Claims17
A method for making a patient specific surgical tool based at least in part on a joint space width in a joint of a patient, the method comprising:
- obtaining image data associated with at least a portion of the joint of the patient;
- determining the joint space width of the joint based at least in part on the image data;
- determining at least one of a mechanical and an anatomical axis associated with the joint;
- generating a patient-specific surgical tool based in part on the joint space width;
- wherein the surgical tool includes at least one surface portion having a shape that substantially conforms to a corresponding surface portion of the joint of the patient, and includes a surgical instrument guide having a predetermined position relative to the surface portion such that the surgical instrument guide defines a predetermined cutting or drilling path relative to the at least one of the mechanical and the anatomical axis of the joint when the surface portion is aligned with and placed against the corresponding surface portion of the joint, so as to provide a desired postoperative correction.
