Knock knees

Specialty of Orthopaedic surgery

Genu valgum is the alteration of the mechanical axis of the knees, which creates a greater gap between the ankles when keeping the knees together. This is also known as knock knees. During a child's period of growth, there are some normal variations (physiological changes) and also various forces acting on the legs, so the genu valgum decrease with growth, meaning that the axis of legs in children between 7 and 8 years of age is normalised. After this period, surgical treatment is necessary to correct the axis.
