I was just on a call with an injured runner who has been healing from a plantar plate sprain. If you have had one of these, you know they're problematic. The thing was that he asked me a question that really made me stop and think. What he asked was, “Is stress good or bad for the plantar plate ligament?” Well, that is what we're talking about today on the Doc On The Run Podcast.
