Welcome to the trashy knee club. I have really bad knees, I went to an ortho - as soon as he brought in the xrays of my knees to show me I said "Oh, that doesn't look right!" My kneecaps don't track right, and they make an amazing crunching sound. *BUT* the good news is, cycling is one of the best things you can do for knees. I take 3,000 mg of Glucosamine daily (OsteoBiFlex Triple strength) - it's supposed to help keep the joints lubricated. I honestly don't know if it works - doc says it couldn't hurt!

Remember when riding, to spin easily rather than grinding along, and try to avoid too much standing on the pedals, that adds pressure to the knees. If they're really hurting, I take Ibuprofin, just don't take it on an empty stomach.

If you are at a gym, talk to a trainer about the correct exercises to strengthen the muscles around your knees. My doc said avoid knee extensions and lunges, and no stairs!
