The design and manufacture of ceramic implants has improved significantly over the last decade. Consequently the use of ceramic-on-ceramic bearings in total hip replacement has become increasingly popular with over 150,000 components having been implanted in Europe [1]. This increased use and uptake of the ceramic-on-ceramic combination can be thought to reflect the low wear rates that it has exhibited as a bearing couple [2-4]. In addition to these lower wear rates; ceramic-on-ceramic bearings have a subsequent reduced incidence of osteolysis, the possibility to be used in smaller cups without increasing wear, and the absence of any metal ion production.
