Low-dose radiation therapy offers substantial relief to people with painful knee osteoarthritis

A single course of low-dose radiation therapy may provide a safe and effective alternative treatment option for people with painful knee osteoarthritis according to a new randomized, placebo-controlled clinical trial.

The study showed patients with mild to moderate knee osteoarthritis reported significant reductions in pain and improved physical function in the four months after receiving the low dose of radiation, which was just a small fraction of what's used to treat cancer. The study included a control group with simulated treatment.

Low-dose radiation is regularly used for joint pain in European countries such as Germany and Spain.

The doses were less than 5% of those typically used for cancer treatments, and no radiation-related side effects were observed.

In this multicenter trial, researchers enrolled 114 patients with moderate-to-mild knee osteoarthritis across three academic centers in Korea. Participants were randomly assigned to receive one of two radiation regimens—a very low dose (0.3 Gy) or a low dose (3 Gy)—or a control group that underwent simulated (sham) radiation. In this placebo group, patients went through the same setup for radiation therapy, but the treatment machine did not deliver any radiation. All participants received six sessions and did not know which group they were in.

After four months, 70% of patients in the 3 Gy group met responder criteria, compared to 42% in the placebo group (p=0.014). Outcomes in the 0.3 Gy group were not significantly different from the control group (58.3% improved, p=0.157), indicating the 3 Gy regimen drove relief beyond placebo effects.

Meaningful improvements in the composite score of pain, stiffness and physical function were reported more often in the 3 Gy group (56.8%) than in the placebo group (30.6%, p=0.024). For other secondary outcomes, including the amount of pain medication needed, there were no significant differences.

Thank you very much and God bless you.

A simple treatment with low dose radiation helped mild to moderate osteoarthritis patients.

I believe they are saying that the pain relieving effects last for about four months.
Probably better than using cortisone for joint pain, something I used to have done for my ankles.

But if they get angry, their skin turns green and they start developing large musculature everywhere on their body, and then . . .

I’ve had two knee surgeries. Ibuprofen and a Grey Goose Martini also offer substantial relief.

Surgeon General recommends not consuming the ibuprofen and Martinis at the same time. Ibuprofen in the morning, when necessary, and the Grey Goose Martini in the evening, when necessary, desired, or preferred, is acceptable.

I believe the study just lasted four months.

Oh. I see. Thanks for clarifying. It would be interesting to know how long any such relief did last.

Just finished first round of treatment. Six low dose exposures, six more starting again in November.

Pain level in knee substantially reduced. From a 6-7 level down to a 2-3.

So what’s the hypothesis on how/why this may work? Does the radiation provoke an anti-inflammatory response?
