Antero-posterior radiograph of a PSR CCD design (Zimmer, Warsaw, IN) 20 years after implantation. Polyethylene wear is suggested by the asymmetric position of the femoral head with respect to the acetabular component. However, there are no osteolytic lesions visible and the component fixation is pristine. The patient UCLA activity score remained moderate throughout the follow-up period with a maximum value of 7. The reconstruction still has not been revised 25 years after surgery.
