Patient discussion about duration

Q. I am scheduled for scope surgery for a torn meniscus on my knee and what is the duration for recovery? Has anyone had this surgery for a torn meniscus? How did you deal with this recovery?

I would think the recovery from the surgery itself is a matter of few weeks until you can walk properly, however you should still give your knee a break and rest for a while after.
