So sorry you are going through this. Please do LOTS of research before you agree to the surgery. We were pushed to do ACL surgery on one of ours but we decided to try a non surgical approach first. It worked and he is 100% now without any surgery. I am not saying to refuse the surgery but just keep in mind that surgeons are in the business of selling surgery and they rarely ever suggest less invasive options. Also (as you have learned) there are lots of complications that can arise and there are occasions where the surgery is unsuccessful. I don’t think many vets educate owners on the pros & cons.
The scariest thing with ligament injuries is that they cannot be seen on an x-ray. And MRIs are very expensive and not always that helpful. So until they open your dog up they really don’t know what they are dealing with. It’s truly a guessing game. Many vets diagnose a ligament injury just because that is what’s most common. Often they will open the dog up & find that the injury wasn’t that bad or possibly something else all together.
In our case all we did was give Trucker an anti-inflammatory (NSAID) / pain med (it was metacam) and then a few weeks of crate rest. His body built up scar tissue naturally and that stabilized his knee. I now supplement with fish oil & glucosamine/chondroitin.
I was not against the surgery but Trucker had just had surgery for something else & the thought of putting him through it all over again was heartbreaking. That is why I tried the alternate therapy 1st.
I figured if it didn’t work we could always do the surgery a little later. I am very glad that we waited. I know this may not be the answer for every dog but there really is no risk in waiting a short time (as long as you keep him calm & don’t further the injury). Of course our vet told us if we didn’t do the surgery immediately then he would blow out the other knee too. However that did not happen.

Again I am not telling you to go against your vet’s advice. I am only suggesting you do a little research & weigh all your options. You know your dog best so follow your instinct.
