Well, the good news is that Kaz's bone has compeletely healed. The bad news is that Dr. Lozier thinks her femur might need to be straightened. She is still showing signs of lameness in her left leg and Dr. Lozier attributes it to her slightly bowed femur. Of course, when they initially x-rayed her for the TPLO, she was 1/100th off of their measurements for suggesting femur straightening. We opted against the extra surgery because it sounded like she probably didn't need it.
There is still the possibility that after a few weeks of light walking, we will be able to build up the muscle and she will be strong enough to not need the femur straightening surgery. I'm not even 100% clear on what will happen to her if we don't get the surgery. It was a very frustrating visit to the vet after having so many good experiences.
My plan is to keep her on a muscle building program with 1/4-1/2 mile walks twice a day and an egg with her breakfast for added protein. We have another appointment with Dr. Lozier in 3 weeks and we will re-evaluate then. At this point, even if he suggests surgery, I think we will pass. As long as she's not in any pain, I don't think Kaz will mind if she has a funny gait. Currently, she is walking with a slight limp, but Dr. Lozier says she doesn't show any signs of discomfort when he extends her leg.
I think we would all be happier with a little bit of a limp instead of another invasive surgery with a 4 month recovery period and $1,500 price tag.
