Given your personal experience, I expect you know significantly more than I do, but I just wanted to note: about 20 years ago, I was part of a small company that filmed and edited educational, medical videos for various clients. One of the main things we filmed for a while were Peyronies repair surgeries. They were using a product called Surgisis from Cook Medical as a tissue scaffold to straighten things out. It looks like, sometime in the past 20 years, Cook may have moved on to a new product called Biodesign: https://www.cookmedical.com/surgery/the-path-from-surgisis-t..., but I don't know anything about that.

You may know all of this already, and it may not be relevant to your situation at all, but in the slim hope that my experience of editing scores of Peyronies surgery videos may help nudge you in a new or helpful direction: there you have it!
