The relationship between wear and oxidation in total knee replacement (TKR) prostheses was investigated. It was apparent from the retrievals that delamination can be correlated with regions of high subsurface oxidation. In some specimens, however, delamination occurred predominantly under the wear track and was not associated with post-irradiation damage. In some instances, delamination cracks occurred in regions below the white band. Post-irradiation damage resulting in subsurface oxidized regions does correlate with delamination of TKR. However, in some cases it appeared that delamination could occur where oxidation was minimal.
