SYSTEM, GUIDE TOOLS AND DESIGN METHODS RELATED THERETO FOR PERFORMING OSTEOCHONDRAL TRANSPLANTATION SURGERY IN A JOINT

摘要

A system for performing osteochondral transplantation surgery in a joint is provided. The system comprises a harvesting guide tool (100) for harvesting one or more osteochondral plugs, a transfer guide tool (200) for insertion of each osteochondral plug in a damage site (51) on an articular surface of the joint, for example a knee joint (50). A cartilage contact surface (110, 210) of each respective guide tool is adapted to follow the shape of a surface (120, 220) of a cartilage or subchondral bone in a joint. The cartilage contact surface and the surface of the cartilage or subchondral bone conform to each other. Each respective guide tool comprises one or more guide channels (130, 230) adapted to receive a respective surgical tool such that the respective surgical tool 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. T he interiors of the guide channels (130) of the harvesting guide tool (100) are provided with marking means for marking a rotational position of harvested plugs. The guide channels (230) of the transfer guide tool (200) are adapted to position the osteochondral plugs at a predetermined angle of rotation.
