This study aimed to investigate the characteristics of research articles and research trends in computer-assisted orthopedic surgery (CAOS) by conducting bibliometric analyses.
CAOS-related research articles published in international journals from 2002 to 2021 were collected using the PubMed database and analyzed using the bibliometric method. Their publication year, journal name, corresponding author's country name, and the number of citations of all collected articles were noted. Contents of the articles were analyzed to evaluate the time point and anatomical site at which the digital technique was applied. Further, the 20-year period was divided into two halves of 10 years each to analyze the research trends.
A total of 639 CAOS-related articles were identified. An average of 32.0 CAOS-related articles were published annually, with an average of 20.6 and 43.3 published in the first half and second half, respectively. Of all articles, 47.6% were published in the top 10 journals, and 81.2% were written in the top 10 countries. The total numbers of citations were 11.7 and 6.3 in the first and second halves, respectively, but the average annual number of citations was higher in the second half than in the first one. Articles on application of digital techniques during surgery were 62.3% and those on pre-surgery application were 36.9%. Further, articles in the knee (39.0%), spine (28.5%), and hip and pelvis (21.5%) fields accounted for 89.0% of the total publications. But the increase in publications in the said period was highest in the fields of the hand and wrist (+1,300.0%), ankle (+466.7%), and shoulder (+366.7%).
Over the last 20 years, the publication of CAOS-related research articles in international journals has grown steadily. Although the knee, spine, hip, and pelvis fields account for most CAOS-related research, research in new fields is also increasing. This study analyzed the types of articles and trends in CAOS-related research and provided useful information for future research in the field of CAOS.
本研究旨在通过文献计量学分析，调查计算机辅助骨科手术（CAOS）研究论文的特点和研究趋势。
使用 PubMed 数据库收集 2002 年至 2021 年国际期刊发表的 CAOS 相关研究论文，并采用文献计量学方法进行分析。记录所有收集文章的发表年份、期刊名称、通讯作者所在国家名称和引用次数。分析文章内容，评估数字技术应用的时间点和解剖部位。此外，将 20 年分为两个 10 年的时间段，以分析研究趋势。
共确定了 639 篇 CAOS 相关文章。平均每年发表 32.0 篇 CAOS 相关文章，其中前 10 年发表 20.6 篇，后 10 年发表 43.3 篇。所有文章中，47.6%发表在排名前 10 的期刊上，81.2%来自排名前 10 的国家。前 10 年和后 10 年的总引用次数分别为 11.7 和 6.3，但后 10 年的平均年引用次数高于前 10 年。手术中应用数字技术的文章占 62.3%，术前应用的文章占 36.9%。此外，膝关节（39.0%）、脊柱（28.5%）和髋部及骨盆（21.5%）领域的文章占总出版物的 89.0%。但在所述期间，手部和腕部（+1300.0%）、踝关节（+466.7%）和肩部（+366.7%）领域的出版物增长率最高。
在过去的 20 年中，国际期刊上发表的 CAOS 相关研究论文数量稳步增长。尽管膝关节、脊柱、髋部和骨盆领域占据了大多数 CAOS 相关研究，但新领域的研究也在增加。本研究分析了 CAOS 相关研究论文的类型和趋势，为 CAOS 领域的未来研究提供了有用的信息。
