If you’re struggling with knee osteoarthritis (OA) pain, you may already know about treatments like cortisone shots, hyaluronic acid injections, or physical therapy. But what if there was a longer-lasting option that could help reduce pain for over a year with just one treatment? That’s where Arthrosamid® injections come in.

In this post, we’ll explain what Arthrosamid is, how it works, and why it’s considered superior to traditional treatments.

What Is Arthrosamid®?

Arthrosamid® is a new type of injection used to treat knee osteoarthritis. Unlike other treatments, it is made of a soft hydrogel (97.5% water, 2.5% polyacrylamide) that becomes part of your knee lining once injected.

• It cushions and supports the joint.
• It integrates with the knee tissue for lasting relief.
• It’s non-absorbable, meaning it doesn’t “wear off” quickly.

Because of this, one injection can provide pain relief that lasts for at least 12 months, with studies showing benefits up to two years.

Benefits of Arthrosamid Injections

• Long-lasting pain relief – most patients report less pain and stiffness for at least a year.
• Improved mobility – better function means walking, climbing stairs, and daily activities are easier.
• Safe and non-destructive – unlike repeated steroid shots, Arthrosamid does not damage cartilage.
• Delay or avoid surgery – many patients are able to postpone knee replacement thanks to the durable results.
• Single treatment – one injection under ultrasound guidance is usually enough.

How Arthrosamid® Works

When injected, Arthrosamid binds to the inner lining of the joint (the synovium). This creates a permanent cushioning effect, reducing friction and protecting the knee.

It’s different from other injections because it:

• Does not dissolve like hyaluronic acid.
• Does not cause cartilage damage like corticosteroids can.
• Provides ongoing support instead of just temporary pain masking.

Arthrosamid vs Other Knee Osteoarthritis Treatments

Arthrosamid vs Corticosteroid Injections (Cortisone Shots)

• Cortisone offers quick relief, but it usually lasts only a few weeks.
• Repeated cortisone injections may actually speed up joint damage.
• Arthrosamid offers sustained relief without harming the knee.

Arthrosamid vs Hyaluronic Acid (HA) Injections

• HA acts like a lubricant but typically lasts 4–6 months.
• Arthrosamid becomes part of the joint lining and lasts 12–24 months.
• Patients often need fewer repeat treatments with Arthrosamid.

Arthrosamid vs Physical Therapy

• Exercise and weight management remain the foundation of OA treatment.
• Physical therapy strengthens muscles but may not fully control pain.
• Arthrosamid helps patients feel well enough to keep moving, often enhancing PT results.

Who Can Benefit from Arthrosamid®?

Arthrosamid is suitable for people with:

• Mild to moderate knee osteoarthritis
• Persistent pain despite physiotherapy or medications
• A desire to avoid or delay knee replacement surgery

It’s especially helpful for patients who want a non-surgical option with longer-lasting results.

Safety and Side Effects

Clinical studies show Arthrosamid is safe, with only minor temporary side effects like mild swelling or discomfort at the injection site. Unlike steroids, it does not thin cartilage or accelerate arthritis progression.

FAQ About Arthrosamid® Injections

1. What is Arthrosamid used for?

Arthrosamid is an injectable hydrogel treatment for knee osteoarthritis. It cushions the joint lining, reducing pain and stiffness.

2. How long does Arthrosamid last?

Studies show one Arthrosamid injection can relieve knee pain for at least 12 months, with many patients reporting benefits lasting up to two years.

3. Is Arthrosamid better than cortisone injections?

Yes. Cortisone provides short-term relief but may harm cartilage with repeated use. Arthrosamid gives longer-lasting relief without damaging the joint.

4. What is the difference between Arthrosamid and hyaluronic acid injections?

Hyaluronic acid acts as a lubricant but usually lasts only 4–6 months. Arthrosamid integrates into the joint lining and provides support for 12–24 months.

5. Is Arthrosamid safe?

Clinical trials show Arthrosamid is safe, with only minor temporary side effects like mild swelling. Unlike steroids, it does not accelerate joint damage.

6. Who can benefit from Arthrosamid injections?

Adults with mild to moderate knee osteoarthritis, who still have pain despite physiotherapy or medications, may benefit most from Arthrosamid.

7. Can Arthrosamid delay knee replacement surgery?

Yes. Many patients find Arthrosamid helps control symptoms and maintain mobility, allowing them to postpone or avoid knee replacement.
