I'm glad that your daughter's surgery is over!
I'm having knee surgery next month (maybe sooner as the pain is getting ridiculous). I have cartiledge damage too and a meniscus problem after an injury (everyone thought it was just sprained until I went for an MRI

). If you don't mind sharing...did they mention how long her recovery should take? and is she going to have to be in PT at all? I ask cause I'm getting a bit anxious.
I hope she has a quick recovery!
