title: Simultaneous bilateral versus unilateral total hip arthroplasty an outcomes analysis.
abstract: This study compared the morbidity, mortality, and outcomes of 900 simultaneous bilateral total hip arthroplasties in 450 patients and 450 unilateral total hip arthroplasties. Pulmonary complications were significantly higher in the simultaneous bilateral group (1.6% vs 0.7%; P < .0312). Fourteen (3.1%) patients in the simultaneous bilateral group and 18 (4%) patients in the unilateral group died within the first postoperative year. Patients with mortality in the first postoperative year were significantly older (69.8 vs 62.3 years; P < .0012). Long-term patient survival, the prosthetic survival, and functional outcomes were not significantly different between groups. Simultaneous bilateral total hip arthroplasty has advantages where both hips are symptomatic and has less risk in younger patients with understanding of the increased risk of pulmonary complications.
