The present document describes an apparatus and method for identifying and characterizing a problem of a knee joint. In accordance with an embodiment, the method comprises receiving biomechanical data from sensors and generating a biomechanical profile based on the biomechanical data, the biomechanical data being representative of a movement of the knee joint. The method also involves, in a processing device, classifying the biomechanical profile of the knee joint in one of multiple classes of knee joint problems by applying a pattern recognition technique to a normative biomechanical profile associated to the one of the multiple classes, each one of the multiple classes corresponding to at least one knee joint problem; based on the classifying, identifying the problem as comprising the at least one knee joint problem of the one of the multiple classes; and archiving the problem identified in a storing device to make the problem accessible during consultation.

Method and system for knee joint evaluation and diagnostic aid in normal and pathologic state

A method for creating a frame of reference of a leg of a subject for subsequent 3-D kinematic analysis of the leg with non-invasive trackable references secured to the femur and the tibia of the leg. The method comprises the steps of: i) obtaining tibial and femoral axes with respect to the trackable references by tracking points and motions of the leg; ii) registering a known posture of the subject with respect to the trackable references; iii) obtaining a desired posture of the subject with respect to the trackable references as a function of the known posture by tracking a predetermined motion of the leg; and iv) setting a frame of reference to said tibial and femoral axes of the leg in the desired posture of the subject with respect to the trackable references.

Method of calibration for the representation of knee kinematics and harness for use therewith

A harness for attachment about a knee femur and comprised of a rigid and non-flexible frame support two resiliently mounted clamping means and sensors is described for the non-invasive measurement of knee motion and its analysis in 3-D is described. The clamping means elements are urged under pressure outwardly for application against a skin outer surface at predetermined medial and lateral sites relative to a femur. A non-resilient adjustable stabilizing element is connected to the rigid frame and disposed at a predetermined location with respect to the medial clamping element in spaced relationship therewith and adjustable for clamping contact on a skin outer surface and in alignment with the center of a medial condyle of the femur whereby to stabilize the rigid frame about a knee. An attachment rod is secured to the harness and has straps for securing the rod above the knee.
