Enterococcal Prosthetic Joint Infection Treated With Prosthesis Retention: A Case Report

Abstract

Periprosthetic joint infection may occur after prosthetic joint replacement. Treatment usually requires removal of the prosthesis in addition to systemic antibiotics. We report a case of enterococcal prosthetic knee infection that was treated with arthroscopic lavage and intravenous antibiotics (ampicillin 2 g every 4 h for 6 weeks and gentamicin 80 mg every 8 h for 2 weeks) with retention of the prosthesis. Upon discharge, the patient was placed on oral amoxicillin 1g twice daily for a duration of 2 years. The patient now has been off antibiotics for 3 years, and is showing no signs of recurrence of his infection on his last follow-up.
