Comparative study of magnetic resonance imaging (MRI) parameters in a Southeast Asian population with symptomatic patellofemoral instability

BackgroundMRI is performed for evaluation of soft tissue injuries associated with patellar instability.MethodsRetrospective review of MRI parameters from a study group of 64 patients with symptomatic patellofemoral instability and a control group of 64 patients with acute knee injury without concomitant patellofemoral instability was performed.ResultsThe study group demonstrated statistically significant increase (P < 0.05) in all the MRI measurements compared to the control group. There were good inter-observer correlations between surgeon and radiologist for all radiological measurements.ConclusionsIt is prudent to exercise caution in interpreting radiological parameters in different ethnic groups bearing as current treatment protocols are not ethnic-group specific.
