Achilles tendon injuries represent one of the most common reasons for referral to orthopaedic surgeons.
To outline the characteristics, examine trends in publication, and evaluate the correlation between citations and study quality of the 50 most cited articles on Achilles tendon injury.
Cross-sectional study.
After searching the Web of Science for articles published in orthopaedic journals, we identified the 50 most cited articles on Achilles tendon injury and abstracted their characteristics. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). Multiple bivariate analyses (Pearson or Spearman correlation coefficient) were used to evaluate the association among number of citations, citation rate (citations/year), 2020 journal impact factor (JIF), year of publication, level of evidence (LoE), study type (tendon rupture or chronic tendinopathy), sample size, and mCMS.
The top 50 articles were cited 12,194 times. Each article had a mean ± SD 244 ± 88.8 citations (range, 157-657) and a citation rate of 12.6 ± 5.4 per year (range, 3-28). A total of 35 studies (70%) were published between 2000 and 2010. The citation rate of the 16 most recent studies was almost double that of the 16 oldest studies (17.5 vs 9.9; < .001). Nineteen studies (49%) were classified as having poor quality (mCMS <50 points). The mean JIF of the 9 journals that published the studies was 5.1. The citation rate correlated with the number of citations ( = 0.56; < .001), publication year ( = 0.60; < .001), and LoE ( = -0.44; = .005). The publication year correlated with the LoE ( = -0.40; = .01). Study quality in terms of mCMS correlated with the JIF ( = 0.35; = .03) and LoE ( = -0.48; = .003) but not the citation rate ( = .15).
The mean LoE and the citation rate of the most cited articles on Achilles tendon injury both significantly increased over time. Although the JIF was positively correlated with study quality, almost half of the studies had poor-quality methodology.
跟腱损伤是转诊至骨科医生的最常见原因之一。
概述关于跟腱损伤的被引用次数最多的50篇文章的特征，研究其发表趋势，并评估引用次数与研究质量之间的相关性。
横断面研究。
在科学网搜索骨科期刊上发表的文章后，我们确定了关于跟腱损伤的被引用次数最多的50篇文章，并提取了它们的特征。使用改良的科尔曼方法评分（mCMS）评估偏倚风险。采用多元双变量分析（Pearson或Spearman相关系数）来评估引用次数、引用率（引用次数/年）、2020年期刊影响因子（JIF）、发表年份、证据水平（LoE）、研究类型（肌腱断裂或慢性肌腱病）、样本量和mCMS之间的关联。
前50篇文章被引用了12194次。每篇文章的平均±标准差引用次数为244±88.8次（范围为157 - 657次），每年的引用率为12.6±5.4次（范围为3 - 28次）。共有35项研究（70%）在2000年至2010年期间发表。16项最新研究的引用率几乎是16项最旧研究的两倍（17.5对9.9；P <.001）。19项研究（49%）被归类为质量较差（mCMS <50分）。发表这些研究的9种期刊的平均JIF为5.1。引用率与引用次数（r = 0.56；P <.001）、发表年份（r = 0.60；P <.001）和证据水平（r = -0.44；P = 0.005）相关。发表年份与证据水平相关（r = -0.40；P = 0.01）。就mCMS而言，研究质量与JIF（r = 0.35；P = 0.03）和证据水平（r = -0.48；P = 0.003）相关，但与引用率无关（r = 0.15）。
关于跟腱损伤的被引用次数最多的文章的平均证据水平和引用率均随时间显著增加。尽管JIF与研究质量呈正相关，但几乎一半的研究方法质量较差。
