If you’ve found yourself Googling “knee pain treatment without surgery” or “can you still play golf with osteoarthritis,” you’re in good company. Tens of millions of Americans are living with joint pain from osteoarthritis — and a significant portion of them are still trying to stay active, still trying to play the sports they love, and still trying to find something that actually works.

Most have tried the usual path: anti-inflammatory medications, cortisone injections, physical therapy. Some get temporary relief. Most are eventually told their only real option is joint replacement surgery.

But there’s a treatment option most people have never heard of — one that’s been used in European medicine for over a century and is only now becoming available at select U.S. centers. It’s called Low-Dose Radiation Therapy, or LDRT. And for the right patients, it’s changing the conversation.

What is LDRT, and how does it work?

LDRT uses very low doses of precisely targeted radiation — about 1/100th of what’s used in cancer treatment — to calm the inflammatory process happening inside an arthritic joint. Rather than masking pain, LDRT addresses the underlying biology: it suppresses the pro-inflammatory cytokines responsible for the ongoing pain cycle in osteoarthritis.

The treatment involves 6 short outpatient sessions, each lasting under 10 minutes. Most patients complete their full course in 2–3 weeks. There’s no surgery, no anesthesia, no hospital stay, and no recovery period.

Published clinical studies report a 65–90% pain response rate across knee, hip, shoulder, hand, and foot OA — with relief typically lasting 1–3 years.

Who’s a good fit? The active adult who’s tried everything else.

LDRT isn’t for everyone — but it’s a strong option for adults 45 and older with confirmed osteoarthritis who haven’t found lasting relief from conventional treatments.

It’s particularly relevant for people who are still active — or want to be. The patients who tend to respond best are those who aren’t ready to stop doing what they love, but whose joints are making it harder every year. Runners dealing with knee OA. Golfers with hip or hand pain. Pickleball players whose shoulder or knee keeps flaring after a match. Learn more about LDRT treatment for sports injuries.

Ideal candidates have typically tried and found limited relief from NSAIDs or steroid injections, prefer to avoid surgery, and are looking for a non-systemic treatment option with minimal side effects.

Why haven’t I heard of this?

That’s one of the most common questions patients ask. LDRT has been standard practice in Germany and parts of Europe for decades — but the U.S. medical system was slower to adopt it. Only recently have American radiation oncologists begun offering it for benign musculoskeletal conditions, and only a small number of centers have the equipment, expertise, and clinical protocols to do it properly.

At Capital Radiosurgery Centers, LDRT for osteoarthritis and joint pain is offered under the direction of Dr. Robert Hong, MD — one of a select group of U.S. radiation oncologists trained specifically in this treatment for benign conditions.

What does treatment actually look like?

The process starts with a consultation to confirm candidacy and review imaging. If LDRT is a good fit, a brief CT simulation maps the joint for precise planning. Then comes the treatment itself: 6 sessions of 0.5 Gy each, delivered 2–3 times per week over 2–3 weeks.

Patients typically begin noticing pain relief within 4–6 weeks of completing treatment. For those who don’t achieve full relief, a second course is available at the 3-month follow-up.

LDRT is covered by Medicare and most major insurers.

Still active, still hurting? There may be another option.

If you’ve been managing joint pain for years and wondering whether this is just something you have to accept — LDRT may be worth a conversation. A consultation at CRC takes about 30 minutes. Our team will review your history and imaging and give you an honest assessment of whether LDRT is right for you. Schedule a consultation today.
