1. A method of using a patient-matched surgical instrument to implant an orthopedic implant in a patient, comprising:
- placing a patient-specific surface of the patient-matched surgical instrument against a corresponding surface portion of or near a joint of the patient such that the patient-specific surface is substantially entirely engaged against the corresponding surface portion of the patient;
cutting or drilling a portion of the tissue in or near the joint of the patient using a guide of or attached to the patient matched surgical instrument; and
implanting the implant in or near the joint based at least in part on the location of the cut or drilled portion;
wherein the patient-specific surface is derived from first image data of at least a portion of the joint; and
wherein the guide has a predetermined alignment relative to the patient-specific surface derived at least in part from second image data of at least a portion of a second joint, wherein the second image data includes three-dimensional image data.

15. A method of using a patient-matched surgical instrument to implant an orthopedic implant in a patient, comprising:
-
placing a patient-specific surface of the patient-matched surgical instrument against a corresponding surface portion of or near a joint of the patient such that the patient-specific surface is engaged against the corresponding surface portion of the patient in a predetermined position; cutting or drilling a portion of the tissue in or near the joint of the patient using a guide of or attached to the patient matched surgical instrument; and implanting the implant in or near the joint based at least in part on the location of the cut or drilled portion; wherein the patient-specific surface is derived from magnetic resonance image data of at least a portion of the joint; and wherein the guide has a predetermined alignment relative to the patient-specific surface, wherein the predetermined alignment is derived at least in part from second image data of at least a portion of a second joint, wherein the second image data includes three-dimensional image data. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of using a patient-matched surgical instrument to implant an orthopedic implant in a patient, comprising:
-
placing a patient-specific surface of the patient-matched surgical instrument against a corresponding cartilage surface portion of a joint of the patient such that the patient-specific surface is engaged against the corresponding cartilage surface in a predetermined position; cutting or drilling a portion of the tissue in or near the joint of the patient using a guide of or attached to the patient matched surgical instrument; and implanting the implant in or near the joint based at least in part on the location of the cut or drilled portion; wherein the patient-specific surface is derived from computed tomographic image data of at least a portion of the joint; and wherein the guide has a predetermined alignment relative to the patient-specific surface, wherein the predetermined alignment is derived at least in part from second image data of at least a portion of a second joint, wherein the second image data includes three-dimensional image data. - View Dependent Claims (27, 28)

29. A method of using a patient-matched surgical instrument to implant an orthopedic implant in a patient, comprising:
-
placing a patient-specific surface of the patient-matched surgical instrument against a corresponding articular surface portion of or near a joint of the patient such that the patient-specific surface is engaged against the corresponding articular surface portion of the patient in a predetermined position; cutting or drilling a portion of the tissue in or near the joint of the patient using a guide of or attached to the patient matched surgical instrument; and implanting the implant in or near the joint based at least in part on the location of the cut or drilled portion; wherein the patient-specific surface is derived from image data of the corresponding articular surface portion of the joint; and wherein the guide has a predetermined alignment relative to the patient-specific surface derived at least in part from alignment information associated with a second joint. - View Dependent Claims (30)
