Brief Summary:
Total knee arthroplasty (TKA) infection is a complication requiring multiple hospitalizations, operations, and outpatient visits placing a significant burden on both patient and treating surgeons. When revision surgery is needed, two kinds of treatment can be applied----one-stage and two-stage reimplantation procedure. The two-stage reimplantation procedure is considered the gold standard for treatment of subacute and chronic deep periprosthetic infections. Placement of antibiotic-loaded spacer is a standard procedure for eradication of peri-prosthetic joint infection. For better patient outcome, the purpose of this study was to determine the success rate of total knee infection patients treating with two-stage reimplantation procedure.
