Understanding Platelet Rich Plasma Injections Platelet rich plasma (PRP) is used commonly in orthopedic procedures and carries a wide variety of indications. PRP has been studied for use in tendinopathy, muscle strains, and osteoarthritis. The purpose of this review is to understand the different formulations and nuances in terminology associated with PRP injections.
Process Platelet rich plasma is obtained through a venous blood draw. The whole blood is then processed through a centrifuge system to obtain a higher concentration of platelets. The rationale for obtaining the higher concentration of platelets is that the platelet rich portion contains high values of growth factor and cytokines.
Studies have identified vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), interleukin-10, and tumor-necrosis factor B in PRP preparations. Each growth factor plays a different role in the anti-inflammatory cascade. VEGF plays a role in angiogenesis, FGF can stimulate fibroblast to create collagenase, and insulin-like growth factor can support collagen.
In tendons, the cellular migration, angiogenesis, and cellular proliferation can increase tenocyte proliferation. Role of PRP on tendons There is no uniform standardization for PRP. The processing of the PRP can vary widely.
The final processed PRP product can have different platelet concentrations and varying levels of leukocytes. The top layer of the centrifuged product is plasma, the middle layer is the platelet and leukocyte portion, known as the buffy coat, and the bottom is the red blood cells. There is no consensus regarding the necessary platelet concentration for statistical benefit.
If you are experiencing symptoms that may be related to prp (platelet rich plasma), it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
