Objective:
This study employs bibliometric and visualization analysis to systematically investigate research hotspots and emerging trends in the biomechanics of knee osteoarthritis (KOA).
Methods:
This study utilizes the Web of Science Core Collection (WoSCC) as the data source, employing a keyword-based search strategy to retrieve literature on the biomechanics of KOA published over the past two decades. Bibliometric analyses are conducted using tools such as CiteSpace and VOSviewer.
Results:
A total of 1932 articles were included in the analysis. Research outputs from the United States have been particularly prominent, setting a benchmark for the global academic community. Institutions such as the University of Melbourne and Stanford University have exhibited notable academic leadership. Professors Bennell KL and Andriacchi TP, identified as highly productive authors, have been frequently cited. Journals including Gait Posture and Osteoarthr Cartilage have served as key platforms for knowledge dissemination and academic dialogue. Current research foci are centered on keywords such as total knee arthroplasty, outcomes, injury, baseline, exercise, meniscus, MRI, risk, and knee adduction moment (KAM). These themes reflect contemporary research activity and suggest emerging frontiers. As biomechanical investigations deepen, the pathogenesis of KOA is anticipated to be more fully understood, offering a robust scientific foundation for clinical practice.
Conclusions:
This study employs bibliometrics and visualization analysis to conduct a comprehensive examination of hotspot issues and frontier trends in the biomechanics of KOA, offering researchers a structured understanding of research trajectories and trend insights.
