Claim:
1. A method comprising: obtaining patient-specific anatomical data of a limb; identifying a plurality of anatomical landmarks of the limb using the patient-specific anatomical data; performing a series of computations to determine a three-dimensional mechanical axis of the limb based on the identified plurality of anatomical landmarks; determining one or more planes for bone cuts on the limb based on the identified plurality of landmarks and the determined three-dimensional mechanical axis of the limb, at least one of the one or more planes having a predetermined orientation with respect to the determined three-dimensional mechanical axis of the limb; and manufacturing a patient-specific surgical item based at least partially on the determined three-dimensional mechanical axis of the limb, the patient-specific surgical item including a portion that conforms to a corresponding portion of a bony surface of the limb such that the patient-specific surgical item is configured to engage the limb in a predetermined orientation, and the patient-specific surgical item is configured to indicate the determined one or more planes with respect to the limb when the patient-specific surgical item is engaged with the limb in the predetermined orientation.
