Is a cortisone injection malpractice if it causes a plantar fascia rupture in a runner?

I recently got a great question from a runner who was calling me for a second opinion during a telemedicine visit. She wanted to run but had a partial rupture in the plantar fascia. When we were talking about her history, she told me that she had had a couple of corticosteroid injections (or cortisone) injections for the plantar fascia when she had plantar fasciitis. Is a cortisone injection malpractice if it causes a plantar fascia rupture in a runner? Well, that's what we're talking about today on the Doc on the Run podcast.
