If you or a loved one suffers from knee pain due to arthritis, you know how debilitating it can be. It often seems like the only choice is to either endure it and take painkillers or undergo a complex surgery. But scientists in South Korea have recently proposed a third option. The work was presented at the annual meeting of the American Society for Radiation Oncology (ASTRO).
They found that very low doses of radiation, similar to X-rays, can significantly reduce pain and restore ease of movement. To prove this, scientists conducted a very honest experiment. Some patients were given the real procedure, and others were given a simulated one, and neither the doctors nor the patients themselves knew who was receiving the real treatment. This “blind” method ensures that the results are as true as possible.
How did it work?
The participants were divided into three groups. Two groups received a small dose of radiation therapy (one less, the other slightly more), and the third group received a placebo, or a “dummy”. The results were impressive: those who underwent real therapy experienced significant relief compared to those in the placebo group. Interestingly, both treatment doses worked equally well. And most importantly, everything was safe, without any serious side effects.
Why is this a real breakthrough?
You may be scared by the word “radiation,” but don't worry. The doses used here are tens of times lower than those used in cancer treatment and are completely safe for the body.
As one of the study leaders explained, this method could be the perfect “golden mean.” It would be perfect for those who are no longer helped by conventional pills or injections, but who are not yet ready for joint replacement surgery. It is a new, gentle and effective way to return to an active life without pain.
