A surgical kit for cartilage repair at an articulating surface of a joint, including a medical implant and a set of tools. The medical implant includes a substantially plate shaped implant body having a predetermined cross-section that substantially corresponds to the area of the damaged cartilage. The set of tools includes a guide tool including a positioning body and a guide channel. The positioning body has a cartilage contact surface that has a shape and contour that is designed to correspond to and to fit the contour of the cartilage or subchondral bone in the joint in a predetermined area surrounding the site of diseased cartilage. The guide channel has a cross-sectional profile that is designed to correspond to the cross-section of the plate shaped implant body. Additional tools in the set of tools have a cross-sectional profile that is designed to correspond to the cross-sectional profile of the guide channel.
