へええええ。
膝の関節炎の治療には、関節鏡を使った手術か、針をさして、膝内部の洗浄をするかで、しないより、効果があったといわれていたが、実際にはそうした過程を経ずに、手術をした傷跡だけ残したところ、偽手術でも、同程度の効果があった、と。

At the turn of this century, arthroscopic surgery for osteoarthritis of the knee was common. Basically, surgeons would clean out the knee using arthroscopic devices. Another common procedure was lavage, in which a needle would inject saline into the knee to irrigate it. The thought was that these procedures would remove fragments of cartilage and calcium phosphate crystals that were causing inflammation. A number of studies had shown that people who had these procedures improved more than people who did not.
The results were stunning. Those who had the actual procedures did no better than those who had the sham surgery. They all improved the same amount. The results were all in people’s heads.
