Abstract
A joint alignment method comprises using imaging data of at least a portion of a leg to create a leg model, wherein the leg model includes a femur having medial and lateral condyles and a tibia having tibial plateaus that are configured to engage the medial and lateral condyles at a knee joint, displaying an image of the leg model for manipulation by a user, locating a pivot point within one of the medial or lateral condyles, and rotating, in the displayed image, the tibia with respect to the femur, about the pivot point, to obtain a desired knee joint articulation in a specified plane.
