What is platelet-rich plasma injection?

Platelet-rich plasma (PRP) injection is a medical treatment for orthopedic injuries and conditions. PRP is a form of your own blood that has a high concentration of cells called platelets. Platelets contain substances called growth factors that reduce pain and inflammation and enhance your body’s ability to heal itself. A PRP injection can eliminate the need for surgery for some people. 

PRP injections have been used to treat a range of conditions including those in the mouth and teeth, brain, eyes, genitourinary system, and cardiovascular system. PRP injections are currently most frequently used to treat orthopedic conditions, including osteoarthritis, tendinitis, and ligament tears.

PRP injection is only one method used to treat orthopedic injuries and conditions. Discuss all of your treatment options with your doctor to understand which options are right for you.   

Other procedures that may be performed

A PRP injection can be used by itself or with one or more complementary treatments, such as physical therapy and occupational therapy.
