This is a great idea. I think it could build some interesting statistics over time. I too think it needs to be tweaked. The majority of the guys I've seen have a corrective procedure over the years didn't report pain free. I don't think you will get many votes on these terms.
At minimum, I would break down reversal, and de-nervation into 4 categories. Complete resolution, part resolution, no change, made me worse. The more procedures you offered that selection to, the better.
You could even do 5 categories. Complete resolution, much improved, part resolution, no change, made me worse.
Adding the word "Poll" to the title of the thread would be a great idea to. People would see it for years to come.
I will delete this post if you do it, lol
