For whatever this is worth, my then 7 year-old lab/sheltie/border collie from a Menonite farm was limping a few years ago. Vet performed an arthrogram and diagnosed her with a partial ACL tear and gave me my ortho surgeon options. Not entirely sure how that diagnosis arises from a dog's arthrogram so I decided to watch it for a bit. 6 months later, no limping, no limitations and none since. I don't know how your dog was diagnosed but something to think about depending upon how much limping and limitation is happening.
