Fifteen-year survivorship of uncemented Harris-Galante I acetabular cup

Abstract

We studied the long-term outcome of uncemented total hip arthroplasty using HG-I components in 90 hips (80 patients) with an average age of 57.5 years who were operated on between 1984 and 1986 at our institution. Average follow-up was 14.9 years and no patient was lost to follow-up. Hip scores improved significantly and there was clinical and radiographic evidence of bony ingrowth on the acetabular components in all patients. There were eleven revisions in the study population for reasons related to failure of femoral component (eight hips), acetabular liner dissociation (two hips) and deep infection (one hip). At the latest follow-up, three femoral components were determined to be loose. No acetabular component was revised for aseptic loosening. In addition to the revisions there were two reoperations, one for psoas tendon release, and one for excision of heterotopic ossification. Thus, the survivorship free of revision and free of mechanical failure for the acetabular component at 15 years was 95.7% (95% CI: 0.89–1.0) and 91.9% (95% CI: 0.83–0.98) respectively. The survivorship at 15 years for the femoral component was 86.8% (95% CI: 0.78–0.95) free of revision and 82.0 % (95% CI: 0.71–0.92) free of mechanical failure.
