(A) Thickness of superficial zone and deeper zones disks of the medial, lateral condyle and the patella-femoral groove. (B) Equilibrium modulus of superficial zone and deeper zones disks. (C) Dynamic stiffness of superficial zone and deeper zones disks.
(A, B, C) Each group of superficial zone disks: n ≥ 7; each group of deeper zones disks: n ≥ 12. MC = medial condyle, LC = lateral condyle, G = patellofemoral groove.
