Tibiofemoral kinematics and kinetics results during knee extension for different tibial slopes (reference, −3°, and +3° tibial slope). Tibiofemoral contact force during knee flexion (a). Femoral rollback (−) during knee flexion (b). Tibial internal (+) and external (−) rotation (c). Flexion facet centre (FFC) position of the medial (left) and lateral (right) femoral component relative to the tibial component (d) (+: increase of the tibial slope; −: decrease of the tibial slope).
