Flexion contracture deformities, as well as severe varus and valgus deformities of the knee joint, accompany osteoarthritis or rheumatoid arthritis (RA). In particular, severe flexion contracture deformity of the knee joint is often found in patients with RA, which renders them nonambulatory. This report describes a 26-year-old female patient diagnosed with RA 10 years ago. She had chronic joint pain, severe flexion contracture, valgus deformity in both knees, and limited range of motion in both knees and became nonambulatory. She underwent a total knee arthroplasty (TKA) and serial casting and physical therapy to restore stable joint movement and correct knee joint deformity. Her pain was successfully relieved, and she was able to walk after surgery. Here, we report the excellent results of TKA in this RA patient with severe flexion contracture of both knees.
膝关节的屈曲挛缩畸形以及严重的内翻和外翻畸形，常伴随骨关节炎或类风湿关节炎（RA）出现。特别是，膝关节严重屈曲挛缩畸形在类风湿关节炎患者中较为常见，这会导致患者无法行走。本报告描述了一名26岁女性患者，她在10年前被诊断为类风湿关节炎。她患有慢性关节疼痛、严重屈曲挛缩、双膝外翻畸形以及双膝活动范围受限，已无法行走。她接受了全膝关节置换术（TKA）以及连续的石膏固定和物理治疗，以恢复关节的稳定活动并矫正膝关节畸形。术后她的疼痛得到了成功缓解，能够行走。在此，我们报告了全膝关节置换术在这位双膝严重屈曲挛缩的类风湿关节炎患者中取得的优异效果。
