Endoscopic Proximal Hamstring Repair Is Safe and Efficacious With High Patient Satisfaction at a Minimum of 2-Year Follow-Up

Abstract

To evaluate the short-term outcomes of endoscopic proximal hamstring repair including clinical outcomes, patient-reported outcomes, and complications. A retrospective analysis was performed on consecutive patients who underwent endoscopic proximal hamstring repair from 2013-2018 by a senior sports medicine orthopaedic surgeon. Demographic, operative, clinical data, complications, and patient-reported outcomes were collected and analyzed including the International Hip Outcome Tool-12 (iHOT-12), Single Assessment Numeric Evaluation (SANE), modified Harris Hip Score (mHHS), and the Hip Outcome Score activities of daily living scale (HOS-ADL). Thirty patients were included with a minimum 24.0- and average 44.0-month follow-up. The average age was 52.0 years (standard deviation [SD], 14.2), and 80.0% (n= 24) were women. Most patients presented with a history of refractory insertional tendinosis (83.3%, n= 25) and an average of 34.0 months of symptoms prior to surgical intervention. Two-year patient-reported outcomes were clinically acceptable with a postoperative iHOT-12 of 81.9 (SD, 21.1), SANE 78.8% (SD, 20.0), mHHS 89.6 (SD 13.4), and HOS-ADLs 87.2% function (SD, 15.9). Nine patients (30%) had available preoperative iHOT-12 scores. Among these patients, the mean increase in iHOT-12 was 46.3 (P= .0005; n= 9). Eighty percent (n= 24) of patients achieved the iHOT-12 patient acceptability symptomatic state. Complications (3%) included 1 atraumatic rerupture. Four patients participated in an organized sport and 18 in recreational sport with a return to play of 100% and 72.2%, respectively. All patients returned to work. Some 76.7% (n= 23) of patients reported return to their baseline level of physical activity, and 73.3% (n=22) of patients reported complete resolution of pain at last follow-up. There was a 90.0% (n=27) satisfaction rate. Short-term follow-up for endoscopic proximal hamstring repair shows high patient satisfaction (90.0%) and clinically significant patient-reported outcomes with minimal residual pain and a low complication rate (3%).
