The results found in the literature do not allow to define objectively the indications respective for a one-step or a two-step exchange of prosthetic joint. Some criteria could help to decide for one-step exchange or two-step exchange: bacteria is/are identified, profile of the bacteria, anesthetic difficulties,.. A puncture could allow to identify the bacteria involved in the prosthetic joint infection (PJI) and an antibiotherapy for a few days can be given to the patient in order to decrease the inoculum. Then, a one-step exchange can be performed. The purpose of this study is to describe the management of patients who had a pre-treatment before a one-step exchange of their prosthetic joint.

bacterial epidemiology
This outcome will describe the bacterial epidemiology identified with a punction, the antibiotherapy used for pre-treatment, the characteristics of patients and the PJI.
Time frame: at the end of follow-up (usually between 12 and 24 months after antibiotic therapy disruption)
Treatment failure
Treatment failure is defined by local clinical and/or microbiological relapse; and/or need for additional surgery; death of septic origin
Time frame: at the end of follow-up (usually between 12 and 24 months after antibiotic therapy disruption)
