The treatment of genu valgum in children depends on the underlying cause. Developmental also known as idiopathic genu valgum is usually self-limiting and resolves during childhood. Genu valgum secondary to nutritional rickets is typically treated with life style modifications in the form of adequate sun exposure to ensure receiving the daily requirements of vitamin D and nutrition with rich calcium diet. Additionally calcium and vitamin D supplementations may be used. If the deformity does not resolve despite the above conservative treatment and the deformity is severe and causing gait impairment, then surgery can be an option. Typically, guided growth surgery is used to straighten the deformed bone. Genu valgum arising from osteochondrodysplasia usually needs repeated guided growth surgical interventions. Genu valgum secondary to trauma depends on the degree of physeal damage. And usually limb reconstruction procedures are needed, especially if trauma occurs in the early years of life where the anticipated remaining longitudinal bone growth is great.
