Abstract

Forty patients underwent 80 bilateral primary total hip replacements (THRs) under the same anesthesia (one-stage). Forty other patients who underwent unilateral primary THRs during the same time interval were selected to match the first 40 patients with regard to age, sex, diagnosis, weight, medical comorbidity, type of prosthesis used, and perioperative management protocol. An assumption was made in that each unilateral case represented the first side of bilateral THRs performed during two separate hospitalizations (two-stage). Analysis of the total hospital charges submitted to the insurance companies was made between the groups. On average, there was a 24% reduction (P<.05) for each case if bilateral THRs were done in one stage. This was primarily due to a significant decrease (P<.05) in the length of hospital stay in the one-stage group. There was no difference between the two groups in the operative time, estimated blood loss, or perioperative complications.
