ABSTRACT
PURPOSE:
To evaluate the average ten-year follow-up results of 98 total hip arthroplasties using Harris-Galante-II porous-coated acetabular components. MATERIALS ANDMETHODS:
Ninety-eight hips were evaluated. The mean age of the patients was 45 years, and the mean follow-up was 121 months. The clinical and radiographic findings including the wear of the polyethylene liner were evaluated. The endurance of the acetabular component was analyzed using the Kaplan-Meier method.RESULTS:
Retroacetabular osteolysis, dissociation of the PE liner and aseptic loosening of the acetabular component was observed in 25 hips (25.5%), 9 hips (9.2%), and 1 hip (1.0%), respectively. The average rate of liner wear was 0.16 mm/year. Twenty acetabular components (20.4%) were revised, and the survival probability of the acetabular components at 10 years was 87% (95% confidence limits, 83-90%).CONCLUSION:
In this long-term follow-up study, the revision rate of Harris-Galante-II acetabular component was relatively high, and was associated with locking mechanism failure and retroacetabular osteolysis. However, the rarity of aseptic loosening suggests that excellent long-term fixation could be achieved with the surface treatment of a fiber-metal porous coating.
