Abstract

This is a report of three cases of congenital dislocation of the knee with the chief complaint of extension contracture knee, seen at the Severance Hospital Department of Orthopedic Surgery from January 1975 to the present time(April, 1978). In the first case, the dislocated knee was associated with congenital dislocation of the hip and congenital club foot. Family history revealed that the elder brother of the patient had died of complications of premature birth. The second case appeared to be an isolated congenital dislocation of the knee, without associated anomalies or relevent history in the family. In the third case, the dislocated knee was associated with adducted thumbs and genu valgum, as well as congenital dislocation of the hip and congenital club foot, although family history was irrelevant. In all the cases roentgenographic examinations revealed in the lateral view that the tibia was displaced anteriorly in relationship to the femur. Two cases were treated by four or five successive corrective castings, each lasting one week to ten days. It is contemplated that the third case will also be treated by a simillar corrective cast immobilization. Following this course of treatment, each of the two dislocated knees was completely reduced and the original limitation of flexion improved. Experience with these two cases suggests that good results may be obtained with conservative treatment in congenital dislocation of the knee. A brief review of the literature is submitted.
