ACL (Anterior Cruciate Ligament) Tear

kneeFour main ligaments hold the knee joints together:

  • The medial collateral ligament
  • Lateral collateral ligament
  • Anterior cruciate ligament (ACL)
  • Posterior cruciate ligament  

The cruciate ligaments cannot heal once they are torn.

ACL tears occur two to six times more often in females than in males involved in the same amount of sports activities.

However, due to the higher level of male participation in contact and collision sports, the overall number of cruciate ligament injuries remains higher in males.

ACL injuries can be linked with injuries to the cartilage in the knee, which can complicate matters.
