What are Meniscal Tears?
A meniscal tear is a tear that occurs in the cartilage of the knee. The meniscus is a small, "C" shaped piece of cartilage in the knee joint. Each knee has two menisci, the medial meniscus on the inner aspect of the knee and the lateral meniscus on the outer aspect of the knee. The medial and lateral menisci provide a cushion between the thigh bone (femur) and shin bone (tibia) and act as shock absorbers to stabilize the knee joint.
Meniscal tears are one of the most common injuries to the knee joint. They can occur at any age, but are more common in athletes playing contact sports. A sudden bend or twist in your knee can cause the meniscus to tear. Elderly people are more prone to degenerative meniscal tears as the cartilage wears out and weakens with age. A torn meniscus causes pain, swelling, stiffness, or catching or locking sensation in your knee, making you unable to move your knee through its complete range of motion.
