Just that, really. There is some sort of cartilage-related problem in my left knee that is very slowly healing (I hope). A month after the 'trauma', I can now walk without limping, but still can't go up or down stairs. I'm on an industrial strength anti-inflammatory, as well.
What can I do that will keep me in a reasonable state of fitness until I can run again?
Has anyone exercised with a bad knee without making it worse?
Cross trainer or 'moon walker' in the gym? I don't have a gym membership at the moment but will get one if someone here can give me hope that there are things I can do there with a bad knee.
