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.
