Scientific Evidence
Arthrosamid® has been shown to exceed the minimum clinically important difference (MCID) of 9 points for knee osteoarthritis outcomes, with improvements maintained for up to 5 years after a single injection.
How Arthrosamid® Works
Arthrosamid® is a unique, non-biodegradable hydrogel. Once injected into the knee joint, it integrates with the synovium (joint lining), creating a cushioning effect and restoring lubrication. Unlike temporary treatments, Arthrosamid® becomes a permanent part of the soft tissue, continuing to protect and support the joint over time.
Clinical studies have shown significant pain reduction and improved joint function, with benefits sustained beyond 3 years—and in many cases lasting up to 5 years.
Clinical Outcomes
Patients treated with Arthrosamid® frequently report:
- Noticeable and lasting pain reduction
- Improved joint mobility and flexibility
- Greater ease with daily activities
- Enhanced confidence in movement and exercise
This evidence-based treatment is transforming how osteoarthritis is managed, offering patients renewed independence without major surgery.
Safety & Side Effects
Arthrosamid® has undergone extensive clinical research and is considered a safe option for suitable patients. Reported side effects are generally mild and temporary, including short-lived discomfort at the injection site or minor swelling, which usually resolves without intervention.
