Abstract
There are four factors for the success of the total hip joint replacement implant surgery, that is, patient- surgical technique- implant design- and implant manufacturing. Implant design is the most critical factor and easy to perform optimization. Compatibility of dimension, contact area and material are the three crucial points in implant design. Critical contact during friction movement is one of the causes of implant damage. With the simulation software will get a mapping critical contact area to do the development of the component design.
Keywords: Simulation- prediction- friction- hip joint replacement
