Radiant Joint Alliance is a registered nonprofit organization dedicated to improving access to reliable information and community outreach about low-dose radiation therapy (LDRT) for osteoarthritis and degenerative joint conditions.
LDRT is available at a growing number of hospitals and radiation oncology practices across the United States. Major health systems, including MD Anderson, Penn Medicine, and Cleveland Clinic, now offer it for selected patients with osteoarthritis. It's been used in parts of Europe for decades.
Despite that, most patients, caregivers, and even many doctors have never heard of it. Joint pain is usually managed by primary care, orthopedics, or rheumatology, while radiation is delivered by an entirely different specialty. Those two worlds rarely talk to each other, and that gap is exactly what this site exists to close.
We built a plain-language explanation of what LDRT is, what the evidence actually shows, and a directory of hospitals and practices that offer it, so patients can walk into their next appointment with a real question to ask.
