With all the activity happening in the world of sports, both domestically and abroad, there are bound to be an increasing number of injuries to tendons. Since your tendons connect your muscles to your bones they often take a significant amount of abuse and often show signs of wear and tear. Plantar fasciitis and even problems with the Achille’s Tendon are some issues involving your tendons that Podiatrists commonly diagnose and treat.

        When an injury occurs, the human body mounts a response to begin healing it immediately. In a case in which a tendon is torn, ruptured or strained, your platelets and other blood cells begin to work together to fix the damage.

        Although the platelets do cling together to form a platelet-plug and stop bleeding, they have been found to also secrete growth factors that promote wound healing and attract beneficial cells to the damaged area.

        Given the healing power of these tiny particles in our blood, doctors began performing Platelet-rich Plasma (PRP) injections in the late 1980’s to help patients in critical condition. The procedure is very simple and is explained below.

Step One: Blood is drawn from the patient. Not very much!

Step Two: The collected blood is placed in a centrifuge that concentrates the platelets and growth factors into a smaller amount of plasma.

Step Three: The Platelet-Rich Plasma is then carefully injected into the site around your injured tendon!

After the injections, you may experience some discomfort, but do not despair! Your body is reacting in the normal and desired way to the sudden influx of platelets and healing factors. You may want to ice and elevate your injury, perhaps even use Tylenol for pain relief. But ibuprofen, Advil and other NSAIDs will produce the opposite reaction that the procedure is trying to create.  

This treatment should be just a part of a rehabilitation planned by your doctors in order to get you back to your best. Finally, the PRP injection process may seem to be over-simplified, but it really is a very easy and effective way to treat tendonitis in all its forms.

****PRP injections routinely speed up the rate of healing in tendon-related injuries and are ever-increasing in their popularity amongst Sports Medicine physicians!****

Another impressive use for PRP injections is in the field of wound care. Patients with chronic wounds, diabetic or otherwise, often find that their physicians struggle with treating these persistent wounds and the subsequent infections and other issues. The processes that help with the tendonitis are the same ones that assist in the closing and healing of chronic wounds. The growth factors abundant in PRP are the perfect assistant to the struggling wound bed!

Much like the PRP injections, blood is taken from the patient and centrifuged into its components. The difference is that in the case of chronic wounds there is an open area that is not closing. The PRP is combined with an enzyme present in your body that works as a blood-clotting factor. This newly formed PRP gel can then be applied to the pesky wound and begin the task of laying down new collagens for healthy skin to grow over and promote new vasculature to feed the healing wound.

            Researchers are working around the clock to try to find new ways to heal the human body. From wound healing to cancer treatments, we as physicians are also working to facilitate the use of these new discoveries in the safest and most beneficial way possible for our patients. In the case of PRP treatments, it is the marriage of our human biology and physiology to the latest trends in medicine that allow us to provide excellent care to you and yours.
