Excerpt
Polyethylene wear is a key factor in osteolysis and a determinant for subsequent revisions [
6]. To combat polyethylene wear, researchers developed new materials such as highly-crosslinked polyethylene (HXLPE), which in turn, allowed for the use of large femoral heads. It appears that use of this material in practice has lowered the average wear rate. However, it is of particular interest to understand why certain patients have higher than expected wear rates and require revision surgery. …
