It is known from previous studies that frictional temperature rise on the surfaces of artificial joints could reach high levels that make hazardous effects on surrounding tissue and lubricant around the artificial joint. For enhancement the tribological behavior of the joints, new material combinations have been tried. In this study vitamin E blended ultra-high molecular weight polyethylene (VE-UHMWPE), which is one of the new generation material, was used for acetabular inserts. These inserts were paired with CoCrMo femoral heads. For reduction of the frictional heating, testing parameters and their effects were investigated by using Taguchi method and analysis of variance. The results were analyzed by using Statistical Package for Social Science (SPSS 15.0). Also mathematical model for the temperature rise (Delta T) was developed with the help of statistical techniques.
