Summary
Endoscopic proximal hamstring repair (ePHR) effectively improves pain and function. This study shows significant gains in strength, activity, and range of motion post-surgery for hamstring tears.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Musculoskeletal Research
Background:
- Proximal hamstring tears can cause significant pain and functional limitations.
- Surgical repair aims to restore function and alleviate pain.
- Endoscopic techniques offer a minimally invasive approach to hamstring repair.
Purpose of the Study:
- To evaluate functional and subjective outcomes of endoscopic proximal hamstring repair (ePHR).
- To assess treatment effectiveness by comparing pre- and post-operative metrics.
- To analyze complications, and outcomes based on tear chronicity and completeness.
Main Methods:
- Retrospective case series of 20 patients undergoing ePHR (Nov 2014 - Jan 2019).
- Minimum 1-year follow-up analyzing passive range of motion (PROM), strength, pain (VAS), activity (UCLA), and hip function (mHHS).
- Complications and return-to-activity rates were recorded.
Main Results:
- Significant improvements observed in hamstring strength, hip flexion PROM (+17.3°), UCLA activity (+3), and VAS pain (-3 points).
- High return-to-work (100%) and sport (95%) rates achieved.
- Complete tears showed higher modified Harris Hip Scores (mHHS) postoperatively compared to partial tears.
Conclusions:
- Endoscopic proximal hamstring repair is an effective surgical option.
- ePHR leads to significant improvements in patient pain and functional outcomes.
- The procedure demonstrates good outcomes for both acute and chronic proximal hamstring tears.
