Knee osteoarthritis (OA) affects millions, causing daily pain and reduced mobility. For years, patients have cycled through painkillers and steroid injections, feeling like surgery is the only endpoint.
Arthrosamid® is a unique, non-biodegradable hydrogel consisting of 97.5% water and 2.5% cross-linked polyacrylamide. Unlike traditional treatments that are absorbed, Arthrosamid® is a permanent implant that provides durable relief.
"Arthrosamid® integrates into the joint lining to create a cushion-like coating."
Understanding the difference between temporary relief and permanent joint preservation.
| Treatment | Longevity | Mechanism | Class |
|---|---|---|---|
| Steroid Injection | 3–6 Weeks | Anti-inflammatory | Temporary |
| Hyaluronic Acid | 3–6 Months | Lubrication | Absorbed |
| Arthrosamid® | 4+ Years | Scaffold / Coating | Permanent |
Arthrosamid® (PAAG) is 97.5% water and 2.5% cross-linked polyacrylamide.
As a permanent implant, it doesn't degrade, offering pain reduction sustained for up to 4 years after a single treatment.
A viable alternative for patients with "bone-on-bone" arthritis who want to postpone or avoid invasive knee replacement.
Backed by over 20 years of research in hydrogel technology and extensive clinical safety data.
We align our treatments with the latest evidence-based medicine, including support from the Canadian Orthopaedic Association (COA).
Clinical data from studies like Bliddal H, et al. (2021) shows significant improvements in WOMAC pain and function scores that are sustained long-term.
Innovative intra-articular injections are recognized as safe and effective non-surgical alternatives for patients who are not yet ready for total knee replacement.
The success of Arthrosamid® isn’t just about the gel—it’s about the delivery. Our protocol is a 4-step safety and precision process designed by Specialist MSK Radiologists.
Every patient undergoes a specialized MSK assessment to confirm joint capacity and synoyvial health.
Advanced ultrasound mapping ensures the gel is integrated precisely into the intra-articular space, avoiding soft tissues.
Rigorous clinical hygiene standards exceeding standard outpatient injection settings.
While Arthrosamid® tackles the pain, restoring function requires movement.
Regain trust in your knee joints as the chronic pain and stiffness subside post-treatment.
Engage in regular, low-impact exercises to strengthen the muscles supporting the joint.
Monitor your progress with our team at LSRI to ensure your recovery is tracking optimally.
At LSRI, the Arthrosamid® procedure takes about 20 minutes and is guided by advanced ultrasound to ensure the gel is deposited with 100% precision.
While highly effective, Arthrosamid® is not suited for everyone. Candidates should meet the following criteria:
