The indication for surgery was refractory chronic PHT symptoms for &gt;6 months. The primary outcome measure was the Parisian Hamstring Avulsion Score (PHAS). Secondary outcomes included the Tegner Activity Scale score, University of California\u2013Los Angeles (UCLA) Activity Scale score, return to sport, postoperative patient satisfaction, and the rate of complications. In this study, the terms \u201cpartial involvement\u201d or \u201ccomplete involvement\u201d refer to the extent of magnetic resonance imaging signal changes across the tendon, rather than to true tendon ruptures or avulsions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The study included 42 patients with a mean age of 50.4 years (SD, 10.4 years).

At the last follow-up, 30 of 39 patients (76.9%) returned to sport, with 18 of 39 (46.2%) achieving their preinjury sport level or higher. The median time to return to sport was 5.2 months (IQR, 3.7-6.3 months). Patient satisfaction was high, with 82.1% reporting satisfaction with the operated leg.
