Knock knees is a condition in which the legs curve inward at the knees. When a child with knock knees stands, the knees appear to bend toward each other and the ankles are spread apart.

Knock knees most often develop as a part of normal growth. In some cases, especially if the child is 6 years of age or older, knock-knees may occur because of other medical problems such as injury of the shinbone, osteomyelitis (bone infection), overweight, and rickets.

The diagnosis of knock knees is made through a physical examination. In addition, X-rays may be taken if a child is older than 2 ½ years and has symmetrical legs.

Treatment for Knock Knees

Most children with knock knees do not require any treatment, but if the condition persists after age 7, then a night brace attached to an orthopaedic shoe may be recommended. If the separation between the ankles is severe, surgery may be an option.
