One- or two-stage bilateral total hip replacement.

Journal article

It is not clear whether bilateral hip replacement should be done in 1 or 2 stages. The total number of total hip replacements (THRs) done in our center between 1989 and 1995 was approximately 4,000. The number of hips that were bilateral was 404, or 9% of the total number of THRs performed during this time period. Of these bilateral hip replacements, 190 (95 patients) were done as a 1-stage procedure, whereas 214 (107 patients) were done in 2 stages with 2 to 24 months in between the operations. In contrast to previous studies, there were no significant preoperative differences between the 2 groups of patients having 1-stage or 2-stage THRs, and, in particular, the comorbidity assessed by the American Society of Anesthesiologists (ASA) grade was not significantly different. Our results demonstrate that, in our patient population, bilateral THR was equally safe whether performed as a 1-stage or 2-stage procedure. This was the case in the low-risk (ASA 1 and 2) and high-risk (ASA 3 and 4) patient subgroups. One-stage bilateral THR is cheaper and involves less time in the hospital.
