Abstract
BACKGROUND: Partial avulsions of the proximal hamstring origin remain a challenging problem with nonoperative treatments frequently providing limited success. The literature is limited regarding the outcomes of operative management in the active and athletic population. HYPOTHESIS: Surgical fixation of proximal hamstring ruptures will have favorable outcomes at midterm follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 64 patients with partial avulsions of the proximal hamstring origin treated with surgical fixation by a single surgeon were reviewed at a 2-year minimum follow-up. All patients had initially undergone failed nonoperative treatment. Patient-reported outcome scores on the Lower Extremity Functional Score (LEFS), Marx Activity Rating Scale, custom LEFS and Marx scales, and total proximal hamstring score were evaluated. Data on patient-perceived strength, return to sport, and satisfaction were also collected. RESULTS: The cohort included 27 male and 37 female (N = 64) patients with a mean age of 47.3 years (range, 16-65 years), and all were reviewed at a mean 6.5-year (range, 2-12.5 years) follow-up. The average postoperative LEFS was 96% (range, 68%-100%), with the custom LEFS being 90% (range, 39%-100%). The mean Marx score was 12.4 (range, 4-16). The Marx custom score demonstrated no disability with activities of daily living. The mean total proximal hamstring score was 94% (range, 69%-100%). No differences in any outcome measures were seen when comparing acute versus chronic repairs. Three patients underwent further hamstring surgery. No patients reported symptoms of numbness in the operative extremity at rest, while 3 patients had a superficial stitch abscess treated with antibiotics alone. The most commonly reported difficulty was with prolonged sitting. Ninety-seven percent were satisfied with surgery, 92% reported they could participate in strenuous activity, and 97% estimated their strength to be >75%, while 64% estimated it to be 100% of their contralateral side. Patients returned to sport at an average of 11.1 months, and all that returned were satisfied with their performance. CONCLUSION: Both early and delayed anatomic surgical repair of partial proximal hamstring avulsions leads to successful functional outcomes, a high rate of return to athletic activity, and low complication rates at the 6.5-year follow-up. Nonoperative treatments should first be attempted.
