title: Management strategies for acetabular defects in revision total hip arthroplasty.
abstract: The management of failed acetabular implants in total hip arthroplasty revision surgery requires an algorithm for intraoperative decisions regarding technique and implant selection. When > or = 50% of the acetabular host-bone is intact and stable, a press-fit ingrowth socket offers a reliable solution. In the presence of peripheral, central, or combined defects, a reconstruction ring with compacted cancellous allograft is advised.
