Also known as: genu valgum
What are knock knees?
When a child’s legs are bent inward at the knee (the opposite of bowlegs), this condition is known as knock knees, or genu valgum.
What causes knock knees?
The precise cause of knock knees is not always clear. Often, children will develop some degree of knock knees during the first 3-4 years of growth as part of normal growth and development. This form of knock knees will often go away spontaneously. Others may develop it as part of another bone disease, as a result of an injury or infection, or for other reasons.
What are the symptoms of knock knees?
Other than the physical symptoms of the knees touching while the ankles do not, other signs of knock knees include difficulty walking or an unusual walking pattern. Pain is a rare symptom of knock knees in children and adolescents.
What are knock knees care options?
Some cases of knock knees resolve on their own and observation for several years may be indicated, especially in young children. Other cases may require a small outpatient surgery to modulate growth, and some cases may require more extensive surgery to realign the bone.

A group of children in Algeria who underwent complex surgeries as part of a 2016 U.S.-sponsored medical mission have many reasons to celebrate, and can do so with better movement of their limbs.
Caludell noticed that 6 of her 11 children had belly buttons that stuck out, and they seemed to become more pronounced around the time they entered kindergarten. When her daughters started to become self-concious about how their belly buttons looked, Claudell was able to schedule all 6 umbilical repair surgeries on the same day at the Miami Children's Ambulatory Surgery Center.
