I can't remember where i read it, but today i felt a slight twinge in my knees, and looked down to see a bow-legged position, which i promptly changed to cycling with my legs as close to the top--tube as possible. The next 25 miles were fine.
So maybe the way in which you ride might be changed.
I don't know though, and one problem with joints (esp. knees) is that everyone's reaction is different.
