Computer-assisted surgical navigation systems are increasingly used in orthopaedics, especially for knee replacement. These systems enhance surgical precision by tracking instruments and anatomy in real-time.

Area of Science:

  • Orthopaedic Surgery
  • Medical Technology
  • Surgical Navigation

Context:

  • Computer-assisted surgical navigation is gaining acceptance in orthopaedics.
  • Knee replacement surgery is a key area for navigation system application.

Purpose:

  • To describe the technological concepts of modern computer-assisted surgical systems.
  • To explain the variations in currently available navigation systems.
  • To outline research influencing future surgical navigation products.

Summary:

  • Navigation systems comprise three components: the anatomical structure (therapeutic object), its digital representation (virtual object), and the navigator tracking instruments and anatomy.
  • The navigator provides real-time spatial data for surgical action replay on-screen.

Related Experiment Videos

  • Radiological images or computer-generated models serve as virtual objects.

    • Impact:

    • Improved precision in orthopaedic procedures, particularly knee replacements.
    • Potential for enhanced surgical outcomes through real-time guidance.
    • Advancement of future surgical navigation technologies.
