Symptoms of a posterior horn medial meniscus tear:
Symptoms of a meniscus tear include:
There are 3 criteria for the diagnosis of a meniscal cyst:
Medial meniscal root tears are “radial” tears within 1 cm of the meniscal root insertion or an avulsion of the insertion of the meniscus. These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses.
The posterior horn of the medial meniscus attaches to bone close to the center of the knee and just above the PCL. This attachment site is called the root. Tears of the root can cause the meniscus to slip out of the joint, also called extrusion, which can significantly overload the cartilage.

The meniscus root is where the main body of the meniscus attaches to the bone. There are meniscal root attachments both in the front and back of the tibia.
Medial meniscus posterior root tears are commonly degenerative and seen in middle aged women and may represent up to 21.5% of posterior horn medial meniscus tears (11). Iatrogenic MPRT have also been reported after non-anatomic tibial tunnel placement in posterior cruciate ligament (PCL) reconstructions (12).
In a meniscus root tear, the meniscus is damaged near its attachment to the bone. In a 'repair' procedure, stitches are used to reattach the torn meniscus back to the bone. This is done by drilling a small tunnel in the bone from just below the knee, exiting where the meniscus tore away from the bone.

A meniscal root tear is defined as an avulsion of the attachment, or a complete radial tear within 1 cm of the anterior or posterior tibial attachments of the menisci.

Medial meniscus extrusion (MME) is defined as medial displacement of the body of the meniscus beyond the outermost margin of the medial tibial plateau and is measured in the mid-coronal plane through the knee joint. The mid-coronal plane is defined as the slice with the largest area of the medial spine.
