title: Revision Total Hip Arthroplasty: The Acetabular Component.
abstract: Intermediate and long-term results of revision total hip arthroplasty performed with the use of a cemented acetabular component have been disappointing, with high rates of radiographic and clinical failure. Other methods of acetabular revision involving the use of threaded cups and bipolar implants have also met with high failure rates. Although the long-term results of revision arthroplasty with uncemented acetabular components, especially in terms of polyethylene wear and pelvic osteolysis, are not yet available, the intermediate results have been excellent.
