Abstract

The present invention relates to a medical implant for cartilage and/or bone repair at an articulating surface of a joint. The implant comprises a contoured implant body and at least one extending post. The implant body has an articulating surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the said articulating and bone contact surfaces face mutually opposite directions and said bone contact surface is provided with the extending post. A cartilage contact surface connects the articulating and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The articulating surface has a layer that consists of titanium nitride (TiN) as the wear-resistant material. The cartilage contact surface has a coating that substantially consists of a material having chondrointegration properties.
