Total ankle replacement (TAR) is considered as a treatment option for end stage ankle arthritis. This treatment was abandoned due to the early failure prosthesis in the past. However, with recently advancements in ankle prosthesis design and improved surgical techniques, TAR has made great progress and the indications are expanding. Many studies have shown acceptable mid term and long term results of TAR, and it is worth looking forward to the prospect. Advantages of TAR over arthrodesis include improvement in joint range of motion, better gait activity, and decreased incidence of adjacent joint arthritis. With the further development, TAR will be considered as gold standard for the treatment of end stage ankle arthritis instead of the ankle arthrodesis. However, there are still many problems of TAR need to be solved in this present stage of development, including higher economic costs, lower survival rate, and higher revision rate. Patients and surgeons should have confidence in TAR, also need to choose this treatment with careful consideration.
全踝关节置换术（TAR）被视为终末期踝关节关节炎的一种治疗选择。过去，由于假体早期失败，这种治疗方法被放弃。然而，随着近期踝关节假体设计的进步和手术技术的改进，TAR取得了巨大进展，适应证也在不断扩大。许多研究表明TAR的中期和长期结果是可以接受的，其前景值得期待。TAR相对于关节融合术的优势包括关节活动范围改善、步态活动更好以及相邻关节关节炎发病率降低。随着进一步发展，TAR将被视为终末期踝关节关节炎治疗的金标准，而非踝关节融合术。然而，在当前的发展阶段，TAR仍有许多问题需要解决，包括更高的经济成本、更低的生存率和更高的翻修率。患者和外科医生应对TAR有信心，但也需要谨慎考虑后再选择这种治疗方法。
