PRP supports the self-healing processes of your body through the use of your own cells. Blood is mostly liquid (called plasma), but also contains solid components, including erythrocytes, leukocytes and platelets. Platelets are important for blood clotting, but they also contain proteins, called growth factors, which are important for healing injuries. They also contain exosomes that promote the local expression of stem cells.
With a higher concentration of growth factors than usual in blood, PRP injections help restore damaged tissue and inhibit painful inflammatory processes.
This treatment is extensively researched and supported in clinical trials. See our PRP evidence section.
