The method may further include employing the model in defining manufacturing instructions for the manufacture of a customized arthroplasty jig. A customized arthroplasty jig may be manufactured according to the above-described method and is configured to facilitate a prosthetic implant restoring a patient joint to a natural alignment.

System and method for image segmentation, bone model generation and modification, and surgical planning

A computer-implemented method of preoperatively planning a surgical procedure on a knee of a patient including determining femoral condyle vectors and tibial plateau vectors based on image data of the knee, the femoral condyle vectors and the tibial plateau vectors corresponding to motion vectors of the femoral condyles and the tibial plateau as they move relative to each other. The method may also include modifying a bone model representative of at least one of the femur and the tibia into a modified bone model based on the femoral condyle vectors and the tibial plateau vectors. And the method may further include determining coordinate locations for a resection of the modified bone model.
