1. A patient-specific surgical tool for use in surgically repairing a joint of a patient, comprising:
- a block having a patient-specific surface and first and second drilling holes;
the patient-specific surface having at least a portion that is substantially a negative of a corresponding portion of a diseased or damaged articular surface of the joint and having a predetermined position and orientation relative to the corresponding portion;
the first and second drilling holes having predetermined positions and orientations relative to the patient-specific surface and each having an axis that extends through a portion of the joint when the patient-specific surface is fit to the corresponding portion of the diseased of damaged articular surface of the joint.
