The price of $1500 for a CCL tear indicates that this is not a boarded surgeon....or you are just getting a really good price.
I have an excellent surgeon in Houston who does stem cell ... but have not heard of it for LP. He is the one I use for all of my ortho issues with my pups and fosters. I am going to ask him out of curiosity.
Once these pups have a CCL tear there is a 50% increased chance of the second knee tearing.
