If she's only hurting for 2 months out of the yr I would opt not doing surgery. I know every dog is different, ad YOU know her better than anyone!! Maybe u could call around and see if anyone does laser therapy there. Not a lot of vets are doing it yet but I really think in the near future a lot of clinics will start w the laser therapy. Lots of nfl, nbl etc are using the laser treatment for athletes as well
