I don't have any experience with the surgery, but I have kind of a unique perspective. We recently adopted Simon, and he's eight. My vet strongly suspects that he had an ACL injury as a young dog that was left untreated (or treated conservatively, with no surgery). He definitely has issues with that leg and knee as an older dog. After a longer walk or too much running around the yard, his leg begins to tremble. He also gets more stiff on that side. Seeing him in some pain and not able to do everything he wants to makes me wish his prior owners had treated the injury when it occurred.
