Background: Congenital Dislocation of the Knee (CDK) is a rare birth abnormality. It may be associated with conditions like Arthrogryposis, spinal dysraphism, Larsen’s, Beal’s or Ehler Danlos’ syndromes & with other deformities like developmental dysplasia of the hip or clubfoot. There are several differences of opinion regarding the management of this condition. Serial casting is a primary line of management for this condition which if started early can give good results & might avoid surgical intervention. Objective: This study aims to study the functional outcome of Congenital Dislocation of the Knee treated with serial casting. Materials and Methods: This was a prospective study of 3 Newborn babies with Congenital dislocation of knee at a Tertiary Care Hospital. All 3 children were treated with serial casting with above knee cast with increasing degree of knee flexion. Regular follow up was done. Investigations were done to rule out syndromic associations. Initial conservative management was planned. Results: Mean follow up was 16 months. All 3 babies showed >90 degree of knee flexion with stable knee & 5/5 Quadriceps strength & thus had Excellent results. No surgical intervention was required. Conclusion: Congenital Dislocation of the knee is a rare abnormality, for which primary line of treatment is serial casting & follow up. If failed or with poor results, surgical intervention can be planned. Early detection of other abnormalities & syndromic associations is of utmost importance.
