In conclusion the Flexion / Extension movement of the knee is not a fixed hinge type system but rather a dynamic role- and glide- mechanism with an endrotation in full extension. Flexion and
extension is performed along several axes with dynamic centers of rotation secured statically by changing combinations of
ligaments and dynamically by groups/combinations of muscels.
