Definition of periprosthetic joint infection and fracture-related infection

Diagnosis of bone and joint infections can be difficult. In recent years there has been great progress in defining how we diagnose fracture-related infection (FRI) and prosthetic joint infection (PJI). Definitions have been proposed based on the best evidence from the literature, including well-established tests performed before and during surgery. These allow surgeons to make better decisions for treatment and to counsel patients. This paper presents the elements of the International Consensus Definition of FRI and the European Bone & Joint Infection Society Definition of Prosthetic Joint Infection (PJI), together with the current knowledge on how these definitions can help in clinical practice.
