Low Dose Radiotherapy for Osteoarthritis

This trial explores whether low-dose radiation therapy (LDRT) can reduce pain and improve function in people with osteoarthritis (OA), a common joint condition causing pain and stiffness. Participants will report their pain levels and mobility before and after treatment. The trial seeks individuals with OA in their hips, knees, hands, shoulders, ankles, or elbows for over three months who haven't found relief with standard treatments.

As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could lead to new treatment options for OA.

Research has shown that low-dose radiation therapy (LDRT) is generally safe for treating osteoarthritis. Studies have found that LDRT effectively reduces pain and improves joint function, with few side effects. Most people do not experience common radiation-related issues like skin redness or irritation. Reports from the U.S. and Europe confirm its safety, noting that negative effects are rare. Overall, LDRT is considered a well-tolerated option for managing arthritis pain.¹²³⁴⁵

Low Dose Radiation Therapy (LDRT) is unique for treating osteoarthritis because it uses low levels of radiation to potentially reduce inflammation and pain directly at the affected joints. Most traditional treatments for osteoarthritis, like pain relievers and physical therapy, focus on managing symptoms rather than altering the underlying joint environment. Researchers are excited about LDRT because it could offer a novel approach by targeting the inflammation at its source, potentially providing longer-lasting relief without the need for continuous medication. Additionally, LDRT has the potential to be a non-invasive option, making it an attractive alternative for patients looking to avoid surgery.

Studies have shown that low-dose radiation therapy (LDRT) effectively reduces pain and improves movement in people with osteoarthritis. In one study, 83% of patients reported a pain decrease of at least 2 points, and 70% experienced a decrease of 3 points or more. Research also indicates that both higher and lower doses of LDRT provide good pain relief for 3 to 12 months, with no major differences between them. Another study found that patients experienced significantly less pain and improved mobility after treatment. These findings suggest that LDRT could be a promising option for managing osteoarthritis symptoms. Participants in this trial will receive standard-of-care LDRT and complete assessments at baseline, 3-month, and 1-year follow-up.²⁶⁷⁸⁹
