High Level MRI Scan Usage for the Detection of Meniscus Posterior Root Pathology.

What is it about?

This article reviewed a consecutive series of patients who had meniscus root tears and compared the diagnostic accuracy to a 3-Tesla MRI scan. These MRIs are considered the highest strength MRIs currently approved by the FDA.

Why is it important?

This article is important because it found that many meniscus root tears are missed on high strength MRI scans. Once should look at multiple cuts on the MRI scan to look at disruption of the meniscal attachment, the ghost sign, and extrusion of the meniscus as signs of a meniscus root tear.

This article demonstrates that orthopaedic surgeons should always read their own MRIs when assessing for meniscal root tears. This is because of commonly missed, even on a high strength MRI scan, when they are read by a musculoskeletal radiologist. All of the secondary signs of a meniscus root tear should be looked at to ensure that one can effectively diagnose a meniscus root tear and treat them appropriately by a meniscus root repair.
