1. A surgical planning method comprising:

  • capturing data as a native joint is moved within a range of motion of the joint using a tracking system associated with a computing system, the joint comprising a first bone and a second bone;

    using the computing system to perform the steps of;

    representing the first bone of the joint;

    associating a first implant model with the representation of the first bone;

    representing a second bone of the joint;

    based on the captured data, determining, at a plurality of flexion angles within the range of motion of the joint, a distance from at least one point on a surface of the first implant model to at least one of;

    (1) at least one point on a surface of the representation of the second bone or (2) at least one point on a surface of a second implant model associated with the representation of the second bone; and

    displaying information representative of the determined distances at the plurality of flexion angles in a graphical representation indicating at least one of the plurality of flexion angles and the determined distance for the at least one of the plurality of flexion angles.
