Normal trochlear groove depth
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.
