Posterior tibial slope exists when the top of the tibia slopes downward towards the back of the knee. A few degrees of posterior slope is normal.

Measurement of posterior tibial slope

To measure the angle of tibial slope, a line is drawn on an X-ray along the front of the tibia (anterior tibial cortex line) (A). Then a line is drawn perpendicular to the anterior tibial cortex line (B). Finally a line is drawn along the top of the tibial plateau (C), and the angle of the posterior tibial slope is the angle formed by B and C.
