Abstract: | Plasma rich platelets (PRP) consist of blood plasma with a high concentration of platelets autologous constituting a huge reservoir of growth factors. The clinical use of the PRP is widespread in various medical applications. Even it is very popular with athletes, the use of PRP in tendinopathies is still scientifically discussed, particularly related to a disparity in the products called PRP. In order to optimize employment, it should be interested in the different stages of obtaining of the PRP. In this literature review, we analyzed in particular 8 parameters that can influence the quality of the PRP: (1) anticoagulants used to preserve the best feature of platelet; (2) centrifuge speeds used in order to extract platelets; (3) platelet concentrations and the presence of leukocytes and erythrocytes in the PRP; (4) the platelet activators for the mast of platelets and thus the release of growth factors; (5) use of local anesthetics to achieve infiltration, in addition to these parameters, it might be interesting to analyze other variables like: (6) employment or not of buffer to neutralize the acidity caused by anticoagulants; (7) injection under US guidance or not; and (8) volume of PRP injected to determine their influence on the healing potential. |
