Overview of PRP
Of all the orthobiologic treatments, PRP has turned out to be the early star in the sports medicine world. It is affordable, low-risk, and effective. Platelet Rich Plasma (PRP) is derived from one’s own blood, and contains a supraphysiologic concentration of platelets, healing enzymes, and growth factors. Although platelets are usually thought of in the context of the clotting process of blood, PRP contains many biologic elements which are crucial to healing (VEGF, FGF, IGF, PDGF, and TGF). In general, tendons and other soft tissues have a poor blood supply, and this can limit their ability to heal. An injection of concentrated PRP can provide healing growth factors to the injured area (imagine one month’s worth of healing nutrients in a single injection).
