Radical new data on osteoarthritis from Paul Ingraham:
One of the deeply held beliefs in musculoskeletal medication is that osteoarthritis is a “put on and tear” situation — that joints slowly crumble below the onslaught of gravity and use and abuse. This basically mechanical view of arthritis immediately means that the heavier we’re, the extra possible we’re to have bother in our load-bearing joints.
However that’s simply not the case: osteoarthritis prevalence doubled within the 20th Century impartial of age and weight (Wallace 2017).
So one thing else must be happening. Individuals obtained heavier on common, however not twice as heavy!
Or think about this: overweight individuals get extra osteoarthritis of the hand (Jiang 2016), however in all probability not as a result of they’re strolling on their palms.
So … why?
This submit weaves collectively the threads of a number of previous posts concerning the biochemical foundations of seemingly “mechanical” issues, and you could acknowledge some items. However that is an all-new synthesis, anchored by some good science information you need to use — sensible and inspiring, which is a uncommon pleasure.
