The Harris Design-2 total hip replacement fixed with so-called
second-generation cementing techniques. A ten to fifteen-year follow-up. J
Bone Joint Surg Am. 1998;80:1775-80.
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. See Instructions
to Authors for a complete description of levels of evidence.
