Platelet Rich Plasma (PRP) Therapy for knee injuries uses parts of your own blood to help the body heal itself. A sample of your blood is spun in a centrifuge to separate out the platelets, which is then concentrated and mixed with plasma. The doctor injects this PRP mixture into the damaged tissues. Your body’s immune system reacts to help repair and rebuild the damaged tissues.
