My husband has a shoulder that hurts all the time with significant arthritis, bone on bone thickened rotator cuff etc. Surgeon who only does shoulders and has excellent reputation has recommended reverse replacement. After a stroke last March he has no physical impairment but cognitive impairment so the decision is up to me. He wants the replacement but I'm not sure he fully understands that it is not guaranteed. He has had both knees and a hip replaced previously so he is no stranger to rehab. He is 80 but still works out and until the shoulder played golf. I am worried because of a heart condition and the stroke history but also worried that if it is not done he will lose ability to be physically active. He is on blood thinners that will need to be stopped. If anyone with complex conditions has had a replacement I'd certainly appreciate feedback including encouragement or an opinion to not take the chance. Thanks in advance.
