Oxidation and degradation of polyethylene cups in hip joint prostheses

Abstract

The properties of polyethylene cups of hip prostheses produced by Johnson & Johnson Orthopaedics, De Puy International Ltd. (Great Britain) and Aesculap AG & Co. KG (Tuttlingen, Germany), removed after various times of implantation due to their premature wearing out, were compared by means of the analysis of FT-IR spectra and determination of the hardness and viability of macrophages and osteoblasts. The oxidation of polyethylene was found to be a main reason of Aesculap cups' damages.
