Abstract Groin pain after total hip replacement is an uncommon event and may be the result of several causes, including iliopsoas impingement. We describe the case of a 51‐year‐old woman who was diagnosed with iliopsoas impingement after total hip replacement with a collared femoral stem. She did not improve despite extensive conservative treatment. She was treated by endoscopic iliopsoas tenotomy, and the surgical technique is described herein. Her preoperative groin pain and popping disappeared completely at 3 months postoperatively. Technique Video video See video under supplementary data.
