Acetabular fractures increase the risk of posttraumatic arthritis and thus the risk of total hip arthroplasty (THA). We previously presented the 10-year results of THA performed for posttraumatic arthritis after an acetabular fracture; we now present the 20-year outcomes. The original publication included 66 patients who underwent THA between 1970 and 1993 for posttraumatic arthritis after open reduction and internal fixation (ORIF) of an acetabular fracture. Clinical outcomes, implant survivorship, radiographic results, and complications were evaluated. A total of 36 patients had died. The mean Harris hip score was 80 at the latest follow-up. 19 acetabular and/or femoral components had been revised: 11 for aseptic loosening, 7 for osteolysis, and one for instability. 20-year survivorship of the acetabular component was 71% free from revision for aseptic loosening and 57% free from revision for any reason. THA after ORIF of an acetabular fracture was associated with fair implant survivorship at 20 years after surgery. It is possible that newer implants with improved fixation surfaces and bearing materials may enhance long-term results, as the most common reasons for failure at 20 years were aseptic loosening and osteolysis.
