We're talking about 2 different things. Joints are not just tendons and ligaments. Arthritis is significantly affected by mass.
I also want to be specific about my point. Bodyfat is important when it comes to joint health. The vast majority of people (1-2 STD above and below the median) will not achieve a BMI above 25 or 26 @ a lean body weight, lean being described as 12-13% or less for men. Anyone above this BMI is either, 1) carrying excess bodyfat and almost certainly negatively impacting their joints over the long term or 2) A genetic outlier in terms of muscular bodyweight (everyone thinks they are genetic outliers, but by definition almost no one is). 3) They are lean and high bodyweight and on steroids. I don't think I have to describe the potential confounding variables in this group.
So, if you are above 25-26 BMI, you are most likely fatter than you realize and thus are negatively impacting your joints more on the long term than you realize. If you are in group 2, I don't think there is any study that separates them from other groups. Physics would lead me to believe they are higher risk, but who knows. For group 3, there is so many confounding variables (training, effects of steroids on tendon/ligament strength, training methodology, etc) there would be no way to dial in on weight alone. Group 3 almost certainly sees more long-term joint damage than an average BW individual.
