The meniscus is a c-shaped piece of cartilage in your knee joint. You have two in each knee.
The meniscus forms a tough but flexible cushion between the bones in your knee to protect the joint. The meniscus:
- Acts like a shock-absorber
- Helps distribute the weight to the cartilage
- Helps to stabilize your knee joint
- Can tear and limit your ability to flex and extend your knee
