title: Case report: analysis of an ultra-high-molecular-weight polyethylene acetabular cup retrieval at 41 years.
abstract: A polyethylene cup explanted after 41 years was examined using several analytical techniques to determine whether there was a material cause for the extremely low wear observed. Neither the amount of polyethylene oxidation nor crystallinity appeared to be a factor.
