Hello, Genu valgum, commonly called "knock-knee", is a condition in which the knees angle in and touch one another when the legs are straightened. In most cases, knock knees don't need to be treated because the problem tends to correct itself as a child grows.But you're 21 year old adult, ends of bone have fused already ,now you cannot realign the bones just by exercise ,you need surgery.
