Anyone here with a dog that has had a TPLO procedure?

My vet said it's pretty much 100% on the other knee going out... depending how active the dog is.. My beagle was up and running around the day after the operation.. they are insane dogs..
Yikes! None of the vets we've seen have given us odds or possibilities, but if that's the case, looks like I won't be insulating and building-out the shop/shed this summer after all.
