Total ankle arthroplasty (TAA) is being carried out with increasing frequency and manufacturers are releasing new implant designs each year.
We comment on the various designs and the outcome of the procedure as reported in the literature. No results have so far been published on the majority of the more recent designs and where outcome data are available, the follow up period is very short.
For those designs where 5 or 10 year follow-up studies have been performed, the survivorship at 5 years is over 90% in most instances and of the order of 80% at 10 years. The failure rate is lower in ankles that are well aligned at presentation than it is for those with more than 15 degrees varus or valgus deformity pre-operatively.
TAA has definite advantages over fusion for some patients and if selection criteria are adhered to, a long-lasting satisfactory outcome can be achieved.
全踝关节置换术（TAA）的实施频率日益增加，制造商每年都在推出新的植入物设计。
我们对文献中报道的各种设计及该手术的结果进行评论。目前，大多数最新设计尚未发表相关结果，而在有结果数据的情况下，随访期非常短。
对于那些进行了5年或10年随访研究的设计，多数情况下5年生存率超过90%，10年约为80%。术前踝关节对线良好者的失败率低于术前有超过15度内翻或外翻畸形者。
对于某些患者，全踝关节置换术相对于融合术具有明显优势，若遵循选择标准，可实现长期满意的效果。
