1. A method of designing or selecting an articular implant for repairing articular cartilage of a joint, the articular implant having an inner surface for facing bone and an outer surface for facing a cavity of a joint, the method including:
- obtaining an image of a joint, the image including shape information of at least one of subchondral bone and cartilage;
deriving the shape of the at least one of subchondral bone and cartilage from the image; and
designing or selecting the articular implant with both the inner and the outer surface of the implant based, at least in part, on the derived shape, wherein the articular implant includes an attachment mechanism for fixing the articular implant to the joint.
