Participants after first-stage of knee infection reimplantation will be assign to one of two groups: with stem vs. with sleeve. Investigators will check participants on clinical, laboratory and reinfection signs. The main hypothesis is that better mechanical stability of endoprosthesis with sleeves will support infection treatment.
