Low-Dose Radiotherapy (LDRT) for Osteoarthritis

What is low-dose radiotherapy?

LDRT is a non-invasive treatment that uses tiny, carefully controlled doses of radiation to help reduce pain, improve joint function, and help slow down joint damage over time. Unlike therapies for cancer, LDRT uses a much lower dose with minimal side effects.

It may be an option for people who haven’t found relief with physiotherapy or medication, are not suitable for surgery, are seeking a non-surgical approach, or want an alternative to long-term pain medication. Backed by international clinical research, LDRT can work alongside standard treatments to help people move more comfortably and regain quality of life.

What is Osteoarthritis?

Osteoarthritis is a condition that affects the joints, causing them to become stiff and painful. It most commonly affects the hips, knees, and small joints in the hands, but may occur anywhere in the body. It’s the most common form of arthritis, affecting tens of millions of people worldwide, more women than men.

Common Symptoms of Osteoarthritis

People with Osteoarthritis may experience:

• Continuous or worsening joint pain
• Stiffness and difficulty moving the affected joint
• Visible swelling or changes in joint shape

Symptoms often develop gradually and vary from person to person. Early on, pain may appear only during movement, but as the condition progresses, pain can remain even while resting.

What is LDRT?

LDRT is a non-invasive treatment that may help people with Osteoarthritis walk further, move more freely, and live with less pain. Unlike the higher doses of radiation used to treat cancer, LDRT uses a much lower, highly targeted dose. It is designed to complement, rather than replace, standard therapies, offering an additional treatment pathway for people who continue to have symptoms despite physiotherapy, medication, or other conservative measures.
International research and clinical experience show that LDRT may:

• Reduce pain and inflammation
• Improve joint function and mobility
• Potentially slow the progression of Osteoarthritis

LDRT has been safely used overseas for more than a decade, with minimal side effects due to its tiny dose of radiation. It may be an option for people who:

• Have not found relief with physiotherapy or medication
• Are not suitable candidates for surgery
• Prefer an alternative to long-term pain medication or surgery

“This non-invasive and well-tolerated treatment works for many patients. They are able to stand for longer and walk for extended periods of time with a significant reduction in their pain”. Dr Richard Shaffer, Clinical Oncologist.

By helping reduce pain and improve mobility, LDRT may support a more active, comfortable lifestyle and help people enjoy everyday activities again.

Who Might Benefit from LDRT?

LDRT may be considered in people aged 40+ with:

• Mild to moderate Osteoarthritis, as confirmed by x-ray,
• Moderate to severe pain despite medication, and/or physiotherapy

We’ll will meet with you, review your symptoms and scans, and help decide whether LDRT is the right option for you.
