How is a torn meniscus identified on MRI?
They are diagnosed on MRI by the presence of a vertical line of increased signal intensity contacting the superior, inferior, or both surfaces of the meniscus (Fig. 16).
Does a medial meniscus tear always need surgery?
How is a meniscus tear treated? If your MRI indicates a Grade 1 or 2 tear, but your symptoms and physical exam are inconsistent with a tear, surgery may not be needed.

How often are meniscus tears missed on MRI?
The sensitivity and specificity of MRI in determining medial and lateral meniscus tears were 91.8% and 79.9%, and 80.8% and 85.4%, respectively. The accuracy of MRI in the ACL-injured group was lower than that in the ACL-intact group (medial meniscus: 81.7% vs. 88.1%, p = 0.041; 72.9% vs.
What does white mean in knee MRI?

This is due to a high riding Patella. The patella will first engage into the trochlea area when the knee is flexed several degrees.
