Arthrosamid Injection

Knee osteoarthritis can make everyday movements such as walking, climbing stairs, exercising, or getting out of a chair more painful over time. For some people, painkillers, physiotherapy, steroid injections, or hyaluronic acid injections may only provide short-term relief.

At Southgate Physio, Arthrosamid injections are offered as a non-surgical treatment option for suitable patients with knee osteoarthritis who are looking to reduce pain, improve mobility, and support longer-term knee function.

About Arthrosamid Injection

Arthrosamid is a non-biodegradable injectable hydrogel containing 97.5% water and 2.5% cross-linked polyacrylamide. It works within the knee joint by integrating with the synovial tissue lining to provide cushioning and support longer-term symptom management.

The procedure is typically completed through a single ultrasound-guided injection into the knee joint. Following treatment, most patients can leave the clinic shortly afterwards and gradually return to light activities over the next few days.

Benefits of Arthrosamid Injection

Patients may benefit from:

• Long-term reduction in knee pain
• Improved joint movement and flexibility
• Reduced stiffness and discomfort
• Non-surgical treatment option
• Single injection procedure
• Support for maintaining an active lifestyle

Conditions Treated with Arthrosamid Injections

Arthrosamid may be suitable for patients experiencing:

• Knee osteoarthritis (mild to moderate)
• Persistent knee pain or stiffness
• Discomfort when walking, climbing stairs, or standing
• Reduced mobility affecting daily activities
• Limited response to previous injections
• Desire to avoid or delay knee surgery

Arthrosamid Treatment Safety

Current research suggests that Arthrosamid has a reassuring safety profile when delivered by appropriately trained clinicians.

Possible side effects may include:

• Mild swelling
• Temporary discomfort
• Injection site pain
• Short-term stiffness

As with any joint injection, there is a small risk of infection or other complications. Your clinician will discuss the risks, benefits, and suitability with you before treatment.

Arthrosamid Availability on the NHS

Currently, Arthrosamid is primarily available through private clinics in the UK.

The National Institute for Health and Care Excellence (NICE) has reviewed the available evidence and treatment pathway; however, there is currently insufficient evidence for the treatment to be routinely recommended within NHS guidance.

However, research activity is ongoing, with continued studies assessing long-term outcomes and patient benefit.

Why Choose Southgate Physio?

At Southgate Physio, Arthrosamid injections are provided as part of a personalised musculoskeletal assessment and rehabilitation programme.

A detailed evaluation helps determine whether this treatment is suitable for you, with physiotherapy support tailored around your symptoms, mobility goals and overall knee function. This approach focuses on:

• Improve knee pain

• Restore movement
• Reduce stiffness
• Improve long-term function
• Help patients stay active

Combining injection therapy with targeted rehabilitation may support better long-term outcomes than injections alone.
