The meniscus is a c-shaped piece of cartilage in your knee joint. You have two in each knee.
- Meniscus cartilage is a tough but flexible tissue that acts as a cushion between the ends of bones in a joint.
- Meniscus tears refer to tears in this shock-absorbing cartilage of the knee.
More About Your Injury
The meniscus forms a buffer between the bones in your knee to protect the joint. The meniscus:
- Acts like a shock-absorber
- Helps lubricate your knee joint
- Can tear and limit your ability to flex and extend your knee
A meniscus tear can occur if you:
- Twist or over-flex your knee
- Quickly stop moving and change direction while running, landing from a jump, or turning
- Kneel down
- Squat down low and lift something heavy
- Get hit on your knee, such as during a football tackle
As you get older, your meniscus ages too, and it can become easier to injure.
