Arthrosamid Injections

Arthrosamid® is a cutting-edge permanent injectable hydrogel that delivers long-lasting, proven pain relief for knee Osteoarthritis – improving your quality of life without surgery.

How Does It Work?

The first and only approved injectable treatment that permanently combines with the knee’s synovial tissue, Arthrosamid decreases joint stiffness, diminishes pain, improves the function of the knee, and enhances your quality of life.

Supported by more than two decades of research , Arthrosamid® is suitable, safe and effective for most patients with knee OA — and is proven to maintain a significant, long-lasting reduction in knee OA pain even five years post-treatment.

The Benefits

When Arthrosamid® is positioned within the tissue lining of the knee joint, it softens and increases the elasticity of this tissue – thereby improving knee functionality and reducing pain.

It’s this unique characteristic that provides a significant reduction in your OA pain over a longer period — with one single treatment.

What should I expect immediately after treatment with Arthrosamid®

  • Following the procedure, you may be allowed to leave the clinic immediately, or you may wish to rest until you feel ready to go.
  • Your knee may start to feel uncomfortable as the anaesthetic wears off, but many patients do not report any discomfort.
  • If you do feel discomfort, symptoms may include mild to moderate pain and/or swelling at the injection site. If your knee becomes red, hot, largely swollen or more painful, you should immediately contact your Arthrosamid® physician for treatment.
  • You should continue your regular medication and pain killers as normal.
  • Please note, receiving Arthrosamid® may feel like a different sensation to other treatments that you have previously experienced as it is more viscous than other injectables.

What to Expect

Step 1:
Steps 2 & 3:
Step 4:

Your knee will be cleaned prior to treatment.

Arthrosamid® is then singularly injected into your knee’s synovial cavity. This might be performed with the help of ultrasound.

The needle is then removed and a plaster is placed over the injection site

During Treatment

Arthrosamid® is administered via a simple, one-step procedure performed by a qualified physician familiar with joint injections ensuring you’re in and out of the clinic the same day. Before treatment with Arthrosamid®, you will have a local anaesthetic to numb the area around your knee. You will also be given antibiotics ahead of this to protect you from any potential risk of infection.

Why Choose Upper Room Clinic

No therapies have been able to satisfactorily halt or delay OA progression or provide effective, long-lasting symptomatic relief for patients with knee OA. So, until now, treatments have tended to focus on pain relief and the management of symptoms through weight loss, exercise and physiotherapy, walking aids, knee braces, pain relief medication, injections, and knee surgery as a last resort.

Unlike hyaluronic acid injectables — where there is very little evidence to show that the effect is still noticeable at six months33 — Arthrosamid® provides a significant reduction in your knee OA pain over a longer period with one single treatment.

Treatment with Arthrosamid® remains safe and effective for its intended use five years after single injection. To date, thousands of patients have been treated with Arthrosamid® in more than 220 clinics across Europe, and 25+ clinics across Canada.
