Abstract:

Objective   To explore the effect of the tibialis anterior tendon in the total knee arthroplasty of the extramedullary alignment.   Methods    The ankle center and the tibial coronal alignment in 59 lower limbs of the 59 osteoarthritis were confirmed with X-ray and was marked in the skin, the medial border of tibialis anterior tendon was also marked in the skin. The distance of the tibialis anterior tendon to the ankle center was measured at the ankle line, the distance of junction of tibialis anterior tendon and tibial coronal alignment to the ankle line also was measured. The independent t test was performed for both distances.   Results    The distance of the tibialis anterior tendon to the ankle center was (13.32±2.75) mm (P<0.001), and the distance of the junction of the tibialis anterior tendon and the tibial alignment to the ankle line was (71.23±6.45) mm (P<0.001).   Conclusion    The tibialis anterior tendon has 2 points that could serve as the distal tibial anatomical landmark in extramedullary alignment of total knee arthroplasty, it could be applied in the total knee arthroplasty clinically.
