That is just a bummer. So that would mean you can never really ride a bike?

I know mine will say no more running because of knees issues. I keep trying, and I keep hurting. So I've learned to listen (cheat once in a while on treadmill but no more long stretches, just tiny steps running to avoid pounding. I find workarounds that satisfy me, and his recommendations.

Good luck. It sure sucks when you like an activity.
