Model
An adjusted model (3DGaitModel2392) with unrestricted degrees of freedom in the knee joint (angle, adduction, rotation, anterior-posterior, inferior-superior, medial-lateral), 10 ligaments and a tibiofemoral contact. The swing model is used to simulate a swing action, while the Lachman model is used to simulate the Lachman test where a force is applied to the posterior of the tibia in the direction of anterior-posterior displacement (no contact model for Lachman model).
