Arthrosamid® is a cutting-edge permanent injectable hydrogel that delivers long-lasting, proven pain relief for knee Osteoarthritis - improving your quality of life without surgery.
The first and only approved injectable treatment that permanently combines with the knee’s synovial tissue, Arthrosamid® decreases joint stiffness, diminishes pain, improves the function of the knee, and enhances your quality of life.
Arthrosamid® is administered via a simple, one-step procedure performed under local anaesthesia by a qualified physician familiar with joint injections ensuring you’re in and out of the clinic the same day.
Arthrosamid® is singularly injected into your knee’s synovial cavity where it distributes within the synovial fluid and begins to stick to and mesh with the synovial tissue.
Before treatment with Arthrosamid®, you will have a local anaesthetic to numb the area around your knee. You will also be given antibiotics ahead of this to protect you from any potential risk of infection.
Step 1: Your knee will be cleaned prior to treatment.
Steps 2 & 3: Arthrosamid® is then singularly injected into your knee’s synovial cavity. This might be performed with the help of ultrasound.
Step 4: The needle is then removed and a plaster is placed over the injection site.
What should I expect immediately after treatment with Arthrosamid®?
Following the procedure, you may be allowed to leave the clinic immediately, or you may wish to rest until you feel ready to go.
Your knee may start to feel uncomfortable as the anaesthetic wears off, but many patients do not report any discomfort.
If you do feel discomfort, symptoms may include mild to moderate pain and/or swelling at the injection site. If your knee becomes red, hot, largely swollen or more painful, you should immediately contact your Arthrosamid® physician for treatment.
You should continue your regular medication and pain killers as normal.
Please note, receiving Arthrosamid® may feel like a different sensation to other treatments that you have previously experienced as it is more viscous than other injectables.
Treatment with Arthrosamid® remains safe and effective for its intended use five years after single injection. To date, thousands of patients have been treated with Arthrosamid® in more than 220 clinics across Europe.
Frequently asked questions about Arthrosamid®
Clinical trials report there were no serious side effects following treatment with Arthrosamid®. The most commonly reported side effects were joint pain and a sensation of joint swelling, which were mostly mild in severity and lasting days to weeks.
The overall safety profile of the injectable hydrogel has been established over the last 20 years with its use for various indications in the body.
Structured rehabilitation will aid recovery following your treatment with Arthrosamid®. Please discuss this with your clinician. Resources for rehabilitation are also available free of charge on the Arthrosamid® website.
You are likely to feel some pain relief within 24 hours; however, it can take four to twelve weeks to feel the maximum benefit. Clinical data shows that most patients start to feel an effect within a few weeks.
As with any invasive joint procedure, it is recommended to avoid strenuous activity (e.g. tennis, jogging or long walks) during the first few weeks after the injection and begin rehabilitation activities when possible.
Whilst trials have not been conducted to show treatment effect, future treatments with Arthrosamid® are not contraindicated and can be discussed with your doctor or physician.
Yes, it is possible to have both knees treated with Arthrosamid® but your physician is best placed to decide the time period before the treatments.
If in the future you require a major surgical or dental procedure, you should tell your treating physician that you have an Arthrosamid® injectable implant in your knee to ensure an accurate medical assessment.

Why choose Arthrosamid® and what are the benefits?
No therapies have been able to satisfactorily halt or delay OA progression or provide effective, long lasting symptomatic relief for patients with knee OA. So, until now, treatments have tended to focus on pain relief and the management of symptoms through options such as weight loss, exercise and physiotherapy, walking aids, knee braces, pain relief medication and as a last resort knee surgery..
Unlike with HA injectables — where there is very little evidence to show that the effect is still noticeable at six months — Arthrosamid® provides a significant reduction in your knee OA pain over a longer period with one single treatment.
Treatment with Arthrosamid® is a simple, one-step out-patient procedure — which doesn’t involve the disruptive recovery period usually associated with surgery.
Patients in the under 70 years group reported close to 80% positive response rate following treatment with Arthrosamid®.
“I wanted to send a good news update that Prof Wilson and Mr Van Heerwarden might be interested in!
I played in a masters ITF tennis clay court event in Wimbledon last week and won the singles.
This is my first masters ITF since the double osteotomy surgery last year!”

Danny, 26 years old, is very active.
He had a long long standing deformity with a significantly knocked knee. His knee cap has been sitting in the wrong position which has caused premature osteoarthritis of the knee cap area.
He underwent arthroscopy and a distal femoral medial closed wedge osteotomy.
The leg is now well aligned after the surgery and had minimum pain post osteotomy.
“Just wanted to drop you a note to thank you so much for operating on Danny last Friday. He is in such good form and surprisingly without pain, hardly so amazing. Genuinely appreciate you and Kristian doing what you do.
Best wishes, John”

I had three procedures carried out under the care of Professor Wilson in 2022. One was a lateral meniscus repair on my left knee, while the other two were high tibial closing wedge osteotomies on both knees. I could not recommend Professor Wilson and his supporting team highly enough. The quality of care was excellent and the communication both before and after each operation was first class.
