计算力学在骨科生物力学的各个领域都得到了发展。本文的目的是提供一个一般性的审查的计算模型，用于在不同的负载和病理条件下的膝关节的力学功能的分析。首先对相关领域发表的主要综述文章进行了综述。简要讨论了膝关节软组织的本构模型，以便于理解关节建模。随后对胫股关节模型进行了详细的综述。讨论了几何重构的步骤以及有限元建模中的一些关键问题。如果模型构建正确，计算建模可以成为研究膝关节力学行为的一种可靠而有效的方法。单相材料模型已用于预测健康膝关节和修复关节的瞬时载荷响应，例如全膝关节和部分膝关节切除术、ACL和PCL重建以及关节置换。最近，孔隙力学模型占流体加压软组织已被提出来研究健康和受损的膝关节的粘弹性响应。虽然本构建模在组织水平上已经有了相当大的进步，但在将良好的材料模型应用于三维关节模拟方面仍然存在许多挑战。在联合水平上的完整的模型验证目前似乎是不可能的，因为只能通过实验获得简单的数据。因此，模型验证可以集中在使用组织的多个力学测试的本构律上。在联合层面上进行广泛的模型验证对于建模的准确性仍然至关重要。
Computational mechanics has been advanced in every area of orthopedic biomechanics. The objective of this paper is to provide a general review of the computational models used in the analysis of the mechanical function of the knee joint in different loading and pathological conditions. Major review articles published in related areas are summarized first. The constitutive models for soft tissues of the knee are briefly discussed to facilitate understanding the joint modeling. A detailed review of the tibiofemoral joint models is presented thereafter. The geometry reconstruction procedures as well as some critical issues in finite element modeling are also discussed. Computational modeling can be a reliable and effective method for the study of mechanical behavior of the knee joint, if the model is constructed correctly. Single-phase material models have been used to predict the instantaneous load response for the healthy knees and repaired joints, such as total and partial meniscectomies, ACL and PCL reconstructions, and joint replacements. Recently, poromechanical models accounting for fluid pressurization in soft tissues have been proposed to study the viscoelastic response of the healthy and impaired knee joints. While the constitutive modeling has been considerably advanced at the tissue level, many challenges still exist in applying a good material model to three-dimensional joint simulations. A complete model validation at the joint level seems impossible presently, because only simple data can be obtained experimentally. Therefore, model validation may be concentrated on the constitutive laws using multiple mechanical tests of the tissues. Extensive model verifications at the joint level are still crucial for the accuracy of the modeling.
