Patent ID: 8657822

Claim:
A surgical kit for cartilage repair at an articulating surface of a joint, comprising: a medical implant, comprising a substantially plate shaped implant body, wherein the plate shaped implant body has a predetermined cross-section that preferably substantially corresponds to the area of the damaged cartilage; and a set of tools with: a guide tool comprising a guide body with a guide channel, wherein the guide channel has a cross-sectional profile and a muzzle on the cartilage contact surface at a position corresponding to the site of the diseased cartilage; and an insert tool with a cross-sectional profile that is designed to correspond to the cross-sectional profile of the guide channel with a tolerance enabling the insert tool to slide within the guide channel, wherein said medical implant comprises an extending post having a cross-sectional area for securing the implant in a drilled hole of the bone, said guide tool comprising a positioning body and a guide body with a guide channel which goes through said positioning body and guide body, wherein the positioning body has a cartilage contact surface that is designed to fit the contour of the cartilage or subchondral bone in the joint in a predetermined area surrounding the site of diseased cartilage and wherein the cartilage contact surface is formed such that it uses the curvature in the cartilage surface in the joint for stability in order to give adequate support and stable positioning of the guide tool in the joint and at the same time maximum support and positional stability for the positioning body on the site of the injury compared to the cartilage contact surface and wherein the guide body is extending from a top surface.
