Knee injections are increasingly used as part of the management of persistent knee pain and conditions such as osteoarthritis. Depending on the individual, injections may include corticosteroids, hyaluronic acid or combination products such as Cingal.
But choosing the right injection is only part of the process.

Where and how the injection is delivered matters too.
At PhysioImpulse in Bath, we use ultrasound guidance for our knee joint injections. This allows us to see the relevant anatomy in real time and guide the needle precisely towards the intended target.

What is an ultrasound-guided knee injection?
An ultrasound-guided injection uses diagnostic ultrasound to visualise the knee before and during the procedure.
The ultrasound allows us to identify the joint and surrounding structures and then guide the needle towards the intended injection site. The needle can be seen on the ultrasound screen as it is carefully advanced into position.
This provides a level of visual precision that isn't possible when relying solely on external anatomical landmarks.
Rather than estimating the position of the joint, we can see the target and guide the needle towards it.

Why does accuracy matter?
A knee injection is intended to deliver the treatment to a specific anatomical location.
For an intra-articular knee injection, the aim is to place the needle accurately within the knee joint. Ultrasound guidance allows the clinician to visualise the joint and needle throughout the procedure, helping ensure that the treatment is delivered to the intended area.
Research supports the increased accuracy of ultrasound-guided knee injections. A 2026 systematic review of 13 studies found an overall accuracy of 95.4% for ultrasound-guided knee injections and aspirations, compared with 82.0% using landmark guidance.
For us, this is one of the major advantages of ultrasound guidance: precision.
Seeing the knee rather than estimating the targetOne of the biggest benefits of ultrasound guidance is the ability to visualise the anatomy throughout the procedure.
It allows the clinician to:

• Identify the relevant anatomy before the injection
• Select the most appropriate injection approach
• Visualise the needle as it is introduced
• Guide the needle towards the intended target
• Confirm needle position before delivering the injection
• Identify and avoid important surrounding structures where appropriate

This can be particularly useful when the anatomy is altered by osteoarthritis, previous surgery, swelling or joint effusion.

Common knee injections
There isn't one injection that is suitable for every patient. The choice depends on your symptoms, diagnosis, clinical findings and individual circumstances.

Corticosteroid injections
​Corticosteroid injections are commonly used to help reduce pain and inflammation within the knee and can provide useful short-term symptom relief for appropriate patients.

Hyaluronic acid injections
Hyaluronic acid injections, including products such as Ostenil Plus, may be considered for people with symptomatic knee osteoarthritis. They are designed to supplement the joint's natural synovial fluid and can help reduce pain and improve function in suitable patients.

Cingal injections
Cingal combines hyaluronic acid with a corticosteroid in a single injection. It can be considered for appropriate patients with symptomatic knee osteoarthritis where both components of the treatment may be beneficial.

The most appropriate injection will depend on your individual circumstances and will be discussed as part of your assessment.

​Ultrasound-guided knee injections in Bath

At PhysioImpulse, we combine detailed clinical assessment with ultrasound technology to provide accurate, targeted injection treatment.

Our aim is simple: to identify the right treatment for the right patient and deliver it as precisely as possible.

If you have persistent knee pain, knee osteoarthritis or have been considering an injection, an assessment can help determine whether an injection is appropriate and which option may be best suited to you.

Shoulder pain is one of the most common reasons people seek treatment, and often the first thing they hear is, “You’ve got a rotator cuff tear.” While that can sound alarming, the reality is far more reassuring.

What is the rotator cuff?
The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint. Together they help lift your arm, rotate your shoulder and, most importantly, keep the ball of the shoulder centred in its socket during movement.
Like many parts of the body, these tendons naturally change as we get older.

Are rotator cuff tears common?
Yes – incredibly common.
Research has consistently shown that many people have rotator cuff tears without experiencing any pain whatsoever. In fact, the likelihood of having a tear roughly mirrors your age:

• Around 50% of people in their 50s have a rotator cuff tear.
• Around 60% of people in their 60s have a tear.
• Around 70% of people in their 70s have a tear.

Many of these people have no shoulder pain and don’t even know the tear exists.
This is an important point because finding a tear on an MRI or ultrasound does not automatically mean it is the cause of your pain, nor does it mean you need surgery.

What’s the best treatment?
​For the vast majority of rotator cuff problems, the gold standard treatment is a graded strengthening programme.
A physiotherapist will assess your shoulder, identify which movements and muscles need improving, and create an exercise programme that gradually reloads the tendon. This isn’t about generic exercises from the internet—it’s about progressively building strength, improving shoulder mechanics and helping the tendon tolerate load again.
Just like muscles become stronger with exercise, tendons respond positively to carefully prescribed loading over time.
The right exercises can:

• Reduce pain
• Improve strength
• Restore movement
• Help you return to work, sport and everyday activities
• Reduce the likelihood of ongoing problems

What about injections?
Injections can be an excellent option for some patients.
When pain is preventing you from sleeping, working or participating in rehabilitation, a corticosteroid injection can reduce inflammation and settle pain. This often creates a valuable window of opportunity to begin or progress your strengthening programme.
However, it’s important to understand that an injection does not heal the tendon.
The tendon becomes stronger through progressive loading and rehabilitation. Think of an injection as helping to calm things down, while exercise addresses the underlying problem.
The best outcomes are often achieved when injections are combined with a structured rehabilitation programme rather than used in isolation.

Does everyone need surgery?
No. Although surgery has an important role for some people, it is not a quick fix.
Recovery following rotator cuff surgery can take many months and still requires a comprehensive physiotherapy rehabilitation programme afterwards.
Current evidence suggests that many patients improve significantly with high-quality physiotherapy alone, meaning surgery may never be required.
Surgery is usually considered when:

• Symptoms remain significant despite a good course of physiotherapy.
• There has been an acute traumatic tear in the right circumstances.
• There is substantial weakness or loss of function.
• Imaging findings and clinical symptoms clearly match.

When surgery is appropriate, it should be part of a carefully considered treatment plan rather than the first option.

How can we help?
At Physioimpulse, we offer the full range of evidence-based treatments for rotator cuff pain, including:
✔ Comprehensive physiotherapy assessment
✔ Individualised strengthening and rehabilitation programmes
✔ Hands-on manual therapy where appropriate
✔ Ultrasound-guided injections to help control pain and facilitate rehabilitation
✔ Shockwave therapy for selected tendon conditions

Most importantly, we work closely with experienced local shoulder surgeons. If your assessment suggests surgery may be beneficial, we’ll ensure you’re referred to the right specialist at the right time. Equally, many patients can avoid surgery altogether through expert rehabilitation.
If you’re struggling with shoulder pain, don’t panic if you’ve been told you have a rotator cuff tear. The scan is only one piece of the puzzle, and with the right treatment, many people make an excellent recovery without an operation.

If you’d like an assessment or would like to discuss the best treatment options for your shoulder, we’d be happy to help.
