1. A method of manufacturing a patient-specific surgical tool for use in surgically repairing a diseased or damaged joint of a patient, comprising:
- designing a patient-specific surface that substantially conforms to at least a portion of an articular cartilage surface of the joint, wherein the patient-specific surface is derived from information regarding articular cartilage of the joint and is further derived from information regarding subchondral bone of the joint; and
orienting a guide to define a cutting or drilling path having a predetermined position and orientation relative to the patient-specific surface and extending through at least a portion of the tissue of the joint when the patient-specific surface is aligned with and placed against the corresponding portion of the articular cartilage surface of the joint.

Abstract
Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

30. A method of manufacturing a patient-specific surgical tool for use in surgically repairing a diseased or damaged joint of a patient, comprising:
-
designing, based on image data of the joint of the patient, a patient-specific surface that approximates, in at least a portion, an articular cartilage surface of the joint, wherein the articular cartilage surface is approximated using at least in part information about a subchondral bone surface of the joint derived from the image data and cartilage information based, at least in part, on data of the patient; orienting a guide to define a cutting or drilling path having a predetermined position and orientation relative to the patient-specific surface and extending through at least a portion of tissue of the joint when the patient-specific surface is aligned with and placed against the corresponding portion of the surface of the joint.
