Hip implants made of crosslinked ultra high molecular weight polyethylene—PE‐UHMW—(different as‐received conditions) are compared with a retrieval made from non‐crosslinked PE‐UHMW and a control PE‐UHMW. Oxidation leads to recrystallization and the enhanced crystallinity corresponds to higher hardness values. These structure‐property relations are discussed for conventional PE‐UHMW and also for crosslinked material.
