The meniscus is a piece of cartilage that provides a cushion between your femur (thighbone) and tibia (shinbone). There are two menisci in each knee joint.
Damage to a meniscus, the cartilage that cushions the knee, often occurs with twisting the knee. Large tears may cause the knee to lock. a meniscal tear is one of the most frequently occurring cartilage injuries of the knee.
- The meniscus can be torn during activities that cause direct contact or pressure from a forced twist or rotation. A sudden pivot or turn, deep squatting, or heavy lifting can lead to injury. Many athletes are at risk for a meniscus tear.
- Sports that require sudden turns and stops may put you at higher risk for meniscus tears.
