Meniscus Tear: Definition, Anatomy, Causes, Classifications, Symptoms & Treatment


What is Meniscus?

Meniscus tears are highly prevalent among knee injuries. Each knee joint contains two wedge-shaped pieces of cartilage (menisci, or singularly, meniscus) that function to cushion impacts between the thighbone (femur) and shinbone (tibia). Without menisci, the body’s weight would not be evenly applied to the bones in the leg, increasing the likelihood of knee injury.

Meniscus Anatomy

In each knee joint, there is a lateral meniscus on the outer side and a medial meniscus on the inner side. The material they are composed of is tough and rubbery which helps to keep the knee joint stable while buffering forces.

Causes of Meniscus Tear

Tears in menisci can occur from playing sports, from explosive squatting and twisting movements, from direct contact like tackling, or from degenerative changes as cartilage weakens and becomes thin with age. Traumatic tears tend to occur vertically in the meniscus and are more likely to result in a movable fragment that can catch in the knee. 

Classifications of Meniscal tears

There are several different classification of meniscal tear. Classifications include:

  1. Radial tears
  2. Flap or parrot-beak tears
  3. Peripheral, longitudinal tears
  4. Bucket-handle tears
  5. Horizontal cleavage tears
  6. Complex, degenerative tears

Symptoms of a Meniscus Tear

Symptoms of a meniscus tear include:

  1. Knee pain
  2. Swelling
  3. Joint locking (unable to straighten leg fully)
  4. Sensation of the knee “giving way”
