The purpose of this study was to determine the functional outcome and implant survivorship of mobile-bearing total ankle arthroplasty (TAA) performed by a single surgeon.
We reviewed 205 consecutive patients (210 ankles) who had undergone mobile-bearing TAA (205 patients) for osteoarthritis of the ankle between January 2005 and December 2015. Their mean follow-up was 6.4 years (2.0 to 13.4). Functional outcome was assessed using the Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, 36-Item Short-Form Health Survey (SF-36) score, visual analogue scale, and range of movement. Implant survivorship and complications were also evaluated.
There were significant improvements in all functional outcome categories between the preoperative and final follow-up assessments (p < 0.001). Patients showed marked improvement in clinical outcomes in terms of pain, function, and quality of life. The overall implant survivorship was 91.7% at a mean follow-up of 6.4 years. In all, 33 major complications were identified with a 15.7% rate, resulting in 12 prosthesis failures (5.7%). Periprosthetic osteolysis (19 cases; 9.0%) was the most frequent complication.
Mobile-bearing TAA resulted in improved functional outcomes, a low major complication rate, and excellent implant survivorship at a mean follow-up of 6.4 years. Cite this article: 2019;101-B:695-701.
本研究旨在确定由一位外科医生进行的活动平台全踝关节置换术（TAA）的功能结果和植入物存活率。
我们回顾了 2005 年 1 月至 2015 年 12 月期间因踝关节骨关节炎接受活动平台 TAA（205 例患者）的 205 例连续患者（210 例踝关节）。他们的平均随访时间为 6.4 年（2.0 至 13.4）。使用踝关节骨关节炎量表、美国矫形足踝协会（AOFAS）踝关节后足评分、36 项简明健康调查（SF-36）评分、视觉模拟评分和活动范围评估功能结果。还评估了植入物存活率和并发症。
在术前和最终随访评估之间，所有功能结果类别均有显著改善（p < 0.001）。患者在疼痛、功能和生活质量方面的临床结局方面表现出明显的改善。在平均 6.4 年的随访中，总体植入物存活率为 91.7%。共有 33 例主要并发症，发生率为 15.7%，导致 12 例假体失败（5.7%）。最常见的并发症是假体周围骨溶解（19 例；9.0%）。
在平均 6.4 年的随访中，活动平台 TAA 可改善功能结果，降低主要并发症发生率，并且植入物存活率高。
