Periprosthetic Joint Infection (PJI)-Results of One-Stage Revision with Antibiotic-Impregnated Cancellous Allograft Bone-A Retrospective Cohort Study.

Controversy exists regarding the optimal treatment of periprosthetic joint infection (PJI), considering control of infection, functional results as well as quality of life. Difficulties in treatment derive from the formation of biofilms within a few days after infection. Biofilms are tolerant to systemically applied antibiotics, requiring extreme concentrations for a prolonged period.
