Blount Disease


Blount disease is a growth disorder in children and adolescents characterized by a pathologic varus bowing (unilateral or bilateral) of the knees. The disease typically occurs in obese patients, and appears at two stages of life: infancy and adolescence. Treatment depends on the age of the patient and the severity of the deformity. In infantile Blount disease, a trial of bracing may be beneficial in children younger than 3 years. If there is no improvement and the disease progresses radiographically, surgical correction should be performed. In adolescent Blount disease, a progression of the deformity is likely if left untreated. Medial joint line pain is likely to worsen, and the altered forces within the joint can lead to early degenerative disease. Surgical intervention aimed at realigning the mechanical axis to potentially allow for normal medial physeal growth is therefore recommended.
