Unilateral congenital knee dislocation: effective conservative treatment

Congenital knee dislocation (CKD) is a rare condition; it occurs when the femoral condyle is posteriorly placed in relation to the proximal articular surface of the tibia. This displacement can happen in isolation or in association with other syndromes. Physical examination at birth is important in diagnosing CKD, with many classifications that guide its diagnosis and treatment. We report a case of a newborn male diagnosed with isolated right CKD. On examination, the diagnosis was confirmed as grade II CKD using the Tarek classification. Serial casting was adopted as initial conservative management which resulted in cumulative improvement. The child was followed up to the age of 1 year at which time he showed a complete range of motion and normal motor development.
