Recent Trends and Hotspots in Hip Arthroplasty: A Bibliometric Analysis and Visualization Study of Last Five-Year Publications

Objectives: Bibliometric analysis is one of the most prevalent methods for analyzing and predicting research trends of particular subjects. Through a bibliometric analysis, the present study sought to look into and depict the hotspots and research trends in hip arthroplasty research over the previous five years.

Methods: The Web of Science Core Collection database was used to find studies on hip 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 last five years, 5,708 hip arthroplasty publications were cited 40,765 times. The United States and the Journal of Arthroplasty were the top countries and journals regarding the number of studies, respectively. The top 10 global high-impact documents were determined using the citation ranking and citation burst. The most frequently referenced research revealed the epidemiological aspects of hip arthroplasty, perioperative care after hip arthroplasty, COVID-19, periprosthetic joint infections, opioid medicines, stability, and osteonecrosis were the hot topics in hip arthroplasty research. Keyword burst analysis showed that the research trends in hip arthroplasty through 2022 were patient-reported outcome measures (PROM), depression, racial disparity, and artificial intelligence (AI). The analysis of the subject areas revealed the close connections and relationships between different subject areas, as demonstrated by the figures.

Conclusion: The hip arthroplasty research community is very productive and highly centralized. Periprosthetic joint infection, dual-mobility cups, spinopelvic mobility, direct anterior approach, outpatient total hip arthroplasty, polyethylene, periprosthetic fracture, acetabular defects, tranexamic acid, developmental dysplasia of the hip, and safety-net hospitals were recent trends in hip arthroplasty research. Patient-reported outcome measures, depression, racial disparities, and AI were research hotspots in hip arthroplasty.
