Platelet Rich Plasma is blood that contains a concentrated source of autologous platelets. The platelets collected in PRP are activated by adding thrombin and calcium chloride which induces the release of these factors by degranulation of the alpha granules produced. Several forms of PRP-derived products exist for different conditions. PRP can be liquid, or gel formed but a fibrin matrix is often used for meniscus repair, rotator cuff injury, and ACL reconstruction. PRP contains stem cells that are concentrated which allows for cell division for growth as well as being able to attract additional stem cells to the repair site. Regeneration occurs within the tissues and fibrils ensues while initiating growth and repair for up to 1 month after these injections. The result is new, healthy tissue that is permanent and is used aesthetically or medically dependent upon patient presentation.
