True regarding knee movements are all except
During last stages of extension, femur rotates medially on tibia due to quadriceps femoris to lock the knee joint. Femur rotates laterally on tibia during flexion. 
In lateral and medial tibio femoral compartments there is a differential motion, where lateral compartment shows a higher relative motion than the medial. The anterior horns move more than the posterior.
Flexion is coupled with lateral rotation
Differential motion in lateral & medial compartments
Posterior horn of menisci move more than anterior
In full extension collateral ligaments are taut
