Abstract
Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient'"'"'s joint. The data can be used to create a model for analyzing a patient'"'"'s joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

11. A method for minimizing resected bone from a single patient in need of an articular implant replacement procedure, the method comprising:
- (a) identifying unwanted tissue from one or more images of the patient'"'"'s joint;
(b) identifying a combination of resection cuts and implant component features that remove the unwanted tissue and also provide maximum bone preservation; and
(c) selecting and/or designing for the patient a combination of resection cuts and implant component features that provide removal of the unwanted tissue and maximum bone preservation. - View Dependent Claims (13, 14, 15, 17, 18, 19, 20, 21, 22)
