The clinical diagnosis of femoral trochlear dysplasia primarily relies on imaging. In the past, plain imaging was major source diagnosis. present study investigated application magnetic resonance (MRI) in objective assessment severe dysplasia. A retrospective analysis performed knee MRIs from 30 normal subjects (30 knees) and 59 patients (61 with based Dejour morphological classification. Cartilage subchondral bone landmarks were used to compare a series measurements between patient control groups. These included groove depth, sulcus angle, lateral inclination, facet asymmetry, medial condyle symmetry, ratios medial/lateral condyles maximal width. measurement values two types also compared within groups, separately. addition, inclination asymmetry different compared. Significant differences observed groups (P<0.05). Based landmark, all indexes significantly (P<0.05; exception inclination) Among various types, demonstrated no significant differences. MRI exhibited advantages revealing articular cartilage over conventional radiography computed tomography. Therefore, images may be utilized objectively evaluate
