Thanks everyone! I think the positive thoughts are helping!
I just heard from the surgeon and the good news is that the ligament is not torn. The bad news is that the cruciate ligament and the meniscus are a little "discolored". We'll have to wait for the biopsy results. In the meantime, Sasha's knee has been stabilized with a nylon (?) cord in the hopes of preventing further damage.
Sasha is in the recovery/ICU ward for now and won't get to come home for several days.
She is waking up though and did just fine in surgery.
Thanks again everyone! Please keep Sasha in your thoughts.
