Triple knee deformity is one of the rare sequelae following tuberculosis infection. It includes flexion of the knee, posterolateral subluxation of tibia and external rotation of tibia over femoral condyles presenting in coalition and leading to debilitating deformity. Currently various modalities of operative intervention are mentioned in the literature consisting of Ilizarov ring fixator or limb reconstruction system application (pediatric age group), total knee arthroplasty, arthrodesis coupled with synovectomy. Eleven years old male presented to orthopedics outpatient department with pain, swelling and loss of movement of left knee since two years. Swelling was insidious in onset and gradually progressed over the duration of two years leading to deformity which has aggravated so much so that patient is unable to do any movements of left knee joint. Patient was on anti-tubercular regime for 6 months due to which swelling subsided minimally but the deformity persisted even after sustained traction. On local examination knee was fixed in flexion in 100 degrees. Hamstring contracture was seen in posterior aspect with severe wasting of hamstring and quadriceps muscle. Patient was managed with Illizarov fixator application. Two straight wires were passed ten cm distal to first ring and attached to ring. Two Straight wires were passed at distal femur, proximal to second ring and attached to ring. Currently the patient is being managed with periodic distraction of Ilizarov ring about 0.25 mm per day.
