To provide proof of concept in an in vivo animal model for the prevention of prosthetic joint infection prevention using electric fields along with conventional antibiotic prophylaxis. Corresponding Author: Marti Bernaus First, we standardized the animal model to simulate implant contamination during the surgical procedure. We then implanted cobalt-chrome prostheses adapted to both knees of two New Zealand White rabbits, under standard aseptic measures and antibiotic prophylaxis with cefazolin. Prior to implantation, we immersed the prostheses in a 0.3 McFarland inoculum of Aim
Method
To evaluate the efficiency of pulse lavage combined with electrical fields to remove biofilm from a metallic surface. Using a 12-well culture plate designed for the application of electrical fields, strains of After exposure, each bottom electrode was scraped carefully to release adhered bacteria. Subsequently, different dilutions of biofilm removed were spread onto Müller Hinton agar plates and incubated for 24h at 37 ºC, and colony-forming units (CFU) per milliliters were counted. Bacterial counts were then compared to the control model.Aim
