Knock knees

Alternative Names:

Genu valgum

Treatment:

Knock knees are usually not treated. Surgery may be considered for knock knees that persist beyond late childhood and in which the separation between the ankles is severe.

Expectations (prognosis):

Children normally outgrow knock knees without treatment, unless there is an underlying disease. For cases requiring surgery, the procedure provides excellent cosmetic results.

Complications:

Difficulty walking (very rare)
Self-esteem changes related to cosmetic appearance of knock knees
If left untreated, knock knees can lead to early arthritis of the knee

Calling your health care provider:

Call your health care provider to schedule an evaluation if you suspect your child has knock knees.
