Image-free navigation systems are increasingly accepted for knee surgery, significantly reducing mechanical axis deviations in knee arthroplasty. Future developments aim for image-free navigation in high tibial osteotomies.

Area of Science:

  • Orthopedic Surgery
  • Medical Technology
  • Surgical Navigation

Background:

  • Surgical navigation systems for knee joint operations have gained prominence in the last five years.
  • Image-free kinematic systems are widely adopted, with C-arm based systems showing no superiority.
  • CT-based systems offer advantages for severely damaged or deformed joints.

Purpose of the Study:

  • To review the current status and applications of navigation systems in knee joint surgery.
  • To evaluate the efficacy of different navigation techniques, including image-free and image-based systems.
  • To discuss future trends and potential applications of navigation in orthopedic procedures.

Main Methods:

  • Review of established and emerging navigation technologies in knee surgery.

Related Experiment Videos

  • Comparison of image-free kinematic systems, C-arm based systems, and CT-based systems.
  • Analysis of the application of navigation in knee arthroplasty and high tibial osteotomies.

    • Main Results:

    • Image-free navigation is highly effective in resurfacing knee arthroplasty, minimizing mechanical axis errors.
    • CT-based systems are beneficial for complex joint reconstructions.
    • Intraoperative imaging is currently essential for high tibial osteotomies but is expected to become image-free.

    Conclusions:

    • Image-free navigation is a reliable tool for knee arthroplasty, improving accuracy.
    • Further development is needed for cruciate ligament navigation due to time constraints.
    • Navigation technology is advancing, with image-free solutions becoming standard for various knee procedures.
