Abstract:
The present invention presents methods for making oxidation-resistant and wear-resistant polyethylenes and medical implants made therefrom. Preferably, the implants are components of prosthetic joints, e.g., a bearing component of an artificial hip or knee joint. The resulting oxidation-resistant and wear-resistant polyethylenes and implants are also disclosed.
