Trochlear dysplasia is defined as abnormal shape of the trochlea. It can be shallow, flat, or convex (Fig. 35.1.This anatomic status fails to provide adequate constraint to the normal patellar tracking. Trochlear dysplasia is found in 96% of the populationwith objective patellar dislocation (at least one true dislocation).8 This clearly demonstrates its importance in the genesis of the instability.
