Why is PRP so painful?
Platelets release many chemicals that summon or call other reparative cells to the area of injury. When the platelets release their chemicals, it causes an inflammatory response. This inflammation is also why PRP injections into the tendons, muscles, and ligaments will hurt.
When was PRP first used?
The concept of PRP began in the 1970s in the field of hematology, which is the study of blood. This term was coined so that hematologists could define blood that had a higher platelet count than normal blood. This platelet-rich blood was mainly used for blood transfusions for individuals who suffered from low platelet count in their blood.

What is the History of Platelet-Rich Plasma - SRMC. Platelet-rich plasma, also known as PRP, contains a high concentration of growth factors and platelets. PRP that is used in regenerative medicine is autologous, meaning that it is generated from a person’s own body. About six percent of normal blood is made up of platelets.
What are the advantages of PRP?
One of the biggest advantages of PRP is that it is able to be delivered directly into the injury site. It is also easy to obtain, comes at a low price point, and comes with very few potential negative side effects. Because of these advantages, PRP can be used for many different medical treatments.
Platelet Rich Plasma referred to as Autologous

Why is plasma used?
Plasma is amazing because it is used in a lot of ways. Fresh frozen plasma helps in the treatment of people who have massive bleeding that results in shock— like seen in burns or those with trauma. It can also help in clotting especially in those suffering from massive internal bleeding or for people with clotting abnormalities.
Why are platelets important?
In simple words, they are important in maintaining balance to our body when problems arise. They also store antibacterial and even fungicidal proteins which help in activating other processes in the body that deals with inflammation. This is where the healing property of platelets lies — they help deal with the pain because they help with the inflammation and they facilitate the recovery of the body through the growth factors that are associated with healing.
How is plasma extracted?
Plasma can be extracted and separated by centrifugation which we will tackle later on. 55% of our blood is plasma and it is formed from the water and salt that has been absorbed by our stomach and intestines. The bone marrow, dead blood cells, and the other tissues of the body also help in the formation of plasma.
What are the proteins in a plasma?
It also has proteins like albumin and globulin that help maintain the balance in the blood. Sodium, potassium, bicarbonate, chloride, and calcium are also present in the plasma to help maintain the normal value of blood pH. Lastly, it also contains immunoglobulins that protect our body from both viral and bacterial infections.

What is PRP treatment?
Because the mechanisms of tendinopathy are not completely understood, the current treatment options for this tendon disease remain largely palliative. PRP is a popular cell-free therapy that is used worldwide to treat tendinopathy. Basic science studies have consistently shown the beneficial effects of PRP on tendons including increased tendon cell proliferation, increased expression of anabolic genes and proteins, and reduced tendon inflammation. However, the efficacy of PRP in clinical trials is not consistent leading to the controversies regarding the PRP treatment efficacy. Among clinical studies, RCTs are considered to be the gold standard in assessing the efficacy of PRP treatments in clinical settings. However, when an RCT study yields negative results on PRP treatment of tendinopathy, the reasons for the negative results should be carefully analyzed. A number of factors could cause the negative results in RCTs. The most common is the relatively small sample size. Considering the fact that the extremely variable responses of humans to any treatment are unavoidable, the use of a small number of subjects in an RCT study will surely reduce the statistical power to detect the treatment effects by PRP. Another major factor in RCTs is the undefined PRP composition in the preparations used in RCT studies. Most clinical studies use PRP, prepared from a commercial kit, and a predetermined dose is administered for all types of tendon injuries and all patients irrespective of age, gender, disease history, and so forth. Basic science studies on the other hand indicate that stem cells could be used to promote tendon wound healing only in early stages but not so effectively in later stages that may be dominated by the presence of degenerative tissues. Therefore, the so-called “one-size-fits-all” approach may be the main reason for the conflicting results observed in the PRP treatment of tendinopathy in clinical studies. Instead of this, we propose the use of an individualized approach based on the conditions of individual patients. Such efforts may improve the efficacy of PRP for the treatment of tendon injuries and may effectively address the controversies on the PRP treatment efficacy in clinical trials.
Why is PRP used in medicine?
PRP is safe because it is an autologous product derived from a patients' own blood and contains platelets and bioactive factors that can modify the biological microenvironment at injury sites, thus enhancing tissue healing. More importantly, PRP is not known to have any adverse effects unlike the commonly used nonsteroid anti-inflammatory drugs (NSAIDs) that are known to affect the gastrointestinal, cardiovascular, and renal systems [19, 20]. PRP is easy to use because of the simple preparation protocols; in fact, a number of PRP preparation kits are commercially available that are widely used in orthopaedic clinics. Besides, the application of PRP in the form of injections is also noninvasive and allows easy administration in clinical settings.
What is PRP used for?
Platelet-Rich Plasma (PRP) has been widely used in orthopaedic surgery and sport medicine to treat tendon injuries. However, the efficacy of PRP treatment for tendinopathy is controversial. This paper focuses on reviewing the basic science studies on PRP performed under well-controlled conditions. Bothin vitro andin vivo studies describe PRP's anabolic and anti-inflammatory effects on tendons. While some clinical trials support these findings, others refute them. In this review, we discuss the effectiveness of PRP to treat tendon injuries with evidence presented in basic science studies and the potential reasons for the controversial results in clinical trials. Finally, we comment on the approaches that may be required to improve the efficacy of PRP treatment for tendinopathy.
Does PRP increase inflammation?
However, leukocytes in PRP could potentially increase inflammation because they significantly increased the gene and protein expression of IL-1β, IL-6, and TNF-αin tendon cells [39]. This demonstrates that leukocytes can exacerbate inflammation in tendon cells but P-PRP without leukocytes can be anti-inflammatory because it decreased the gene expression of IL-6 when compared to untreated controls [39]. Similarly, PRP also reduced the gene expression and production of IL-6 in tendon cells when compared to cells treated with IL-1β[50]. It should be noted that IL-6 levels in tendon cells cultured in 2D and 3D hydrogels were increased by P-PRP [56]; therefore, future study may be still needed to determine the precise effects of P-PRP on IL-6. McCarrel et al. [45, 57] also showed that high concentration of leukocytes in PRP could induce higher expression of IL-1βand TNF-αwhen compared to P-PRP. Because platelets recruit leukocytes and progenitor cells to the sites of vascular injury and inflammation, they induce changes in cell permeability and promote chemotaxis and cell proliferation, which are essential steps in tissue repair. Macrophage, a kind of leukocyte, was reported to be involved in the maintenance of inflammatory state or innate immune response. It also induced tenocytes to synthesize relevant amounts of MCP-1/CCL2 and RANTES/CCL5, which could mediate migration of more monocytes/macrophages that can trigger inflammatory and angiogenic mechanisms [56, 58]. L-PRP can be directly involved in the inflammatory response by producing and releasing inflammatory mediators such as the cytokines, IL-1βand CD40L, and chemokines, CXCL1 and CCL2. Besides, PRP induces the expression of chemokine receptors, particularly CCR1, CCR3, CCR4, and CXCR4, thus regulating the inflammatory response associated with the healing process [55].
Does PRP affect tenocytes?
Pure-PRP has not been implicated in much catabolic activities while L-PRP is known to induce catabolic effects. Treatment of tenocytes with PRP, likely P-PRP, did not influence the catabolic molecules, MMP-3 and MMP-13 [41]. In fact, the expression of MMP-13 in tenocytes decreased after PRP treatmentin vitro, and the platelet concentration negatively correlated with MMP-3 and MMP-13 levels [46]. However, PRCR upregulated MMP-1 and MMP-3 expression [44] likely because of the presence of large amounts of leukocytes in PRCR. In a recent study, we showed that L-PRP significantly induced the expression of MMP-1 and MMP-13 while P-PRP only slightly increased the expression of MMP-1 when compared to the control [39]. These studies clearly indicate that leukocytes in PRP are the key factors that induce catabolic actions in tendons/tendon cells.
Does PRP help tendon healing?
Thus far, numerous basic science studies have shown the beneficial effects of PRP in healing tendon injuries. Specifically, growth factors in PRP have significantly enhanced the healing of tendon injuries such as tendinopathy [21–24]. These include PDGF, TGF-β, VEGF, EGF, IGF-I, FGF, and HGF [24–26]. When platelets are activated, not only are the growth factors released, but PRP also forms a fibrin gel, which provides a conducive bioscaffold for migrating cells thus incorporating new cells for tendon healing [27]. Therefore, PRP can be regarded as a promising treatment option for tendinopathy. However, the efficacy of PRP to treat tendinopathy in clinical trials is still controversial. Therefore, in this review we discuss evidence for the use of PRP presented in basic science studies conductedin vitroandin vivo under well-controlled conditions to determine the basis of PRP applications in clinical settings.
Does PRP affect collagen?
PRP not only affects collagen but also affects the expression of other tendon related genes and proteins. For example, PRP treatment increased the mRNA and protein expression of tenocyte-related genes (scleraxis (SCX) and tenascin-C) by activating the focal adhesion kinase (FAK) and extracellular-regulated kinase (ERK) 1/2 signaling pathways [43]. Furthermore, PRP treatment has been shown to enhance the expression of COMP, decorin, and tenascin-C [35, 42–46]. COMP is a tendon healing related glycoprotein, which is abundant in the normal tendon but is depleted in fibrous scar tissue. Decorin is a matrix proteoglycan and is also abundant in the tendon and plays a role in matrix assembly by binding to collagen type I fibrils. Tenascin-C is also a glycoprotein abundant in developing tendons. These noncollagenous matrix markers are the indicators of matrix synthesis, and an increase in their expression by PRP treatment also signifies the beneficial anabolic effects of PRP on tendons.
