In this retrieval study, researchers from Dartmouth University investigated the following hypotheses: (1) highly cross-linked UHMWPE bearings produced by all protocols have the potential to oxidize in vivo, and (2) annealed highly cross-linked UHMWPE has a greater potential to oxidize in vivo than remelted highly cross-linked UHMWPE. Differences in postirradiation thermal processing of highly cross-linked UHMWPE were shown to lead to differences in oxidation resistance of HXL bearings in vivo.
