What is another term for bow legged?

Answer 1

This would be termed genu varum or a varus deformity of the knees. Varus is the term given when the distal part of a joint is angled toward from the midline. In this case the tibia, the large bone in the lower leg, is angled toward the midline in relation to the femur (with the knee joint being the one in question).

The opposite of this, a knock-kneed appearance is termed genu valgum or a valgus deformity.
