This is a case of a 16 year old male with a marked valgus deformity of the right knee. Two years prior to consult, the patient sustained a closed Salter Harris type 2 fracture of the distal femur when he was bumped by a vehicle. The injury was treated by open reduction and cross pinning using Steinmann pins. The knee progressively became deformed.

Management (2 stages):
1). Correction of angular deformity and limb length discrepancy by using Ilizarov Method
2). Reduction of patellar dislocation by transfer of tibial tubercle (Fulkerson technique)
