Evaluation of Medial Meniscal Extrusion Using Radiography

Recently, there has been increasing interest in medial meniscal extrusion (MME), but few reports have evaluated MME via X-ray. In this study, the amount of and height at border tibia were measured X-ray with gradation processing. The length divided by yields ratio, which was used as an index. addition, part protruding from on MRI absolute value. Then, correlation between ratio examined, a strong (correlation coefficient 0.860, p < 0.0001). cut-off value for positive 0.50, AUC 0.9825, sensitivity 0.9063, specificity 0.8663. From present it possible to measure processing, without MRI, calculate strongly correlates MRI.
