Hi Carolee~Welcome! I'm 58 with medical issues that prevent me from doing any impact exercising. I walk long distances but that may not be for you. Some ideas: an elliptical machine, bicycle (stationary or road), Nordic track, those type of machines. Maybe you could try different ones to see what you enjoy the most.
And a strong plug for water aerobics! My sister has severe rheumatoid and osteoarthritis and was over weight for many years. Once she retired, she became a water aerobics instructor! She gets cardio as well as strengthening, and has started walking 1-2 miles, often breaking it up into two short walks a day. She is 73 but seriously, she looks like she's in her 40s! She had to take the long view and realized that she would be stuck in a chair if she didn't get active. And believe me, she isn't one to sit for long!
With your bionic knees and soon to be bionic hip, you'll be unstoppable! Good luck and please keep us posted. You can do this!
