Platelet-Rich Plasma.
/
Platelet-rich plasma (PRP) is a growing and robust therapeutic option in musculoskeletal medicine. PRP is a preparation of autologous plasma enriched with a platelet concentration above that normally contained in whole blood. The rationale for use and therapeutic potential of a high concentration of platelets is based on their capacity to supply supraphysiologic amounts of essential growth factors to provide a regenerative stimulus that promotes repair in tissues with low healing potential.
