Abstract
Objective: Antibiotic-loaded bone cement (ALBC) plays an indispensable role in the treatment of infectious diseases of bone and joint. Here, we intended to analyze the research status, hot spots and frontiers in the field of ALBC, and to provide reference for future research ideas. Methods: The related English literature in the field of ALBC in the Web of Science Core Collection database was retrieved from January 1, 2009 to July 11, 2023. VOSviewer was used to extract the information of research constituents or bibliometric items such as authors, institutions, countries, and journals. CiteSpace was used to perform cluster analysis and frontier analysis of key words in ALBC research field. Results: (29 papers, 488 times cited). The keywords with high frequency were infection (266 times), vancomycin (239 times), bone-cement (219 times), gentamicin (216 times), antibiotics (168 times), osteomyelitis (163 times), etc. The clustering knowledge map of high-frequency keywords could be divided into 4 categories: (1) elution, release, mechanical and antibacterial properties of ALBC; (2) Application of ALBC in revision of prosthetic joint infections (PJIs); (3) Antibiotic types and application forms of ALBC; (4) Application of ALBC in the treatment of osteomyelitis. The keywords with the strongest citation bursts analysis revealed a core ("replacement/arthroplasty") and two stages of development in the field of ALBC research. The first stage (2009-2018) focused more on ALBC drug delivery, release, and infection prevention, while the second stage (2018-2023) mainly focused on ALBC drug elution, mechanical properties, and PJIs revision. Starting from 2018, the keyword with the strongest citation bursts had shifted from "acrylic bone cement" to "periprosthetic joint infection". Conclusion: ALBC research is steadily on the rise. Arthroplasty related applications continue to be the core of ALBC research. The research hotspot and trend are mainly the application in the prevention and treatment of bone and joint infectious diseases and the elution, release, mechanical and antibacterial properties of ALBC.
