I have pups with luxating patellas and knock wood, not one has needed surgery for this condition.
The only time my vet and the orthopedic surgeon I use recommend surgery is when there are constant problems with limping and/or pain. Many yorkies live with luxating patellas all their lives and do not have issues.
You dont know what happened today and it sounds like she is a bit of a drama queen anyway? I say that because I have one of them.
Pups like that often don't need a lot to carry one. If she is not limping or having problems I would not be terribly concerned. LP is VERY common in yorkies!!
As for the surgery, if you ever do contemplate it, I highly recommend that you seek the advice of a board certified surgeon. You can find one in your area at:
www.acvs.org but your vet probably could refer you to one. Many pups have this surgery successfully.
