PRP Therapy Studies Show Mixed Results
The benefits of platelet-rich plasma (PRP) therapy are often touted by professional athletes as well as some healthcare professionals. The treatment, still not fully understood, can speed healing, especially for areas that are hard to heal, like tendons.
But a recent JAMA article cited a Dutch study that found PRP therapy was no more effective than placebo for patients with chronic Achilles' tendinopathy. Other studies, however, continue to extol its virtues. More studies are underway now to help sort out the uses for PRP therapy--it may be that some of the disconnect in conflicting studies has to do with the injury being treated.
Of course, the idea of treating a patient with his own plasma is appealing; this is certainly an area to continue watching.
