Abstract: The present invention relates to a method for designing an implant comprising designing a contour curvature of the implant so that an articulating surface of the implant is designed to correspond to a simulated healthy articulating surface of a damaged articulating surface of a joint. The implant is provided with at least one positioning mark designed to be used for determining the orientation in which the implant is to be placed in a recess made in a damaged articulating surface of a joint. Further, the present invention relates to methods for positioning and inserting a medical implant in a recess.

Abstract: A method for designing an implant includes designing a contour curvature of the implant so that an articulate surface of the implant is designed to correspond to a simulated healthy cartilage surface reconstructed from a 3D model based on one or more images taken with MRI or CT-scanning of a damaged cartilage surface of a joint; and providing a positioning mark on a surface of the implant. The positioning mark is provided such that the positioning mark is parted from the center of the implant to be visible for a surgeon and is adapted to be used for indicating a rotational position of the implant to the surgeon.

Abstract: A drill tool for implant surgery including a first drill part having a first, smaller diameter for drilling a recess for an implant post and a second drill part having a second, larger diameter for drilling a recess for an implant hat is disclosed. The second drill part has one or more shape cutting edges and one or more sharp pre-cutting edges extending beyond said one or more shape cutting edges.

Abstract: A system for performing osteochondral transplantation surgery includes a harvesting guide tool for harvesting one or more osteochondral plugs and a transfer guide tool for insertion of each osteochondral plug in a damage site on an articular surface of a joint. A cartilage contact surface of each respective guide tool is adapted to follow the shape of a surface of cartilage or subchondral bone such that they conform to each other. Each respective guide tool includes one or more guide channels adapted to receive a respective surgical tool that slides within the guide channel, and is supported by the guide channel during surgery. The guide channels are configured to harvest and insert a plurality of osteochondral plugs of different sizes. The interiors of the guide channels are provided with markings for marking a rotational position of harvested plugs enabling positioning of the osteochondral plugs at a predetermined angle of rotation.
