Effect of sliding-taper compared with composite-beam cemented femoral prosthesis loading regime on proximal femoral bone remodeling: a randomized clinical trial

This report has been verified by one or more authors of the original publication.

120 patients were randomized to evaluate whether the geometry of the cemented femoral prosthesis affected the pattern of strain-adaptive bone remodelling in the proximal aspect of the femur following total hip arthroplasty (THA). Patients received either composite-beam or sliding-taper (double and triple-tapered) prostheses and were assessed at 2 years. Results indicated that the magnitude and regional distribution of proximal femoral bone loss were similar between patients who received sliding-taper or composite-beam prostheses. Furthermore, similar bone remodeling pattern was observed between double and triple-tapered prostheses.
