摘要：
An orthopaedic implant can replace a joint in a patient. The orthopaedic implant includes a first component having a first component surface and a second component having a second component surface. The first component surface and the second component surface mate at an interface. The first component surface includes a metal substrate, a nanotextured surface, a ceramic coating, and a transition zone. The nanotextured surface is disposed directly upon the metal substrate and has surface features in a size of 10−9 meters. The ceramic coating conforms to the nanotextured surface and includes a plurality of bio-active sites configured to attract and retain calcium and phosphorous cations. The transition zone is disposed between the metal substrate and the ceramic coating. The transition zone includes a concentration gradient transitioning from the metal substrate to the ceramic coating and there is no distinct interface between the metal substrate and the ceramic coating.
