I would recommend trying it yourself. I always had problems with my knees, wrists and elbows to the point where pretty much any kind of exercise caused lot of pain. Then I spent a month at a yoga ashram where all food was made fresh without any sugar. After two weeks the joint pain was almost completely gone.
I am now on a low-sugar diet and my joints are still doing well. When I eat some sugar after half an hour my wrist and elbow start to hurt again.
I have tried this a few times and the effect is totally reproducible. This experience makes me wonder how many people who have arthritis and other inflammatory diseases could reduce their symptoms with a low/no sugar diet.
Keeping weight off is also much easier with low sugar.
My advice is: Keep it a try. Stay off sugar for a month and see if you notice any changes. There is nothing to lose (besides a few pounds).
