In this retrospective study, we compared forty-five patients who had undergone same-day bilateral total knee arthroplasties with 144 patients who had undergone unilateral total knee arthroplasty procedures. All procedures were performed by a single surgeon using a single prosthetic design between June 1994 to May 1996. The issues studied were the length of hospital stay, hospital charges, units of blood transfused, units of homologous blood transfused, and the rate and type of complications. This study also examined the usage and financial charges of extended care facilities and/or home health care following discharge from the hospital. Results show that, for patients suffering from symptomatic bilateral knee disease, the same-day bilateral total knee procedure is significantly less costly than staged bilateral procedures. The rate and type of complications seen in the same-day bilateral cases were not significantly different from complications seen in unilateral cases.
