I had my knee scoped three years ago for a torn miniscus. As far as my case goes, surgery did not add any recovery time, the injury itself dominated the recovery time. My surgery was out patient, I was in and out of the hospital in less than 4 hours. I had a follow up with my surgeon the next day so he could inspect the incisions, I went back to work after the follow up for the afternoon. I have a desk job though.
