This is the kind of negative support insurance companies like to use to charge you a little more for "questionable" treatments. I don't define "questionable" as 85% success, or as Pat says for the BHR, 96%. There is not a lot of question there that HR works and it works for most of us.
I think I need to understand the FDA's procedures and thresholds a little more, because it doesn't seem like there is enough negative data to say that HR is a problem, to the contrary, it seems like there is so much positive anecdotal and maybe even empirical data presenting the benefits of HR (I know I am looking at an HR website) that there wouldn't be much of a question.
I'll add to Pat's options, if you don't do HR and you don't do THR, you could take narcotics the rest of your life and stumble on the sidewalk, run from picnic tables, stop taking hikes with the family, put the bike away FOREVER,... I think everyone here agrees that 10 years or 15 years of having your life back is well worth the limited risk of having a failure. If you have a failure, you always have the option of THR and in some cases you might be able to do HR again.
