Platelet-rich plasma consists of two elements: plasma, or the liquid portion of blood, and platelets, a type of blood cell that plays an important role in healing throughout the body. Platelets are well-known for their clotting abilities, but also contain growth factors that can trigger cell reproduction and stimulate tissue regeneration or healing in the treated area. 

​

To create platelet-rich plasma, clinicians take a blood sample from the patient and place it into a device called a centrifuge that rapidly spins the sample, separating out the other components of the blood from the platelets and concentrating them within the plasma.

​

After creating platelet-rich plasma from a patient’s blood sample, that solution is injected into the target area, such as an injured knee or a tendon.
