Valgus knee (Knock knees)
Knock-knees is a condition where the knees angle in and touch one another when the legs
are straightened. Females have a wider pelvis than men and a relatively shorter length
of the thigh bone, and as a result, have a greater static genu valgum than men.
Individuals with severe valgus deformities are typically unable to touch their feet
together while simultaneously straightening the legs.
Mild knock knees can be seen in children from ages 2 to 5, and is often corrected
naturally as children grow. However, the condition may continue or worsen with age,
particularly when it is the result of a disease, such as rickets or obesity.
