Bowlegs appear to be the opposite of knock-knees. Bowlegs are seen in most children at birth. Once a child starts crawling or walking, the condition may become more obvious. It is always worse from 12 to 18 months of age. Most children will outgrow this condition.
Parents often notice knock-knees when a child is standing.
In this condition the knees touch, but the ankles do not, when a child stands. Knock-knees are noticed in children often around age 3. Knock-knees are also common and are usually outgrown as the child matures. If your child has either of these problems, the child is likely to outgrow them without the need of special treatments. However, in severe cases, your healthcare provider may want the child to see a bone specialist for an evaluation of the knees and feet.
