Themeniscusis a C-shaped wedge of cartilage that helps support and cushion the knee joint.
In some people, the lateral meniscus is shaped more like a solid disc rather than the normal C-shape.
Most people with a discoid meniscus never know they have an abnormality.

Most people live normal, active lives with a discoid meniscuseven high performance athletes.
Again, in both of these scenarios, the discoid lateral meniscus is best left alone.
This is why some people use the phrase ‘popping knee syndrome’ when talking about a discoid meniscus.
The normal meniscus contours are absent, and more meniscus tissue than normal is seen on the MRI.
If there is a tear in the discoid meniscus, that is typically seen on the MRI as well.
If the discoid meniscus is torn, there are several approaches to managing this arthroscopically.
Historically, the entire meniscus was removed at the time of arthroscopic surgery.
This surgical procedure is called a complete meniscectomy.
In the end, some of the meniscus may be removed and some may be repaired.
Most patients require no immobilization and limited restrictions of weight-bearing.
Any patient who sustains a meniscus tear should take steps to helpprevent any progression of arthritisin their knee joints.
