Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total knee arthroplasty (TKA) success relies on precise component positioning and limb alignment.
  • Malalignment exceeding 3 degrees significantly increases TKA failure rates and reduces longevity.
  • Computer-assisted navigation (CAN) systems aim to enhance implant accuracy.

Purpose of the Study:

  • To evaluate the early outcomes of TKA using an image-free CAN system.
  • To compare component positioning and limb alignment accuracy between CAN and conventional TKA methods.
  • To assess the impact of CAN on reducing alignment outliers.

Main Methods:

  • A prospective study comparing a navigation group (116 patients) with a conventional group (51 patients).
  • Utilized an image-free computer-assisted navigation system for implant placement in the navigation group.

  • Postoperative mechanical axis and component alignment were measured and compared between groups.

    • Main Results:

    • 95% of navigation cases achieved neutral mechanical alignment (within 3 degrees) versus 84% in the conventional group (P < .02).
    • The navigation group demonstrated a narrower range of alignment and component position measurements.
    • Undesired outliers in alignment and component positioning were significantly reduced with CAN.

    Conclusions:

    • Image-free computer-assisted navigation is a viable tool for improving TKA outcomes.
    • CAN enhances accuracy in component positioning and limb alignment compared to conventional techniques.
    • Improved alignment accuracy with CAN is associated with better early TKA results.
