ULTRASOUND GUIDED INJECTION
What is an Ultrasound Guided Injection?
An ultrasound-guided injection is a procedure in which a musculoskeletal ultrasound machine is used in real time to guide a needle precisely to the intended target — whether that is a joint, bursa, tendon sheath, or specific soft tissue structure.
The clinician watches the needle on the ultrasound screen as it is inserted, allowing them to confirm that the tip of the needle is exactly where it needs to be before the medication is administered. This is in contrast to a landmark-guided (or “blind”) injection, where the needle is inserted based on external anatomical landmarks without direct visualisation.
Why does Guidance Matter?
Accuracy is fundamental to the success of any injection therapy. Studies comparing ultrasound-guided injections with landmark-guided injections consistently show that guided injections are significantly more accurate — with accuracy rates of 85–98% for guided injections compared to as low as 50–70% for blind injections, depending on the joint.
When an injection misses its target:
- The medication does not reach the intended structure and therapeutic benefit is reduced
- There is a risk of depositing the medication into unintended structures — such as fat tissue, subcutaneous tissue, or directly into a tendon
- In the case of repeated misplaced injections, there is greater risk of local tissue damage
Ultrasound guidance eliminates these risks by providing real-time visual confirmation of needle placement.
What can be seen on Ultrasound?
Musculoskeletal ultrasound provides excellent visualisation of:
- Joints — including the hip, knee, shoulder, ankle, and wrist
- Tendons — showing normal and abnormal tendon tissue, tears, and calcification
- Bursae — fluid-filled sacs that can become inflamed
- Ligaments — useful for assessing sprains and partial tears
- Nerves — for nerve blocks and perineural injections
- Soft tissue masses — such as ganglion cysts and Baker’s cysts
Ultrasound also allows dynamic assessment — the clinician can observe the structure as it moves, which can reveal problems that are not apparent on static imaging.
What types of injection are guided by Ultrasound at Alton Pain Clinic?
At Alton Pain Clinic, ultrasound guidance is used as standard for all injection procedures, including:
- Cortisone (corticosteroid) injections into joints, bursae, and tendon sheaths
- Hyaluronic acid injections (viscosupplementation)
- Cingal injections (combined HA and steroid)
- PRP (platelet-rich plasma) injections into tendons, joints, and ligaments
- Arthrosamid injections for knee osteoarthritis
- Aspiration procedures for cysts, bursae, and joint effusions

Is Ultrasound Guidance Safe?
Yes. Ultrasound uses high-frequency sound waves to create images — there is no radiation involved, making it entirely safe for repeated use. It is the same technology used to image babies during pregnancy and to assess soft tissues throughout medicine.
The procedure itself is minimally invasive. A small probe is placed on the skin over the area to be injected, and the needle is inserted through the skin under real-time guidance.
What to expect at your injection appointment at Alton Pain Clinic
- A consultation with our clinician to review your symptoms, medical history, and any existing imaging
- Ultrasound assessment of the affected area — this takes five to ten minutes and gives the consultant a real-time picture of the target structure
- The skin is cleaned and, where appropriate, local anaesthetic applied
- The ultrasound probe is positioned and the injection performed under continuous imaging — the procedure typically takes two to five minutes
- Post-procedure advice on activity, expected response, and follow-up
Most appointments last 30–45 minutes in total. You should be able to drive home after the procedure in most cases (though if sedation or a nerve block affecting leg sensation is used, this may not be the case — your clinician will advise).
Why Alton Pain Clinic uses ultrasound guidance for every injection
Ultrasound guidance is not universally offered by all injection clinics. Some practitioners still perform blind injections based on anatomical landmarks alone, particularly for commonly injected joints such as the shoulder and knee.
At Alton Pain Clinic, we believe that every patient deserves the most accurate injection possible. Real-time guidance improves outcomes, reduces discomfort, and minimises the risk of complications — regardless of which joint or structure is being injected. It is a fundamental part of how we practise.
Frequently Asked Questions
Do ultrasound-guided injections hurt more than blind injections?
No — in most cases, the opposite is true. Because the needle is placed precisely, the procedure is often quicker and involves less probing for the target structure, which reduces discomfort. For sensitive areas, local anaesthetic can be applied to the skin beforehand.
How is ultrasound guidance different from X-ray guidance (fluoroscopy)?
Ultrasound uses sound waves and involves no radiation; fluoroscopy uses X-rays. Ultrasound is better for soft tissue injections (tendons, bursae, ligaments, joints near the surface). Fluoroscopy or CT guidance is used for deeper spinal injections where soft tissue visualisation is less critical and bony landmarks are more important.
Will I need to do anything to prepare for an ultrasound-guided injection?
In most cases, no specific preparation is required. Wear comfortable, loose-fitting clothing that allows easy access to the area being treated. Let us know in advance if you are taking blood-thinning medication, as this may affect our approach.
