Results

At last follow-up, 7 hips showed failure both clinically and radiographically. Of these, 4 had been revised (stem only in 1, cup only in 2, and both stem and cup in 1). All failures occurred between 2 and 5 years postoperatively. Three patients had radiographic evidence of loosening,[8,9,10,11,12,13] as well as pain and clinical failure.[6] Two of them had radiographic evidence of stem subsidence and had pain with weight-bearing and passive range of motion. One patient had radiographic evidence of stem subsidence and a change in position of the cup, as well as pain on weight-bearing and passive range of motion. These 3 patients were awaiting revision surgery.

The 13 patients without either clinical or radiographic signs of loosening had an average follow-up of 42 months (11 to 58 months). The average hip score[6] at last follow-up was 89.6 (range, 53 to 100). Results were rated as excellent in 8 (61%), good in 4 (31%), and poor in 1 (8%).

The overall failure rate (radiographic loosening of at least one component, clinical failure, and/or revision surgery) was 35% at an average follow-up of 42 months. The femoral component failed at an overall rate of 25% and the acetabular component at an overall failure rate of 20%.
