Our "Remodeling simulation" has been developed to evaluate the endurance performance of artificial hip joints by numerical simulation. "Remodeling simulation" was taken into consideration the bone remodeling phenomena that the bone was absorbed or adapted by the stress conditions. We could evaluate the relationship between bone remodeling phenomena occurred around hip joints and design parameters of them. In addition, we have assessed the scheme for evaluation of the endurance performance of artificial hip joints by numerical analysis based on the finite element analysis (FEA). The endurance performance of hip stems has been assessed by the experimental method established on ISO standards. Computer simulations can reduce the cost and time required on experiments, furthermore, it is possible to evaluate the mechanical performance of hip joints under various conditions. Therefore, the computer simulation should be an effective tool to advance the mechanical performances of artificial hip joints and the QOL of patients.
