Arthrosamid vs PRP for Knee Osteoarthritis
PRP and Arthrosamid are different private knee injection approaches. Patients comparing PRP and Arthrosamid should understand that these treatments do not have the same material, mechanism, treatment course or evidence discussion. The right option depends on the diagnosis and the treatment goal.
Arthrosamid vs PRP
| Question | PRP | Arthrosamid |
|---|---|---|
| Material | Patient's own blood processed to concentrate platelets | Manufactured hydrogel: 97.5% water and 2.5% polyacrylamide |
| Treatment type | Regenerative/orthobiologic injection option | Non-biodegradable hydrogel knee injection |
| Course | Protocol-dependent | Single-injection protocol |
| Fit | Depends on diagnosis and treatment plan | Selected knee osteoarthritis patients after assessment |
| Claim limit | Do not promise cartilage regeneration | Do not promise a cure or surgery avoidance |
| Decision basis | Clinical assessment | Clinical assessment, history, and imaging review where available |
How To Choose The Discussion
The discussion should start with diagnosis: is the pain definitely osteoarthritis, and do symptoms and imaging support that? It should then compare whether a regenerative-style PRP discussion or a hydrogel Arthrosamid discussion fits the patient's goals, previous injection response, side effects, and timing. The most important outcome should be made explicit, whether that is walking, stairs, stiffness, sport, work, or sleep.
Is PRP better than Arthrosamid?
There is no universal answer. They are different treatment categories and should be compared during assessment.
Does PRP regrow cartilage?
PRP should not be sold as guaranteed cartilage regeneration.

Book a consultation if you are comparing PRP and Arthrosamid and want a clinician-led recommendation rather than a product-led decision.
Assessment first. Injection only where it is clinically appropriate.
