I would never feed any prescription food to a dog with joint issues, the bulk of those ingredients are highly inflammatory and will cause more harm than good. Feed a good quality raw diet (even premade raw will probably be cheaper than Hills), raw food contains natural sources of glucosamine/chondroitin from ground up cartilage. Lack of carbs will help with inflammation and pain reduction. You can also give her treats like tracheas and duck feet since those are good sources of glucosamine. I’ve had good results with a supplement called Liquid Health, its tasteless and easy to mix with ground raw food.
