In my opinion, always opt for the least invasive thing possible...bodies don't react well to invasive surgery. Leveling the tibial plateau sounds pretty damn harsh, don't you think it would cause osteoarthritis later on? Also, what do they do with the meniscus that's attached to the tibia. do they remove it, shave down the tibia, and reattach the meniscus? all that vs. something that is routinely done? sounds like they're using dogs as guiny pigs on a new surgery for humans. and "CCL" what colateral is that? do you mean LCL or MCL? if so those aren't that deep so the surgery wouldn't be that complicated.
what were the potential drawbacks for the "CCL??" surgery, you didn't list any.
