Periprosthetic fractures (PPFs) around the knee following total knee arthroplasty (TKA) present a significant challenge in orthopedic management, particularly in patients with rheumatoid arthritis (RA). These fractures are influenced by factors such as bone stock quality, prosthetic status, polyethylene wear, and fracture reducibility. Proper classification and management strategies are essential to optimize outcomes and prevent complications.
A 52-year-old female with RA sustained a right knee PPF following a trivial fall. Clinical and radiographic evaluation classified the fracture based on prosthetic stability and bone quality:• Type II fracture with a loose prosthesis requiring revision surgery.She underwent staged revision TKA including:1.Definitive surgery with revision TKA and bone grafting in figure.2.Postoperative rehabilitation to restore function figure.
Management of PPFs in RA patients requires a comprehensive approach, including preoperative planning, prosthetic evaluation, osteoporosis management, and staged surgical intervention when necessary. This case highlights the importance of addressing osteoporosis alongside osteoarthritis in improving TKA outcomes. Further research is needed to refine treatment strategies for PPFs in RA patients.
全膝关节置换术(TKA)后膝关节周围的假体周围骨折(PPF)在骨科治疗中是一项重大挑战,尤其是在类风湿关节炎(RA)患者中。这些骨折受骨量质量、假体状况、聚乙烯磨损和骨折复位性等因素影响。正确的分类和管理策略对于优化治疗结果和预防并发症至关重要。
一名52岁的类风湿关节炎女性在轻微跌倒后发生右膝PPF。临床和影像学评估根据假体稳定性和骨质对骨折进行分类:
• Ⅱ型骨折,假体松动,需要翻修手术。
她接受了分期翻修TKA,包括:
确定性手术,进行翻修TKA并如图所示植骨。
术后康复以恢复功能,如图所示。
RA患者PPF的管理需要综合方法,包括术前规划、假体评估、骨质疏松管理以及必要时的分期手术干预。该病例突出了在改善TKA结果方面同时解决骨质疏松和骨关节炎问题的重要性。需要进一步研究以完善RA患者PPF的治疗策略。
