Are calcified Achilles tendons more prone to rupture in runners?

Today's episode comes from a question from one of the YouTube viewers. The specific question was, are calcified Achilles tendons more prone to tendon rupture in runners? That's a great question. I think if you ask most doctors, their answer is probably going to be yes. But since I got this very specific question, I actually wanted to see if there is any research that truly proves whether or not Achilles tendons that have calcification or ossification within them, whether or not they're actually more prone to rupture in runners. Are calcified Achilles tendons more prone to rupture in runners? Well, that's what we're going to talk about today on the Doc On The Run Podcast.
