摘要： A method of designing a guide tool for cartilage repair in an articulating surface of a joint, comprising the steps of: I. 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: II. selecting repair objects to fit the individual cartilage damage site wherein the repair objects have: cross sectional areas adapted to fit the surface area of the cartilage damage site, lengths adapted to fit the selected joint and/or type of cartilage damage, and surfaces intended to align with the articular cartilage surface in the joint, based on the healthy surface contour curvature, III. 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, IV. generating design parameters of the guide tool, for placement of the cartilage repair objects comprising the following steps of: 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.
