The rotation results because the lateral condyle of the femur is slightly smaller than the medial condyle. Thus the lateral condyle finishes its rolling motion first followed by the medial condyle. The resulting small medial rotation of the femur serves to lock the knee.

Rotation can occur within the vertebral column at a pivot joint or at a ball-and-socket joint. Rotation of the neck or body is the twisting movement produced by the summation of the small rotational movements available between adjacent vertebrae. At a pivot joint one bone rotates in.

Pronation is when the foot rolls inward about 15 when weight is placed on it. If you are just standing still the foot will roll inward and the arch will flatten out - this is pronation. This shows grade level based on the words complexity.
