The aim of this retrospective observational study was to describe the epidemiology of Neisseria gonorrhoeae septic arthritis over the last 10 years at Brest and Rennes university hospitals. The main question is whether there are any risk factors based on the epidemiological and clinical data on these cases. The second objective is to characterize the gonococcal strains isolated in order to determine whether there is a common clone, a virulence factor or specific resistance genes.
