有限元分析在胫骨高位截骨治疗膝内侧间室骨关节炎的研究进展

Research progress of finite element analysis on high tibial osteotomy for treatment of the medial knee compartmental osteoarthritis

膝内侧间室骨关节炎是中老年常见的退行性疾病,是导致残疾的常见原因。胫骨高位截骨术是治疗膝内侧间室骨关节炎的有效方法,但适应证选择和手术难度大,若选择和操作不当会导致临床疗效差和骨关节炎进展;有限元分析是目前模拟分析胫骨高位截骨术后膝关节应力分布和预测手术疗效的主要方法。本文对有限元分析在胫骨高位截骨术后膝关节应力分布和改变及内置物的设计和安放研究进展等进行分析总结,为临床提供理论参考,提高手术和临床疗效。

Medial compartmental osteoarthritis of the knee is a common degenerative disease and the cause of disability in the middleaged and elderly. High tibial osteotomy(HTO) has been proved an effective treatment for medial compartment osteoarthritis of the knee.However, the indication selection and surgical technique of HTO remain difficulties in some extent. Improper indication selection or poor surgical manipulation will lead to unacceptable clinical outcome, even accelerate osteoarthritis progression. At present, finite element analysis is the main method to simulate the stress distribution of knee joint after HTO and predict the clinical outcomes. In this paper, finite element analysis on knee stress distribution and its variations after high tibial osteotomy, as well as the design and placement of implants were analyzed and summarized to provide a theoretical reference for clinical practice to improve surgical efficacy and clinical results.
