Two-Stage Arthroplasty Using Functional Temporary Prosthesis to Treat Infected Arthroplasty and Septic Arthritis of the Hip

Two-stage revision arthroplasty is the gold standard for treatment of infection after total hip Arthroplasty and end stage septic arthritis of the hip. In the first stage we used a modified technique to insert an inexpensive modular femoral component coated with antibiotic-impregnated polymethylmethacrylate articulating with a polyethylene liner. The construct was used in 8 patients with infected arthroplasty, and 6 patients with septic arthritis of the hip. Two patients were excluded (no second stage). Of the remaining 12 patients, only one patient had persistent infection after the first stage; 11 patients received a successful re-implantation at the second-stage. The technique provide a construct that can be used safely and successfully in the awaiting period between the two stages of revision arthroplasty.
