Coronal MR image, acquired with an SPGR sequence with water excitation. The image shows the tibiofemoral cartilage plates: MT= medial tibia, LT= lateral tibia, cMF= medial weight-bearing femur; cLT= lateral weight-bearing femur, and the subchondral bone area that was segmented in these areas
a) Neutrally aligned knee: MT = medial tibia, cMF = central (weight-bearing) medial femur, LT = lateral tibia, cLF = central (weight-bearing) lateral femur
b) Knee with varus malignment: lines and brackets indicate the subchondral bone contour over which the subchondral bone area is measured in the medial femorotibial compartment
c) Knee with valgus malignment: lines and brackets indicate the subchondral bone contour over which the subchondral bone area is measured in the lateral femorotibial compartment
