Total knee arthroplasty (TKA) is a widely performed surgical procedure known for its favorable long-term outcomes. However, postoperative infection poses significant treatment challenges and may lead to severe complications. This case involves a 55-year-old woman who developed a patellar fracture following TKA, complicated by deep infection after osteosynthesis and accompanied by loss of extensor mechanism. Despite undergoing multiple surgeries, the treatment process proved difficult. Ultimately, knee arthrodesis with bilateral plates was performed using the Masquelet technique. The postoperative course was favorable, with successful bone union achieved. Although the patient experienced a leg length discrepancy, she regained the ability to walk short distances. Knee arthrodesis employing the Masquelet technique proved effective for infection control, bone regeneration, and management of extensor mechanism deficiency, making it a viable treatment option for managing postoperative infections after TKA.
全膝关节置换术(TKA)是一种广泛开展的外科手术,以其良好的长期效果而闻名。然而,术后感染带来了重大的治疗挑战,并可能导致严重并发症。本病例涉及一名55岁女性,她在全膝关节置换术后发生髌骨骨折,接骨术后并发深部感染,并伴有伸肌机制丧失。尽管接受了多次手术,但治疗过程仍很困难。最终,采用Masquelet技术使用双侧钢板进行了膝关节融合术。术后过程顺利,实现了成功的骨愈合。尽管患者存在腿长差异,但她恢复了短距离行走的能力。采用Masquelet技术的膝关节融合术被证明对控制感染、促进骨再生和处理伸肌机制缺陷有效,使其成为治疗全膝关节置换术后感染的可行治疗选择。
