CONGENITAL DISLOCATION OF THE KNEE REDUCED SPONTANEOUSLY OR WITH MINIMAL TREATMENT

Six cases of congenital dislocation of the knee (CDK) reduced spontane ously or with minimal treatment were investigated. Reduction was achie ved from 4 days to 3 months after birth. Clinical results were good, a lthough in four cases, hyperextension less than or equal to 20 degrees persisted. In view of the perinatal complications and associated anom alies, CDK reduced with no or minimal treatment is supposed to be a ca tegory of congenital postural deformity. We believe that it is advisab le to wait 1 month for spontaneous reduction of CDK in cases not assoc iated with clubfoot, arthrogryposis multiplex congenita, and Larsen's syndrome.
