Meniscus Conditions

A discoid meniscus is thicker than normal and oval-shaped (rather than C-shaped). It may lack the normal peripheral attachments that give the meniscus stability.

The meniscus acts like a shock absorber in the knee joint. It is a C-shaped structure that lies between the femur and tibia. Each knee has 2 menisci, one on the inside (medial) and one on the outside (lateral). A meniscus tear can occur with a traumatic knee injury and can cause pain and swelling within the knee.
