Low-dose radiation therapy improves knee pain and function in osteoarthritis patients

Low-dose radiation therapy shows promise in significantly improving knee pain and function for osteoarthritis patients. A recent study found that 70% of participants receiving low-dose radiation experienced meaningful improvement, compared to 42% in the placebo group. The treatment is thought to reduce inflammation. While not a first-line treatment in the US, low-dose radiation has been used in Europe for decades and may offer an alternative for those unsuitable for medication or surgery.
