A medical reporter from the New York Times just wrote an article about platelet rich plasma for her hamstring injury. Below is her part of her story:
"From what they see in patients with injuries like mine, he said, the doctors are enthusiastic. “The results over all are so promising and so positive,” (her doctor told her) As a skeptical medical reporter, I’d say, that’s not very convincing evidence. As an injured runner, I say, “I’ll take it.”
As the data surrounding platelet rich plasma matures and is published widely, we will be able to answer her questions better about how and when to use PRP most appropriately. For now, however, it is indeed a reasonable treatment for patients with chronic severe tendiniopathy.
