1. A method of generating a kinematic model of a patient'"'"'s joint using a computer system, the method comprising:
- obtaining from a first source electronic image data of the patient'"'"'s joint that includes both normal and diseased tissue, the data comprising at least one of volume, area, thickness, shape, curvature, geometry, biochemical contents, signal intensity and relaxation time of said normal and/or diseased tissue;
obtaining from a second source electronic biomechanical data derived from the patient, wherein the biomechanical data comprises data concerning relative motion of the joint; and
generating from the image data and biomechanical data an electronic kinematic model of the patient'"'"'s joint.

Abstract
Methods are disclosed for assessing the condition of a cartilage in a joint, particularly a human knee. The methods include converting an image such as an MRI to a three dimensional map of the cartilage. The cartilage map can be correlated to a movement pattern of the joint to assess the affect of movement on cartilage wear. Changes in the thickness of cartilage over time can be determined so that therapies can be provided. Information on thickness of cartilage and curvature of cartilage or subchondral bone can be used to plan therapy. Information on movement pattern can be used to plan therapy.

19. A method of generating a kinematic model of a patient'"'"'s joint using a computer system, the method comprising:
-
obtaining from a first source electronic image data of a joint that includes information comprising at least one of volume, area, thickness, shape, curvature, geometry, biochemical contents, signal intensity and relaxation time of normal and/or diseased tissue; obtaining from a second source biomechanical data associated with the joint; and creating an electronic kinematic model of the joint based on the image data and on the biomechanical data, wherein the model includes a contact area between two components of the joint. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
