Excellent idea. That disagreement is surely cause for concern. If you do get a replacement, be aware the recovery time is almost twice as long as an r/c repair. Most tears are repairable by making 3 short incisions and inserting thin precision instruments and a camera. That is painful as hell, especially the first 24-48 hours. Recovery is very quick compared to open surgery since the healing is only in a handful of small areas. If you stick to the doctor’s orders, you can be good as new in less than a year. Healing time varies, due in great part to how hard you work your shoulder during the long months of healing.
My replacement surgery was the single most painful experience of my life, more than even kidney stones (2nd most painful!). There was an insurance problem with some of my pain meds. I ended up with the most painful weekend I ever spent as well. If you get replacement surgery, make sure you and your doctor get your medications worked out before your surgery and you’ll be fine.
Stick to your doctor’s orders and it will still be 2 years until you can say your shoulder feels normal.
I had my reverse shoulder done in October 2014. The only thing about it I don’t like is I have very limited movement behind my back, due to the shape of the reverse joint, other than that, I have very good movement with that arm.
Sorry to disagree @Kraven, but while you can be fucked for life from shoulder being cut open, there is no guarantee the fix will last for life. Both of my r/c repairs failed to provide lifelong relief. The left shoulder repair lasted 2 years. Just before the repair on my right shoulder I got a fresh tear in the left, less than a year, the right shoulder tore again
