Bowlegs is a condition in which a person’s legs appear bowed out, meaning their knees stay wide apart even when their ankles are together. Bowlegs is also known as congenital genu varum. Bowlegs can sometimes be a sign of an underlying disease, such as Blount’s disease or rickets, and may lead to arthritis in the knees and hips. Treatment options include braces, casts, or surgery to correct these bone abnormalities. This condition is fairly common in infants because of their cramped position in the womb.
