A: Though it is made of cells and tissues, cartilage cannot repair itself due to the lack of blood vessels and enough blood supply to create and duplicate new cells .
How long does cartilage in knee take to heal?
After cartilage injury there must be a six-week period of non-weight bearing, but full recovery can take up to a year to fully heal and regain the full range of movement.
What vitamins help repair cartilage?
Glucosamine, chondroitin, omega-3, and green tea are just a few of them. Glucosamine helps keep the cartilage in joints healthy and may have an anti-inflammatory effect. Natural glucosamine levels drop as people age. Chondroitin is often used with glucosamine as an osteoarthritis treatment.
