The Procedure
Arthrosamid® is given as a single injection under local anaesthetic, typically carried out as a day case with no overnight stay required.
Comparing Knee Osteoarthritis Treatment Options
How Arthrosamid® compares to hyaluronic acid and steroid injections.
| Treatment Option | Primary Mechanism | Relief Duration | Repeat Frequency |
|---|---|---|---|
| Arthrosamid® Hydrogel | Integrates into the synovial membrane; permanent cushioning & elasticity | Multi-year relief (clinical trial data up to 3–5 years) | Single injection |
| Hyaluronic Acid (HA) | Temporarily lubricates joint fluid | 6 to 12 months | Requires repeat sessions every 6–12 months |
| Steroid Injections | Suppresses acute joint inflammation | 4 to 12 weeks | Used primarily for short-term flare-ups |
Clinical Evidence & Safety
- Mechanism of Action: the 2.5% polyacrylamide hydrogel integrates with the synovial lining over 4 to 12 weeks.
- Clinical Longevity: designed as a single, non-biodegradable injection intended to provide sustained relief - your doctor can discuss expected duration for your individual case at consultation.
- Clinical Accuracy: injections are delivered under local anaesthetic using precision ultrasound guidance.
