I don't fully trust Dr. de Bisschop's answers to my questions and I certainly don't trust his statistics. It is difficult even to get a straight answer about how severe and how long the post-operative restrictions are. His answers have ranged from being careful for two years to avoiding carrying heavy objects for one month.
On the French forum, there is a guy who had surgery with him a month ago named POLISERE - he is someone who had surgery before and is a re-op. It's kind of hard to figure out how he's doing because he mostly makes jokes and talks about how great some rehab center near Aubagne is

But he doesn't seem to be doing too badly in terms of post-operative symptoms.
I am still on the fence in regards to this surgery. On the one hand, I have no real confidence in its success. On the other hand, it does seem relatively non-invasive, and it does not cut any ligament or other structure really, and it's a small incision. If the French forum is not full of people who have been magically cured by de Bisschop, I have also seen no sign of people saying they have been harmed by him. If there is even a 15% or 20% chance of improving the symptoms I would do it -- as long as the chances of making them worse are close to 0%, and I could be working within 1 month and more or less back to my normal state of activity about 2 to 3 months afterwards. It is my uncertainty about the post-operative period and the lack of good information that gives me pause.
I have to decide somewhat soon because there is a "window of opportunity" between two jobs that I have in August, and if I don't do it now I will likely have to wait several years.
