Long-lasting relief for knee osteoarthritis.
Arthrosamid® is a new, long-acting injectable hydrogel treatment for knee osteoarthritis. It works by forming a soft, cushioning layer inside the joint to reduce friction and ease pain — often after just one injection.
Arthrosamid is used to treat pain from knee osteoarthritis (OA). It may be suitable for people with mild to moderate OA who still have symptoms despite lifestyle measures, physiotherapy, or other injections such as corticosteroids or hyaluronic acid.
A trained clinician injects 6 ml of Arthrosamid directly into the knee joint under ultrasound guidance. The procedure takes around 15–20 minutes, with minimal discomfort, and patients can usually walk out immediately afterwards.
Clinical studies show that a single Arthrosamid injection can provide meaningful and lasting pain relief, with benefits maintained for several years.
| Study Duration | Key Findings |
|---|---|
| 1 year | Pain scores reduced by about 25%; 62% of patients experienced meaningful pain relief. |
| 3 years | Ongoing reduction in pain and stiffness, improved function, and good tolerability. |
| 4–5 years | Sustained benefit and consistent safety profile. |
| 10 years (safety) | Very few reported adverse effects; no unusual reactions during later knee surgery. |
Arthrosamid has been used in clinical studies for more than a decade and has shown a very good safety record. Side effects are generally mild and short-lived, such as temporary swelling or mild discomfort in the injected knee.
It contains no animal proteins, and allergic reactions are rare.
Most people can resume normal light activity immediately. Avoid strenuous exercise for a few days. Mild swelling or aching may occur for 24–48 hours. Pain relief often begins within a few weeks and may continue to improve over several months as the hydrogel integrates into the joint.
