Abstract

The biomechanical models are evolving in order to be as close as possible to the clinic. Quantified movement analysis offers predictive and / or functional methods that help determine and model functional axes known as helical axes that seem today to represent the means closest to human joint movement. The knee is a joint with complex movements subject to kinematic modifications. The knee joint changes that occur during life seem to modify the helical axes and disrupt the kinematics of the joint. These alterations cause joint replacements by total knee arthroplasty which have the particularity of being based on the knee axes in order to restore the anterior kinematics of the knee with the aim of early functional recovery. The current design of total knee prostheses makes it possible to partially restore the functional axes of the knee, which could in the long-term cause biomechanical disturbances responsible for sometimes unsatisfactory results.
