An injectable alternative for long-lasting pain relief
When conventional treatments (painkillers, injections, rehabilitation) are no longer sufficient, but surgery still seems premature, the’Arthrosamid® represents a promising therapeutic option for patients suffering from moderate to advanced osteoarthritis.
Unlike traditional products such as hyaluronic acid, Arthrosamid® is non-biodegradable and designed to remain in the joint long-term.
This particularity makes it an innovative solution, capable of offering a prolonged effect and a new approach in the management of osteoarthritic pain.
It is aimed at patients who wish to avoid or postpone the fitting of a prosthesis, while regaining comfort and mobility in their daily lives.
Unlike conventional injections which need to be repeated every 6 to 12 months, a single injection of Arthrosamid® can be effective for 2 to 5 years depending on the patient.
Dr. Coulin offers this treatment as part of a personalized approach, after clinical evaluation and imaging, to ensure that each patient is a suitable candidate for this solution.
What is Arthrosamid®?
This 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, it acts 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 absorbable products, this solution remains active in the joint for several years. It thus acts as a long-lasting cushion that reduces chronic pain and improves mobility.
For which patients is this treatment indicated?
Dr. Coulin offers this treatment to patients presenting with:
- A knee osteoarthritis moderate to advanced, 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 administered directly during the consultation, under sterile and secure conditions. The procedure is performed under ultrasound guidance, 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 injections, this treatment stands out for its longevity and 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 tolerability.
It is emerging as a new therapeutic approach, positioned between conservative treatments and prosthetic surgery. In line with the principles of sustainable medicine, it allows for the preservation of the joint and the extension of quality of life without the immediate need for a prosthesis.
Do you want to avoid surgery but regain comfort?
If you suffer from osteoarthritis of the knee, and 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.
