MRI is the criterion standard imaging study for imaging meniscus pathology and all intra-articular disorders.

Normal menisci have a homogeneous low signal. Abnormal meniscal signals are classified into the following three groups:

  • Grade I – Small area of increased signal within the meniscus

  • Grade II – Linear area of increased signal that does not extend to an articulating surface

  • Grade III – Abnormal increased signal that reaches the surface or edge of the meniscus
