Abstract
Twenty patients with osteonecrosis of the femoral head underwent 28 total hip arthroplasties using cement from 1981 to 1985. Femoral reconstruction was by use of second-generation cement techniques. Twenty-four hips in 17 patients were available for review at a mean follow-up period of 7.7 years. The mean age at surgery was 55 years. Clinical evaluation demonstrated 79% excellent, 4% good, and 4% fair results. Three hips (12.5%) required revision for loosening. The cumulative probability of survival was estimated to be 85.7% at 10 years. Second-generation cement techniques and implant designs did improve the clinical results in this high-risk group; however, the overall mechanical failure rate remained high.
