Platelet rich plasma (PRP) is blood plasma with concentrated platelets that contain huge reserves of bioreactive proteins, including growth factors that are vital to initiate and accelerate tissue repair and regeneration. These bioreactive proteins promote connective tissue healing; bone, tendon, and ligament regeneration and repair; development of new blood vessels; and stimulate the wound healing process.
To perform PRP therapy, a small amount of blood is taken from the patient and placed in a centrifuge to increase the concentration of platelets and growth factors. The plasma created is injected directly into the damaged area.
Drexel Sports Medicine uses PRP therapy on an outpatient basis for the following conditions:
Most people require one platelet rich plasma treatment, although up to three sets of injections may be performed. Often the platelet rich plasma treatment is accompanied with a percutaneous tenotomy procedure at the same office visit if the injury is a chronic tendon problem. Subsequent treatments, if required, will be spaced approximately four to eight weeks apart. Short term recovery may take several weeks and maximal benefits may take several months, depending on the conditions being treated.
