PRP science explained. PRP vs. Corticosteroid vs. Placebo injections.

If you are a runner with a painful tendon or ligament issue like chronic plantar fasciitis, Achilles tendonitis or plantar plate sprain that just won't get better, you might have done some research into injections and found a thing called a PRP or "platelet-rich plasma injection." The way that PRP injections are marketed by some doctors, you might think that it's mostly unicorns and fairy dust, but there is some actual science behind platelet-rich plasma.  and the effect that it can have on these tendons and ligaments that aren't healing very well.  Corticosteroid injections have also been around for a much longer time.  Both types of injections can be used as treatments for tendon and ligament sprains in runners. The question is whether or not there is any real scientific evidence to support Platelet Rich Plasma injection or Corticosteroid injections for chronic tendon or ligament injuries. Is one injection any better than the other? PRP science explained. Is there a difference between PRP injections, corticosteroid injections, and placebo?  That's what we're talking about today on the Doc On The Run Podcast.
