[Anatomy_08] Medial Meniscus Anterior Root

https://youtu.be/es0xkT3-Wmo

 

The medial meniscus becomes flattened as it transitions into the anterior root medial meniscus (ARMM)

This is made up of a single fiber bundle and is the largest of the four roots.

The anterior root lateral meniscus (ARLM) and posterior root medial meniscus (PRMM) are made up of multiple fibre bundles(consists of three or more bundles.

 

In 15% of individuals, the ARMM attaches onto the anterior margin of the tibia near the midline (Fig. 2c) [10], resulting in anterior subluxation of the meniscus at the mid-portion of the medial tibial plateau.

​​However, this is a normal variant which is of no clinical significance 

This subluxation is a normal variation, giving the false impression of extrusion or pathologic subluxation

It's not a real patient's MRI, but they are virtual images very similar to the images in the journals. The images will be created for educational purposes.
