Abstract 

The results of 498 total hip arthroplasties were prospectively studied. In 329 patients a cemented acetabular polyethylene cup was inserted. In 169 patients a threaded socket without cement was introduced. Follow-up ranged from 6 to 8 years and follow-up rate was over 90%. Of the 169 threaded sockets 8 required revision (4.7%), and 3 acetabular components were seen to be loose on X-ray. Of the cemented cups, only 2 (0.6%) required revision and none were considered loose on X-ray.
