Electromagnetic (EM) navigation in total knee arthroplasty accurately restores leg alignment, achieving ideal mechanical axis in 30 of 32 cases. This system demonstrates safety and effectiveness for precise implant positioning.

Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Accurate implant positioning and leg alignment are crucial for long-term success in total knee arthroplasty (TKA).
  • Computer navigation systems, including optical and electromagnetic (EM) tracking, aim to improve component placement and restore the mechanical axis.
  • EM navigation offers advantages like no line-of-sight issues but requires specialized instruments.

Purpose of the Study:

  • To analyze the postoperative radiological results of total knee arthroplasty using an Electromagnetic (EM) navigation system.
  • To evaluate the accuracy of implant positioning and leg alignment reconstruction with EM navigation.

Main Methods:

  • Retrospective analysis of 32 knees treated with EM navigation system for total knee arthroplasty.

Published on: May 6, 2016

  • Postoperative radiological measurements of component angles and mechanical axis were performed by five independent physicians using specialized software.
  • Each radiograph was measured three times at delayed intervals to ensure reliability.

    • Main Results:

    • Ideal mechanical axis alignment (180°±3°) was achieved in 30 out of 32 cases.
    • Femoral and tibial frontal component angles were within ±3° of the desired 90° in all patients.
    • EM navigation showed high correlation with radiological assessment, with no system-related complications reported.

    Conclusions:

    • Electromagnetic navigation is a safe and effective tool for achieving accurate implant positioning and leg alignment in total knee arthroplasty.
    • The system facilitates precise reconstruction of the mechanical axis, leading to excellent radiological outcomes.
    • EM navigation provides reliable results comparable to independent radiological review.
