Metal-on-metal hybrid hip resurfacing arthroplasty has been performed more frequently in recent years1,2. Its resurgence is attributed to a better understanding of metallurgy and to stricter tolerances with regard to the design of the metal-on-metal articulation. One currently used device is the Cormet hip resurfacing system (Corin Group, Cirencester, Gloucestershire, United Kingdom), a metal-on-metal implant with a cemented femoral component and a press-fit uncemented acetabular component. The cobalt-chromium acetabular component is coated with plasma-sprayed unalloyed titanium and overlaid with hydroxyapatite3.
