Definition: A meniscus is a type of cartilage found in some joints in the body. The best known meniscus is within the knee joint. There is also a meniscus in the shoulder, wrist, and elbow, but most people are concerned about the knee meniscus.
The knee joint is made up of three bones, the femur, tibia, and patella. The surfaces of these bones at the knee joint are covered with a type of cartilage called articular cartilage. This surface allows the bones to slide against each other without causing damage to the bone. The meniscus is a different type of cartilage that sits between the articular surfaces to distribute weight and to improve the stability of the joint.
