The present invention provides a design method designing an implant specific drill bit comprising steps; e. determining or selecting a size and shape of an orthopedic implant comprising a circular shaped implant body and a centrally placed circular shaped extending post protruding from the bone contacting surface in a longitudinal y-axis direction of the implant; and f. selecting design parameters for the implant specific drill bit by; - selecting the width of the broadest part of the bone remover in a side view to correspond to, or to be slightly smaller than, the diameter of the implant body of the specific implant that is to be implanted; - selecting the rotational volume and the length of the central drill part to correspond to, or to be slightly smaller than, the diameter of the extending post of the specific implant that is to be implanted; -selecting the curvature of the cutting edge that is placed anywhere peripherally around or surrounding the central drill part of the implant specific drill bit to correspond to the curvature of the bone contacting surface of the implant.

This invention relates to a surgical instrument, a guide tool for cartilage repair at an articulating surface of a joint, and also to the design method of the guide tool. More specifically the invention concerns a method of designing a guide tool for cartilage repair in an articulating surface of a joint, comprising the steps of: VI. determining physical parameters for cartilage damage in a joint and generating design parameters for cartilage repair objects and their relative placement in a predetermined pattern, comprising: VII. selecting repair objects to fit the individual cartilage damage site wherein the repair objects have; - surfaces intended to align with the articular cartilage surface in the joint, based on the healthy surface contour curvature VIII. determining, based on obtained image data, positions and angles of the selected cartilage repair objects, wherein the positions and angles are adapted so that the selected repair objects fit the individual cartilage damage site IX. generating design parameters of the guide tool, for placement of the cartilage repair objects comprising the following steps; generating the design for an upper part and a lower part of a guide channel in a guide body extending from the positioning body, said guide channel passing through said positioning body and said guide body wherein the angles and positions are generated dependent on and substantially corresponding to the determined angles and positions of the selected cartilage repair objects, and wherein; the design for the lower part of all the guide channel is generated dependent on and substantially corresponding to the determined cross sectional areas, of the selected cartilage repair objects.
