Platelet-Rich Plasma (PRP) Injections
In recent years, doctors have learned that the body has the ability to heal itself. Platelet-rich plasma therapy is a form of regnerative medicine that can harness those abilities and amplify the natural growth factors your body uses to heal tissue.
What is plasma and what are platelets?
Plasma is the liquid portion of whole blood. It is composed largely of water and proteins, and it provides a medium for red blood cells, white blood cells and platelets to circulate through the body. Platelets, also called thrombocytes, are blood cells that cause blood clots and other necessary growth healing functions.
Platelet activation plays a key role in the body’s natural healing process.
What is platelet-rich plasma (PRP) and what are PRP injections?
Platelet-rich plasma (PRP) therapy uses injections of a concentration of a patient’s own platelets to accelerate the healing of injured tendons, ligaments, muscles and joints. In this way, PRP injections use each individual patient’s own healing system to improve musculoskeletal problems.
PRP injections are prepared by taking anywhere from one to a few tubes of your own blood and running it through a centrifuge to concentrate the platelets. These activated platelets are then injected directly into your injured or diseased body tissue. This releases growth factors that stimulate and increase the number of reparative cells your body produces.
Ultrasound imaging is sometimes used to guide the injection. The photographs below illustrate a PRP injection into a patient’s torn tendon. The ultrasound guidance is shown at left and the injection is shown at right.
