The design of total ankle arthroplasty systems is evolving as a result of findings from longer-term studies. Our understanding of modes of failure has increased, and surgical techniques have become more refined. Currently, five total ankle arthroplasty systems are used in the United States. The landscape has changed considerably in the decade since the latest article reviewing total ankle design was published. Some implants with acceptable intermediate results had much poorer outcomes at 7- to 10-year follow-up. As more research showing mid- to long-term outcomes is published, the design rationale and current outcomes data for each of these implants must be considered.
随着长期研究结果的出现，全踝关节置换系统的设计也在不断发展。我们对失效模式的认识有所提高，手术技术也变得更加精细。目前，全踝关节置换系统在美国有五种。自最新的全踝关节设计综述文章发表以来，在过去的十年中，这一领域已经发生了很大的变化。一些中期结果可接受的植入物在 7 到 10 年的随访中结果要差得多。随着越来越多的研究显示中期到长期的结果，必须考虑这些植入物的设计原理和当前的结果数据。
