Euflexxa® Knee Injections

At Lakes Radiology Morisset, we provide CT-guided Euflexxa® knee injections to help relieve pain caused by osteoarthritis.

Euflexxa contains a purified form of hyaluronic acid — a substance naturally found in healthy joints. It helps improve lubrication and cushioning within the knee, allowing smoother and more comfortable movement.

Treatment is given as a course of three injections, usually two weeks apart. Many of our Morisset and Lake Macquarie patients experience meaningful improvement after completing the full course, particularly when pain medication or physiotherapy has not provided enough relief.

This non-surgical treatment may provide symptom relief for up to six months.

FAQs

Yes. All Euflexxa injections require an appointment. Please contact us by phone or submit your referral to arrange the next available booking.

Euflexxa® is a sterile, gel-like product containing purified hyaluronan (sodium hyaluronate). Hyaluronan occurs naturally in joint fluid and acts as both a lubricant and shock absorber.

In osteoarthritis, cartilage wears down and natural hyaluronan levels decrease. Euflexxa helps supplement this loss, supporting smoother joint movement and reducing pain.

  • Pain relief for knee osteoarthritis
  • Improved mobility and function
  • Non-surgical treatment option
  • May provide relief for up to 6 months following a full course

Preparation instructions will be provided when booking. In general, you may be asked to:

  • Wear comfortable, loose-fitting clothing
  • Bring any recent imaging or reports
  • Arrange transport home if advised

Please inform our team if you are taking blood-thinning medication or have any medical conditions that may affect your treatment.

Euflexxa treatment is delivered over three sessions, typically spaced two weeks apart.

At each appointment:

  • CT imaging is used to accurately guide the injection
  • The procedure is performed in a sterile clinical environment
  • The injection is completed quickly, with minimal discomfort

You may feel a brief sting from the local anaesthetic or mild pressure during the injection. Most patients return to normal activities shortly afterwards.

After your procedure, a report will be sent to your referring doctor.

  • Duration of relief: Euflexxa may provide symptom relief for up to 6 months, whereas steroid injections often provide shorter-term relief.
  • Joint health: Euflexxa supplements natural joint fluid. Repeated steroid use may contribute to cartilage weakening over time.

Most patients experience only mild discomfort. A local anaesthetic is used, and the procedure is performed under CT guidance to ensure accuracy and comfort.

Appointments are usually brief, and you can generally return home shortly after the procedure.

Euflexxa may not be suitable if you:

  • Have had a previous allergic reaction to hyaluronan products
  • Have a joint infection or infection near the injection site
  • Are pregnant (as it has not been tested in pregnancy)

Please discuss your medical history with your doctor prior to treatment.

Euflexxa injections are bulk billed with a valid Medicare card.

Reports are typically available within 24-48 hours.

If your referral is marked urgent, please notify our team so we can prioritise your case.
