From: Varus stress MRI in diagnosis of medial meniscal posterior root tear
A 46-year-old female homemaker patient, obese (BMI = 41.4 kg/m2), presented with significant posteromedial left knee pain with a popping sound for 7 weeks (subacute stage) after stepping into a hole. By the comparison between the pre- and post-varus stress medial meniscus extrusion amount (MME). Without varus stress position (a and c), the coronal PD-SPAIR WI of the left knee shows an extruded medial meniscus of approximately 3.4 mm from the medial margin of the tibial plateau to the outer border of the extruded meniscus (orange arrow). With varus stress position (b and d), shows an increased MME amount of approximately 6.8 mm (red arrow)
