Is Knee Pain Starting To Limit Your Life?
If this sounds familiar, it may be time to explore what other treatment options are available.
What Is An Arthrosamid® Injection?
Arthrosamid® is a non-surgical hydrogel injection for adults with knee osteoarthritis.
It contains 2.5% cross-linked polyacrylamide and 97.5% water. Once injected into the knee joint, the hydrogel integrates with the synovial tissue lining the joint, helping to change its mechanical properties.
The aim is to reduce osteoarthritis-related pain and improve knee function.
At a Glance:
Designed for knee osteoarthritis
Specifically intended for the symptomatic treatment of knee osteoarthritis.
Long-term potential
Studies have reported sustained improvement in some patients, although individual results vary.
One injection procedure
A single 6 ml dose is injected into the affected knee.
Non-surgical
Treatment is carried out as an outpatient procedure.
How Does Arthrosamid® Work?
Injection therapy may be considered for a range of joint, tendon, and nerve-related conditions where pain, stiffness, or inflammation is limiting movement or recovery.

Injected Into The Knee
The hydrogel is placed into the affected knee joint.

Why Consider Arthrosamid®?
For suitable patients, Arthrosamid® may offer:
A Non-Surgical Option
No joint replacement surgery is involved.
A Single Treatment Procedure
One 6 ml injection rather than a scheduled series.
A Different Approach
It works differently from steroid and hyaluronic acid injection.
Longer-Term Potential
Research has reported sustained improvements in pain and function for some patients.
Results vary, and no treatment can guarantee a particular outcome.
Could Arthrosamid® Be Right For You?
Arthrosamid® may be worth discussing if:
- You have knee osteoarthritis
- Pain or stiffness is limiting everyday movement
- Walking, stairs or exercise are becoming more difficult
- Conservative treatment has not provided enough relief
- You want to explore a non-surgical option
Arthrosamid® is not suitable for everyone. Your diagnosis, symptoms, medical history and previous treatment should all be considered before treatment is recommended.
Not sure? That is what the assessment is for.
Booking an assessment does not mean committing to an injection.

What If Arthrosamid® Is Not Right For Me?

FAQs
Each knee requires individual assessment. Your clinician can advise whether treatment is appropriate and how it should be planned.
Your clinician will assess your knee clinically. Imaging such as an X-ray or scan may be requested if it would help confirm your diagnosis or suitability for treatment.
Arthrosamid® may help manage symptoms and could delay the need for surgery for some patients, but this cannot be guaranteed. Your clinician will discuss what may be realistic for your individual case.
Let your clinician know about your full medical history, any allergies, current medications, previous knee treatments and any concerns you have, so they can confirm whether Arthrosamid® is appropriate for you.
