Research interests and emerging trends of meniscal extrusion and the future of arthroscopic centralization: a bibliometric and visualized analysis in the last 20 years

Abstract

Abstract Background: Bibliometrics refers to measuring the scientific output of an author, institution, or country. Visualized analysis transforms data into visible form by software, allowing researchers to gain knowledge of significant aspects of their data easily and quickly. This study conducts a comprehensive bibliometric analysis of the literature on meniscal extrusion and arthroscopic centralization, while also incorporating trend visualization for enhanced insights. Methods:Web of Science (WOS) was chosen as the database for this evaluation. The search encompassed the period from January 1, 2002, to December 31, 2022, yielding 690 records after exclusion. The publications, citations, authors, keywords, countries, and institutions were subjected to analysis using VOSviewer and Citespace. Results:The number of publications progressively increases year by year. The United States and Japan emerge as the top two countries, with Boston University and Okayama University being the leading institutes. Guermazi Ali and Furumatsu Takayuki are the top two authors with the most publications. Among the journals, Knee surgery, sports traumatology, arthroscopy, Osteoarthritis and Cartilage exhibit the most substantial number of publications. Notably, there has been a recent focus on pullout repair, posterior root tear, meniscal extrusion, and meniscus centralization, attracting significant attention in the field. Conclusion:The results reveal that research related to meniscal extrusion and arthroscopic centralization predominantly originates from a limited number of corresponding authors and institutions. There is a strong interest in this topic within top-tier sports medicine journals and among developed countries. The focus of interest in this field has undergone dynamic shifts over time.
