I've found that medical options are most effective for osteoarthritis. What surgical options are you talking about? There are many procedure and they have different indications and results.
I'd get a diagnosis first, X-Rays are probably indicated then discuss this with your vet.
As many have said, glucosamine/chondroitin supplements (there are many that are effective) and nSAIDS are the place to start and in a huge majority of cases will keep a dog relatively pain free for years.
Life style changes can be helpful (like doxiemom11 recommended), maintaining muscle tone and optimum weight.
PM me if you have any specific questions.
