Cementless total hip arthroplasties using ceramic-on-ceramic articulation in young patients. A minimum 5-year follow-up study.

Abstract

Cementless total hip arthroplasties were performed in 25 consecutive young patients (27 hips), with a mean age of 36.5 years, using prostheses that offered ceramic-on-ceramic articulation. The median follow-up period was 75 months, with all hips being followed a minimum of 5 years. Revision surgery was necessary in one hip at 60 months for fracture of the cup. Ninety-six percent of the remaining hips were rated good or excellent clinically using the Harris hip scale. Radiographic loosening of one or both components was evident in 3 hips. There was no incidence of femoral or acetabular osteolysis observed at follow-up periods of 5 to 8 years.
