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. They can be damaged or torn during activities that put pressure on or rotate the knee joint.
Meniscus tears are common in contact sports like football as well as noncontact sports requiring jumping and cutting such as volleyball and soccer. They can happen when a person changes direction suddenly while running.
Meniscus tears are a special risk for older athletes since the meniscus weakens with age. More than 40% of people 65 or older have them.
To learn more you should go to a specialist.
