PRP works by recreating and stimulating the body’s own natural healing process. When tissue is injured, the body responds by sending specific ‘super healing’ cells types to the site of injury to start the regeneration of tissues. These ‘super healers’ are the platelets that contain growth factors that initiate repair and regeneration of new cells.
Usually in areas of the body that have a good blood supply with high cell turnover, the arteries will deliver platelets quickly to the injured tissue so that the healing and regeneration of new tissue can begin. This is similar to what occurs when you cut your skin and it bleeds. A clot forms and then it develops into a skin scab which later falls off revealing healed skin below.
The problem with some tissues including joint surfaces, tendons, bones, muscles, and some areas of skin is that they have a limited blood supply with a slow cell turnover and therefore heal slowly. These areas may require a helping hand to initiate the repair process, and this is where PRP therapy can help. PRP delivers the necessary growth factors and cells directly to the injured sites to regenerate the damaged tissues.
