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.
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.
幼年特发性关节炎（JRA）可导致膝关节严重屈曲挛缩，使患者丧失行走能力。尽管文献中已有多种治疗方法，但我们报告了一例 22 岁女性 JRA 患者双侧膝关节严重屈曲畸形的 2 期手术：第 1 期通过环形固定器矫正屈曲挛缩畸形，第 2 期进行全膝关节置换术（TKA）治疗关节炎。据我们所知，此前尚无此类方法的报道。
伊利扎洛夫环形固定器是一种安全的技术，可逐渐矫正严重的屈曲畸形。随后可进行标准的 TKA 手术。
