In Obese Mice, Exercise Eases Arthritis, Even Without Weight Loss

Not ideal, but another argument in favor of training.
Adding another incentive to exercise, scientists at Duke University Medical Center have found that physical activity improves arthritis symptoms even among obese mice that continue to chow down on a high-fat diet.

However, the "excess weight," i.e., fatosity, almost certainly contributes.
