KA might not have been allowed to do that without John’s permission. It sounds like John has decided to share them himself now?
I still don’t understand what other teams would need to see. It’s been public for a long time now what’s wrong with John, and what the available options for treatment are. Do they expect to see some shocking new detail in an X-Ray that multiple medical experts missed?
I doubt medical records are the reason John hasn’t been traded, it’s the fact that he hasn’t gotten fixed.
