Knee images were analyzed by the same person, blinded
to the experimental set-up of the animal. Images
were opened with ImageJ version 1.45 s (National Institutes
of Health, Bethesda, Maryland) and calibrated. The
two arms of the femorotibial angle were drawn using the
angle tool. The femoral line was drawn from the lateral
condyle to the middle of the femur clamp (aligned with
the femoral diaphysis) (Figure 2). The tibial line went
from the lateral femoral condyle to the lateral malleolus
(Figure 2). The femoro-tibial angle corresponded to the
