The prestigious Journal of the American Academy of Orthopaedic Surgeons (JAAOS) just published (Oct. 2009) a review article on the topic of platelet rich plasma (PRP). This represents an interesting and important milestone for PRP as a regenerative treatment. The article is well written and outlines the need for specificity in terms of platelet concentration and white blood cell concentration in clinical trials. Claims that 2x platelet concentration have the same clinical value as 4-6x are not supported by this article. Again, it is important to follow peer reviewed literature such as this over unsubstantiated marketing materials.
"(Platelet rich plasma's) use in sports medicine is growing given its potential to enhance muscle and tendon healing. In vitro studies suggest that growth factors released by platelets recruit reparative cells and may augment soft-tissue repair." From Hall et al. See full abstract.
