This study aimed to evaluate both publication and authorship characteristics in Knee Surgery, Sports Traumatology, Arthroscopy journal (KSSTA) regarding knee arthroplasty over the past 15 years.
PubMed was searched for articles published in KSSTA between January 1, 2006, and December 31st, 2020, utilising the search term 'knee arthroplasty'. 1288 articles met the inclusion criteria. The articles were evaluated using the following criteria: type of article, type of study, main topic and special topic, use of patient-reported outcome scores, number of references and citations, level of evidence (LOE), number of authors, gender of the first author and continent of origin. Three time intervals were compared: 2006-2010, 2011-2015 and 2016-2020.
Between 2016 and 2020, publications peaked at 670 articles (52%) compared with 465 (36%) published between 2011 and 2016 and 153 articles (12%) between 2006 and 2010. While percentage of reviews (2006-2010: 0% vs. 2011-2015: 5% vs. 2016-2020: 5%) and meta-analyses (1% vs. 6% vs. 5%) increased, fewer case reports were published (13% vs. 3% vs. 1%) (p < 0.001). Interest in navigation and computer-assisted surgery decreased, whereas interest in perioperative management, robotic and individualized surgery increased over time (p < 0.001). There was an increasing number of references [26 (2-73) vs. 30 (2-158) vs. 31 (1-143), p < 0.001] while number of citations decreased [30 (0-188) vs. 22 (0-264) vs. 6 (0-106), p < 0.001]. LOE showed no significant changes (p = 0.439). The number of authors increased between each time interval (p < 0.001), while the percentage of female authors was comparable between first and last interval (p = 0.252). Europe published significantly fewer articles over time (56% vs. 47% vs. 52%), whereas the number of articles from Asia increased (35% vs. 45% vs. 37%, p = 0.005).
Increasing interest in the field of knee arthroplasty-related surgery arose within the last 15 years in KSSTA. The investigated topics showed a significant trend towards the latest techniques at each time interval. With rising number of authors, the part of female first authors also increased-but not significantly. Furthermore, publishing characteristics showed an increasing number of publications from Asia and a slightly decreasing number in Europe.

本研究旨在评估过去 15 年中《膝关节外科、运动创伤学与关节镜》（KSSTA）杂志在膝关节置换方面的出版和作者特征。
利用搜索词“膝关节置换”，在 PubMed 上检索 2006 年 1 月 1 日至 2020 年 12 月 31 日期间发表在 KSSTA 上的文章。共纳入 1288 篇文章。使用以下标准评估文章：文章类型、研究类型、主要主题和特殊主题、使用患者报告的结果评分、参考文献和引文数量、证据水平（LOE）、作者数量、第一作者的性别和原籍大陆。比较了三个时间段：2006-2010 年、2011-2015 年和 2016-2020 年。
与 2011-2016 年（465 篇，占 36%）和 2006-2010 年（153 篇，占 12%）相比，2016-2020 年发表的文章数量达到峰值，为 670 篇（占 52%）。综述的比例（2006-2010 年：0%比 2011-2015 年：5%比 2016-2020 年：5%）和荟萃分析的比例（1%比 6%比 5%）增加，而病例报告的数量减少（13%比 3%比 1%）（p<0.001）。对导航和计算机辅助手术的兴趣减少，而对围手术期管理、机器人和个体化手术的兴趣增加（p<0.001）。参考文献数量增加[26（2-73）比 30（2-158）比 31（1-143），p<0.001]，而引文数量减少[30（0-188）比 22（0-264）比 6（0-106），p<0.001]。LOE 没有显著变化（p=0.439）。作者数量在每个时间段都有所增加（p<0.001），而第一作者和最后一个时间段的女性作者比例相当（p=0.252）。欧洲发表的文章数量随时间减少（56%比 47%比 52%），而亚洲发表的文章数量增加（35%比 45%比 37%）（p=0.005）。
在过去的 15 年中，KSSTA 对膝关节置换相关手术领域的兴趣不断增加。在每个时间间隔，研究的主题都明显倾向于最新技术。随着作者数量的增加，女性第一作者的比例也有所增加-但不显著。此外，出版特征显示来自亚洲的出版物数量增加，而来自欧洲的出版物数量略有减少。
