Knee injuries

Knees provide stable support for the body and allow the legs to bend and straighten.

The knee is the largest joint in the body and is easily injured. The knee has 4 main types of tissues: bones, ligaments, cartilage, and tendons. Any of these important types of tissue can be damaged through injury.

Common knee injuries include:

  • sprains (an over-stretching of ligaments in the knee)
  • strains (over-stretching of muscles and tendons)
  • damage to the cartilage that lines the knee
  • irritation to the kneecap joint.

Less common injuries to the knee include:

  • fractures (usually caused by sudden trauma or a direct blow, twisting, or falling on the knee)
  • kneecap dislocations
  • knee joint dislocations (uncommon as it requires a great force).

Knee damage can also occur from underlying disease such as osteoarthritis, rheumatoid arthritis and systemic lupus erythematosus.
