According to Brian Halpern, MD, a sports-medicine specialist at Hospital for Special Surgery, "Tendon and ligament healing relies on adequate blood supply and cellular migration. Platelet-derived growth factors are critically involved in this process."
Platelet rich plasma (PRP) injections help the body regenerate and heal by harnessing these growth factors. To obtain the PRP, a small amount of a patient's own blood is drawn. The blood is then spun down in a centrifuge for a few minutes, which isolates the PRP with growth factors. The PRP isolate is then injected back into the injured area. The goal is to enhance the healing environment by concentrating the essential components of repair from the patient's own blood, thus limiting side effects and facilitating healing.
What is most exciting is that these injections aren't just reserved for professional athletes. Tendinitis affects just about everyone at sometime in their life. Whether it's the rotator cuff, patellar tendon, or tennis elbow, tendinitis is usually the result of overuse of the affected tendon. Usually the condition is temporary and can be easily relieved with rest, ice, and the use of inflammatory medicines (such as Ibuprofen). Sometimes physical therapy and/or cortisone injections are necessary. That being said, there are times when the pain persists. According to Halpern, "It can seem crippling to the sufferer, and when the pain and dysfunction reach that point, a high-tech answer in the form of PRP is available for suitable patients."
It is quite possible that in the near future, PRP injections will become a routine part of the treatment algorithm for tendinitis. "In patients who fail to respond to anti-inflammatory medications and physical therapy, an injection of PRP may save patients a trip to the operating room," adds Dr. Halpern. "The future looks very promising as we attempt to concentrate these biologically active growth factors at the bedside to help patients in pain. Allowing the body to heal itself is not just logical. ...It is very effective."
