I have had a 'Scope on my right knee twice. Plus a reconstruction. The first time I was 16. The second I was 23, I think. One of my relatives just had one, she is almost 40.
Recovery time depends on the reason for your scope. Mine was mainly for my ACL, both times. I started physical therapy about 1 week later. Was able to do some slow stationary biking with no resistance by then. Within another week I could bike fairly quickly with no resistance. Walking without crutches about 2-3 weeks after surgery. From there I ramped up pretty quickly to being able to run, but then I was fairly young and in VERY good shape at that time. I would guess you will be able to get to at least biking fairly quickly.
My relative had a cartilage problem in her knee, I think. She started physical therapy the very next day! And her mobility came back much quicker then mine. She also was able to start biking right away, and was off crutches much sooner.
Obviously I am not a medical authority but it shouldn't set you back too far.
Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time. -Edison
