Two-stage Reimplantation in Infected Total Knee Arthroplasty Using a Re-sterilized Tibial Polyethylene Insert and Femoral Component

초록

Infection in total knee arthroplasty (TKA) is a challenging complication. We reviewed 20 cases of infected TKAs treated by two-stage reimplantation procedure involving the use of a temporary articulating system composed of autoclaved femoral component, low temperature hydrogen peroxide gas plasma sterilized polyethylene insert, and antibiotic-impregnated bone cement. The knee and functional score of the Knee Society scoring system at the last follow (average, 64.8 months) up was 86.2 points and 78.8 points. The success rate in terms of eradication of infection was 95% (19/20 knees). Use of a temporary articulating system composed of the re-sterilized components with antibiotic-impregnated bone cement was an effective therapy not only for the eradication of the infection but also for the recovery of soft tissue health and knee function.
