Safe & Established
Built on 20+ years of hydrogel research with a favorable safety profile.
HISTORY OF ARTHROSAMID®
Arthrosamid®’s story started two decades ago. The brainchild of the team at Contura, the product had been in human use for various indications since 2000, and a favourable safety profile had already been established.

Clinical Innovation
Arthrosamid®: A defining breakthrough in OA treatment.
Developed over two decades, this non-biodegradable hydrogel offers a durable, minimally invasive alternative to cushion the joint and relieve pain.
CE Marked
Approved in Europe (2021) for symptomatic treatment of knee osteoarthritis.
Delays Surgery
Joint-preserving injection intended to provide long-acting pain relief.
Treatment Overview
What is Arthrosamid®?
A breakthrough single-injection treatment designed specifically for patients suffering from knee osteoarthritis.
Single Intra-articular Injection
Administered directly into the knee cavity to cushion the joint, providing sustained relief from pain and stiffness.
Non-biodegradable Hydrogel
Composed of 2.5% cross-linked polyacrylamide and 97.5% water. It integrates with the tissue rather than degrading over time.
Alternative to Existing Therapies
A viable option for patients where conventional therapies (like standard HA injections) have failed to provide lasting relief.
Mechanism of Action
How does Arthrosamid® work?
Restoring cushioning and lubrication directly inside the knee joint capsule.
Step 01
Precise Injection
Arthrosamid® is injected into the inner joint cavity (synovial space) under image guidance.
Step 02
Integration
The hydrogel combines with synovial fluid and integrates into the lining of the joint capsule.
Step 03
Cushioning
Forms a durable, cushion-like layer that reduces stiffness and improves overall mobility.
Clinical Note: The procedure is performed by a qualified clinician. Ultrasound or X-ray guidance is used to ensure the hydrogel is delivered accurately into the joint space for maximum effectiveness.
Patient Outcomes
What are the benefits?
Long-acting pain relief and improved mobility from a single injection.
Reduced pain & stiffness
Reduced pain, less stiffness and easier movement as the joint is cushioned.
Long-acting relief
Long-acting relief from a non-degradable hydrogel that is designed to stay in the joint.
Potential to delay surgery
For some people, Arthrosamid® may help postpone or potentially avoid knee surgery.

Safety & Tolerability
Is Arthrosamid® safe?
A hydrogel with over 20 years of clinical use history.
20+ years of clinical use
The hydrogel technology has been used in humans since 2000 for different indications, with a favourable safety profile.
No serious side effects
In clinical trials, no serious side effects were reported that were linked to the hydrogel itself.
Mild, temporary reactions
Common side effects were mild to moderate pain or swelling around the injection site, generally short-lived.
Safety Profile Summary
Overall, the hydrogel’s safety profile has been confirmed across multiple uses in the body. Your clinician will review your medical history and explain potential risks and benefits before treatment.
*As with any medical procedure, individual experiences vary. Always follow the advice of your healthcare professional and report any unexpected symptoms after your injection.
Recovery & Activity
When can I get back to normal activity?
A short recovery period with guidance from your clinician.
Do
As advised by your professional
Resume light everyday activities when your clinician says it is safe to do so.
Take short, gentle walks around your home or workplace as tolerated.
Listen to your knee, rest when needed and follow any aftercare advice from your clinic team.
Avoid
First few days (follow advice)
Strenuous weight-bearing exercise such as running, tennis or high-impact classes.
Long walks, hikes or standing for prolonged periods soon after the injection.
Heavy lifting, deep squats or sudden twisting movements until your clinic team advises they are safe.
Note: Everyone recovers differently. Your healthcare professional will give you personalised guidance on when and how to increase your activity after Arthrosamid®.
