Platelet-Rich Plasma preparations are a type of injection that has quickly gained popularity over the past several years. Blood is a liquid made up of plasma, red blood cells, white blood cells and platelets. While platelets are well known for clotting blood, recent research suggests that they are also very important in healing injuries. Due to the nature of the way PRP is prepared, oftentimes these preparations can contain platelet concentrations five to ten times greater than usual. PRP is prepared by drawing blood from the patient and separating the platelets from the other blood components using a centrifuge. The separated platelets are then combined with remaining blood.
While the exact science behind PRP is still unknown, studies have shown healing processes to be expedited due to the increased concentration of platelets and growth factors. PRP can be used to inject injured areas or to facilitate the healing process after surgery.
