    IntroductionPrior studies of hamstring tendon tears have reported varied findings on whether increased delay from injury to surgery is associated with worse outcomes. The purpose of this study was to determine whether increased time from injury to surgical repair is associated with worse clinical outcomes in patients with proximal hamstring ruptures.Materials And MethodsPatients who underwent surgical repair of a proximal hamstring rupture from 2010 to 2019 were followed for a minimum of 24 months from surgery. A cutoff of 6 weeks from injury to the time of surgery was used to distinguish between acute and chronic ruptures. All patients completed patient-reported outcome measures (PROs) at the final follow-up. Multiple factors were analyzed for their effects on PROs including time to surgery, amount of tendon retraction, and demographics such as sex and age.ResultsComplete data sets were obtained for 38 patients at a mean follow-up of 4.9 years. All data is reported as a mean ± standard deviation. Patients who underwent acute repair of proximal hamstring ruptures had significantly greater Perth Hamstring Assessment Tool (PHAT) scores than those who underwent chronic repair (76.9 ± 18.8 vs 60.6 ± 18.2, p = 0.01). Increased time to surgery was significantly correlated with worse PHAT scores (ρ = - 0.47, p = 0.003). There was no difference in PROs based on the amount of tendon retraction, number of tendons torn, sex, smoking status, or BMI.ConclusionsThis study found that acute repair performed within 6 weeks of injury appears to yield improved PROs compared to chronic repair. These data highlight the importance of timely and accurate diagnosis of proximal hamstring ruptures and early operative intervention for surgical candidates.© 2022.
