Generalities:

The name of Genu Valgum derives from the Latin Genu = knee and Valgo = approach; that is, approaching the knees. The opposite is the Genu varo: away from the knees or "zambo". In the stages of growth the knees have to form different angles, the babies that just walk present in genu varo. Children and especially girls tend to present genu valgo. When the bone structure has just been formed regularly, the normal "Q" angle of about 5 ° is reached.
