Bioavailability of gentamicin and vancomycin released from an antibiotic containing bone cement in patients undergoing a septic one-stage total hip arthroplasty (THA) revision: a monocentric open clinical trial.

Background: The purpose of this clinical investigation was to evaluate the systemic bioavailability of antibiotics from bone cement after implantation. This was done by determining the concentrations of gentamicin and vancomycin in plasma and urine of patients receiving a novel bone cement during one-stage revision in periprosthetic hip infections. The local concentrations of both antibiotic agents in wound exudate as well as the efficacy and tolerability were assessed as a secondary objective.
