Prosthesis Infection and One-step Exchange: Pretreatment by Targeted Antibiotic Therapy in At-risk Patients

Completed

• Conditions: Prosthetic Joint Infection; Antibiotic Resistant Infection
• Interventions: Other: Antibiotic pretreatment

• Registration Number: NCT03848091
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

One-step exchange arthroplasty is more and more used in the treatment of chronic infections, especially in patients at risk anesthetic.

This strategy is not recommended in patients infected with multidrug-resistant organisms or difficult to treat because of a risk of bacterial persistence on the new implant.

Antibiotic pretreatment by a narrow-spectrum molecule and for which resistance acquisition is difficult might be of interest to try to reduce the inoculum and avoid contamination of the new implant.
