Meniscus

The meniscus is a cartilaginous surface that sits on top of the tibia, the larger of the two bones that comprise the lower leg, which is responsible for shock absorption and stability throughout the knee joint. The most common cause of meniscal tears is pivoting on a planter foot while the knee is in a flexed or bent position. Symptoms can range from pain with full flexion or extension of the knee to swelling and/or instability.
