PRP stands for platelet-rich plasma. A PRP injection is a procedure where blood is drawn from the patient and spun in a centrifuge to separate the plasma from the whole blood. The plasma portion of the blood includes a high concentration of platelets, which contain many growth factors and are important in the healing process. The plasma can then be injected into the patient at the site of injury. The platelets have been shown to enhance the body’s own natural ability to heal, which in turn will decrease symptoms.

Examples of diagnoses where a PRP injection may be offered for include arthritis, rotator cuff tear or tendonitis, MCL sprain, UCL sprain, or lateral epicondylitis (tennis elbow).
