Knock knees, also called genu valgum, is a condition in which the legs curve inward at the knees. When a child 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.
Diagnosis of Knock Knees
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.
