Platelet Rich Plasma is prepared by centrifuging a small amount of a patient’s blood to obtain a platelet-rich sample. The platelets are activated and then injected under ultrasound or X-ray guidance. In most cases, the treatment can be completed in one session.
More than one course of PRP may be required and can be safely performed depending upon the response to the therapy and clinical indications.
The injection of your own platelets causes a local inflammatory reaction, releasing growth factors that stimulate healing and muscle regeneration, and limit the amount of scar tissue. PRP is also often used as part of stem cell treatment. Stem cells by themselves are limited in their ability to repair the injured area. For their maximal effect, stem cells have to be properly directed, and platelets perform this function. In effect, stem cells are construction workers and the platelets are their supervisors. Once they are activated, these stem cells perform a variety of valuable functions. Apart from repairing damage to the injured areas, they help damaged cells repair themselves and participate in the repairing process in a process called Immunomodulation.
The aftercare for most PRP injections is relatively simple. Patients resume activity at their own pace. The pain from the process typically will last a few days and sometimes rarely longer. Because your own blood is used, there is no risk of a transmittable infection and a very low risk of allergic reaction to the treatment.
