Some children develop a rare growth disorder called Blount’s disease. This disorder causes their legs to bow just below the knees. The bowing can cause pain and discomfort in some children. Many infants and toddlers show bowing early in life, but their legs begin to straighten as they start to walk. In the case of Blount’s disease, the lower legs will not straighten, or they begin to bow further. Physicians can treat Blount’s disease in children, though the disorder may require special braces or surgery.


1. Symptoms

The main symptom of Blount’s disease is the signature bowing of the legs that occurs just below the knee. The disorder is also rapidly progressive and can worsen quickly. As the disease progresses, the affected child may feel pain or discomfort, and experience difficulty walking. The bowing may be present in one or both legs, depending on the manifestation of the disease. Infants and adolescents have similar but different symptoms, leading to physicians splitting Blount’s disease into two classifications.
