Kathy, that is wild. Most people told me based on my symptoms that I had miniscus. If that had been the problem, they would have scheduled arthroscopic surgery and taken care of it soon after discovery. They said that the cartilidge is gone (miniscus), but that it couldn't be repaired because with the arthrosis, it would just tear again. They said the bike (with no or minimal resistance), actually keeps the joint lubricated so that it doesn't stiffen up.

Who knows. All I know is that it is feeling much better and I am walking again. Even walked 30 minutes on the treadmill this morning. Not fast (only 2.5 mph) but at least I was walking.
