    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering
    • Robotics

    Background:

    • Effective total knee arthroplasty (TKA) relies on precise soft tissue balance.
    • Imbalances can lead to knee laxity or necessitate revision surgery.

    Purpose of the Study:

    • To introduce a novel robotic tensor system for measuring soft tissue balance during TKA.
    • To assess collateral ligament balance, including joint gap and varus angle.

    Main Methods:

    • Development of a robotic tensor system with active prismatic and passive rotation joints.
    • System designed to apply controlled lifting force to the knee joint.
    • Measurement of joint gap (30 mm range) and varus angle (±15°).

    Main Results:

    • The prototype system demonstrated accurate force control, with errors within 3N for applied forces up to 250 N.
    • The system effectively measures joint gap and varus angle.
    • Achieved accuracy surpasses previous instrumental methods.

    Conclusions:

    • The newly developed robotic tensor system shows promise for enhancing TKA outcomes.
    • Accurate soft tissue balance measurement can improve surgical precision.
    • This technology may reduce the incidence of TKA complications like laxity and revision.
