1. A system for determining an accuracy of a bone model, the system comprising:
at least one processor; and
at least one memory having a plurality of instructions stored thereon that, in response to execution by the at least one processor, causes the system to:
determine a landmark based on a user's selection of a point in a three-dimensional volume image of a patient's joint via a graphical interface,
identify a plane of the three-dimensional volume image that intersects the landmark by including the point,
process the three-dimensional volume image to determine a border curve defined by an intersection of the plane and a three-dimensional surface model of a portion of the patient's joint, wherein the intersection divides the three-dimensional surface model into a first half surface and a second half surface, and
generate an integrated image for displaying on the graphical interface, wherein the integrated image includes at least a portion of the three-dimensional volume image, and wherein only the first half surface of the three-dimensional surface model and the integrated image identifies the border curve.
