Low-Dose Radiation for Osteoarthritis

What is low-dose radiation therapy?

Low‑dose radiation therapy is a medical treatment that delivers small, targeted amounts of radiation to an affected joint. Radiation therapy for osteoarthritis uses carefully controlled, very low doses of radiation, much lower than what’s used to treat cancer.

For people with osteoarthritis, inflammation inside the joint can worsen stiffness, swelling and pain. Low‑dose radiation for osteoarthritis helps calm inflammation in the joint, which may reduce pain over time. Treatments are carefully planned to focus on the painful area while minimizing exposure to surrounding healthy tissue. This therapy does not involve surgery, injections or anesthesia, and each session typically lasts only a few minutes.

Benefits of Radiation Therapy for Osteoarthritis Pain

For some patients, low‑dose radiation therapy may help:

• Reduce inflammation inside the joint
• Ease ongoing osteoarthritis pain
• Improve comfort during daily activities
• Provide a nonsurgical option when other treatments have not helped

Radiation therapy for osteoarthritis may be considered when medications, physical therapy or injections have not provided enough relief. OSF HealthCare offers many options for joint pain relief, depending on what’s causing your pain and how severe it is.

Risks and Side Effects of Low-Dose Radiation for Osteoarthritis 

Low‑dose radiation therapy is generally well tolerated, but like any medical treatment, it does carry some risks.

Possible side effects are usually mild and may include:

• Temporary skin irritation near the treatment area
• Mild fatigue

Your care team carefully weighs the potential benefits and risks before recommending this treatment. Because radiation exposure adds up over time, OSF HealthCare follows strict guidelines to ensure doses are kept as low as possible while still being effective.

Who Qualifies for Low-Dose Radiation for Osteoarthritis

Low‑dose radiation therapy may be an option for people who:

• Have diagnosed osteoarthritis in a specific joint
• Continue to experience pain despite other treatments
• Are not candidates for surgery or prefer nonsurgical care
• Have been evaluated and referred by a qualified provider

A consultation is required to determine whether this treatment is appropriate for your individual situation.
