A torn meniscus is an injury to one or more of the two C-shaped pieces of cartilage in each of your knee joints. Any activity that causes you to forcefully twist or rotate your knee, especially when putting the pressure of your full weight on it, can lead to a torn meniscus. In older adults, degenerative changes of the knee may contribute to a torn meniscus.

Conservative treatment, such as rest, ice and medication, is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair.

Symptoms

1)A popping sensation
2)Swelling or stiffness
3)Pain, especially when twisting or rotating your knee
4)Difficulty straightening your knee fully or experiencing what feels like a block to movement of your knee, as if your knee were locked in place.

Causes

Your knee is a complicated joint consisting of various structures, including bones, tendons, cartilage and ligaments. Two C-shaped pieces of cartilage known as the menisci (plural of meniscus) curve around the inside and outside of the knee to stabilize and cushion the joint.

A torn meniscus can result from any activity that causes you to forcefully twist or rotate your knee, such as aggressive pivoting or sudden stops and turns. Even kneeling, deep squatting or lifting something heavy can sometimes lead to a torn meniscus. In older adults, degenerative changes of the knee may contribute to a torn meniscus.

In athletes, a torn meniscus may accompany other injuries, such as a torn anterior cruciate ligament — one of two ligaments that cross in the middle of your knee
