M23.09: Cystic meniscus: Unspecified meniscus
One or more fluid-filled cavities have formed in your knee.
In the knee joint, the thighbone (femur) is connected to the shinbone (tibia). Between the two bones are two pieces of crescent-shaped cartilage. These pieces of cartilage and fiber are the menisci. There is a medial meniscus and a lateral meniscus. The medial meniscus is on the inside of the leg, while the lateral meniscus is on the outside of the leg. The menisci perform various functions. They balance out any unevenness in the joint surfaces of the bones. The menisci also act as shock absorbers. They absorb violent shocks.
When the knee comes under pressure, the menisci in the knee can tear. This can cause a fluid-filled cavity to form in or around the meniscus. Such a cavity and fluid can cause swelling on the outside or inside of the knee. This swelling may be painful.
