Abstract
Concentrations of cefuroxime were measured in the serum and femoral and tibial bone of 12 patients undergoing knee arthroplasty, following cefuroxime 1.5 g iv. The mean serum cefuroxime concentration was 112.4 mg/l at the time of application of the mid thigh tourniquet. The mean femoral bone concentration was 18.6 mg/kg and tibial bone was 15.5 mg/kg. These concentrations of cefuroxime appear adequate for prophylaxis against post-operative infection in knee arthroplasty.
