She should be ok to go. Monitor her exercise; don't let her over-do things.
Our dog had his cruciate done and went for hydro. He got over it very well, then bang! the other one went, due to over load from the 1st injury. Apparently, it's quite common for the other leg to go.
On a more upbeat note though he knew what was expected the 2nd time around and recovered far sooner without hydro.
He has the most buckled, clicky pair of back legs going, now both arthritic, so he has moderate exercise, a daily dose of Synflex (liquid glucosamine) & is kept away from damp weather.
He's a happy, contented little eleven year-old man, so long as he does everything in moderation. We can always tell if he's overdone things, as he becomes restless & unsettled because he's achy & uncomfortable. That's when I might be tempted to give him a Rimadyl.
