Effect of Roughened Counterpart on Behaviors of Vitamin E Infused Ultra-High Molecular Weight Polyethylene

摘要

The wear debris accumulating around joint prostheses increase the risks to make bearing surfaces roughened. In present study the counterparts with rough surfaces increase wear generation of El to some extent. But in contrast to conventional UHMWPE, vitamin E infused UHMWPE is proven to have the excellent wear-resistance ability. Moreover the roughened counterpart has less effect on roughness of El.
