Meniscus tears

Alternative names:

injury - knee - meniscus; knee injury - meniscus; tear - meniscus

Definition:

A tear of the meniscus that can result in a leakage of fluid within the knee (synovial fluid) into surrounding tissue.

Causes, incidence, and risk factors:

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

Meniscal tears are most commonly caused by twisting or hyperflexion of the joint.
