ABSTRACT
The objective of this study was to evaluate trochlear morphology in patients with trochlear dysplasia using a new oblique trochlear magnetic resonance imaging (MRI) view (OTV) in comparison with standard axial MRI sequences. MRI exam of 73 patients with patellofemoral instability (PFI) and the same number of controls were retrospectively reviewed. The oblique trochlear sequence was acquired by inclining the axial plane parallel to the intercondylar roof of the sagittal image, showing the anterior cruciate ligament (ACL) in its entire length. Trochlear morphology was assessed on axial and oblique trochlear sequences at three levels level 1 at 25%, level 2 at 50%, and level 3 at 75% of the length of the trochlear groove. Trochlear sulcus angle and sulcus depth were measured at these three levels and compared between the new trochlear and standard axial sequences. Trochlear sulcus angle and sulcus depth were statistically different between axial and oblique trochlear views at all three levels (p < 0,05). Additionally, OTV displayed more uniform sulcus angle and depth along the trochlea. The oblique trochlear view on the MRI can more accurately evaluate trochlear morphology and also better characterize trochlear dysplasia in patients with PFI. This is Level III, retrospective comparative study.
