Total hip replacement: the case for noncemented femoral fixation because of age.
Both noncemented fixation and improved cemented fixation of total hip replacements emerged to counteract the clinical and radiographic failures of early cemented procedures. A randomized clinical trial comparing a second-generation cemented with a second-generation noncemented total hip replacement demonstrated that in the medium term both implants allow excellent, disease-specific, global and functional capacity outcome measures. No significant differences existed between the cemented and noncemented implants in terms of these parameters or revision rate. Cost-to-utility analyses of both types of replacements revealed that total hip replacement is one of the most cost-effective medical interventions. Noncemented total hip replacements seem as efficacious as cemented devices in patients younger than 70 years.
