MRI of the same patient: comparison between the pre- and post-varus stress medial meniscus extrusion amount (MME) (c). Without varus stress position (left upper and left lower), the coronal PD-SPAIR WI of the left knee shows an extruded medial meniscus of approximately 5 mm (from the end of the medial tibial plateau to the end of the extruded meniscus) (orange arrow). With varus stress position (right upper and right lower), MME increased up to 10 mm from the end of the medial tibial plateau to the end of the extruded meniscus (red arrow)
