ABSTRACT
Abstract: We previously reported our results at a minimum of three and seven years after use of a porous-coated acetabular metal shell in a consecutive series of 138 revision total hip arthroplasties. The current report presents the longer-term outcomes of these procedures, at fifteen to nineteen years postoperatively. A total of twenty metal shells (14%) underwent repeat revision. Seven of the repeat revisions were performed because of recurrent dislocation, seven were done at the time of femoral revision surgery, and six were done because of infection. Nineteen of the revised shells were well fixed, and one was aseptically loose. Of the sixty-seven hips in which the acetabular component survived for more than fifteen years after the index operation, two (3%) required a change of the modular acetabular liner because of wear or osteolysis. Nine (16%) of the fifty-seven hips with at least fifteen years of radiographic follow-up had an osteolytic lesion of >1 cm in diameter. The fifteen-year survival rate of the metal shells, with failure defined as revision because of loosening or as radiographic evidence of loosening, was 97%. Revision total hip arthroplasty with this cementless acetabular component has been followed by excellent component survivorship at fifteen years; the most common reasons for repeat revision were recurrent dislocation and infection.
