I know that some similar surgery on the shoulder greatly improves movement and strength, but most people are afraid to do it and go through a big part of their lives struggling because they do not know about it. Research and find out more about it. It may be beneficial.
I reckon I get my aversion to medical treatment from my parents. Not that going more would help, but it seems that I more often look to avoid, even as I degrade further. Perhaps I should just go all in - a boob job and a Brazilian butt lift on top :D
Do it like a business transaction, benefits versus issues, left side/right side. But keep in mind that we recover much slower after 50. I needed 18 months to recover from an elbow problem. 18 fricking months. In my twenties, this should have been sorted in 3 weeks.
18 months! Damn! I won't do it if the risks are too high - because I have enough issues already. Though, the risks of not getting it sorted aren't great either.
In the end, It is all about your choice. What we could do 20 years ago is not a choice anymore now, it seems.
