What is a knee meniscus?
There are 2 menisci (plural of meniscus) in each knee. They are made of cartilage (like the soft tip of your nose) and act as shock absorbers in the knee. Each is a C-shaped washer between the femur (thigh bone) and the tibia (shin bone). The meniscus on the inner (medial) side of the knee is called the medial meniscus and the one on the outer (lateral) side of the knee is the lateral meniscus.
