Does the plantar plate need to "heal” on MRI before I can run?

I was recently doing a call with an athlete who has a sprain of the plantar plate ligament. 

One of the things that happens with runners is we get an MRI, sometimes just for what we suspect is a plantar plate sprain. 

He went and got an MRI. In fact, he got a couple of MRIs. The MRIs were different. 

It is reasonable to want reassurance that your foot is healing before you start running. But an MRI doesn't always provide the reassurance you seek. 

Today on the Doc On The Run podcast we are  talking about whether or not you need to see healing of the plantar plate ligament on your MRI before you can run.
