Wear versus Thickness and Other Features of 5-Mrad Crosslinked UHMWPE Acetabular Liners

Abstract

The low wear rates of crosslinked polyethylenes provide the potential to use larger diameters to resist dislocation. However, this requires the use of thinner liners in the acetabular component, with concern that higher contact stresses will increase wear, offsetting the benefits of the crosslinking.
