Abstract
Periprosthetic infection after total joint replacement is a catastrophic complication. Current rates of infection have been decreasing and in most centers now are in the range of 0.1–1%. Peri-operative intravenous antibiotic therapy is used routinely in total hip arthroplasty patients at this time. With rates this low and mixed evidence that antibiotics in bone cement for routine total hip replacement are beneficial at reducing joint infection, routine use of this practice seems unnecessary and has potential disadvantages. Cost of antibiotics being added to cement on a routine basis will increase the cost of the arthroplasty $300–$500. Although small addition of bone cement also has a negative effect on the mechanical properties of the cement. The major disadvantage remains the danger of resistant bacterial strains from excessive use of antibiotics particularly vancomycin resistant organisms when it is used routinely. Although rare with the aminoglycosides, allergic reactions may occur if cephalosporins are used as prophylaxis. Use of antibiotics in bone cement should be considered in high risk patients for infection undergoing total hip replacement but not routinely because of cost, emergence of resistant organism and possible allergic reaction.
