Platelet Rich Plasma (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.

PRP is obtained by using the patient’s own blood similar to having one’s blood drawn for a lab test. That blood is then spun in a centrifuge to separate the red blood cells from the white blood cells and platelets. The platelets are then concentrated and injected back into the patient at the site of injury or pain. Platelets contain growth factors which are known to help with the healing process, making them the preferred part of the patient’s blood to use in treating their condition.

At this point, most insurance companies consider PRP injections experimental, as large research trials demonstrating the benefit, or lack thereof, have not been published. These injections are considered safe, however, as they are comprised of the patient’s own blood. The main potential complication is an infection from performing an injection, which occurs in less than 1% of all injections.
