Two-stage Arthroplasty for the Septic Arthritis of the Native Knee Joint

Briefly, investigators completely debrided all necrotic soft tissue in the first stage of the operation. The surgical site was flushed twice with hydrogen peroxide, iodine, and saline solutions. Then, the antibiotic-loaded cement spacer was inserted. After surgery, a 10-day course of intravenous organism-specific antibiotics or vancomycin was administered, followed by oral antibiotic therapy. Second-stage reimplantation was performed once there was no sign of infection. The spacer was removed and the new prosthesis was implanted without the use of antibiotic-containing bone cement.
