[Iliopsoas impingement after cementless total hip arthroplasty. Case reports]. / Iliopsoaskontaktphänomen nach zementfreier Hüfttotalendoprothese. Eine Fallbeschreibung.

ABSTRACT

Postoperative pain after total hip arthroplasty can be caused by several conditions. We describe two cases of postoperative persistent iliopsoas impingement after cementless implantation of the acetabular component. The groin pain was relieved after revision with a more anteverted acetabular component. We describe the diagnostic methods as well as the principles of the revision.
