I'm a cardiologist. Four surgeries that millions of people have undergone work no better than fake surgery — where the surgeon cuts the skin, pretends to operate, sews you back up, and does nothing else. The patients who got the fake operation improved just as much as the ones who got the real one. This isn't fringe skepticism. It's from rigorous, blinded, randomized trials in the New England Journal of Medicine and the BMJ. And it reveals something profound about the human body — and about how much of medicine is ritual. Here's what the sham-controlled trials actually found: 𝗞𝗻𝗲𝗲 𝗮𝗿𝘁𝗵𝗿𝗼𝘀𝗰𝗼𝗽𝘆 𝗳𝗼𝗿 𝗮𝗿𝘁𝗵𝗿𝗶𝘁𝗶𝘀. A landmark 2002 trial randomized patients to real "cleanout" surgery or fake surgery — skin incisions only, no actual procedure. Two years later, pain and walking ability were identical across groups. This was one of the most common orthopedic operations in America — hundreds of thousands a year, over a billion dollars. Guidelines now advise against it. The improvement was real. The scraping had nothing to do with it. 𝗠𝗲𝗻𝗶𝘀𝗰𝘂𝘀 𝘀𝘂𝗿𝗴𝗲𝗿𝘆 𝗳𝗼𝗿 𝗱𝗲𝗴𝗲𝗻𝗲𝗿𝗮𝘁𝗶𝘃𝗲 𝘁𝗲𝗮𝗿𝘀. The 2013 Finnish FIDELITY trial compared real meniscus trimming to sham surgery. One year later, the results were the same. This was historically one of the most performed operations on earth — around 700,000 a year in the US. And later data suggests the real surgery may actually accelerate arthritis in some patients. 𝗦𝗵𝗼𝘂𝗹𝗱𝗲𝗿 𝗱𝗲𝗰𝗼𝗺𝗽𝗿𝗲𝘀𝘀𝗶𝗼𝗻 𝗳𝗼𝗿 𝗶𝗺𝗽𝗶𝗻𝗴𝗲𝗺𝗲𝗻𝘁. The 10-year follow-up of the FIMPACT trial, published in the BMJ in 2025, found real surgery beat placebo surgery by about 1.5 points on a 100-point pain scale. You need around 15 points to even notice a difference. It was also no better than simple exercise therapy. 𝗩𝗲𝗿𝘁𝗲𝗯𝗿𝗼𝗽𝗹𝗮𝘀𝘁𝘆 𝗳𝗼𝗿 𝘀𝗽𝗶𝗻𝗮𝗹 𝗳𝗿𝗮𝗰𝘁𝘂𝗿𝗲𝘀. Two 2009 NEJM trials compared injecting cement into fractured vertebrae to a fake procedure — same needle, same pressure, even the smell of cement, but no injection. No meaningful difference. Both groups improved fast. Why does this happen? Because for subjective outcomes like pain, the ritual of surgery is one of the most powerful placebos in all of medicine. The anesthesia. The operating room. The care. The deep psychological closure of believing something decisive was done to fix you. That effect is often larger than any pill — and when you control for it, several high-volume operations simply collapse. Now the honest other half, because I won't overstate this. Not every surgery is placebo. Many are genuine, life-saving mechanical fixes. Even in cardiology, stents for stable angina looked no better than sham in the first ORBITA trial — but when the follow-up study controlled it more precisely, the stent clearly reduced symptoms. Real fixes can and do beat placebo. These four just didn't, for these conditions. And these trials are rare, because sham surgery is ethically and logistically hard to run. Which means there are almost certainly other common procedures we've simply never tested this way. So here is what I want you to do if you're ever offered surgery for chronic pain. Ask one question: "What did the sham-controlled trial show?" For many joint and back pain conditions, physical therapy, exercise, weight loss, and time match or beat the operation — without the infection risk, the anesthesia risk, the blood clots, the cost, and the recovery. Surgery is sometimes exactly what you need. But sometimes the most powerful treatment in the room is simply the belief that treatment has occurred. Your body has more healing power than the system profits from admitting.
