The tibia and femur are curved outwards and if the limbs are extended
although the ankles are in contact then there is a distinct space between
the knee joints. During the first year of life a gradual change take place
and the knee joints approach one another and the femur slopes
downward and inward towards the knee joints.
The tibia becomes straight and the sole of the foot faces almost directly
downwards. Now while these changes are occurring the bones which at
first consist principally of cartilage are gradually becoming ossified. By
the time a normal child begins to walk the lower limbs are prepared both
by their general direction and by the rigidity of the bones which form
them to support the weight of the body.
