Tibiofemoral kinematics and kinetics results during knee flexion for different tibial component rotations (reference, 3°, and 6° internal/external rotation). 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) (int: internal rotation; ext: external rotation).
