Thanks again to everyone who posted.
She did have surgery on both knees at the same time and is on pain meds, as well as antibiotic and joint supplement. It is VERY stressfull. She just pooped for the 1st time last night (thank god, after 7 days). Eating, drinking pretty good, and no problem w/ peeing but just looks so pitiful makes me want to cry

The doc didn't say anything about pinning the tibia. He deepened the groove, shortened and moved the placement of the ligament on the bone (is that pinning the tibia?).
I will search the site. I've already found the advice here helpful. Sunshine says 'thanks'

for your prayers and well wishes. I will post pictures soon.
