Blount disease is an acquired, asymmetrical disorder of proximal tibial growth that results in a complex three-dimensional proximal tibial deformity, with tibial varus being the dominating feature. Although the exact pathophysiology is unknown, Blount disease is separated into 2 clinical variants, infantile and adolescent, based on the onset of symptoms occurring before or after the age of 10 years. If recognized and treated early, affected patients generally have a favorable prognosis; however, if neglected, it can lead to progressive malalignment and premature osteoarthritis. We present a patient with bilateral neglected Blount disease who underwent successful bilateral total knee arthroplasty performed in a staged fashion using a gap balancing technique with constrained condylar knee implants.
布朗特病是一种后天获得性的、不对称的胫骨近端生长紊乱疾病，会导致复杂的三维胫骨近端畸形，其中胫骨内翻是主要特征。尽管确切的病理生理学尚不清楚，但根据症状出现于10岁之前或之后，布朗特病可分为两种临床类型，即婴儿型和青少年型。如果能早期识别并治疗，受影响的患者通常预后良好；然而，如果被忽视，它会导致进行性畸形和过早出现骨关节炎。我们报告一例双侧被忽视的布朗特病患者，该患者采用带限制髁膝关节假体的间隙平衡技术，分阶段成功进行了双侧全膝关节置换术。
