Total Hip Arthroplasty for Posttraumatic Osteoarthritis of the Hip Fares Worse Than THA for Primary Osteoarthritis

摘要

We conducted a study to evaluate differences between patients who had total hip arthroplasty (THA) for post-traumatic osteoarthritis (OA) and patients who had THA for primary OA.Using a prospective database, we followed 3844 patients who had THA for OA. Those who had THA for secondary causes of hip OA, developmental hip dysplasia, or inflammatory processes were excluded. Of the remaining 1199 patients, 62 (63 fractures) had THA for posttraumatic OA after previous acetabular or proximal femur fracture fixation, and 1137 had THA for primary OA and served as the control group.
