Claim One:
1. A surgical planning computerized method comprising: determining, using a computer programmed to perform the steps of the method, a predetermined number of control points for generating a predetermined number of areas representing cartilage, wherein the predetermined number of control points are associated with specified locations on a first implant component of a multiple-component implant; receiving measurements corresponding to a plurality of measured cartilage points, wherein each cartilage point is based on an associated control point from the predetermined number of control points; generating a plurality of areas representing cartilage, based on and in proximity to each cartilage point, wherein each area representing cartilage is associated with a control point, and wherein each area representing cartilage is larger than and projects to an associated control point from the predetermined number of control points; selecting a properly-sized multiple-component implant by computing a distance between two or more measured cartilage points and selecting a multiple-component implant having a distance between the two or more associated control points of the first implant that best matches the computed distance between the two or more cartilage points; positioning a representation of a first implant component of the properly-sized multiple-component implant by aligning the control points for the first implant with the associated measured cartilage points; automatically positioning a representation of a second implant component of the properly-sized multiple-component implant based on the position of the representation of the first implant component; and generating at least one virtual cutting boundary based on the position of the representation of a first implant component and the position of the representation of the second implant component, wherein the virtual cutting boundary is configured to provide perceptible feedback to guide a surgical tool during preparation of a bone to receive the first implant component and the second implant component.
