What is wrong if your right knee is bone on bone but you can walk for hours in a mall or a park but using a treadmill for 15 minutes makes it swell and ache for days and how can you get exercise?

Answer 1

Your question interested me because I too have a right knee that is bone on bone. The consistency and speed of the treadmill causes alot of stress on the knee. The constant pounding of each step makes your workout high impact on the knee joing. You are probably not walking with the same consistent speed while in the mall. Make sure you have a good shoe for exercise (I like Nike Shox). I play tennis and sometimes will experience an extremely sore knee, other times it won't bother me at all. Ice your knee after using the treadmill or anytime it gets real sore. I like to ice my knee for 20 minutes and then a nice hot bubble bath helps. I have used anti-inflammatories only when I can't stand the pain. You may want to try a stationary bike, or stairmaster which has less impact on your knee. You may also need to build up the muscles around your bad knee so hitting the weights would be beneficial. Leg extensions and leg curls are good ones to do.

You may have to have a knee replacement done.
