Introduction:
Within a 15-month period, 64 patients underwent 71 primary total knee arthroplasties in a randomized trial comparing the navigated versus the conventional implantation technique. CT scans were chosen for use as imaging procedures pre- and post-operatively to collect data concerning alignment and rotation of the leg as well as the prosthesis.
Results:
There was no difference between pre- and post-operative data in rotation of the femoral component for navigated versus conventional implantation. The average deviation from the correct long-leg axis was found to be 1.8 +/- 1.3 degrees in the navigated group and 2.5 +/- 1.6 degrees in the conventional group (P < 0.05).
