| Research Abstract |
The ultra highly molecular weight polyethylene (UHMWPE) liner used in total hip replacement. Recently, thinning of thickness and large-diameter of liner is progressing for the range of motion improved. In this study, hip simulator test had run by using 3.5/4.0mm thickness 44mm diameter PE liner under standard simulator test conditionsup to 5 million cycles. Compared to non doped PE liner, There was no wear advantage related to 0.1% alpha-tocopheral (0.1% by weight) doped cup.
