Thanks dogcatharmony!
Rainbow - I hope that Chase does not have to have another surgery on his first knee. I do know from my research that some dogs reject the plates or the screws and require it to be removed. I asked the vets at CSU about that and they said that while it is rare, it does happen and that there is no problem removing the plate after the bone has healed. Hazel also had some damage to her meniscus (understandable since the ACL probably ruptured at least a year before she was accurately diagnosed) but they cleaned it up during her TPLO.
for Chase!
