1. A method for identifying and characterizing a problem of a knee joint, the method comprising: receiving biomechanical data from sensors, the biomechanical data being representative of a movement of the knee joint; generating a biomechanical profile based on the biomechanical data; 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.
