Association Between Proximal Hamstring Tear Characteristics and Achievement of Clinically Significant Outcomes After Endoscopic and Open Repair at Minimum 2-Year Follow-up.

Surgical repair of proximal hamstring tendon tears with varying extents of tendon retraction resulted in high rates of achieving PASS at the 2-year follow-up. Among complete tears with <2 cm of retraction, endoscopic repairs exhibited equal or higher rates of achieving PASS compared with open repairs across multiple PROs at 2 years postoperatively. However, patients with complete tears and retraction >2 cm achieved lower rates of PASS on the HOS-ADL and HOS-SS scales and had a higher rate of complications.
