Claims80
A method of making a surgical tool, the method comprising:
- obtaining images data associated with at least a portion of a joint;
- and
- deriving a substantially uncut cartilage surface associated with the joint from the image data;
- and
- providing a surgical tool that includes a contact surface for engaging the substantially uncut cartilage surface associated with the joint, the surgical tool further including at least one guide for directing movement of a surgical instrument in preparing an implant site, wherein providing the surgical tool includes:
- shaping the contact surface based on the derived cartilage surface such that the contact surface conforms to and is substantially a negative of the derived cartilage surface;
- and
- determining position, shape and/or orientation of the at least one guide from the image data, so that changes induced on the implant site by the surgical instrument ensures a desired orientation of an implant.

A method of making a patient specific surgical tool for engaging a surface of a patella, the method comprising:
- obtaining image data associated with at least a portion of the patella;
- and
- deriving a substantially uncut cartilage surface associated with the patella from the image data;
- and
- providing a surgical tool that includes a contact surface for engaging the substantially uncut cartilage surface associated with the patella, the surgical tool further including at least one guide for directing movement of a surgical instrument in preparing an implant site, wherein providing the surgical tool includes:
- shaping the contact surface based on the derived cartilage surface such that the contact surface conforms to and is substantially a negative of the derived cartilage surface;
- and
- determining position, shape and/or orientation of the at least one guide from the image data, so that changes induced on the implant site by the surgical instrument ensures a desired orientation of an implant.
