Third Body Wear of an All-Polymer, PEEK-OPTIMA™ on Ultra-High-Molecular-Weight Polyethylene Total Knee Replacement

Bioengineering
Experimental wear simulation of a PEEK-OPTIMA™ polymer-on-UHMWPE total knee replacement has shown equivalent UHMWPE wear to conventional knee replacement materials (cobalt chrome-on-UHMWPE) when tested in a clean environment. The aim of this study was to

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.
