The incidence of unilateral minor heterotopic ossification after primary total knee arthroplasty is still unknown, but bilateral severe heterotopic ossification is rare and has not been reported before. Presented in this report is a 60-year-old female patient who developed bilateral knee pain and stiffness 2 weeks after primary total knee arthroplasty. Her weight was 70 kg and body mass index was 32.2. Preoperatively, she had bilateral varus deformity of both knees. X-rays taken 3 months after surgery revealed bilateral severe heterotopic ossification. The patient had been on non-operative treatment (including anti-inflammatory drugs and physiotherapy). There was a marked improvement 6 months after surgery. This case report showed the non-operative treatment may produce acceptable results for patients with severe bilateral heterotopic ossification after primary total knee arthroplasty, and exerted no influence on the final clinical outcome.
初次全膝关节置换术后单侧轻度异位骨化的发生率尚不清楚，但双侧严重异位骨化较为罕见，此前未见报道。本报告介绍了一名60岁女性患者，她在初次全膝关节置换术后2周出现双侧膝关节疼痛和僵硬。她体重70公斤，体重指数为32.2。术前，她双膝均有内翻畸形。术后3个月的X线片显示双侧严重异位骨化。患者接受了非手术治疗（包括抗炎药物和物理治疗）。术后6个月有明显改善。本病例报告表明，非手术治疗对于初次全膝关节置换术后双侧严重异位骨化的患者可能产生可接受的结果，且对最终临床结局无影响。
