An injectable alternative for long-lasting pain relief
When conventional treatments (analgesics, injections, rehabilitation) are no longer sufficient, but surgery still seems premature, Arthrosamid® represents a promising therapeutic option for patients suffering from moderate to advanced knee osteoarthritis.
Unlike traditional products like hyaluronic acid, Arthrosamid® is non-biodegradable and designed to remain in the joint long-term, offering a prolonged effect and a new approach in the management of osteoarthritis pain.
What is Arthrosamid®?
Arthrosamid® is a new-generation injectable treatment for knee osteoarthritis. It is a hydrogel made from polyacrylamide, a biocompatible polymer composed of 97.5 % water. Arthrosamid is injected directly into the joint to partially replace synovial fluid and create a protective barrier within the joint.
This product remains active for several years and acts as a natural shock absorber, reducing chronic joint pain.
For which patients is Arthrosamid® indicated in Geneva?
Dr. Coulin recommends Arthrosamid® for patients:
- Having moderate to advanced knee osteoarthritis
- No longer responding to classic infiltrations (hyaluronic acid, PRP)
- Wishing to avoid or postpone the fitting of a prosthesis
- Wanting to regain comfort and mobility without surgery
This treatment is particularly suitable for active patients or those with contraindications to surgery.
How is the injection performed?
The injection is performed in consultation, under ultrasound control for maximum precision.
The protocol:
- Single injection into the knee joint
- No general anesthesia required
- Post-procedure monitoring for a few minutes
The patient can walk immediately after the injection, but 48 hours of joint rest is recommended.
What results can be expected from Arthrosamid® treatment?
Positive effects are typically felt between 4 and 6 weeks after injection, with continued improvement over several months.
In particular, we note:
- A significant reduction in knee pain
- Better joint mobility
- A reduction in the consumption of painkillers
- A lasting effect of up to 5 years
