If you have cut your finger or hand, you may have experienced a wound that closes, forms a scab and eventually heals back to normal. In fact, platelets in the blood play an important role in this healing process. Therefore, if platelets are low, it is difficult to stop the bleeding and wounds heal more slowly. Also, when you have a bruise or sprain, the injured area may swell, and this swelling is due to bleeding under the skin. In bruises and sprains, as with cuts to the skin, platelets supply substances (growth factors) that promote the repair of damaged tissue, and the self-healing mechanism works to restore the damaged tissue to its original state.
PRP therapy is a treatment that is frequently used in Europe and the USA as a treatment to support this ""power to heal oneself (self-healing power)"". The patient takes approximately 20 litres of his or her own blood and, using a special technique, extracts only the platelet-rich part of the blood to create autologous PRP. This PRP is rich in growth factors, so injecting it into the damaged area of the body can be expected to promote tissue repair in that area, resulting in "faster healing" and "less pain".
