Aaron Carroll writes today that modern American medicine is even worse than you thought. It turns out there’s compelling evidence that arthroscopic knee surgery has no actual effect, but doctors keep doing it anyway. We could save money by just making a fake incision in your knee and doing physical therapy instead.

This made me wonder if I’ve been the victim of this dramatic placebo effect, since I had arthroscopic surgery on my knee about a decade ago and it worked great. But I guess not. My surgery was to repair a torn meniscus, and a torn meniscus is probably a very real thing. The useless variety of knee surgery is arthroscopic lavage, which is apparently a procedure that cleans out random crud from around your knee. Turns out the crud didn’t need to be removed, though. All these knees needed was ordinary physical therapy, which they’d get along with the surgery anyway.

Aaron’s point about this isn’t just that this is a pretty amazing result, but that it’s been largely ignored by both doctors and patients. Doctors still want to cut into knees and patients still want their knees cut into. Who wants a bunch of crud floating around in there, after all?

But now you know. If your doctor recommends arthroscopic lavage in the future, you’re going to turn it down. Right?

Right?

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
