The effect of accelerated aging on the wear of UHMWPE
Journal of Materials Science: Materials in Medicine, 2001 Oxidative degradation of UHMWPE has been found to be a cause of elevated wear rate of the polymer in total joint replacement leading to failure of these devices. In order to evaluate long term stability of polymers, various accelerated aging methods have been developed.
