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.
