Platelet-Rich Plasma (PRP) is produced from your own blood. Your blood is mainly a liquid called plasma, but also has white cells, red cells, and platelets in it. Platelets are the cells in our body that contain growth factors. These growth factors stimulate the healing process and are very important in the healing of injuries. PRP is plasma with an increased concentration of platelets.
To develop a PRP preparation, your blood is drawn. The blood is then placed in a special centrifugation machine. This machine separates the platelets from the rest of the blood. This concentrated form of platelets is called PRP. The PRP preparation is then injected into the injured area. Ultrasound is sometimes used to guide the injection of PRP.
