Our last dog tore 2 ACLs, one at the age of about 5 years and one at the age of 14 years.
On the first ACL, we had the capsular surgery done. It was a long recovery, and we swore we would never put him through surgery again, but then at 14, he tore his other one. The one vet in town who does the capsule surgery did not think he was a good candidate, due to arthritis. Our local vet school was too backed up to see our dog, so we took him to an orthopedic veterinary surgeon in Jacksonville for a TPLO.
The surgeon said the decision whether or not to do the TPLO surgery was a "no-brainer." Well, our dog had the TPLO surgery and ended up with a lousy repair and osteomyelitis. He was in such terrible pain that he needed a Fentanyl patch. It was an awful, awful experience. We finally had him put down after he experienced a GI bleed in response to some of the antibiotics or pain meds he was on, about 3-4 months after surgery.
A customer of DH's has a Rottweiler who had an ACL tear several months ago. DH told him about our experience with our dog, and he did a lot of research and brought his Rottweiler to a vet who did a different kind of surgery (not the TPLO or capsular repair). He wasn't able to get the dog in for a couple of months, and meanwhile, the joint capsule repaired itself with scar tissue. The vet examined the dog, told DH's customer that all was well, and the dog did not need any surgery.
No, the ACL doesn't repair itself, but the neither the TPLO nor the capsular surgery repair the ACL either. Both surgeries are basically work-arounds.
Please be aware that if you choose the TPLO, the surgeon will cut into bone and put into metal hardware. This is MAJOR surgery and can have major complications.
Also, I would not board a dog at the vets post op. Our dog literally could not stand up and had to be held up to eat, drink, and do his business. Also, for the first several days I literally slept on the floor with him because he could not move around enough to do anything for himself, like get to his waterbowl.
The vet who did the TPLO surgery on our dog was also not very knowledgeable or caring about post-operative pain, and we ended up having to bring our dog to our own vet to get Tramadol in addition to the Rimadyl, and a Fentanyl patch when the Tramadol was not adequate. So you will need to be an advocate for your dog.
For both surgeries, including when our dog was much younger and had his first one, he really needed us around to take care of him. I don't think he could possibly get the kind of care while being boarded, unless your vet has an intensive-care kind of service (which is very expensive, nothing like the regular bill for boarding!) I would wait until you get back to have the surgery.
Your dog is young and healthy and I'm sure things will go well--I'm not trying to scare you--but for either surgery, the recovery period is very, very difficult for the dog and the dog's family!
