Congenital dislocation of the knee (CDK) is characterized by hyperextension of the knee with forward displacement of the proximal tibia. It is associated with other joint dislocations and deformities and may occur isolated or as part of different systemic syndromes. Despite its characteristic postnatal morphology, prenatal descriptions are very scarce. We report a case of CDK diagnosed at 20 weeks, discuss its physiopathology, diagnosis and management and review the current literature.
先天性膝关节脱位（CDK）的特征是膝关节过伸，胫骨近端向前移位。它与其他关节脱位和畸形有关，可能单独发生，也可能是不同全身性综合征的一部分。尽管 CDK 具有典型的出生后形态，但产前描述非常罕见。我们报告了一例在 20 周时诊断出的 CDK，讨论了其病理生理学、诊断和管理，并回顾了当前的文献。
