摘要：

A multiobjective optimization was used to solve several failure problems of cemented total hip arthroplasty. The objective functions were three; the principal stress in the bone cement, the shear stress of stem/cement interface and cement/bone interface. In the results, the cement stress was reduced by 49%, the stem-cement stress was reduced by 68%, and the cement-bone stress was reduced by 43%, compared with the basic model.
