PURPOSE: To evaluate the result of treatment of the infected total knee arthroplasty by two-stage revision using antibiotics-impregnated cement. MATERIALS AND METHODS: We observed 2 staged revision cases of 11 infected total knee arthroplasty from March 1988 and March 2001. Average follow-up was 39.4 (28-60) months. At the time of infection management, the average age was 64.0 years. Local inflammatory finding, WBC with differential count, erythrocyte sedimentation ratio, C-reactive protein, joint aspiration and intraoperative frozen section (x400) were used to diagnose infection. We assessed knee function according to the knee rating system of the Hospital for Special Surgery (HSS). RESULTS: Prior to revision, the average HSS score was 50.8 points, and the average range of motion was 73.4 degrees. At. final follow-up, the average HSS score was 79.1 points, and the average range of motion was 90.2 degrees. At the last follow up, there were no sign of recurrence of infection clinically and radiologically. CONCLUSION: At least 2 year follow up, the results of two-stage revision using antibiotics-impregnated cement were good.
