Iliopsoas impingement refers to the painful contact between the iliopsoas tendon and the anterior acetabular rim of the hip joint. This mechanism can occur in the native hip as part of an internal snapping hip syndrome and, in particular, following total hip arthroplasty, leading to chronic groin pain and a substantial reduction in the quality of life. This review article outlines the diagnostic approaches for identifying iliopsoas impingement and presents both established open procedures and innovative minimally invasive arthroscopic techniques for iliopsoas tendon release, in order to facilitate precise treatment planning and avoid potential complications.
