Low-Dose Radiation Therapy Shows Promise in Managing Osteoarthritis
Osteoarthritis, the leading cause of disability among US adults, affects approximately 31 million people. While management involves physical therapy, painkillers, and surgery, a noninvasive alternative, radiation therapy, has shown promise. A recent study found that a single course of low-dose radiation therapy reduced pain and improved mobility in mild to moderate cases at 4 months.
Dr. Byoung Hyuck Kim led a randomized controlled trial, demonstrating the effectiveness of low-dose radiation therapy for knee osteoarthritis. Participants receiving 3 Gray of radiation experienced reduced pain and improved mobility compared to those who did not. However, high-quality data from clinical trials on its long-term effectiveness is limited.
For those who do not respond to initial treatment or experience symptom reemergence, a second dose of radiation therapy may be effective. This could help delay or prevent surgical interventions. Although there's a long-term cancer risk, studies have not shown an increase in cancer incidence after low-dose radiation therapy.
Osteoarthritis, a prevalent cause of disability, may find relief in low-dose radiation therapy. While more clinical trials are needed to confirm long-term benefits, early results suggest it could help manage pain and improve mobility, potentially delaying surgery. However, potential long-term risks must be considered.
