PRP is produced from a small sample of a person’s own blood. The blood is centrifuged (spun down) to isolate and concentrate platelets and growth factors, which are the blood cells that assist in natural tissue healing processes.
These platelets and growth factors, along with a fluid portion of blood called plasma, are then injected back into the person at the site of their injury. The injection contains a number of proteins that can potentially decrease inflammation, reduce pain and improve tissue healing. PRP has been used for many soft-tissue injuries, including those in ligaments, tendons, knee menisci, cartilage and muscle. As with all autologous regenerative medicine, PRP is generally safe, since it is a therapy derived from the patient’s own blood.
