Why does ultrasound guidance matter for knee injections?

Ultrasound guidance allows the clinician to visualise the knee joint in real time and guide the needle accurately into the correct space. This improves precision, can increase effectiveness, and reduces the risk of injecting surrounding structures. Ultrasound guidance is particularly helpful when there is joint swelling or anatomical variation.

Is it worth having a steroid injection for knee arthritis?

For many patients experiencing inflammatory flare-ups of knee osteoarthritis, a steroid injection can be worthwhile. When inflammation is controlled, walking often becomes easier, sleep may improve, and rehabilitation can be more effective. However, injections are not appropriate for everyone, so careful assessment is essential.

Ultrasound Guided Steroid Injections for Knee Pain in London

Q: What happens during your appointment?

Appointments typically last around 20–30 minutes and include a full clinical assessment, an ultrasound examination of the knee, discussion of diagnosis and treatment options, and the injection if appropriate and agreed. The £255 fee includes a telephone assessment prior to your visit, a full in-clinic assessment, an ultrasound scan and the injection itself. If injection therapy is not suitable, we will explain why and advise on the most appropriate management plan.

Q: Will it hurt?

A small amount of discomfort from the needle is expected, and most patients describe it as brief and manageable. Local anaesthetic can be used so the area feels numb for several hours afterwards. Once the anaesthetic wears off, the knee may feel temporarily sore before the steroid begins to take effect. This temporary flare is normal and usually settles within 24–48 hours.

Q: What should I do after the injection?

After a knee steroid injection, we recommend avoiding driving for the first few hours, resting the knee for 48 hours, and avoiding high-impact activity for two weeks. Light walking is usually acceptable. We will give tailored advice depending on your condition.

If you’re looking for a steroid injection in the knee in London, we provide ultrasound-guided treatment delivered by a senior NHS Consultant Physiotherapist with over 15 years of advanced musculoskeletal experience.

In many cases, treatment can be carried out during the same visit following a full assessment.

Is a Knee Steroid Injection Right for You?

Most people who contact us ask a version of the same question:

“Will a steroid injection actually help my knee pain?”

A knee steroid injection can be helpful when inflammation inside the joint is driving symptoms. This is common in:

Knee osteoarthritis flare-ups
Joint swelling (synovitis)
Pain limiting walking or stairs
Night pain caused by inflammation

However, not all knee pain is inflammatory. Some cases are more mechanical in nature, and injecting too early is not always the right decision.

Our approach is always conservative first. We only recommend steroid injections when appropriate, and when other measures such as activity modification or physiotherapy have not provided sufficient relief. Correct diagnosis comes before treatment.

The Benefits of Ultrasound Guidance

All knee injections at HomePhysio247 are performed under ultrasound guidance. This allows us to visualise the joint in real time and guide the needle accurately into the correct space.

Accurate

Places medication directly into the inflamed joint or tissue causing your pain.

Improved Safety

Helps avoid nearby nerves, blood vessels, and other sensitive structures.

Greater precision

Allows confident needle placement in deeper or complex areas.

Effective

Reduces the risk of the injection missing the intended target.

How Does a Steroid Injection Help the Knee?

A steroid injection delivers a corticosteroid medication directly into the knee joint.

The medication works locally to:

Reduce inflammation
Decrease swelling
Relieve pain
Improve mobility

Because the injection is delivered precisely into the joint, it acts mainly in the treated area rather than affecting the whole body.

Most patients notice improvement within several days. Maximum benefit is usually achieved within the first two to three weeks.

Relief can last from several weeks to several months, depending on the severity of osteoarthritis and activity levels. It is not a cure for arthritis, but it can significantly reduce inflammatory flare-ups and improve quality of life.

We always combine injection therapy with a structured exercise plan to maximise long-term results.

Local anaesthetic can be used, meaning the area feels numb for several hours afterwards. Once the anaesthetic wears off, the knee may feel temporarily sore before the steroid begins to take effect.

This temporary flare is normal and usually settles within 24–48 hours.

After a knee steroid injection, we recommend:

Are Steroid Injections Safe for Knee Pain?

When used appropriately and performed by an experienced clinician, steroid injections are generally safe.
