Purpose : To compare the postoperative complications and cost-effectiveness of simultaneous and staged bilateral total hip arthroplasty (THA), using a minimally invasive two-incision technique.
Materials and Methods : All 206 patients who underwent simultaneous or staged bilateral THA using a modified, minimally invasive two-incision between January 2004 and November 2009 were registered and divided into a simultaneous bilateral THA group (group A, 147 patients) and staged bilateral THA group (group B: 59 patients). Staged THA was performed on group B with interval of at least 2 months between the initial and second surgery. Clinical evaluations, amount of blood loss, need for transfusion, complications and costeffectiveness were compared.
Results : Perioperative morbidity rates were similar in the two groups (P=0.546) and overall complications were not significant between the groups. Average length of hospital stay was significantly shorter in group A than in group B (average 14.6 days vs. 25.3 days; P<0.001). Total medical cost was significantly higher in group B than in group A (average 9,236 US dollars vs. 11,163 US dollars). Patients in group A required more blood transfusions than those in group B (3.02 vs. 1.90 units; P=0.003), although blood loss in the two groups were similar (892 vs. 917 ml P=0.613).
Conclusion : Comparison of intra- and postoperative complications support the conclusion that simultaneous bilateral THA compares favorably with staged THA in terms of outcomes, complications and cost-effectiveness.
