前交叉韧带重建国际研究现状及趋势的可视化分析

Visualization of global status and trends in anterior cruciate ligament reconstruction

背景:前交叉韧带损伤是膝关节最常见的损伤之一,对前交叉韧带重建相关研究进行文献计量学及可视化分析,可以帮助理清这一领域的研究历程,快速了解现有研究热点,合理预估未来的研究趋势,能够推动该领域的进一步发展。目的:分析前交叉韧带重建的全球研究现状及热点、未来发展趋势。方法:选用Web of Science科学引文索引的扩展数据库检索1995至2019年所有与前交叉韧带重建相关的文献出版物,用citespace软件对所有文献进行聚类、共现、突现词等分析。结果与结论:①共纳入9020篇英文文献,涉及20566位作者,55个国家和地区,6117个研究机构,690个出版物来源;全球发文量大体呈逐年波动式增长趋势,2019年发文量达到最高的866篇;②美国在前交叉韧带重建相关领域研究占有绝对优势,发文量及H指数均排名第一;中国总发文量排名第4,H指数排名第11;③前交叉韧带重建相关研究关键词聚类分析显示最大的5个聚类为康复治疗、自体移植、患病率、恢复运动和损伤;2014至2019年突现的关键词有结果、运动、回归、风险、前外侧韧带和翻修;④文献共被引分析示被引频次前5名的文献均发表于2010至2014年,且其中有3篇与运动恢复相关,排名前5名的聚类为长期、单束、挤压螺钉、危险因素和回归;⑤提示移植物及内固定装置的选择以及术后康复治疗是目前主要的研究热点;通过康复治疗尽快恢复患者日常运动活动、术后韧带二次损伤的预防、合理处理术后并发症、韧带翻修等主题将成为未来有关前交叉韧带重建新的研究热点;中国在该领域发表的文献质量及国际合作方面有待加强。

BACKGROUND:Anterior cruciate ligament injury is one of the most common injuries of the knee joint.Bibliometrics and visual analysis of related research on anterior cruciate ligament reconstruction can help clarify the research process in this field and quickly understand the current research hotspots.A reasonable estimate of future research trends can promote the further development of this field.OBJECTIVE:To analyze the global research status,hot spots and future development trends of anterior cruciate ligament reconstruction.METHODS:Web of Science Core Collection was retrieved for publications related to anterior cruciate ligament reconstruction published from 1995 to 2019.Citespace software was used to analyze the cluster,co-occurrence and burst words of the included literatures.RESULTS AND CONCLUSION:A total of 9020 articles in English were included,involving 20566 authors,55 countries and regions,6117 research institutes,and 690 publication sources.The global publication volume showed a trend of fluctuating increase year by year,and reached a peak of 866 articles in 2019.The United States has an absolute advantage in the research of anterior cruciate ligament reconstruction,ranking first in terms of publication volume and H index.China ranks 4th in total publications and 11th in the H index.Top five clusters of key words in anterior cruciate ligament reconstruction research included rehabilitation,autograft,prevalence,return to sport,and injury.Burst words highlighted from 2014 to 2019 included:outcome,sports,return,risk,anterolateral ligament,and revision.The co-citation analysis of references showed that the top five literatures with highest citation frequency were all published between 2010 and 2014,three of which are related to sport recovery.The top five clusters included long term,single bundle,interference screw,risk factor and return.In conclusion,the selection of grafts and internal fixators and postoperative rehabilitation are the main research hotspots at present.The topics such as return to sport as soon as possible through rehabilitation treatment,prevention of postoperative ligament secondary injury,reasonable treatment of postoperative complications,and ligament revision will become new research hotspots in the future related to anterior cruciate ligament reconstruction.The quality of China’s publications and international cooperation in this field need to be strengthened.
