To examine a series of papers from top ranked orthopaedic journals with respect to the number of citations over a 10-year observation period to identify factors that lead to high citation rates.
The Web of Science database was consulted to identify all published papers from the first-year term of 2010 (January-May) from four top orthopaedic journals: AJSM, Arthroscopy, JBJS Am and KSSTA. The database was used to analyze and compare the papers with respect to their characteristics and citations up to 2019. Basic information for each paper was collected including the author, country, study type and average citations per year (ACY). The most (Top20%) and least (Bottom20%) frequently cited papers were identified and differences were extracted.
Five hundred sixteen papers were included with a total of 19,261 citations. Most of the published papers were from the United States (n = 245). On average, a paper received 37.3 citations over the 10-year observation period. The most cited paper was cited 322 times. The most cited study type was randomized controlled trial (RCT) (Ø80.8). The Top20% papers were cited 37 times more often than the Bottom20%. Among the Top20%, the largest group was cohort study (n = 20) followed by case series (n = 19). Among others, the number of authors, the number of keywords and the number of references significantly correlated with the number of citations (p < 0.001).
Factors influencing citation frequency were identified.
研究一系列来自顶级骨科期刊的论文在10年观察期内的被引用次数，以确定导致高引用率的因素。
查阅科学网数据库，以确定2010年第一学期（1月至5月）发表在四种顶级骨科期刊上的所有论文：《美国运动医学杂志》（AJSM）、《关节镜杂志》、《美国骨与关节外科杂志》（JBJS Am）和《韩国骨与关节外科学会杂志》（KSSTA）。利用该数据库分析和比较这些论文截至2019年的特征和被引用情况。收集每篇论文的基本信息，包括作者、国家、研究类型和每年平均被引用次数（ACY）。确定引用次数最多（前20%）和最少（后20%）的论文，并提取差异。
纳入516篇论文，共被引用19261次。大多数发表的论文来自美国（n = 245）。在10年观察期内，一篇论文平均被引用37.3次。被引用次数最多的论文被引用了322次。被引用次数最多的研究类型是随机对照试验（RCT）（Ø80.8）。前20%的论文被引用的频率比后20%的论文高37倍。在前20%的论文中，最大的一组是队列研究（n = 20），其次是病例系列（n = 19）。此外，作者数量、关键词数量和参考文献数量与被引用次数显著相关（p < 0.001）。
确定了影响引用频率的因素。
