Fig. 2

Measurement meniscus dimensions in 2D-RX, 2D-MRI and 3D-MRI. a2D-RX: Meniscus length = Distance between the anterior surface of the tibia above the tuberosity to the posterior margin of the tibial plateau, perpendicular to the joint line. Multiplication by 0.8 for medial and 0.7 for lateral meniscus. Meniscus width = Distance from the margin of the tibial metaphysis to the medial, respectively lateral tibial eminences, perpendicular to the joint line.b3D-MRI: A best fitting three-dimensional box was placed around the meniscus. X-axis was parallel to a line between anterior and posterior meniscus root. X-axis = meniscus length, Y-axis = meniscus width, Z-axis = meniscus height
