This study concerns patients having had an infection on their prosthesis (hip, knee,..) and for whom a 2-step exchange of prosthesis has been done. A 2-step exchange consists in explantation of the prosthesis and implementation of a spacer at the first stage, and reimplantation of a new prosthesis in a second stage. Patients with late prosthetic joint infection are at risk for superinfection at the time of reimplantation. The aim is to determine the microbiological epidemiology in patients experiencing failure following reimplantation to establish, based on the drug susceptibilities, which cement could be the most active.
