    Simultaneous bilateral total knee arthroplasties offer comparable pain relief and function restoration to staged procedures for rheumatoid arthritis and osteoarthritis. Staged surgeries significantly increase costs without improving patient outcomes.

    Area of Science:

    • Orthopedic Surgery
    • Rheumatology

    Background:

    • Severe rheumatoid arthritis and osteoarthritis often necessitate bilateral total knee arthroplasties.
    • The choice between simultaneous bilateral and staged procedures impacts patient management and healthcare costs.

    Purpose of the Study:

    • To compare the clinical outcomes and costs of simultaneous bilateral versus staged total knee arthroplasties.
    • To evaluate pain relief and functional restoration in patients undergoing these procedures.

    Main Methods:

    • Twenty-six patients with severe rheumatoid arthritis and osteoarthritis underwent bilateral total knee arthroplasties.
    • Patients were divided into two groups: 12 with simultaneous bilateral operations and 14 with staged procedures.

    Main Results:

    Related Experiment Videos

    • Both simultaneous and staged procedures yielded statistically comparable improvements in pain relief and overall function.
    • No intraoperative complications were reported, and postoperative morbidity was minimal and similar between groups.
    • Staged procedures were associated with substantially increased costs.

    Conclusions:

    • Simultaneous bilateral total knee arthroplasties are a cost-effective alternative to staged procedures for selected patients.
    • The surgical approach does not significantly alter clinical outcomes in terms of pain and function restoration.
