The ankle is a complex joint, anatomically and biomechanically. Pathologically diseased ankle joints, which require surgical intervention, now have the option of a total ankle replacement system rather than the long-standing arthrodesis procedure, first described by Albert in 1878. The anatomical features and forces acting across the joint are important when designing total ankle replacement (TAR) systems. This review discusses the history and evolution of TAR prosthetic systems and considers how the ankle's normal physiology and biomechanics is incorporated into their design. The Scandinavian total ankle replacement (STAR) is a three component prosthetic system and this review concludes that its size, shape and surgical insertion technique allows the biomechanical requirements of the ankle to be met with an adequate stress distribution in particular.
踝关节是一个复杂的关节，在解剖学和生物力学上都是如此。患有病理疾病的踝关节需要手术干预，现在可以选择全踝关节置换系统，而不是早在 1878 年 Albert 首次描述的关节融合术。在设计全踝关节置换 (TAR) 系统时，关节的解剖特征和作用于关节的力很重要。本文回顾了 TAR 假体系统的历史和演变，并探讨了如何将踝关节的正常生理学和生物力学纳入其设计中。斯堪的纳维亚全踝关节置换 (STAR) 是一种三组件假体系统，本文的结论认为，其大小、形状和手术插入技术允许满足踝关节的生物力学要求，并特别实现适当的应力分布。
