Posterior tibial slope (PTS) is the slope of the tibial plateau from anterior to posterior relative to the longitudinal axis of the tibia.
Posterior tibial slope can affect knee range of motion, flexion gap, knee joint stability, ACL ligament stability and posterior femoral rollback 1,2. Measurement and usage of this angle has important role in total knee replacement, high tibial osteotomy, and anterior cruciate ligament reconstruction 3.
It is measured by drawing two lines both tangential of posterior tibial cortex and tibial plateau. The angle between the two lines is the posterior tibial slope 1.
Mean posterior tibial slope angle was around 7.7 degrees in medial compartment to that of 6.85 in lateral 1.
Increased (up to 5x) risk of further injury after ACL reconstruction with a posterior tibial slope of ≥12° 3.
