Full shoulder replacement

I’m  71 years old and still love climbing. I was just told that I have “ bone on bone” in my left shoulder joint. My sports medicine Dr has suggested that a reverse shoulder replacement would be necessary. From what I’ve read rock climbing is not advisable after the surgery. I don’t want to quit !  Your thoughts ?

Do a google search for Chuck Odette. He just had a reverse shoulder and is back to climbing.
And is a pretty inspiring figure for folks our age.

I'm 70, had both shoulders replaced this year, left in January and right in April.  Both were anatomic replacements with Enovis Altivate stemless implants.  Didn't climb for six months, been back climbing in the gym for about five months.  It is going well.  Climbing around 11a/11b, getting stronger and progressively less discomfort.  Certainly glad I had the surgery.  Shoulders had severe osteoarthritis with painfull grinding and shifting of the joint and increasingly limited range of motion.  The fake shoulder sockets are incredibly smooth and pain free, what discomfort and range of motion issues there are come from the rotator cuff muscles getting used to the new arrangement.  The surgery and recovery were not all that painful, just boring for a few months.  They don't want you to put too much strain on the subscapularis tendon while it reattaches to the humeral head, so PT is mainly light range of motion for the first 12 weeks.  If your shoulders are getting bad I would suggest going ahead and having the replacement.  I am enjoying climbing a lot more now than before the surgery.  Having an anatomic replacement with a stemless implant may be more conducive to a return to climbing.  Whatever your decision, good luck with it.  

Just do it. Replacement is a cure for your condition - according to my doc.
I‘m 73, been climbing 8+ years on a full shoulder replacement - as well as I ever have (mediocre;-) and better than I could have ever hoped for. Oh, it’s all about the PT. Good Luck. 

The reverse total shoulder is the option for when the rotator cuff is not functional so anatomical vs reverse depends on the condition of the cuff.
the point of a joint replacement is to move more comfortably and be able to do what you want to do. Following the rehabilitation protocol, especially early on and not rushing it is crucial. 

Thank you all for your replies. I feel much better about my circumstances now.
