Abstract
Despite overall good survivorship and clinical outcomes in the short term after total hip arthroplasty (THA) with use of alumina ceramic-on-highly cross-linked polyethylene (HXLPE) in patients younger than 30 years of age, there is a paucity of long-term data to evaluate the fixation of the components and the prevalence of osteolysis. We reviewed the records of 45 patients (54 hips) who had been included in a previous report to evaluate the long-term functional outcomes as well as radiographic and computed tomographic scan findings (particularly with regard to component fixation and osteolysis) after a mean duration of follow-up of 17.8 years. One femoral stem was revised because of aseptic loosening, and 2 acetabular components were revised because of recurrent dislocation. The survival rate at 17.8 years was 98% for the femoral component and 96% for the acetabular component. LEVEL OF EVIDENCE:: Therapeutic Level IV.
