A method of manufacturing a surgical kit for cartilage repair in an articulating surface of a joint, comprising the steps of receiving radiology image data representing three dimensional image of a joint； generating a first three dimensional representation (330,460) of a first surface of the joint (260) in a trainable image segmentation process dependent on a trained segmentation process control parameter set (420) and said radiology image data； generating a set of data representing a geometrical object based on said first surface, wherein said geometrical object is confined by said first surface； generating control software adapted to control a CAD or CAM system to manufacture a surgical kit for cartilage repair dependent on said set of data representing a geometrical object and on a predetermined model of components of said surgical kit.
