Meniscus tear

Definition

Prevalent in patients with degenerative arthritis in their late 50s and in athletes

Menisci locate between the upper bone (femur) and lower bone (tibia) of the knees, distributes the body weight and external impacts, and lubricates the joint. Menisci can become torn by degenerative changes or trauma, induce pain, and advance into degenerative arthritis. Athletes carry such risk in their exercise routine. Those who are in their late 50s may experience a sudden tear after developing advanced degenerative arthritis.

Congenital deformity or degenerative change

  • Approximately 5-10% of population has a congenital deformity of lateral meniscus
  • Degenerative changes aggravated by postures that burden the knees(squatting)
