Abstract:
1. A method of manufacturing a patient specific arthroplasty jig, the method comprising: providing a near-shape jig blank to a manufacturing machine, the near-shape jig blank having a first outer surface having a pair of generally orthogonal surfaces, a second outer surface opposite the first outer surface, and a feature that will be retained in the patient specific arthroplasty jig, the feature including a general shape of the near-shape jig blank, the general shape being specific to either a right knee or a left knee; using the manufacturing machine to create the patient specific arthroplasty jig from the near-shape jig blank by generating in the first outer surface of the near-shape jig blank patient specific features including a matching surface corresponding to an articular surface of a knee of a patient, the matching surface being generated preoperatively using a computer and determined from a preoperative analysis of image data of the articular surface of the knee of the patient, the matching surface being configured to mechanically register to the articular surface; and using the manufacturing machine to generate in the near-shaped jig blank a saw guiding slot, the saw guiding slot being generated preoperatively.
