Annotated images showing the different measurements in this case:
lateral trochlear inclination (LTI) = 10.8° (an angle <11° indicates trochlear dysplasia)
trochlear depth (TD) = 2.2 mm (a trochlear depth <3 mm indicates trochlear dysplasia)
facet asymmetry (FA) = 33 % (a ratio of <40%, in this case, indicates trochlear dysplasia)
