Just doing a memory dump so apologies for the randomness. Not saying it will be the same because I suspect there is a lot of variability, especially if there is are different procedures.
Had both knees scoped to clean up cartilage. 1st one was in 2003 and it was just a couple holes but it required a bit of PT to get my leg back to normal (strength, mobility, etc...) The second was a few years later in 2006 and it seemed to be a lot less recovery. Neither were very painful. Big thing to do is keep the swelling down because I think the quad can atrophy quickly. Walk as much as possible and permitted afterwards. Even if it hurts a little and you have to use a painkiller. The muscle keeps pumping and the blood flowing. It also actually helped me get the swelling down. Also, there is a tendency to sleep with the knee bent slightly rather than straight or elevated at an angle. I think that bend also lengthens recovery.
My biggest problem was walking down stairs afterwards. Going up was not that bad for me.
Hope it works out.
