| Abstract: | Objective: To use an extremity magnetic resonance system to perform kinematic magnetic resonance imaging (MRI) of the patellofemoral joint to qualitatively assess the effect of bracing on patellar position. Design and Setting: Subjects underwent kinematic MRI of the symptomatic extremity with a 0.2-Tesla extremity magnetic resonance system. Images were obtained using a knee coil and a T1-weighted, spin echo pulse sequence. Subjects: Seven female patients with patellofemoral joint symptoms. Measurements: Four different axial sections were obtained for each position: extension and 3 positions of flexion up to 36°. An appropriate-sized patellofemoral brace was applied, and the kinematic MRI procedure was repeated. Results: Six patients had lateral displacement of the patella, and 1 patient had medial displacement of the patella. After application of the brace, 6 patients (5 with lateral displacement and 1 with medial displacement, 86%) exhibited correction (5) or improvement (1 with lateral displacement) in the abnormal patellar positions, and 1 patient had worsening of the abnormal position of the patella. Conclusions: We used kinematic MRI to determine the presence of abnormal patellar positioning. Application of the brace counteracted the abnormal patellar positions in most of the patients studied.
