Treatment for Infected Total Knee Arthroplasty.

We treated five patients with five infected total knee arthroplasties for 10 years. We reviewed onset time of infection, organism, surgery for the affected knee, and timing of reimplantation. The average onset time was 23 months (range: 2 to 84 months). Cultures grew Staphylococcus epidermidis in three knees, Staphylococcus aureus in one knee, and Klebsiella pneumoniae in one knee. Only one joint was cured by continuous drainage. Knee arthrodesis was conducted on one joint, and 2-stage reimplantation on three joints. But one joint was resulted in knee arthrodesis. The average timing of reimplantation was 5.6 months (range: 4 to 8 months).
