Platelet Rich Plasma (PRP) is a blood product used to promote homeostasis and wound repair in oral, maxillofacial, plastic, reconstructive and orthopedic surgery. In a recent study by researchers at Stanford University, it was reported to help with tendon repair by accelerating healing.
PRP is a product derived from your own blood. A small amount of your blood (usually 20-50cc) is drawn into a syringe. This is about the same or less than when you donate blood to the blood bank. It is separated into its components; red blood cells (RBC’s), platelet rich plasma, and plasma using a centrifuge. The platelet rich plasma is then separated and the balance of blood (RBC’s and plasma) are returned to you resulting in a volume loss of approximately 10 to 40cc.
PRP has been shown to contain at least five growth factors. The most important activities of these factors are to increase the healing cell population at the surgical site, stimulate blood vessel growth and promote hemostasis into the surgical site, stimulate blood vessel growth and promote homeostasis into the surgical site, increase the rate of wound healing and bone repair. The concentration of platelets in the PRP are responsible for the release of these growth factors resulting in a significant enhancement of wound healing and bone repair.
