Is This For You?
Who is Arthrosamid For? Recognising the Ideal Candidate
You require a specialist assessment if you experience:
- Diminishing Returns from Other Treatments:
- Corticosteroid or hyaluronic acid injections no longer provide lasting relief.
- Desire to Avoid Surgery:
- You wish to delay knee replacement, are deemed too young for implants, or have medical comorbidities that make anaesthesia risky.
- Constant Daily Pain:
- You struggle to walk short distances without a limp or require walking aids. - Profound Joint Stiffness:
- Bending your knee to put on shoes is incredibly difficult; stiffness after sitting is severe. - Loss of Quality of Life:
- You are actively cancelling holidays or giving up low-impact sports like golf or cycling.
Understanding Your Condition
Where Arthrosamid Fits: The Orthopaedic Treatment Ladder
A responsible orthopaedic approach ensures treatments are scaled according to the severity of your cartilage loss.
1
Early Management
- Targeted physiotherapy, weight management, and activity modification.
2
Medical Interventions
- Use of NSAIDs and temporary ultrasound-guided corticosteroid injections for acute inflammation.
3
The Arthrosamid Window
- When osteoarthritis progresses and traditional injections fail, Arthrosamid bridges the gap, providing years of relief and successfully delaying prosthetic implants.
4
The Surgical Threshold
- When all joint-preserving options are exhausted, and cartilage loss is absolute, knee replacement becomes the final step.

Treatment Options
What is Arthrosamid®? The Science of Permanent Hydrogel
For decades, non-surgical options were limited to temporary steroid injections or short-acting hyaluronic acid. Arthrosamid completely redefines orthopaedic medicine.
The Hydrogel Technology
Arthrosamid is the first and only approved injectable treatment consisting of a 2.5% cross-linked polyacrylamide hydrogel.
Unlike traditional injections that are quickly absorbed and flushed out by the body, this hydrogel is permanent and will not degrade over time.
The Biological Integration
When injected, the hydrogel permanently combines with the knee’s synovial tissue (the inner lining of the joint capsule).
It significantly thickens the protective lining, acting as a permanent, physical shock absorber that spaces the joint and reduces bone-on-bone friction.
Arthrosamid Recovery Phase-Wise
Recovery is a partnership between the biological integration of the hydrogel and your commitment to brief, sensible rehabilitation.
Phase 1 (Immediate Post-Injection):
Walk out of the clinic unassisted. Temporary mild swelling or a sensation of "fullness" is normal. Focus on resting and avoiding unnecessary strain.
Phase 2 (Integration Phase):
Avoid heavy lifting, deep squatting, and high-impact exercises.
Allow the hydrogel to successfully weave into the synovial joint tissue without displacement.
Phase 3 (Symptom Relief):
The biological cushioning effect matures over this window.
Joint stiffness drastically decreases; significant pain relief is clinically realized.
Phase 4 (Returning to Life):
Fully cleared to return to normal daily activities.
Resume recreational sports, golf, and travel without chronic osteoarthritic pain.

Common Question
Common Questions Patients Ask In Clinic
How long does it take to feel the effects of Arthrosamid?
Arthrosamid can take between four weeks and three months to reach its full potential. While some patients experience immediate relief from the mechanical cushioning, the full biological integration takes several weeks to manifest.
Are there any activity restrictions following treatment?
Can Arthrosamid delay the need for knee replacement surgery?
How is this different from a steroid or hyaluronic acid injection?
Is the injection painful?
