    Simultaneous bilateral total hip arthroplasty offers comparable postoperative complication rates to unilateral procedures. This approach provides a 30% cost saving, with only slightly longer hospital stays and convalescence.

    Area of Science:

    • Orthopedic Surgery
    • Reconstructive Surgery

    Background:

    • Bilateral hip disease often requires total hip arthroplasty.
    • Simultaneous bilateral total hip arthroplasty (SBTHA) is an alternative to staged procedures.

    Purpose of the Study:

    • To compare the outcomes of SBTHA with unilateral total hip arthroplasty (THA).
    • To evaluate complications, functional outcomes, and costs associated with SBTHA.

    Main Methods:

    • Retrospective comparison of 196 patients undergoing SBTHA (392 hips) versus 427 patients undergoing unilateral THA (427 hips).
    • Analysis included operative time, blood loss, postoperative complications, hospital stay, costs, and functional outcomes at follow-up.
    • Statistical analyses employed multiple regression and analysis of covariance.

    Main Results:

    • SBTHA had longer operative times (3 hours vs. 1.25 hours) and greater blood loss (3 units vs. 0.5 units) compared to unilateral THA.
    • Postoperative complication rates (phlebitis, pulmonary emboli, dislocation, non-union, infection, loosening) were similar between groups.
    • Ectopic ossification was higher in the SBTHA group (36% vs. 25%, p < 0.008).
    • Functional outcomes, pain, and abduction status were comparable, but range of motion was better in the unilateral group.
    • SBTHA resulted in a 30% cost saving ($5,780 vs. $4,137 per hip equivalent).

    Conclusions:

    • SBTHA is a safe and cost-effective option for patients with bilateral hip disease.
    • Postoperative complications are similar to unilateral THA, with only minor differences in range of motion.
    • The procedure offers significant cost savings and comparable functional outcomes.
