Meniscus Tear

Summary & Treatment

What is the Meniscus?

  • The menisci are two pads of cartilaginous tissue which serve to disperse friction in the knee joint between the lower leg (tibia) and the thigh (femur).
  • The knee contains a lateral meniscus and a medial meniscus.
  • Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion.

Arthroscopic Partial Menisectomy

What Does It Do?

  • Shock Absorption
    • The menisci act to disperse the weight of the body and reduce friction during movement.
    • Since the ends of the thigh bone and shin bone meet at one point (which changes during flexion and extension), the menisci spread the load of the body’s weight.
    • This protects the integrity of the articular cartilage of the knee joint.

Meniscus Tears

  • Torn or worn away from overuse, age, or injury.
  • Common in sports such as soccer & basketball.
  • Commonly related to anterior cruciate ligament injuries of the knee.
  • The knee will be in pain when in use.
  • But when there is no load, the pain goes away.
  • Some meniscal tears can cause jamming or locking of the knee.

Different Types of Meniscus Tears

Treatment

  • Observation / physiotherapy
  • Arthroscopic menisectomy
    • Partial or total
  • Arthroscopic meniscus repair

Observation

  • Suitable for partial thickness tears
  • Small tears close to capsule
    • possible to heal on its own
