Typically, joint arthroplasty is performed to relieve pain and improve functionality in a diseased or damaged joint. Total knee arthroplasty (TKA) involves replacing the entire knee joint, both femoral and tibial surfaces, with anatomically shaped artificial components in the hope of regaining normal joint function and permitting a full range of knee flexion. In spite of the design of the prosthesis itself, the degree of flexion attainable following TKA depends on a variety of factors, such as the joint's preoperative condition/flexion, muscle strength, and surgical technique. High-flexion knee prostheses have been developed to accommodate movements that require greater flexion than typically achievable with conventional TKA; such high flexion is especially prevalent in Asian cultures. Recently, computational techniques have been widely used for evaluating the functionality of knee prostheses and for improving biomechanical performance. To offer a better understanding of the development and evaluation techniques currently available, this paper aims to review some of the latest trends in the simulation of high-flexion knee prostheses.
通常情况下，进行关节置换术是为了缓解患病或受损关节的疼痛并改善其功能。全膝关节置换术（TKA）包括用解剖形状的人工部件替换整个膝关节，即股骨和胫骨表面，以期恢复正常关节功能并实现膝关节的全范围屈曲。尽管假体本身有其设计，但TKA术后可达到的屈曲程度取决于多种因素，如关节的术前状况/屈曲度、肌肉力量和手术技术。高屈曲度膝关节假体已被研发出来，以适应比传统TKA通常所能达到的更大屈曲度的运动；这种高屈曲度在亚洲文化中尤为普遍。最近，计算技术已被广泛用于评估膝关节假体的功能和改善生物力学性能。为了更好地理解目前可用的开发和评估技术，本文旨在综述高屈曲度膝关节假体模拟方面的一些最新趋势。
