Anecdotal data: two years ago I was diagnosed with osteoarthritis stage four and told I needed surgery immediately. I spent months researching studies on osteoarthritis. What I found is that switching exercise from golf to cycling, stopping running and other impact exercises, generally following some of the rules of the anti-inflammatory index diet, and taking supplements has entirely removed my pain and I am fully functional for daily activities. There are a couple of specific moves I avoid (touching my knee close to my chest or turning my toes very sharply in or out) as those can cause some minor discomfort. I take no medications, and have had no surgeries. This was after every surgeon I spoke to wanted to book a hip replacement immediately.
I also ate tons of honey.
