Wear of Highly Crosslinked Polyethylene against Cobalt Chrome and Ceramic femoral heads
There is increasing interest in the use of highly cross-linked polyethylene with large diameter heads in the hip. This study investigated the wear characteristics of size 36 mm ceramic and cobalt chrome femoral heads articulating against highly cross-linked polyethylene inserts using a physiological hip simulator. The steady state wear rate of the ceramic femoral heads articulating against highly cross-linked inserts was found to be 50% lower than that of cobalt chrome femoral heads.
