Musculoskeletal ultrasound — often called MSK ultrasound — has become one of the most practical tools in physiotherapy and sports medicine. It's quick, uses no radiation, and produces real-time images that can guide both diagnosis and treatment. Ultrasound-guided injections take that a step further, using live imaging to place a therapeutic substance precisely where it needs to go.
What is MSK ultrasound?
MSK ultrasound uses high-frequency sound waves to image the soft tissues around joints: tendons, muscles, ligaments, bursae and the structures immediately surrounding them. Unlike MRI, it produces moving images in real time as the physiotherapist or clinician assesses the area.
It's particularly useful for:
- Tendon injuries (rotator cuff, Achilles, patella, elbow tendons)
- Soft tissue masses or swellings that need characterising
- Bursitis — inflammation of the fluid-filled cushioning sacs around joints
- Dynamic assessment — watching how a tendon or muscle behaves during movement
What are ultrasound-guided injections?
When an injection is indicated, placing it blind — relying on anatomical landmarks alone — carries a meaningful miss rate for some targets. Ultrasound guidance changes that. The clinician watches the needle on screen in real time, directing it precisely to the target site before releasing any substance.
This matters because:
- Accuracy reduces the risk of affecting surrounding structures
- A well-placed injection is more likely to produce the desired therapeutic effect
- Some targets, such as deep bursae and small joints, are genuinely difficult to reach without imaging guidance
At Northwest Health, ultrasound-guided injections are available from £200.
What happens during the procedure?
The appointment is straightforward:
- Your physiotherapist will take a clinical history and examine the area first
- Diagnostic ultrasound images are taken to assess the affected structure
- If an injection is appropriate, the skin is cleaned and a fine needle is guided under live ultrasound to the target
- The procedure typically takes 20–30 minutes in total
- You'll receive aftercare advice and a plan for any follow-up physiotherapy
Most people experience little more than mild discomfort during the needle placement. You'll normally be advised to rest the area for 24–48 hours afterwards.
Is a referral needed?
No. You can self-refer directly to our physiotherapy team. An initial physiotherapy assessment costs from £80 and includes a full clinical evaluation. If ultrasound assessment or a guided injection is appropriate, your physiotherapist will discuss this with you at that appointment.
Who is it suitable for?
MSK ultrasound and guided injections are used across a wide range of conditions, including:
- Shoulder impingement and rotator cuff problems
- Tennis elbow and golfer's elbow
- Hip bursitis
- Plantar fasciitis
- Achilles tendinopathy
- Knee and ankle joint conditions
They're not appropriate for everyone, and your physiotherapist will be straightforward with you about whether an injection is likely to be helpful in your specific situation. Injections are one part of a broader plan — not a standalone fix.
