Background: It’s always a burning debate, whether a simultaneous or staged bilateral Total Hip Arthroplasty (THA) should be performed for patients with painful disabling bilateral hip diseases. Although, many studies now indicate that the treatment option should be patient specific to achieve the maximum efficiency without increasing risk of perioperative complications. The purpose of this study to compare simultaneous vs staged procedure in order to determine the functional outcomes, risks and benefits of each procedure.

Materials and Methods: Our study includes total 80 patients (160 hips) with advanced bilateral hip diseases, underwent simultaneous or staged bilateral THA during 2015 to 2019. Study population was randomly divided into two groups with 40 patients in each one. The post-op evaluations were done according to Harris Hip Score (HHS) at one, three, six and 12 months and yearly thereafter for 2 years. The second procedure in staged group was done at 6 weeks to 3 months interval. All possible outcomes and complications regarding each procedure were accessed.

Results: As compared to staged procedure, estimated blood loss was significantly less in simultaneous THA (group A). Although, requirement of blood transfusion was significantly higher in this group. The length of hospital stay was significantly shorter in group A. Although, overall complication rate was higher in group A but it was statistically not significant. Superficial surgical site infection was significantly lower in simultaneous THA group. There was no post-op dislocation, no in-patient mortality and no need of revise the surgery in any of our study group within 2 years of follow-up.

Conclusion: With proper patient selection, simultaneous bilateral THA is safe, effective and good alternative to staged procedure for painful disabling bilateral hip diseases.
