Surgically exposed Achilles tendon.
“Although somewhat ignored in tendons, every structure in our body (eg, nerves, muscles, joints, brain) has a total tissue pressure…”
I can’t really recommend actually reading this paper — it’s a slog, quite technical — so here is the cool gist of it: The pressure inside tendons has never really been studied, and it might be an important key to how tendinitis works and how to treat it. We certainly aren’t doing very well treating tendinopathy based on our current understanding! So clearly we need to understand it better, and this is a serious attempt to figure out how tendinopathy really works. Just basic science, with no real clinical implications yet. But maybe someday. I would love to see more like this.
