Supplementary Material for: Successful Early Non-Operative Management of Congenital Knee Dislocation: Demonstration via a Case Report

Congenital knee dislocation (CKD) is a deformity in which unnatural hyperextension is possible at the knee much beyond the normal 0° full extension while the flexion is severely restricted. Incidence of this rare congenital malformation is 1/100,000 live births. We present a clinical case of unilateral CKD in a 2-week-old female child and our approach of treatment using serial casting. We have been able to demonstrate that if initiated early, within first few weeks of life, the congenital deformity of knee can be managed conservatively without any surgical intervention even in higher grades.
