Leashed potty walks. You can sling them to keep weight off the leg for the first few days.
Martin had Bi-Lateral Extra-Capsular repair (meaning both knees done at the same time) almost one year ago to the day. I know exactly how you feel and how scary it is. I also know how good it feels to see them romp around again.
I used an x-pen instead of a crate, I wanted him to be able to turn and stretch out however he wanted, while controlling his activity.
What to expect- She will be out of it when you pick her up, the anesthesia makes them whiny as well. So you will be freaking out trying to decide if they are in pain or it's just the drugs wearing off. The first night and the next day are hell, as you try to over-analyze every breath and worry over the logistics of when to take them to the bathroom and how to do it.
Then it gets a LOT easier, becomes a routine. Then you are worried about keeping them quiet, even more fun.
Martin Day 1
The incision looks great
Day 2, looking better
Day 3, even better, killed a toy
Later in day 3 is when you call the surgeon in a panic, wanting to rush them in because the incision looks bad
Turns out, it's normal bruising and you are a worrywart/spaz, though they won't say that.
Day 4, leashed potty walk, no more sling
Likes to be outside just hanging out and watching things, figure it releives the boredom
Continues to work the crowd for any and all extra pets/scratches etc. that might be forthcoming....this surgery stuff isn't ALL bad
By day 9, can walk to the edge of the lawn, whoo hoo!!!
Life is good
In two months....

And this is a dog who had BOTH legs done.
Good luck!
