An injectable alternative for long-lasting pain relief
When conventional treatments (painkillers, injections, rehabilitation) are no longer sufficient, but surgery still seems premature, Arthrosamid® represents a promising therapeutic option for patients with moderate to advanced osteoarthritis.
Unlike traditional products like hyaluronic acid, Arthrosamid® is non-biodegradable and designed to remain in the joint for the long term. This makes it an innovative solution, capable of offering a prolonged effect and a new approach to the management of osteoarthritis pain.
What is Arthrosamid®?
Arthrosamid® is a new-generation injectable treatment for knee osteoarthritis. It is a hydrogel based on polyacrylamide, a biocompatible polymer composed of 97.5 % water.
Injected directly into the knee joint, Arthrosamid® works in two ways:
- He partially replaces synovial fluid, this natural lubricant of the joints.
- He creates a protective barrier which acts as a shock absorber and improves joint function.
Unlike resorbable products, Arthrosamid® remains active in the joint for several years. It thus acts as a durable cushion which reduces chronic pain and improves mobility.
For which patients is Arthrosamid® indicated in Geneva?
Dr. Coulin proposes treatment by Arthrosamid® to patients with:
- A moderate to advanced knee osteoarthritis, confirmed by imaging.
- A lack of response to classic infiltrations (hyaluronic acid, PRP).
- A desire to avoid or postpone the fitting of a prosthesis.
- The need to regain comfort and mobility without surgery.
This treatment is suitable for both active patients wishing to extend their independence and those with contraindications to surgery. Arthrosamid® is therefore a choice alternative in a personalized care pathway.
How is the injection performed?
The injection is performed directly in consultation, under sterile and secure conditions. The procedure is performed under ultrasound control, guaranteeing maximum precision.
The protocol:
- Single injection of Arthrosamid® into the knee joint.
- No general anesthesia required.
- Post-injection monitoring for a few minutes.
- The patient can walk immediately afterward, with a recommendation of 48 hours of joint rest.
This simplicity makes it a lightweight and accessible option, without hospitalization or heavy recovery.
What results can be expected from Arthrosamid® treatment?
The positive effects appear gradually, usually between 4 and 6 weeks after the injection. They continue to improve over the months.
The benefits observed are:
- A significant reduction in pain linked to osteoarthritis.
- A improved joint mobility, making everyday actions easier.
- A reduction in the consumption of painkillers.
- A lasting effect, which can last up to 5 years depending on the patient.
Compared to other infiltrations, Arthrosamid® stands out for its longevity and its effectiveness in advanced osteoarthritis.
Arthrosamid® or other injections: which to choose?
| Treatment | Duration of effectiveness | Frequency | Main indications |
| Hyaluronic acid | 6 to 9 months | 1 to 3 | Mild to moderate osteoarthritis |
| PRP (platelet-rich plasma) | 6 to 12 months | 1 to 2 | Early osteoarthritis, chronic pain |
| Stem cells (BMC) | 12 to 24 months | 1 | Localized osteoarthritis in young patients |
| Arthrosamid® | 2 to 5 years | 1 | Moderate to severe osteoarthritis, lasting without surgery |
Dr. Coulin helps each patient choose the best option, based on the tests, the stage of the disease and the functional goals.
An innovative, clinically validated treatment
Arthrosamid® is authorized in Europe and used in several specialized centers. Numerous clinical studies have demonstrated its efficacy and tolerance.
It stands out as a new therapeutic route, between conservative treatments and prosthetic surgery. In a sustainable medicine approach, it allows the joint to be preserved and the quality of life to be prolonged without immediately resorting to a prosthesis.
Dr. Coulin integrates Arthrosamid® into a comprehensive treatment approach, including precise diagnosis, comprehensive imaging and personalized follow-up.
Do you want to avoid surgery but regain comfort?
If you suffer from knee osteoarthritis, if conventional treatments are no longer sufficient and you wish to regain mobility and comfort without resorting to a prosthesis, Arthrosamid® may be the solution.
Dr. Coulin will see you for a consultation in Geneva to analyze your situation, evaluate your tests and offer you the most appropriate treatment.
