The human body has an inherent ability to heal tissue, but in certain areas that capacity is inadequate. New cells are created all the time in the body, in order to replace old or damaged tissue, but, with age, this capability decreases. Even in younger individuals, sometimes knee cartilage is slow to regenerate. Certain conditions, such as degenerative arthritis, can cause severe joint pain, and conventional medicine offers treatment that may mask the pain temporarily, but not alter the condition itself. With the help of regenerative medicine and options such as platelet rich plasma therapy (PRP), things are changing right now to repair damaged tissue.
