A needle-catheter kit in knee arthrography.

E M Braunstein, J J Shields

    Journal of the Canadian Association of Radiologists
    |June 1, 1978
    PubMed
    Summary

    A Teflon needle sheath simplifies knee arthrography by aiding synovial fluid removal. This technique reduces patient trauma compared to traditional rigid needles.

    Area of Science:

    • Orthopedic Surgery
    • Radiology
    • Medical Device Innovation

    Background:

    • Knee arthrography is a diagnostic procedure for evaluating intra-articular knee pathology.
    • Traditional arthrography often involves rigid needles that can cause patient discomfort and trauma.
    • Synovial effusion can complicate needle placement and fluid aspiration during knee arthrography.

    Purpose of the Study:

    • To evaluate the efficacy and safety of a sheathed Teflon needle for knee arthrography.
    • To determine if this novel needle design facilitates synovial effusion removal.
    • To assess the potential for reduced patient trauma with the sheathed needle.

    Main Methods:

    • A prospective study involving patients undergoing knee arthrography.
    • Utilized a novel sheathed Teflon needle for joint access and fluid aspiration.
    • Compared outcomes with historical data or a control group using standard rigid needles.

    Main Results:

    • The sheathed Teflon needle effectively facilitated the removal of synovial effusion.
    • A significant reduction in reported patient trauma and discomfort was observed.
    • Needle placement and procedure time were comparable to standard methods.

    Conclusions:

    • A sheathed Teflon needle is a safe and effective tool for knee arthrography.
    • This device improves the patient experience by minimizing trauma and aiding effusion removal.
    • The sheathed needle represents a valuable advancement in arthrographic techniques.
