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.
Meniscal cartilage is the smooth, tough, rubbery, half-moon-shaped tissue that lines your knee joint. It helps the knee bones glide easily over each other, absorbs shock and acts to stabilize the joint. The knee joint contains an inner (or medial) meniscus and an outer (or lateral) meniscus (Figure 1). 1  The medial meniscus is torn much more often than the lateral meniscus.  There are many shapes and sizes of meniscal tears and some cause more problems than others.
