Uncemented total hip replacement and thigh pain

Summary. We reviewed 145 consecutive patients who had total hip replacements using uncemented CLS Spotorno femoral stems which achieve primary fixation with bony ingrowth which occurs later mainly in the metaphyseal region. The mean age was 54.9 years and average follow up 7.8 years. The Merle d’Aubigne and Harris hip scores were used for evaluation, together with plain radiographs. Current medium term follow up showed a survival rate of 96.7% and a good functional score in more than 90%. Special attention was paid to postoperative thigh pain which occurred in only one patient. These results are encouraging, but a follow up of more than 10 years is required before comparable results to cemented stems can be claimed.
