Corticosteroid Injection Knee: Long-Lasting Relief for Chronic Knee Pain Without Surgery

Knee pain can disrupt even the most basic aspects of life—from walking to climbing stairs, or simply getting out of bed. For those dealing with chronic knee conditions such as osteoarthritis, rheumatoid arthritis, or tendon inflammation, a corticosteroid injection in the knee can offer swift, effective relief.

In this in-depth blog, we’ll cover everything you need to know about corticosteroid injections for the knee: how they work, who can benefit, what to expect, and why Physios R Us is a trusted provider of this treatment in the UK.

What Is a Corticosteroid Injection?

Corticosteroids are synthetic versions of hormones naturally produced by your adrenal glands. These powerful anti-inflammatory medications can be injected directly into a joint to quickly reduce pain, swelling, and stiffness.

When used in the knee, the goal is to relieve inflammation within the joint capsule, often caused by wear-and-tear (osteoarthritis), injury, or autoimmune conditions.

Conditions That Benefit from Knee Corticosteroid Injections

A corticosteroid injection in the knee is often used to treat:

• Osteoarthritis
• Rheumatoid arthritis
• Gout and pseudogout
• Meniscal tears (if inflammation is involved)
• Post-traumatic joint inflammation
• Chronic synovitis (inflammation of joint lining)

This treatment is most suitable when pain is persistent, localised, and resistant to oral medications or physiotherapy alone.

Benefits of Corticosteroid Injections in the Knee

Patients who receive corticosteroid injections often report the following benefits:

• Rapid reduction in pain and swelling
• Improved range of motion
• Better quality of sleep and mobility
• Avoidance or postponement of surgery
• Complementary support to ongoing physiotherapy

For many, the injection provides relief lasting several weeks or even months.

What to Expect During the Procedure

At a reputable clinic like Physios R Us, the procedure is safe, fast, and minimally invasive. Here’s what you can expect:

Step-by-step:

• Assessment – A clinician will review your condition and medical history.
• Imaging (if required) – Ultrasound or MRI may be used to confirm the diagnosis.
• Preparation – The knee is sterilised and numbed with a local anaesthetic.
• Injection – The corticosteroid is injected into the joint space, often under ultrasound guidance for accuracy.
• Aftercare – You’ll receive instructions and may rest briefly before going home.

The entire procedure typically takes under 30 minutes.

Recovery and Aftercare

Most people can resume light activity within a day, though rest is recommended for 24–48 hours to maximise the effects.

Aftercare tips:

• Avoid strenuous activity for 48 hours
• Apply ice if there is localised soreness
• Monitor for signs of infection (redness, swelling, fever – rare)
• Attend follow-up physiotherapy to strengthen the knee

Pain relief often begins within 1 to 3 days, with maximum results in 1 week.

How Long Do Results Last?

The relief provided by a corticosteroid injection varies depending on the individual and underlying condition. For osteoarthritis, results typically last between 6 weeks to 6 months.

Repeat injections may be spaced out every few months if needed, but most clinicians recommend no more than 3 to 4 injections per year to avoid potential joint damage.

Are There Any Risks?

Corticosteroid injections are considered low-risk, especially when performed by experienced clinicians. Possible (but uncommon) risks include:

• Infection at the injection site
• Temporary flare-up of joint pain ("post-injection flare")
• Skin discolouration or fat thinning near the injection
• Tendon weakening or rupture (rare)
• Joint cartilage damage with excessive use

Your provider at Physios R Us will thoroughly discuss these with you before the procedure.
