In children with bilateral Blount’s Disease, the vast majority of patients present with deformity of both legs concomitantly at the time of initial diagnosis. Although the severity of deformity may not be identical in each limb, it is generally present to some degree on both sides. Asynchronous presentation of bilateral Blount’s Disease has been reported in the Japanese literature8, but to our knowledge there are no reports of such a presentation in the English literature. We report this case due to its apparent rarity, and also as a reminder to maintain vigilance for the possible late development of contralateral deformity in patients with presumed unilateral tibia vara.
