Abstract

This study evaluated the hypothesis that the clinical results are equivalent in the group of patients with dysplasia, low dislocation, and high dislocation types using a contemporary technique for hip arthroplasty. The mean age of patients at the time of the index operation was 49.5 years (range, 29-61 years). Thirty patients (40 hips, 35%) had dysplasia, 22 (34 hips, 29%) had a low dislocation, and 24 (42 hips, 36%) had a high dislocation. The mean follow-up was 9.7 years (range, 6-14 years). In the high dislocation group, 7 hips (17%) had a revision of one or both component. In low dislocation group, 3 hips (9%) had a revision of one or both components. In the dysplastic group, 2 hips (5%) had a revision of one or both components.
