Quiet Hip Arthritis Pain When Surgery Has to Wait

Is radiofrequency ablation an option for hip arthritis pain?

Hip radiofrequency ablation (RFA) uses heat to quiet the small sensory nerves that carry pain from the front of the hip joint, mainly branches of the femoral and obturator nerves. It is an option for arthritis pain when surgery is not a good fit or must wait. Relief often lasts 6 to 12 months, and the joint itself is unchanged.

Some people with painful hip arthritis are not ready for a replacement, or have health issues that make major surgery risky. Hip radiofrequency ablation treats the pain signal instead of the joint. It starts with a test block, so you know whether it is likely to help before committing to the procedure.

Is this right for you?

Usually a good fit if

  • Hip arthritis pain in people whose health makes surgery high risk
  • Patients who want to delay a hip replacement for personal or work reasons
  • People whose cortisone shots no longer last
  • Some patients with ongoing pain after a hip replacement once other causes are ruled out

Another option may be better if

  • Younger active adults with labral tears or FAI, where the structural problem needs a different solution
  • Pain mainly from the outside of the hip, the buttock or the lower back
  • Anyone with infection at the site or who does not get relief from the test block

What happens, step by step

  1. A test nerve block

    A small amount of numbing medicine is placed next to the sensory branches of the femoral and obturator nerves under X-ray or ultrasound guidance. If your usual hip pain drops by at least half for the next several hours, you are a candidate for ablation.

  2. Preparing for ablation

    On a separate day, you lie on your back and may receive light sedation. The skin is numbed over the front of the hip.

  3. Heating the nerves

    Thin probes are positioned under live X-ray (fluoroscopy) near the target nerves. A test current confirms safe placement away from the motor nerves, and each site is then heated for about 90 seconds.

  4. Heading home

    The procedure usually takes 45 to 60 minutes. You need a ride home.

Typical recovery timeline

Days 1 to 3

Soreness at the probe sites is common. Ice and acetaminophen usually help.

Week 1

Some people notice a mild sunburn-like or numb feeling on the front of the thigh, which usually fades.

Weeks 2 to 4

Pain relief builds as the treated nerves stop sending signals. Walking and therapy are encouraged.

Months 6 to 12

Many people who respond keep meaningful relief for about 6 to 12 months.

When pain returns

Nerves can regrow, and the procedure can often be repeated. Dr. Stride reviews whether repeat RFA or a replacement makes more sense.

Timelines are typical ranges. Your plan depends on your hip, your health and what was done in surgery.

“A new hip is still the most reliable fix for worn-out arthritis. For some of my patients, though, surgery is not safe or simply has to wait, and they deserve relief in the meantime. Ablation does not change the joint, and I make sure you understand that before we start.”

Dr. Stride, MD

Frequently asked questions

How long does hip radiofrequency ablation last?

In people who respond, relief commonly lasts about 6 to 12 months. Some people get longer relief and some get less. The treated nerves slowly regenerate, and the procedure can usually be repeated.

Is hip RFA as good as a hip replacement?

No. A hip replacement removes the worn joint surfaces and is the most reliable long-term treatment for advanced arthritis. RFA only reduces the pain signal and suits people who cannot or prefer not to have surgery right now.

What are the risks of hip nerve ablation?

Most side effects are minor, such as soreness, bruising or temporary numbness on the front of the thigh. Rarely, thigh muscle weakness can occur if a motor nerve is affected. Careful placement under X-ray with test stimulation helps lower that risk.

Does insurance cover hip radiofrequency ablation?

Coverage for hip RFA varies by plan and is less consistent than for spine or knee ablation. Our team checks your benefits and gets any required approval before scheduling. You will know the expected cost in advance.
