The meniscus (plural: meniscuses, from the Greek for "crescent") is the curve in the upper surface of a standing body of liquid, produced in response to the surface of the container or another object. It can be either convex or concave.
The menisci or articular discs are structures that separate a joint cavity in to two compartments. They are found in the knee, jaw and sternoclavicular joints. It only partly divides a joint cavity and it can be torn in an action that puts pressure on the joint while the joint is turning.
Symptoms of a damaged/torn meniscus could be knee pain, swelling of the knee, tenderness when touching the meniscus, popping or clicking with the knee, and limited motion of the knee joint.
