Biomechanical modelling of knee joint for assisting high tibial osteotomy

A biomechanical model of the lower limb with active three-dimensional (3D) muscles is developed in the open-source Artisynth platform (www.artisynth.org) to simulate knee movement. This model is going to be used in particular to broaden our knowledge about the biomechanical effects of high tibial osteotomy surgery and to assist the surgical planning procedure. The model geometry has been reconstructed from MRI and CT data of a reference subject. The joint movement is acquired by activating various muscle groups. The joint kinematics as well as contact pressure distribution is monitored.
