What is platelet-rich plasma (PRP) and what are PRP injections?
Platelet-rich plasma (PRP) injections are a treatment option for patients with chronic injuries to the muscle, tendon or ligaments. Typically these injections are used once other treatment options, such as physical therapy, rest, and activity modification have failed.
Platelet-rich plasma therapy is a form of regenerative medicine that can harness those capabilities and amplify the natural growth factors your body uses to heal tissue.
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 reason blood clots and other necessary growth healing functions.
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.
PRP therapy is becoming a popular complement to hair transplants. PRP can help accelerate the growth of transplanted hair roots while also thickening existing hair.
