Total Hip Arthroplasty After Operatively Treated XXXX : A Concise Follow-up, at a Mean of Twenty Years, of a Previous Report.

UNASSIGNED: @entity174 increase the risk of posttraumatic @entity625 and thus the risk of @entity572 ( @entity572 ). We previously presented the ten-year results of @entity572 performed for posttraumatic @entity625 after an @entity174 ; we now present the twenty-year outcomes. The original publication included sixty-six @entity1 who underwent @entity572 between 1970 and 1993 for posttraumatic @entity625 after open reduction and internal fixation (ORIF) of an @entity174 . Clinical outcomes, implant survivorship, radiographic results, and complications were evaluated. A total of thirty-six @entity1 had died. The mean Harris hip score was 80 at the latest follow-up. Nineteen acetabular and/or femoral components had been revised: eleven for @entity1349 , seven for @entity3061 , and one for instability. Twenty-year survivorship of the acetabular component was 71% free from revision for @entity1349 and 57% free from revision for any reason. @entity572 after ORIF of an @entity174 was associated with fair implant survivorship at twenty 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 twenty years were @entity1349 and @entity3061 . LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
