I had orthroscopic surgery when I was 13 because my knee cap would dislocate simultaniously. The doctor removed the pieces of broken cartliage and didn't realize how bad it was until he was perfoming the surgery. He told me, I would probablly need a full knee replacement within 10 years. I am now almost 21 years old, and have knee pain every day, and can feel and hear my knee grinding together when I lift it. I'm afraid to have a full replacement in fear that I may be worse off than I am now. Should I deal with the pain for now and wait until further damage occurs, or see a surgeon about the next possible step? Any advice would be greatly appreciated. Thanks. :)
