A new study of platelet rich plasma (PRP) has found it to be ineffective in the treatment of Achilles tendonitis. PRP has been a popular treatment for a challenging set of conditions. Chronic types of tendonitis, including Achilles tendonitis, can be slow to heal, and prevent people from performing their favorite activities. PRP has gained popularity, not because it has been shown to be effective, but because it has been used by professional and elite athletes. Because of that, demand for PRP has grown significantly.
PRP uses the body's own cells to stimulate a healing response. Because the patient's own cells are used, side-effects are minimal, and risks are small. There has been hope that this treatment may be the answer to several chronic conditions, but this new study does not appear promising.
