Background: There is no general consensus on the normal and pathological values for the posterior tibial slope (PTS). Purpose/Hypothesis: The primary aim of this study was to determine standard values for the PTS in healthy participants using 3dimensional (3D) computed tomography (CT). A secondary aim was to determine the effect of demographic factors and coronalplane lower limb alignment on the PTS measurement. The hypothesis was that the PTS would be significantly influenced by demographic factors and coronal-plane lower limb alignment.
