The aim of this study is to demonstrate that stress induced by the in vivo joint forces on EtO sterilised UHMWPE components is responsible of an increased oxidation of the material. The experimental data collected in this study indicate that, as expected, there is a correlation between the observed global wear and in vivo time, although anatomic conditions, patient activity and retrieval motivations could seriously affect the reproducibility of the phenomenon in such a differentiated sample outline.

Abstract

The aim of this study is to demonstrate that stress induced by the in vivo joint forces on EtO sterilised UHMWPE components is responsible of an increased oxidation of the material. The experimental data collected in this study indicate that, as expected, there is a correlation between the observed global wear and in vivo time, although anatomic conditions, patient activity and retrieval motivations could seriously affect the reproducibility of the phenomenon in such a differentiated sample outline.
