    One-stage bilateral knee arthroplasty offers identical clinical outcomes to staged procedures. However, staged surgeries show a higher risk of thromboembolism and pulmonary embolism, making one-stage preferable for severe knee arthritis.

    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering

    Background:

    • Posterior stabilized condylar knee arthroplasty is a common procedure for severe knee arthritis.
    • Comparing unilateral, bilateral one-stage, and bilateral staged arthroplasty is crucial for optimizing patient outcomes and surgical approaches.

    Observation:

    • A study analyzed 304 posterior stabilized condylar knee arthroplasties over 2.5 years.
    • Clinical follow-up extended to a minimum of two years for all patients.
    • The Hospital for Special Surgery rating system was used to evaluate clinical results.

    Findings:

    • Clinical outcomes were equivalent across unilateral, bilateral one-stage, and bilateral staged arthroplasty groups.
    • Medical complications were similar, with a notable exception: staged procedures had a higher incidence of venographically confirmed thromboembolism and pulmonary embolism.

    Implications:

    • One-stage bilateral knee arthroplasty is recommended for patients with severe knee arthritis due to comparable efficacy and reduced thromboembolic risk.
    • This finding supports the adoption of one-stage bilateral procedures, potentially improving patient convenience and reducing overall healthcare burden.
