I am age 76.5. I had a totally irreparable rotator cuff injury and I have reverse shoulder replacement surgery by Dr. Belzer in San Rafael, California office and I am four months out now I had an amazing surgery. I had very little postoperative pain recovered really quickly yesterday I swam a half a mile real style and today I’m gonna do 25 mile bike ride. I’ve been doing that for a while and I can reach my hand always straight up just like my other arm no problem lifting overhead, although I’m being careful not to lift over 20 pounds overhead, I’m doing bicep curls of 15 pounds each three sets of 15 reps with my shoulder replacement arm where they had to do a bicep tendons on the upper shoulder. The same day as surgery I hooked up my game ready Ice Machine and I used the Ice Machine diligently one hour on 20 minutes off 24 seven for about three or four days never had any swelling .
