1. A method of repairing a diseased or damaged knee joint of a patient, comprising:
- substantially matching a patient-specific surface of a tibial mold to at least a portion of a tibial spine of a tibia of the knee joint of the patient to align a guide in a predetermined orientation and position relative to the tibia, such that the guide defines a planar cutting or drilling path extending through at least a portion of the proximal end of the tibia along a predetermined path;
cutting or drilling tissue of the tibia along the planar cutting or drilling path to facilitate aligning a block for cutting a proximal portion of the tibia for subsequently placing an implant on the proximal portion of the tibia; and
placing the implant on the proximal portion of the tibia.

11. A method of repairing a diseased or damaged knee joint of a patient, comprising:
-
substantially matching first and second patient-specific surfaces of a tibial mold to at least portions of a tibia of the joint of the patient to align a guide in a predetermined orientation and position relative to the tibia, such that the guide defines a planar cutting or drilling path extending through at least a portion of the proximal end of the tibia along a predetermined path, wherein the first patient-specific surface has at least a portion that matches the geometry or shape of at least a portion of a surface of a tibial spine of the joint of the patient, and the second patient specific surface has at least a portion that matches the geometry of a cartilage surface of the tibia of the knee joint of the patient; cutting or drilling tissue of the tibia along the planar cutting or drilling path to facilitate the placement of an implant on a proximal portion of the tibia using a block, wherein the block includes a cut guide; and
placing the implant on the proximal portion of the tibia. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method of repairing a diseased or damaged knee joint of a patient, comprising:
-
substantially matching a patient-specific surface of a tibial mold to at least a portion of a tibial spine of a tibia of the joint of the patient to align a drill guide in a predetermined orientation and position relative to the tibia, such that the guide defines a drilling path extending through at least a portion of the proximal end of the tibia along a predetermined path; securing a cutting guide in a predetermined position relative to the drilling path; cutting or drilling tissue of the tibia along a path defined by the cutting guide to facilitate the placement of an implant on a proximal portion of the tibia using a tool introduced through the cutting guide; and placing the implant on the proximal portion of the tibia. - View Dependent Claims (20, 21, 22, 23, 24)

25. A method of repairing a diseased or damaged knee joint of a patient, comprising:
-
substantially matching first and second patient-specific surfaces of a tibial mold to at least portions of a tibia of the joint of the patient to align a drill guide in a predetermined orientation and position relative to the tibia, such that the drill guide defines a predetermined drilling path extending through at least a portion of the proximal end of the tibia, wherein the first patient-specific surface has at least a portion that matches the geometry of at least a portion of a surface of a tibial spine of the joint of the patient, and the second patient specific surface has at least a portion that matches the geometry of a cartilage surface of the tibia of the knee joint of the patient; securing a guide in a predetermined position relative to the drilling path to define a predetermined path; cutting or drilling tissue of the tibia along the predetermined path to facilitate the placement of an implant on a proximal portion of the tibia using a tool introduced through the guide; and placing the implant on the proximal portion of the tibia. - View Dependent Claims (26, 27, 28, 29, 30)
