Knock knees in children: causes, symptoms, treatment

Knock knees, or genu valgum, is a common condition in children where knees touch but feet are apart.

For most young children, knock knees are a normal growth stage that typically self-corrects by age seven or eight.

Vitamin D deficiency causing rickets is a known cause of knock knees in children.

Children who are overweight may have more pronounced knock knees due to increased thigh girth.

Occasionally, knock knees can result from injury near the knee or bone disorders.
