The aim of this study was to investigate the surgical trends of primary total ankle arthroplasty (TAA) and revision procedure in Korea from 2007 to 2017 using national population-based data.
We reviewed the National Health Insurance data of Korea from 2007 to 2017. The data included diagnosis codes, procedure codes, prescriptions, medical costs, and other demographic data. Trends of primary diagnosis for primary TAA were evaluated. Annual trends and incidences per 100,000 person-years of primary TAA and revision procedures as well as compound annual growth rate (CAGR) during the study period were analysed. Surgical trends according to patients' age, hospital grades, and insurance systems were also evaluated.
Primary diagnosis for primary TAA was mostly degenerative arthritis (6,501 cases; 90.5%). From 2007 to 2017, the total number of cases of primary TAA and revision procedures was 7,183 and 585, respectively. The number of cases in 2007 of primary TAA was 313; there were no cases of revision. The number of cases in 2017 of primary TAA were 986 and of revision were 108. The CAGR during this period was 28.6% for primary TAA and 44.6% for revision procedures. Incidences per 100,000 person-years in 2017 were 1.91 for primary TAA and 0.21 for revision procedures. The average cost paid by patients themselves was USD 813 (19%) and by the National Health Insurance Service was USD 3,480 (81%).
The incidence of primary TAA and revision procedures steadily increases in Korea during the 11-year study period.
本研究旨在使用全国人群数据调查 2007 年至 2017 年韩国初次全踝关节置换术（TAA）和翻修手术的手术趋势。
我们回顾了 2007 年至 2017 年韩国的国家健康保险数据。该数据包括诊断代码、手术代码、处方、医疗费用和其他人口统计学数据。评估了初次 TAA 的主要诊断的趋势。分析了研究期间每年初次 TAA 和翻修手术的发生率（每 10 万人年）以及复合年增长率（CAGR）。还根据患者年龄、医院等级和保险制度评估了手术趋势。
初次 TAA 的主要诊断为退行性关节炎（6501 例；90.5%）。2007 年至 2017 年，初次 TAA 和翻修手术的总病例数分别为 7183 例和 585 例。2007 年初次 TAA 病例数为 313 例，无翻修病例。2017 年初次 TAA 病例数为 986 例，翻修病例数为 108 例。在此期间，初次 TAA 的复合年增长率为 28.6%，翻修手术为 44.6%。2017 年每 10 万人年的发生率分别为 1.91 例和 0.21 例。患者自费 813 美元（19%），国家健康保险服务支付 3480 美元（81%）。
在 11 年的研究期间，韩国初次 TAA 和翻修手术的发生率稳步上升。
