WebCase Discussion. Patella height, trochlear depth, and trochlear morphology are some of the measurements obtained when reporting cases of patellofemoral instability on MRI. The stacks of images can be used to conveniently review the different measurement techniques. WebTrochlear Depth. This measures the inset depth of the trochlear groove (sulcus) relative to the average of the maximum anteroposterior distance of the medial and lateral femoral condyles (it is determined on axial images at the same level as trochlear facet asymmetry). A trochlear depth of less than 3mm is considered abnormal.
