We performed a retrospective review of a consecutive series of 178 Mobility total ankle replacements (TARs) performed by three surgeons between January 2004 and June 2009, and analysed radiological parameters and clinical outcomes in a subgroup of 129 patients. The mean follow-up was 4 years (2 to 6.3). A total of ten revision procedures (5.6%) were undertaken. The mean Ankle Osteoarthritis Scale (AOS) pain score was 17 (0 to 88) and 86% of patients were clinically improved at follow-up. However, 18 patients (18 TARs, 14%) had a poor outcome with an AOS pain score of > 30. A worse outcome was associated with a pre-operative diagnosis of post-traumatic degenerative arthritis. However, no pre- or post-operative radiological parameters were significantly associated with a poor outcome. Of the patients with persistent pain, eight had predominantly medial-sided pain. Thirty TARs (29%) had a radiolucency in at least one zone. The outcome of the Mobility TAR at a mean of four years is satisfactory in > 85% of patients. However, there is a significant incidence of persistent pain, particularly on the medial side, for which we were unable to establish a cause.
我们对 2004 年 1 月至 2009 年 6 月期间三位医生连续进行的 178 例 Mobility 全踝关节置换术（TAR）进行了回顾性研究，并对其中 129 例患者的亚组进行了影像学参数和临床结果分析。平均随访时间为 4 年（2 至 6.3 年）。共进行了 10 次翻修手术（5.6%）。平均踝关节骨关节炎评分（AOS）疼痛评分为 17 分（0 至 88 分），86%的患者在随访时临床改善。然而，18 名患者（18 例 TAR，14%）的 AOS 疼痛评分>30，结果较差。较差的结果与术前创伤后退行性关节炎的诊断有关。然而，术前或术后的影像学参数与较差的结果均无显著相关性。在持续疼痛的患者中，有 8 名患者主要表现为内侧疼痛。30 个 TAR（29%）在至少一个区域存在放射性透亮区。在平均 4 年的随访中，超过 85%的 Mobility TAR 患者的结果是满意的。然而，仍有相当比例的患者存在持续性疼痛，特别是在内侧，我们未能确定其原因。
