Meniscus tears

• Overview
• Symptoms
• Treatment
• Prevention

Definition:

Meniscus tears describes a tear in the shock-absorbing cartilage (meniscus) of the knee.

Alternative Names:

Tear - meniscus; Knee injury - meniscus; Cartilage tear

Considerations:

The meniscus is a C-shaped fibrous piece of cartilage which is found in certain joints and forms a buffer between the bones to protect the joint. The meniscus also serves as a shock-absorption system, assists in lubricating the joint, and limits the joint flexion and extension.

Causes:

Meniscal tears are most commonly caused by twisting or over-flexing the joint.
