Soft tissues loadings on healthy knee at different physiological flexions: a coupled experimental-numerical approach

Résumé

Knee degradation and pain when developing osteoarthritis are strongly related not only to the pressure on the cartilage, but also to the knee stability and to the subsequent loadings on the ligaments. Authors proposed the knee models without any flexion [1][2]. Knee flexion had been introduced by controlling actively muscular groups [3] or by using a full displacement-controlled model [4]. But in both cases, the pressure applied on the articulation has been questioned, the forces used to achieve the flexion being far from the physiology in the former and the bone positioning uncertainties leading to high variations in the cartilage pressure and ligament loads in the latter. Here, we propose a mixed approach, both using medical imaging (MRI, EOS X-ray system [5]) and force platform in conjunction with a finite element model.
