Anyone ever have a "full-thickness fissure" in their cartilage?

I’ve got an appointment on Wed. morning with my orthopedic MD. Those guys are usually super-busy so I’m probably not going to have much face-to-face time with him. Just wondering if there are some good “non-obvious” questions or things I should know so I can make the most of the time I have with the guy. I imagine he’ll explain the problem and go over treatments and recovery and what insurance will/won’t pay for. Maybe there are other questions worth asking?

In my very brief consult with Dr. Google it sounds like regenerative medicine may be one approach—in some cases. Do any of you have experiences (good or bad) with regenerative medicine?
