This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water â hence the name photosynthesis, from the Greek Ïá¿¶Ï, phÅs, light, and ÏÏÎ½Î¸ÎµÏÎ¹Ï, synthesis, putting together.
The human body's own cartilage is still the best material for lining knee joints. This drives efforts to develop ways of using a person's own cells to grow, or re-grow cartilage tissue to replace missing or damaged cartilage.
The chondrocytes from the cartilage are then isolated and grown in the laboratory over a 6-8 week period. After a sufficient number of chondrocytes has been cultured, they are injected back into the defect of the knee, where a periosteal flap covers the defect.
