I was dx with Chondromalacia last year I am petit in size. I am over 40yrs of age a female my doctor told me to lose some weight and my knee would get better. How long should I wait, because I’ve been small all my life and once I reach 40 I have gain a couple of pounds. Its giving me a lot of problems I purchased a knee brace to strenghten my musles in my knee. I haveproblems if I walk for a lenght of time, going up and downstairs, I also have swelling on the knee. Should I go back to my family doctor?
