1. A surgical system including an articular repair system and a patient-specific surgical tool for use in surgically repairing a joint of a patient, wherein the patient-specific surgical tool comprises:
- a block having a patient-specific surface and first and second guides;
the patient-specific surface having at least a portion that is substantially a negative of a corresponding portion of a diseased or damaged cartilage surface of the joint of the patient;
the first and second guides having predetermined positions and orientations relative to the patient-specific surface and being oriented to provide two predetermined drilling or cutting paths that are aligned relative to a biomechanical or anatomical axis of the joint and through a portion of the joint of the patient when the patient-specific surface is placed against the corresponding diseased or damaged cartilage surface of the joint of the patient.
