damaged cartillage

There are several options available for treatment of damaged cartilage. I am sure your doctor will determine which option is right for you. That determination should be based on the type and extent of your injury.
It is important to note that early intervention may help to prevent damage from spreading to surrounding healthy cartilage. That should prevent further deterioration to the joint surface.
Damaged cartilage, which is caused by traumatic injury or the regular wear and tear of age, is almost impossible to repair on its own. Cartilage differs from other parts of tissues and lacks the blood vessels that deliver nutrients and other healing substances to damaged regions. Medical treatment usually aims only to alleviation of pain, but unfortunately without resources to replenish damaged cartilage.
