Cefuroxime-impregnated cement and systemic cefazolin for 1 week in primary total knee arthroplasty: An evaluation of 2700 knees

BackgroundInfection is one of the most devastating complications after primary total knee arthroplasty (TKA). Antibiotics-impregnated cement has been used and proven effective in preventing deep infection. This study was to evaluate the long-term results of using cefuroxime-impregnated cement and systemic cefazolin for one week to assess their efficacy in preventing infection of primary TKA.MethodsFrom 1999 to 2007, 2700 cases of primary TKA were performed with cemented fixation of all patellar, tibial, and femoral components. Cefuroxime-impregnated cement for fixation and systemic cefazolin for one week were selected in all cases. The average follow-up period was 89 months (range, 40–140). The effects of this selected regime in the periprosthetic infection were evaluated.ResultsA total of eight infections occurred after primary TKA, including five deep infections (0.19%) and three superficial infections (0.11%) in the 2700 knees. No loosening or osteolysis was noted.ConclusionComparable with other measurements, cefuroxime-impregnated cement, accompany by systemic cefazolin for 1 week was shown to control postoperative deep infection to 0.19% (after primary TKA was performed in an operative setting without lamina flow and body exhaust suit).
