients.
- No complications or revision surgeries reported.
Conclusions:
Endoscopic repair of partial-thickness abductor tears is a safe, effective intervention offering durable symptom relief and functional gains.
What Does This Mean for Providers?
Providers can consider endoscopic transtendinous repair as a reliable treatment for partial undersurface gluteus medius tears, with favorable medium-term outcomes and minimal risk of complications.
