Few studies have outlined the outcomes and complications in Asians undergoing total ankle arthroplasty. This study reports the functional, radiological outcomes and satisfaction rates in our Asian population.
Patients who underwent primary total ankle arthroplasty from 2007 to 2013 were recruited. Outcomes evaluated were the AOFAS Ankle-Hindfoot Score (AHS), Visual Analogue Scale (VAS), and the Short Form 36 (SF-36)questionnaire. Outcome scores were collected prospectively up to 2 years. Patient satisfaction was evaluated on a 6-point scale based on North American Spine Society Low Back Pain Instrument and classified as satisfied or unsatisfied.
Forty-one patients underwent primary total ankle arthroplasty. All patients experienced improvements in AHS, VAS, and Mental Component Summary score of the SF-36 at both 6-month and 2-year postoperative interval. The mean AHS score improved from 35 ± 19 points preoperatively to 64 ± 24 at 6 months (P<.001) and 72 ± 26 at 24 months (P <.001). VAS scores improved from 7 ± 2 preoperatively to 3 ± 3 (P < .001) at 6 and 24 months. The Physical Component Summary (PCS) of the SF-36 has an established minimum clinically important difference (MCID) of 5. The mean improvement in PCS in our cohort met this MCID for the PCS; 63% and 71% of patients were satisfied with the procedure at 6 months and 2 years postoperatively, respectively. Revision rate in this series was 9.7%.
Total ankle arthroplasty has good patient satisfaction rates, with favorable early clinical outcome in Asian patients.
Therapeutic, Level II.
很少有研究概述亚洲人接受全踝关节置换术的结果和并发症。本研究报告了我们亚洲人群的功能、影像学结果及满意度。
招募2007年至2013年接受初次全踝关节置换术的患者。评估的结果包括美国足踝外科协会（AOFAS）踝-后足评分（AHS）、视觉模拟量表（VAS）和简明健康状况调查量表（SF-36）问卷。前瞻性收集长达2年的结果评分。根据北美脊柱协会下腰痛工具，采用6分制评估患者满意度，并分为满意或不满意。
41例患者接受了初次全踝关节置换术。所有患者在术后6个月和2年时，AHS、VAS以及SF-36的心理成分总分均有改善。AHS平均评分从术前的35±19分提高到术后6个月时的64±24分（P<.001），24个月时为72±26分（P<.001）。VAS评分从术前的7±2分改善到6个月和24个月时的3±3分（P<.001）。SF-36的生理成分总分（PCS）已确定的最小临床重要差异（MCID）为5。我们队列中PCS的平均改善达到了PCS的这一MCID；术后6个月和2年时，分别有63%和71%的患者对手术满意。本系列的翻修率为9.7%。
全踝关节置换术患者满意度高，亚洲患者早期临床效果良好。
治疗性，二级。
