What is Low Dose Radiation Therapy (LDRT)?

Low Dose Radiation Therapy is a gentle, non-invasive treatment designed to relieve pain and inflammation in joints affected by osteoarthritis, especially for those who have not responded to conventional therapies. LDRT uses a small amount of radiation—just enough to calm inflammation and improve mobility—with virtually no side effects.

How Does It Work?

LDRT is changing the way we treat osteoarthritis—gently, safely, and effectively.
  • Targeted Treatment

    LDRT targets the affected joint with a small dose of radiation that is significantly lower than what is used in cancer treatment or some diagnostic imaging.

  • Immune Modulation

    This dose helps reduce inflammation and modulate the immune response, slowing or halting the progression of osteoarthritis rather than just masking symptoms.

  • Quick Sessions

    Each session is quick—about 10 minutes total, with the actual treatment time being less than 20 seconds per joint. A full course involves 6 to 8 sessions given twice weekly over a few weeks.

Benefits of LDRT

Rapid Pain Relief

Many patients notice improvement after just one treatment, with maximum benefit after six sessions.

Long-Lasting Results

Relief can last up to two years, and treatment can be repeated if needed.

Minimal Side Effects

No/minimum skin redness, no burning, or downtime. Most patients return to normal activities immediately after each session.

Non-Invasive Alternative

For those who want to avoid or are unable to undergo  surgery or long-term medication use.

Is LDRT Right For You?

Our infusion team provides individualized treatment plans designed to minimize side effects and maximize comfort. Each session is monitored by experienced oncology nurses who explain medications, treatment timing, and follow-up care—so you always know what to expect.

Who can benefit from Low Dose Radiation Therapy (LDRT)?

LDRT is recommended for adults with osteoarthritis of the knees, hips, hands, shoulders, ankles, or elbows who have not found relief with other treatments. It is especially considered for those aged 65 and older, before more invasive procedures are explored.

Is Low Dose Radiation Therapy a safe option for osteoarthritis?

Yes. LDRT uses extremely low doses of radiation—about 3 units, compared to 40–80 units commonly used in cancer treatments—which makes the risk of side effects or secondary cancer very low. The most common limitation is that it may not provide complete relief for every patient, but approximately two-thirds of individuals experience significant improvement.

Why is LDRT a trusted choice for joint pain relief?

Low Dose Radiation Therapy is backed by over 100 years of clinical use and supported by numerous studies worldwide. It is used extensively across the globe and is now recognized in the United States as a safe, effective treatment—covered by Medicare and most major insurance plans.
