Details about Knee Ultrasound
What is a Knee Ultrasound Scan?
A knee ultrasound scan is a diagnostic imaging test used to examine the soft tissues surrounding the knee joint, including tendons, ligaments, bursae and joint fluid. Ultrasound technology uses high-frequency sound waves to create real-time images of structures within and around the knee.
Unlike X-rays, which mainly show bone structures, ultrasound is particularly useful for evaluating soft tissue injuries and inflammation. It can help identify tendon damage, ligament irritation, fluid accumulation and other musculoskeletal abnormalities affecting the knee.
Because it is quick, safe and radiation-free, knee ultrasound is widely used to investigate knee pain, swelling and movement problems.
Why do I need a Knee Ultrasound?
A knee ultrasound may be recommended when symptoms suggest injury or inflammation affecting the knee joint or surrounding soft tissues.
You may benefit from this scan if you experience:
- Knee pain or discomfort
- Swelling around the knee joint
- Reduced range of motion
- Knee stiffness or instability
- Suspected tendon or ligament injury
- Fluid accumulation in the knee
- Sports-related knee injuries
- Recurrent knee inflammation
- Pain during walking, running or bending
- Monitoring of known knee conditions
Ultrasound helps identify the cause of symptoms and guide appropriate treatment or further investigation.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
