For a pedestrian impact, lower limb traumas induce knee joint injuries and bone fractures. These non lethal injuries lead to long period rehabilitation but also physical incapacities. In order to reduce these injuries (or their severity), the experimental and numerical research in the field of impact biomechanics aims to understand injury mechanisms and to define injury criteria. Hence, the virtual human body, once validated, provides data which cannot be recorded with experimental data. By using the advanced Lower Limb Model for Safety (LLMS), a knee joint injury criterion which correlated knee joint kinematics and ligament strain level until failure has been defined. These criterions, initially defined through isolated leg recruitments in lateral shearing or bending, were evaluated against real pedestrian impact conditions. If the previously defined injury mechanisms remain relevant, the results put emphasis on the need to introduce coupled effects between lateral shearing and bending in the definition of this injury criterion. Additionally, differences in impact position exhibit strong variation in injury mechanisms. These results provide bases of knee joint injury criteria which can be implemented for future regulation procedure in pedestrian car safety.
