PRP or Platelet-rich Plasma therapy: How effective is it?

Blood is made up of plasma (liquid) and cells- red cells, white cells and platelets. Platelets play an important role in blood clotting. So when you get hurt, it is platelet which causes clotting of blood and stops the bleeding. Platelets also contain proteins called growth factors which are important for the healing process. PRP is the plasma with a higher concentration of platelets than what is normally found in the blood. To prepare PRP, blood is first drawn from the patient. Then this blood is put into a centrifuge device that spins at high speed. This process separates platelets from other components of blood. This plasma with a higher concentration of platelets is then injected to the patient. PRP injections into the damaged tissues stimulate your body to grow new cells and improve healing. How does PRP work? Since the concentration of platelets is higher in the PRP, even the concentration of growth factors is greater. Studies have shown that the higher concentration of growth factors can potentially enhance the healing process. PRP injections are given in 2 ways: A mixture of PRP and anesthetic drug is injected directly into the injured or inflamed part. Pain at the area of injection may temporarily increase, but it comes down slowly, and the patient may notice the beneficial effects of the injection in a few weeks. PRP is also used to improve healing after surgery. An athlete with completely torn tendon may require a surgery to repair the tendon. Healing of tendon can be improved by treating the injured area with PRP during surgery. What are the uses of PRP...
