I had mine this past monday!!! Had it on the other knee, two years ago!
It's really not bad. Way better than a knee replacement!!!
The one thing to remember though...is there are no two knees the same, each surgery is different in what they find....do not pay attention to what people say about theirs...each one is different!!!! Some will go to work the next week, otheers may need physio!
Good luck.
