Patient discussion about meniscus

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?

A. The recovery process is individual, and you cannot predict it in advance. I know someone who has done it and was able to go back to exercising regularly after 2 months. 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.
