Biking is a great strength enhancer for running and sprints will have a dramatic impact on your cardio capacity. However, improper form will exagerate knees problems. I switched from roadie to MB and then to MB racing (cross-country). MB has less knee related injuries because of the shifting angles and changing of pace from my experience.

I use an elyptical to push through injuries. Between the low impact and reversing ability (quad buster), it will allow you to maintain strength and cardio while allowing the knees to heal. Again, proper technique is critical.

Do you have the right running shoes? I thought I did for years until I went to a running store and allowed them to recommend based on my mileage, style, and foot. Surpirisingly, the recommended shoe was a Mizuno and ended up cheaper than my stand-bys I have worn for years (Nike Air line). No ankle, back or knees flare ups and they have lasted longer (200 plus miles). This is not a plug for Mizuno, but the fact that I would have never entertained them without the full foot profile.

Some things to consider.
