Do arthritis injections work for elderly dogs with severe arthritis? - arthritis injections

My dog collie mix, the many problems with his hind legs. I brought to the vet and they gave me suppliments vitamins, analgesics, etc.. It has something that worked for a while. But now he is so weak that I should help lower the 2 small steps outside toilet, and again when it is done. I do not know what to do if the hind legs are completely will not be long for this step would be. I've heard that a certain kind of shots that can give it to the vet, would help. Has anyone heard of it? And you know the results of these treatments?
Thank you for listening. I am very worried for her. It has about 75 pounds and I can raise no more.
