My 85 lb lab had the extracapsular (fishing line) surgery done when she was 2.5 years old. It was about $1,200..pkg deal, follow-ups, meds, everything included. We went with the anti-inflammatories when it first happened (Thanksgiving day), and all seemed good until she landed funny while playing catch 4 months later. The vet, after the surgery, said she had 2 other ligament tears that seemed to be healing nicely, she had significant arthritic build-up (that he ground.scraped away), her meniscus was torn so he trimmed it, and her CCL was completely gone...he couldn't find one fiber of it. She broke the fishing line on the first one, but we didn't figure it out until 8+ months so he said to just watch it, so it took a little longer to heal that one (2 years before she quit limping).
She had the other knee done a couple years later. Different doctor did this one, and he used a different materia (no stretch), and a different binding pattern (Z-shape instead of the figure-8). This one only cost $825 or 850...only had one follow up with the doctor on that one (probably since we were old hands at the recovery this time). 6 months she was all good.
Everything is great now. For reference, this was a seriously active 2.5 year old puppy that I had to throw the ball to for 3+ hours a day to wear her out...of course this may have partially resulted in the injuries, developing bones and joints and all. And, she never slowed down or showed any pain, except for the limping/nnot-bearing weight. She limped out to the truck when we left the vet's office two hours after the surgery...I did pick her up and put her in the truck
.
ETA, she'll be nine in a couple weeks, so her knees are holding up pretty well.
Good luck.
