What is Arthrosamid?

A permanent hydrogel that works with your knee

Arthrosamid® is a permanent injectable hydrogel that delivers long-lasting, proven pain relief without surgery, redefining treatment for knee OA.

The first 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 three years post-treatment.

How is Arthrosamid administered?

A simple, one-step procedure

Arthrosamid® is administered via a simple, one-step procedure performed under local anaesthesia by a qualified physician familiar with joint injections ensuring you're in and out of the clinic the same day.

Preparation

Before treatment with Arthrosamid®, you will have a local anaesthetic to numb the area around your knee. You should also be given antibiotics ahead of this to protect you from any potential risk of infection.

The injection

Your knee is cleaned prior to treatment. Arthrosamid® is then singularly injected into your knee's synovial cavity. At The Treatment Table, this is always performed under live ultrasound guidance for accuracy. The needle is then removed and a plaster is placed over the injection site.

Every injection at The Treatment Table is given under live ultrasound guidance for pinpoint accuracy and comfort.

It distributes

Arthrosamid® distributes within the synovial fluid and begins to stick to and mesh with the synovial tissue.

2

It combines

Arthrosamid® permanently combines with the tissue lining your knee joint, thickening it to provide a barrier.

3

It relieves pain

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

Patients in the under 70 years group reported close to 80% positive response rate following treatment with Arthrosamid®.

The role of synovial pain

In osteoarthritis, the shock-absorbing cartilage wears away and the synovial tissue lining the joint becomes inflamed (synovitis). This synovial inflammation is strongly linked to the level of pain that knee OA patients experience.

Arthrosamid® works directly at this lining meshing with the synovial tissue to cushion the joint and reduce that pain, with a single injection.

Questions

FAQ's

Treatment with Arthrosamid may not be suitable for everyone. Speak to a qualified clinician or your doctor to advise you.

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, footwear and insoles, knee braces, oral pain relief medication, viscosupplement Hyaluronic Acid (HA) injections, and when these therapies fail joint replacement / knee surgery.

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

Clinical trials report there were no serious side effects following treatment with Arthrosamid®. The most commonly reported side effects were joint pain and a sensation of joint swelling, which were mostly mild in severity and lasting days to weeks.

The overall safety profile of the injectable hydrogel has been established over the last 20 years with its use for various indications in the body.
