The twenty to twenty-five-year outcomes of the harris design-2 matte-finished cemented total hip replacement - A concise follow-up of a previous report

We previously reported the ten to fifteen-year results for 195 matte-finished Harris Design-2 total hip replacements that had been inserted with cement by two surgeons in 166 patients with osteoarthritis. The purpose of the present report is to update that study and report the twenty to twenty-five-year outcomes. The patients were followed prospectively on the basis of clinical assessment with use of the Harris hip score and radiographic analysis. One hundred and forty-nine patients (90%) had a functioning implant at the time of death or, if living, at twenty to twenty-five years of follow-up. A total of ten patients (ten hips; 5%) underwent a revision because of aseptic loosening of the acetabular component (two hips; 1%), the femoral component (four hips; 2%), or both components (four hips; 2%). At twenty-five years, Kaplan-Meier analysis revealed a survival rate of 83% +/- 6% with revision for any reason as the end point. The survival rate was 86% +/- 6% for the femoral component and 93% +/- 3% for the acetabular component with aseptic loosening as the end point. Level of Evidence: Therapeutic Level IV.
