Answer

First, remove the prosthesis and follow with 6 weeks of antibiotic therapy. Then, place the new joint, impregnating the methylmethacrylate cement with an anti-infective agent (ie, gentamicin, tobramycin). Antibiotic diffusion into the surrounding tissues is the goal. The success rate for this approach is approximately 95% for both hip and knee joints.
