So I gave up running and started cycling almost five years ago, and I have minimal knee pain since then. I think the cycling actually helps my knees by flaxing them without the impact of running, or even walking. (I get knee stiffness and soreness even from long walks, but not from cycling.) Are you sure the cycling is hurting your knee, or could it be other activities? Meanwhile, I know many people who have had knee replacements and are doing well with them so if it comes to that, it's not necessarily a bad situation. In my case, I feel that cycling has kept me from having to have a knee replacement.
