Forty-nine total hip arthroplasties in patients under 40 years of age, were assessed clinically and radiologically two to eight years after operation. Clinical results were evaluated according to the Harris hip score system. At the final follow up, 45 hips(92 per cent) were excellent or good, 2 hips were fair, and 2 hips were poor. Two patients with poor results were revised. Radiological examination showed migration of acetabular component in 5 hips and subsidence of the femoral stem in 2 hips. In conclusion it is clear that hip arthroplasty provides patients with freedom from pain and excellent function. Recent advances, including the change to cementless fixation and improvement in operation technique, may well lead to still better results in the future.
