A grade II signal in the meniscus on MRI
indicates an internal abnormality in the
meniscus, but no definite evidence of
a frank tear is seen on the images. Therefore, the definitive diagnosis must be made on the basis of all the clinical information and the MRI combined. The further information your doctor will use are the history: did you fall or twist your knee, or did it just started hurting after you got off the stepper? was, or is, your knee swollen? what makes it hurt?
