RESUMO
Arthroscopic release of the iliopsoas tendon for iliopsoas impingement (IPI) after total hip arthroplasty (THA) at the lesser trochanter gives good results. However, where IPI then recurs, due to adhesions between the healing iliopsoas tendon and the surrounding soft tissue, and nonoperative measures have failed, a revision THA procedure is usually considered. We propose a technique of arthroscopic visualization of the recurrent IPI and a subsequent psoas tenotomy at the level of the hip joint using an outside-in capsulotomy approach. This secondary tenotomy, located proximally directly at the level of the recurrent impingement, allows relief of the painful symptoms without compromising the muscle function of the iliopsoas and precludes the need for a complex THA revision.
