Abstract : Fixed flexion deformity (FFD) of the knee causes significant patient disability and is challenging to orthopedic surgeons because of its complexity. A prospective study was conducted using Ilizarovg's principles of distraction neohistogenesis and differential distraction and Ilizarovg's ring fixator for the correction of this deformity in cases with soft-tissue contracture. This was done without any concurrent bony procedures. A prospective, uncontrolled study of 26 patients (39 knees) was conducted over a 4-year period with prior approval from the local institutional review board. Patients with FFD of the knee without bony ankylosis were treated with knee-spanning 4-ring Ilizarovg's frame and gradual differential distraction. All patients showed complete correction of deformity without any significant complications. The results of this uncontrolled study permit the observation that soft-tissue distraction across a joint using Ilizarovg's principle results in soft-tissue lengthening and correction of joint deformity caused by contractures. This technique needs further detailed examination. © 2010 The Author(s).
