Patients were included only if they had a chronic proximal hamstring tear (defined as \u22654 weeks from symptom onset to surgery). Patients were excluded if they had a tear treated &lt;4 weeks after injury, underwent hamstring reconstruction, or claimed workers\u2019 compensation. Patients who reported minimum 2-year follow-up for VAS, patient satisfaction, and the following PROs had their outcomes analyzed: the modified Hip Harris Score, Non-arthritic Hip Score, iHOT-12 (International Hip Outcome Tool), and Hip Outcome Score\u2013Sports Specific Subscale.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Fifty patients (34 females and 16 males) were included in this study. There were 19 endoscopic repairs and 31 open repairs. Within the cohort, 52.0% had a full-thickness tendon tear on magnetic resonance imaging, and 48.0% had a partial tear. Average follow-up time was 58.07 \u00b1 37.27 months (mean \u00b1 SD; range, 24-220 months). The mean age and body mass index of the group were 46.13 \u00b1 13 years and 25.43 \u00b1 5.14. The average time from injury to surgery was 66.73 weeks (range, 5.14-215.14 weeks). Average postoperative PROs were as follows: modified Hip Harris Score, 91.94 \u00b1 9.96; Non-arthritic Hip Score, 91.33 \u00b1 9.99; iHOT-12, 87.17 \u00b1 17.54; Hip Outcome Score\u2013Sports Specific Subscale, 87.15 \u00b1 18.10; and VAS, 1.16 \u00b1 1.92.
