Sifeng Shi, Weiran Shi, Bing Zhou, Shang Qiu Department of Orthopedic Surgery, the Affiliated Hospital of Xuzhou Medical University, Xuzhou, People’s Republic of ChinaCorrespondence: Sifeng Shi, Email [email protected]; Shang Qiu, Email [email protected]: Orthopedic infection is one of the most intractable orthopedic problems. Bacteria resistant to antibiotics also develop gradually. Chitosan is widely used in the Biomedical field because of its high biocompatibility, biodegradability, and antibacterial activity. Chitosan-based drug delivery systems are frequently utilized to produce controlled medication release. When combined with antibiotics, synergistic antibacterial effects can be achieved. Chitosan-based nanoparticles are one of the most widely used applications in drug delivery systems. The focus of this review is to provide information on new methods being developed for chitosan-based nanoparticles in the field of bone infection treatment, including chitosan nanoparticles for antibacterial purposes, Ch-loaded with antibiotics, Ch-loaded with metal, and used as immune adjuvants. It may Provide ideas for the fundamental research and the prospects of future clinical applications of orthopedic infections.Keywords: chitosan nanoparticles, orthopedic infection, chitosan-based nanoparticles, staphylococcus aureus
