Blount disease (MONDO_0017194) is characterized by disturbed growth of the inner portion of the upper tibial extremity, progressively leading to bowlegged deformity with bone angulation just below the knee (tibia varus). In 60% of cases, the condition affects both legs. Also known as: Blount's disease, Osteochondrosis deformans tibiae, familial infantile type osteochondrosis deformans tibiae, infantile tibia vara, tibia vara Blount.
