Minimally Invasive Repair of Proximal Hamstring Avulsions: Outcomes of Early Intervention with a Double-Row Knotless Suture Anchor Technique

Introduction: Hamstring muscle injuries are among the most common muscle injuries. With about 12% involve avulsion of the proximal origin from the ischial tuberosity. Case Series: We present the outcome of four patients with acute, complete proximal hamstring tendon avulsions treated with a minimally invasive open repair using a double-row knotless suture anchor construct. The surgical technique, post-operative rehabilitation protocol, and clinical outcomes at 4–6-month follow-up are described. All patients achieved complete functional recovery and returned to their pre-injury activity levels without complications or tendon re-rupture. Conclusion: These results demonstrate the clinical effectiveness of timely surgical repair using a knotless double-row technique for proximal hamstring avulsions.
