Congenital dislocation of the knee (CDK), is commonly referred with a variety of names, mainly genum recurvatum of knee, backward bending of the knee, hyperextension of the knee, dislocation of the knee, and recently as developmental dysplasia and dislocation of the knees [1]. Whichever name is used, the typical clinical features in an infant is an abnormal anterior hyperextensive position of either one or both knees noted at birth [1,2].
