This clinical trial is a multicenter, randomized, single-blinded, exploratory clinical trial to evaluate the efficacy and safety of low-dose radiation for knee osteoarthritis patients. The experimental group is treated with low-dose irradiation 6 times for 3 weeks according to the dose determined for each group, and the control group is treated with sham irradiation. Both the experimental group and the control group visit the hospital 4 weeks after irradiation and at 4, 8, and 12 months to evaluate the efficacy and safety.
Clinical verification of knee osteoarthritis pain relief and functional improvement using low-dose radiation therapy
