Abstract:
1. A method for positioning a prosthetic component on a three-dimensional model of a limb with respect to a mechanical axis of the limb, the method comprising: gathering patient-specific anatomical data of said limb; identifying first, second, and third anatomical landmarks based on the patient-specific anatomical data; determining a first spatial relationship based at least on the first and second anatomical landmarks; determining the mechanical axis of the limb based at least on the first spatial relationship and the third landmark; determining a first positioning of the prosthetic component such that the prosthetic component has a predetermined orientation with respect to the determined mechanical axis; identifying a fourth anatomical landmark based on the patient-specific anatomical data; and based on the fourth anatomical landmark and the first positioning of the prosthetic component, determining a second positioning of the prosthetic component that maintains the predetermined orientation with respect to the determined mechanical axis and limits an additional degree of freedom of the prosthetic component.
