Total ankle replacement (TAR) is an effective operative treatment of end-stage ankle osteoarthritis (OA) in the appropriate patient, conferring improved kinematic function, decreased stress across adjacent joints, and offering equivalent pain relief in comparison to ankle arthrodesis (AA). It is important to consider patient age, weight, coronal tibiotalar deformity, joint line height, and adjacent joint OA to maximize clinical and patient outcomes. Both mobile-bearing and fixed-bearing implants have demonstrated favorable clinical outcomes, marked improvement in patient-reported outcomes, and good survivorship; however, implant survivorship decreases with longer term follow-up, necessitating constant improvement of primary and revision TAR options.
全踝关节置换术（TAR）是治疗晚期踝关节炎（OA）的有效手术方法，可改善运动功能，降低相邻关节的压力，并提供与踝关节融合术（AA）相当的止痛效果。考虑患者的年龄、体重、冠状距骨畸形、关节线高度和邻近关节 OA 对于获得最佳的临床和患者结局至关重要。无论是活动平台还是固定平台的植入物，都已显示出良好的临床效果、患者报告结果的显著改善和较高的生存率；然而，随着随访时间的延长，植入物的生存率下降，这需要不断改进初次和翻修 TAR 选择。
