Outcomes 7 to 10 years following total hip replacement

Summary
At 7-10 years after total hip replacement, this study will determine the incidence of bone loss around a primary total hip prosthesis with a metal head and polyethylene liner, as determined by CT, as well as the wear of the polyethylene and the movement of the acetabular cup, as determined by plain radiographs. The study will also examine the incidence of dislocation and other symptoms of hip instability, as well as the reasons for revision or re-operation. In addition, the study will show if there are any differences in these outcomes between prostheses with standard 28 mm and large 36 mm femoral heads.
