Objectives: Bibliometric analysis is one of the most prevalent methods for analyzing and predicting the research trends of particular subjects. Through a bibliometric analysis, this study sought to look into and depict the hotspots and research trends in knee arthroplasty research over the previous five years.
Methods: The Web of Science Core Collection database was used to find research articles on knee arthroplasty published between 2018 and 2022. The VOS viewer, Cite Space, and Bibliometrix were used to carry out the bibliometric study and network visualization.
Results: During the previous five years, 7,422 included knee arthroplasty publications were cited 57,087 times. The United States and the Journal of Arthroplasty were the top countries and journals regarding the number of articles. The top 10 global high-impact documents were determined using the citation ranking and citation burst. The most frequently referenced article revealed that the epidemiological characteristics of knee arthroplasty, perioperative care in knee arthroplasty, prosthetic joint infections, and opioid medications were the hot topics in knee arthroplasty research. Keyword burst analysis showed that the research trends in knee arthroplasty through 2022 were racial disparity, limb alignment, tibial slope, and meniscectomy. The analysis of the subject areas revealed the close connections and relationships between different subject areas, as demonstrated by the figures.
Conclusion: The knee arthroplasty research community is highly productive and centralized. Recent hotspots in knee arthroplasty research were unicompartmental knee arthroplasty, periprosthetic joint infection, kinematic alignment, outpatient total knee arthroplasty (TKA), bariatric surgery, payment model, tranexamic acid, Robotic-Assisted TKA, patient-reported outcome measures, metaphyseal cone, opioid use, and patient-specific instrumentation. Research trends in knee arthroplasty research were racial disparity, limb alignment, tibial slope, and meniscectomy.
