Patent ID: 8221430

Claim:
A method of manufacturing an arthroplasty jig, the method comprising: generating two-dimensional images of at least a portion of a bone forming a joint; using at least one computer processor to generate a first three-dimensional computer model of the at least a portion of the bone from the two-dimensional images; using at least one computer processor to generate a second three-dimensional computer model of the at least a portion of the bone from the two-dimensional images; causing the first and second three-dimensional computer models to have in common a reference position, wherein the reference position includes at least one of a location or an orientation relative to an origin; generating a first type of data with the first three-dimensional computer model, wherein the first three-dimensional computer model is a bone only model; generating a second type of data with the second three-dimensional computer model, wherein the second three-dimensional computer model is a bone and cartilage model; employing the reference position to integrate the first and second types of data into an integrated jig data; and using the integrated jig data at a manufacturing machine to manufacture the arthroplasty jig.
