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.

The default starting items are fine on Varus.

Deformity of the elbow, in medical terms called " Cubitus varus" , or forearm being angulated towards the midline of the body rather than angled slightly outside is "Gun stock" deformity. It is often result of badly united fracture of the lower end of the bone uf the upper arm, Humerus. It can be treated by surgery. Some cosmatic problem of minor nature may persist even after surgery.
