全膝关节翻修术中骨缺损的处理研究进展

Research progress on treatment of bone defects in total knee revision

全膝关节翻修术是重建关节结构,恢复关节功能的有效方法之一。在关节翻修术中不容忽视的一个问题是由松动、感染、医疗操作等引起的骨缺损。近年来,随着全膝关节置换术的广泛应用和接受关节置换术患者的年轻化,全膝关节翻修术的数量也在不断增加,关于全膝关节翻修术中处理骨缺损的报道也越来越多。翻修术的假体选择对于手术结果十分重要,近年来这一问题的研究也更加深入,多元化。关于骨缺损处理的研究不仅仅在于传统的骨水泥,植骨等方法,还有基于新的理念所开发出的金属垫块、3D打印等方法。在临床上,应当根据具体情况,采用合适的方法治疗,重建关节力线,恢复关节功能。

Total knee revision surgery is to reconstruct the joint structure. It’s an effective way to restore joint function. One of the problems in joint revision surgery is bone defects caused by loosening,infection,medical procedures and other factors. In recent years,with the widespread use of total knee arthroplasty（ TKA） and the younger patients receiving arthroplasty,the number of TKA revision is also on the rise,and reports of treatment of bone defects in t TKA is more. The choice of prosthesis for revision surgery is very important for the outcome of the surgery. In recent years,the study of this issue has also deepened and diversified. The study on the treatment of bone defects not only lies in the traditional methods such as bone cement and bone grafting,but also the methods of metal pads and 3D printing developed based on the new concept. In clinical practice,appropriate methods should be used to rebuild joint lines,and restore joint function.
