Low-Dose Radiation Therapy (LDRT) for Osteoarthritis: What You Should Know

 

Osteoarthritis (OA) is a common condition that causes pain and stiffness in the joints. While there is no cure for OA, various treatments can help manage symptoms and improve quality of life. One such treatment option is low-dose radiation therapy (LDRT).

​

What is LDRT?

LDRT uses low doses of radiation to treat inflammation and pain in the affected joint. The radiation targets specific cells involved in the inflammatory process, reducing their ability to produce inflammatory substances.

​

How is LDRT administered?

LDRT is administered in an outpatient setting. The procedure involves:

• Planning Session: You will lie on a table while the targeted joint is positioned precisely for radiation delivery and a CT scan is obtained calculate the radiation delivery specifically for you

• Treatment: The radiation is delivered through a machine similar to an X-ray machine, but with lower doses than used for cancer treatments. The actual treatment time is relatively short, usually lasting only a few minutes.

• Frequency: The number of LDRT sessions needed depends on the severity of your OA and your individual response to the treatment. A typical course of LDRT involves 6 sessions, administered two to three times a week.
  Exclusion criteria include rheumatoid arthritis, vascular disease, joint replacement, previous trauma to joints and/or the presence of lymphedema
   

Benefits of LDRT:

• Pain relief: Studies have shown LDRT to be effective in reducing pain and improving joint function in a majority of patients with OA.

• Improved mobility: LDRT can help improve flexibility and range of motion in the affected joint.

• Minimal side effects: LDRT is generally well-tolerated, with minimal side effects reported.

• Long-lasting effects: The pain relief and improved function experienced after LDRT can last for months or even years.
   

Potential risks and side effects:

• Skin irritation: The skin may become slightly red or irritated at the treatment site. This usually goes away on its own within a few days.

• Fatigue: Some patients may experience mild fatigue after treatment.

• Rare side effects: In very rare cases, more serious side effects such as skin burns or bone marrow suppression can occur. Cancer is very rare at the low doses used for arthritis and has not be reported in the literature.
   

Who is a candidate for LDRT? 

LDRT may be a good option for patients with OA who:

• Are over 50 years in age

• Have osteoarthritis of the knees, hips, hands, shoulders, ankles and/or elbows that has persisted longer than three months

• Have moderate to severe pain that has not responded adequately to other treatments.

• Are unable to take or tolerate other pain medications.

• Are looking for a non-invasive treatment option.

• Exclusion criteria include rheumatoid arthritis, severe vascular disease, joint replacement of the affected joint, previous trauma to affected joint and/or the presence of lymphedema
   

Important considerations:

• Insurance coverage: LDRT may not be covered by all insurance plans. We will assist you in checking with your insurance provider before starting treatment. Cash payment options are available for those without insurance coverage.

• Second opinion: It is always a good idea to discuss your other treatment options with your other doctors before starting LDRT.
