I think you're wrong. I've been running with good form, proper nutrition, and rest, for over 40 years, averaging 20-30 miles a week, and have absolutely zero knee issues.

I think you're running a risk here of turning more people off from running, and doing more harm than good, by warning people of a risk that while possible, is unlikely to affect them.

Generally these types of degenerative conditions have other underlying conditions driving them, and are not simply the result of running. We are born to move.
