Intravenous antibiotics effectively reduce the prevalence of postoperative infection. However, Japanese orthopaedic surgeons have no consensus with regard to the optimal duration of prophylaxis. The aim of this study is to compare the outcome of one-day intravenous antibiotic administration with that of long-term intravenous antibiotic administration. Patients who underwent total hip or knee arthroplasty were divided into 2 groups to receive one of 2 prophylactic protocols retrospectively. Group A (223 patients) received intravenous antibiotics twice only on the day of surgery, whereas Group B (104 patients) received intravenous antibiotics for at least 3 days after surgery. We analyzed the wound infection rate and monitored liver and renal functions. None of these patients had a postoperative infection. No liver dysfunction and renal dysfunction were observed. One-day antibiotic infusion was as effective as long-term antibiotics in preventing infection after arthroplasty and achieved greater cost effectiveness.
