    This study evaluated hand-operated instruments for arthroscopic knee surgery, finding mechanical issues in some cases. Improved instrument design and selection criteria are crucial for patient safety and surgical success.

    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering
    • Surgical Instrumentation

    Background:

    • Arthroscopic knee surgery relies heavily on specialized hand-operated instruments.
    • Instrument performance and potential complications are critical factors in surgical outcomes.

    Purpose of the Study:

    • To evaluate the performance and safety of a 10-part hand-operated instrument set used in arthroscopic knee surgery.
    • To identify instrument-dependent complications and areas for improvement in arthroscopic surgical tools.

    Main Methods:

    • Analysis of 500 arthroscopic operations, noting procedure types and complications.
    • Laboratory simulations and biomechanical testing (traction and bending experiments) of instruments and meniscus tissue.

    Main Results:

    Related Experiment Videos

    • Instrument-dependent complications occurred in 4 cases.
    • Simulations revealed undesired instrument movements based on construction.
    • Arthroscopic forceps showed inferior grasping compared to conventional clamps.
    • Some instrument materials were prone to breakage after minimal bending cycles.

    Conclusions:

    • Hand-operated instruments for arthroscopic knee surgery require careful selection and use.
    • Instrument design limitations can impact surgical effectiveness and patient safety.
    • Further research into instrument biomechanics and material properties is warranted.
