I have had 4 knee surgeries two each knee for torn meniscus, my dr told me I would never run again - HA, fooled him! I listened for a few years then decided to try it and I have NO problems. AFter my last knee surgery - about 3-4 days - I was on the bike at the gym pedaling slow and easy b/c the swelling wouldn't let me do more but I am here to tell you that was my last surgery and the fastest recovery! I was told the more you move it and resume normal activity the quicker the recovery.

You do have to listen to you knee and stop if you have pain but babying it is not the way to go, ICE, IBUPROFEN, AND ELEVATING for a few days is good, walking won't be fun but you can do it, heck I walked out of the hospital after the last one. biking was not painful and the easiest way to get the swelling down and ROM back. The only time I have knee pain now is when I pedal too hard in my big gears, then they ache all nite

I have no meniscus left in my left knee, I understand now they can regrow it or put something in there, maybe if I ever get better insurance I will have that done.

Good luck
