Stay in lower gears and cycling actually makes knees better.

This corresponds with my experience.

Then why do so many cyclists develop patellofemoral syndrome?

How many is "so many"? Perhaps it actually developed before they became a
"cyclist".


Today, there is an
estimated 80 million cyclists in the
United States. Studies estimate that of
these 80 million, 48 percent experience
problems with their necks, 42 percent
knees, 36 percent groin and buttocks,
31 percent hands, and 30 percent back.
Regardless of what you intend to use a
bicycle for, there are some basic safety
principles you can implement to avoid
common cycling injuries.
