I had a meniscus tear a couple of years ago. I wasn't biking at the time so I can't tell you how it affected my riding. I can tell you however that biking has been the best way for me to work out. I have only just recently been able to run and not have a sharp knee pain. You will feel pressure and tightening even after everything heals depending on your physical activity. I was only at a 5 percent disability afterword. I will feel pressure in my knee after a hilly or harder ride. My left leg is also a bit weaker than my right as a result as well. Just more reason to ride. (edit) I also ride a single speed btw. No problems with it.
