The incidence of revision total knee arthroplasty (TKA) has grown tremendously the past decade, and all projections suggest that it will continue to increase during the next 25 years. Although primary TKA remains one of the most successful orthopedic procedures, revision TKA has not as well. Failure rates for revision TKA remain significantly higher than those for primary TKA. New revision systems should be developed with new implants and instrumentation to address the difficulties frequently experienced with revision TKA. In this article, design surgeons report on the development of a new system and the early clinical experience with its use. The researchers believe that this new system is easy to use and facilitates accurate implantation, which could improve revision TKA outcomes.
在过去十年中，全膝关节置换翻修术（TKA）的发生率急剧上升，所有预测都表明在未来25年中该发生率将持续增长。尽管初次全膝关节置换术仍然是最成功的骨科手术之一，但全膝关节置换翻修术却并非如此。全膝关节置换翻修术的失败率仍显著高于初次全膝关节置换术。应该研发新的翻修系统，配备新的植入物和器械，以解决全膝关节置换翻修术中经常遇到的难题。在本文中，参与设计的外科医生报告了一种新系统的研发情况及其早期临床应用经验。研究人员认为，这种新系统易于使用，有助于精确植入，有望改善全膝关节置换翻修术的效果。
