The purpose of this study was to investigate the damage mechanisms and oxidative stability of remelted polyethylenes in a consecutive series of retrieved tibial components. Posteriorly stabilized tibial components were retrieved at consecutive revision surgeries at 7 different surgical centers. Remelted highly crosslinked polyethylenes proved to have reduced oxidation indices as compared with conventional inserts.
