It has been quite a while since the last update. I am very happy to say that Sophie has made a complete recovery. For the first winter after her surgery she was a bit lame some days, it seemed the cold weather (although it was not cold in the house) made her stiff or aggravated arthritis likely present in the knee. All summer and now into the fall her knee has been wonderful. She still does not seem to be symptomatic in her hips. Her unaffected knee has held up and we seem to have dodged the bullet of the good knee failing.As you can see in the photos, she is unrestricted in her movement.
She is 6.5 years old in these photos and seems to prematurely show her age. She has definitely slowed down a little bit, but still gets crazy and playful when she feels excited. When outside she will still chase a ball for as long as I let her.
Here are a couple of videos of Sophie's gait in March 2009, nearly 1 year post-op:
