CORTISONE INJECTION IN KNEE
Knee pain caused by inflammation can make walking, exercising, or even resting uncomfortable. When swelling inside the joint is a major contributor to symptoms, a cortisone injection in the knee can provide targeted relief.
At Alton Pain Clinic, we offer ultrasound-guided cortisone injections designed to reduce inflammation, ease pain, and improve mobility so you can return to everyday activities with greater comfort.
What Is a Cortisone Injection in the Knee?
A cortisone injection is a type of corticosteroid injection placed directly into the knee joint or surrounding tissues. Corticosteroids are powerful anti-inflammatory medicines that calm the immune response in the treated area, helping reduce swelling and pain.
These injections are commonly used to treat painful joint conditions because they deliver medication exactly where inflammation is occurring. By targeting the source of irritation, cortisone injections can help improve joint comfort and make movement easier.
Conditions Treated with Cortisone Knee Injections
Cortisone injections in the knee may be recommended for several inflammatory joint conditions, including:
- Osteoarthritis of the knee
- Rheumatoid or inflammatory arthritis
- Synovitis (inflamed joint lining)
- Bursitis around the knee
- Tendon-related inflammation
- Persistent swelling after injury
These injections are often used when conservative treatments such as physiotherapy, rest, or medication have not provided sufficient relief.
How the Injection Works
Cortisone mimics the natural hormone cortisol, which helps control inflammation in the body. When injected into the knee joint, it works locally to decrease inflammatory activity, reducing swelling and easing pain.
This reduction in inflammation can lead to improved joint mobility, making it easier to walk, bend, and perform daily activities more comfortably.
What to Expect During Your Appointment
Your appointment begins with a detailed consultation and musculoskeletal assessment to understand your symptoms and functional limitations. Where appropriate, an ultrasound scan is used to confirm the diagnosis and guide the injection site accurately.
The injection itself is quick and usually well-tolerated. A fine needle is guided into the joint under ultrasound imaging to ensure precise placement. Most patients are able to walk out of the clinic afterwards, although you may be advised to rest the knee and avoid heavy activity for 24–48 hours.
Pain relief does not always occur immediately. It may take several days to notice improvement, with full benefits developing over one to two weeks.

Part of a Comprehensive Knee Care Plan
While cortisone injections can provide significant symptom relief, they are most effective when combined with physiotherapy, strengthening exercises, and activity modification. This integrated approach helps address the underlying cause of knee pain and supports long-term joint health.
At Alton Pain Clinic, we focus on accurate diagnosis, targeted treatment, and personalised care to help you stay active and maintain confident knee movement.
