BACKGROUND
Methodological quality and author internationality are increasing in orthopaedic surgery. The purpose of this study was to evaluate the methodological quality and author geography trends from 1994 to 2019 in high-quality foot and ankle journals.
METHODS
Analyses of 1,242 foot and ankle publications in Foot and Ankle International, American Journal of Bone and Joint Surgery, and American Journal of Sports Medicine were done for 1994, 1999, 2004, 2009, 2014, and 2019. Articles were classified according to study type, level of evidence (LOE), and author's country of publication.
RESULTS
The most common clinical study was therapeutic (65.4). Significant increases were noted in the proportion of therapeutic (P < 0.01) and prognostic (P < 0.01) articles. The average LOE increased from 3.96 ± 1.01 to 3.19 ± 0.97 (P < 0.01). The proportion of Level I (P = 0.29) and level IV articles (P = 0.21) remained constant, level II (P < 0.01) and level III (P < 0.01) articles increased, and level V (P < 0.01) articles decreased. United States authorship decreased from 78.1% in 1994 to 44.8% in 2009, then remained constant through 2019 (P < 0.01).
CONCLUSION
This study demonstrated an improvement in LOE of foot and ankle publications across a 25-year period in three high-quality orthopaedic journals. Increasing internationality was also observed.
背景
骨科手术的方法学质量和作者国际化程度正在提高。本研究的目的是评估高质量足踝期刊从 1994 年到 2019 年的方法学质量和作者地域趋势。
方法
对 1994 年、1999 年、2004 年、2009 年、2014 年和 2019 年《足踝国际》、《美国骨科与关节外科杂志》和《美国运动医学杂志》的 1242 篇足踝文献进行分析。文章根据研究类型、证据水平（LOE）和作者所在国家进行分类。
结果
最常见的临床研究是治疗性的（65.4%）。治疗性（P < 0.01）和预后性（P < 0.01）文章的比例显著增加。平均 LOE 从 3.96 ± 1.01 增加到 3.19 ± 0.97（P < 0.01）。I 级（P = 0.29）和 IV 级（P = 0.21）文章的比例保持不变，II 级（P < 0.01）和 III 级（P < 0.01）文章增加，而 V 级（P < 0.01）文章减少。美国作者的比例从 1994 年的 78.1%下降到 2009 年的 44.8%，然后在 2019 年保持不变（P < 0.01）。
结论
本研究表明，在三个高质量骨科期刊的 25 年期间，足踝文献的 LOE 得到了提高，同时也观察到国际化程度的提高。
