As the body's first line of defense, neutrophils play an important role in the early stages of infection. Neutrophil extracellular traps (NETs), a novel way to kill pathogens, are released from activated neutrophils to trap and kill microorganisms and protect the body from invasion. However, studies have shown that NETs not only play a role in self-defense in vivo but also participate in some pathological processes. Current studies have found that excessive or abnormally activated NETs play a pathogenic role in a variety of diseases. NETs, in addition to killing pathogens during the pathology of sepsis, affect on coagulation function, and blood endothelium. Additionally, NETs have a wide range of effects in other inflammatory, immune, and other related diseases. NETs are involved in the pathology of atherosclerosis. NETs also play a role in systemic lupus erythematosus, diabetes mellitus, Alzheimer's disease, and tumors, but there are relatively few NETs studies on bone and joint diseases. This article discusses NETs, their formation, and their association with bone and joint disorders. New targets for the effective treatment of joint diseases may be identified by studying the relationship between NETs and bone and joint diseases.
