Abstract Purpose This study aims to evaluate the clinical outcomes of patients who underwent endoscopic transcapsular iliopsoas tenotomy for painful snapping hip syndrome at minimum of ten years follow‐up. Methods This is a monocentric retrospective study on a consecutive series of patients undergoing endoscopic transcapsular iliopsoas tenotomy procedure for painful snapping hip syndrome between January 2012 and June 2015. Included patients were clinically evaluated at a minimum of ten years of follow‐up. Perioperative, early or late complications and adverse events were recorded. Modified Harris Hip Score (mHHS) and Hip Disability and Osteoarthritis Outcome Score (HOOS) were calculated preoperatively, at 1 year, and after 10 years postoperatively. Hip flexion strength was assessed preoperatively and at 1 month, 6 months, 1 year and after 10 years postoperatively. Results Twenty patients were included in the study. No patient was lost to follow‐up at a minimum of 10 years. Mean follow‐up was 10.6 years. No perioperative complications were reported. No serious or minor adverse events were recorded. None of the patients required revision hip arthroscopy or was scheduled for total hip arthroplasty at the last follow‐up. Three patients (15%) exhibited hip flexion weakness on clinical examination and in these patients MRI revealed iliopsoas muscle atrophy. Three patients (15%) reported persistent snapping during hip flexion‐extension. No sensory deficits were observed. Both mHHS and HOOS were significantly improved ( p < 0.001) at the last follow‐up. Conclusions Endoscopic transcapsular iliopsoas tenotomy is a safe and effective procedure for snapping hip syndrome at long‐term follow‐up. Level of Evidence Level IV.
