Abstract
Patients with THA using a ceramic head and using an OxZr head were each matched to patients with a CoCr head. Mean implantation time was 5 years. There was no difference in steady state wear rate between the ceramic (0.066â¯Â±â¯0.050 mm/year) and CoCr match groups (0.052â¯Â±â¯0.041â¯mm/year), or between the OxZr (0.022â¯Â±â¯0.029â¯mm/year) and CoCr match groups (0.048â¯Â±â¯0.071â¯mm/year). Follow-up into the second decade will be necessary before any changes in THA wear rate from using ceramic or OxZr bearings may be appreciated clinically with available imaging techniques.
