Starfish, I can empathize with your health issues. Part of the reason I haven't been riding as much as I used to is because I have a really bad knee. I've visited 2 orthos this last year to get an opinion and they both said I'm really limited with options other than a total knee replacement in the near future. But being the stubborn gal that I am, I'm determined to keep my original equipment, even if the warranty has expired.

So far I haven't had knee problems. I am actually more concerned with my good knee because of over-compensation. I'm fortunate that the LBS has access to a young prominent orthopedist that is a pro cyclist and I can meet with him to see if I need to shim one of my shoes as well as fine tune my fit.

Prior to cycling (just within the past 3 weeks) I walked the dogs 45 minutes most evenings. That was about all other than riding my bike on the trainer occasionally. My dogs take me for a brisk walk so I'm getting a good cardio workout. Now if I can get them to pull me on the recumbent, lol.
