Meniscal Extrusion in the Knee 19 were 102 cases with extrusion of 3 mm or more (50.5%) on coronal MRI. Extrusion of the meniscus can also be frequently accompanied by OA.79 Meniscus extrusion is one of the substantial risk factors of OA progression,29 and it strongly correlates with patient symptoms.79 Therefore, a surgical procedure that can reduce the displacement of meniscus could lead to preserving the meniscal function, thereby preventing the progression to OA. The radiologist interprets at the images and provides a report to your doctor.
