Other Exercise: Depending on your location, swimming is often a good choice for aerobic exercise to keep heart healthy when walking is not an option. Arm exercises like placing a bicycle upside down and using the foot pedals with the hands also can be done. Lastly, check to see if knee problems could be easily helped with medications, injection, or minor operations. Good luck; I'm glad you care about your dad!
