title: Congenital dislocation of the knee reduced spontaneously or with minimal treatment.
abstract: Six cases of congenital dislocation of the knee (CDK) reduced spontaneously or with minimal treatment were investigated. Reduction was achieved from 4 days to 3 months after birth. Clinical results were good, although in four cases, hyperextension < or = 20 degrees persisted. In view of the perinatal complications and associated anomalies, CDK reduced with no or minimal treatment is supposed to be a category of congenital postural deformity. We believe that it is advisable to wait 1 month for spontaneous reduction of CDK in cases not associated with clubfoot, arthrogryposis multiplex congenita, and Larsen's syndrome.
