Excerpt
Hip surgeons and material scientists agree that while reducing bearing-surface wear after THA is important, the real goals are to prevent osteolysis and aseptic loosening. Most hip replacements are performed using highly crosslinked polyethylene (XLPE) liners, since many surgeons are concerned about problems associated with ceramic-on-ceramic and metal-on-metal (MoM) bearings, including squeaking and ceramic fractures for the former [
1], and elevated serum ion levels from (MoM) couplings with the latter [
6]. …
