PRP has also been demonstrated to improve function and reduce pain in people who have tendonitis or chronic tendinosis conditions such as tennis elbow or golfer's elbow. Some of the key advantages of PRP injections are that they can reduce the need for anti-inflammatories or stronger medications like opioids. Platelet-rich plasma (PRP) therapy uses injections of a concentration of a patient’s own platelets to accelerate the healing of injured tendons, ligaments, muscles and joints. In this way, PRP injections use each individual patient's own healing system to improve musculoskeletal problems. PRP injections are prepared by taking anywhere from one to a few tubes of your own blood and running it through a centrifuge to concentrate the platelets. These activated platelets are then injected directly into your injured or diseased body tissue. This releases growth factors that stimulate and increase the number of reparative cells your body produces. Ultrasound imaging is sometimes used to guide the injection. The photographs below illustrate a PRP injection into a patient's torn tendon. The ultrasound guidance is shown at left and the injection is shown at right.
Because PRP therapy involves injecting your own blood into your scalp, you aren’t at risk for getting a communicable disease.
Still, any therapy that involves injections always carries a risk of side effects such as:
There’s also the chance that you could have a negative reaction to the anesthetic used in the therapy. If you decide to pursue PRP therapy for hair loss, let your doctor know in advance about your tolerance to anesthetics.
