Wow! I had no idea you were going through that. I hope it continues to go well. At our advanced ages, surgery is no walk in the park. I'm toying with the idea of knee surgery for an old motorcycle injury about 60 years ago. I was told it would give me problems later in life and sure enough, it is. Should be just arthroscopic though. Follow doctors orders and do your rehab as they tell you to. You'll be up and around in no time. Prayers for you though.
