Abstract: A knee replacement system, and a method for supplying and implanting a knee replacement system, for enabling natural knee movement in a leg in a patient, including: a medial femoral component having a medial femoral articulating surface with a sagittal plane profile including four medial femoral arcuate portions scaled by a first femoral scaling factor; a lateral femoral component having a lateral femoral articulating surface with a sagittal plane profile including four lateral femoral arcuate portions sealed by a second femoral scaling factor; a medial tibial component having a medial tibial articulating surface that articulates with the medial femoral articulating surface and includes a first raised medial edge that increases in width in an anterior direction; and a lateral tibial component having a lateral tibial articulating surface that articulates with the lateral femoral articulating surface and includes a second raised medial edge that increases in width in the anterior direction.

Abstract: The therapeutic system of the preferred embodiments includes a foot platform having a lateral segment and a medial segment. The foot platform is coupled to the foot of the patient and supports the body force of the patient. The foot platform functions to move the foot from an equilibrium position to an activated position. The transition of the foot between equilibrium position and activated position, preferably occurs substantially instantaneously once the foot platform supports greater than substantially half of the body force.

Abstract: The present invention provides systems and methods that measure and analyze a user's movement during a specific activity, then provide immediate, focused feedback as to how the user can modify the movement.

Abstract: A markerless motion capture system is provided for measurements accurate enough for biomechanical, clinical, sport, entertainment, animation, game and movie, design, ergonomics, surveillance applications. The system has multiple cameras distributed around a viewing volume. The cameras allow for the creation of three-dimensional mesh representations of an object dynamically moving within the viewing volume. A model of the object that incorporates specific morphological and kinematic model information (including soft joint constraints) is then matched to the captured three-dimensional mesh representations. The matching routine aims to embed the model into each of the three-dimensional representations using (i) iterative closest point or simulated annealing algorithms and (ii) using soft joint constraints. This unique combination of routines offers a simple, time-efficient, accurate and thus more meaningful assessment of movements.

Abstract: Methods are disclosed for assessing the condition of a cartilage in a joint, particularly in 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 o 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.

Abstract: Methods are disclosed for assessing the condition of a cartilage in a joint and assessing cartilage loss, particularly in 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. The amount of cartilage tissue that has been lost, for example as a result of arthritis, can be estimated.

Abstract: A femoral component for a prosthetic knee implant system. The femoral component comprises medial and lateral condyles, wherein the height of the medial condyle is greater than the height of the lateral condyle.
