ABSTRACT
One hundred seven total hip arthroplasties were done between 1991 and 1992 with ALIZE acetabular cup with hydroxyapatite coating (Biomet France, Valence, France) and AURA hydroxyapatite-coated stem (Biomet France) in 107 patients. The articulation was ceramic on polyethylene for 102 patients and metal on polyethylene for the remaining 5 patients. The mean follow-up of the series was 8.4 +/- 2.5 years. The mean preoperative Merle d'Aubigné hip functional score was 10.6 +/- 3 vs 15.8 +/- 1.8 at the latest follow-up. Sixty-three patients were alive for the long-term follow-up at a mean of 9.67 +/- 0.25 years. Of the patients, 98.5% were satisfied or very satisfied at the latest follow-up. Five revisions were documented in these series 1 for acetabular loosening, 2 for traumatic ceramic head fracture, 1 for polyethylene replacement, and 1 for stem replacement due to bone fracture. The mean wear rate was 0.076 +/- 0.043 mm/y (<0.1 mm/y considered as the normal wear rate). The overall survival rate at 10 years was 95.6% +/- 2.1% using revision of either component as the end point.
