Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
If this ACL rupture was due to an injury, there is no reason to believe that the other knee will require this procedure. There are cases where this can be a hereditary condition and the other knee may rupture at some point in time but this is not always the case. Unless there is evidence that the other knee is in danger of rupturing, then it is best to do one. It appears, in your case, that this is not the case and I would recommend only doing the one knee and waiting until there is an issue with the other knee which may never happen.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
