Cementless hip replacement for arthritis. Problems with a smooth surface Moore stem.
We have analysed the clinical results of a cementless hip replacement using a Moore stem with a smooth surface, and correlated these results with the radiological changes. Forty-two consecutive arthroplasties in 41 patients were studied prospectively and reviewed at a minimum of two and up to six years; 63% had a good clinical result, 18.5% a fair result, and 18.5% a poor result. Thigh pain on weight-bearing was the main problem and was due to loosening of the stem. We caution against the use of this implant in arthritic patients, in whom a good result can be obtained more predictably with cement fixation.
