Case:Juvenile rheumatoid arthritis (JRA) is associated with severe flexion contracture of the knees disabling a patient's ability to walk. Although various treatment modalities are available in the literature, we report a 2-stage procedure in a case of a 22-year-old female JRA patient with bilateral severe flexion deformity of the knee: stage 1—correction of the flexion contracture deformity by ring fixators and stage 2—total knee arthroplasty (TKA) for arthritis. To the best of our knowledge, no such approach has been reported previously.Conclusions:An Ilizarov ring fixator is a safe technique for gradual correction of a severe flexion deformity. Subsequent TKA can be performed as a standard procedure.
