Living with knee osteoarthritis can wear you down in ways other people do not always see. We understand that it is not just about the pain itself. It is the hesitation before using the stairs, the stiffness when you stand up, the walks you cut short, and the small daily movements that suddenly feel like hard work.
When you come to us for an Arthrosamid injection in London, the aim is simple: to help you move more comfortably and, where appropriate, delay surgery for as long as possible. At RAD Clinics, we offer Arthrosamid as an advanced, minimally invasive treatment for suitable patients with knee osteoarthritis, supported by specialist assessment and ultrasound-guided care.
What Exactly is an Arthrosamid Injection and How Does It Work?
An Arthrosamid injection is a treatment for knee osteoarthritis that uses a sterile polyacrylamide hydrogel. In simple terms, it is a gel-like implant injected into the knee joint, where it integrates with the synovial tissue. The goal is to create a soft cushioning effect inside the joint, improve lubrication, reduce friction, and help ease pain linked to osteoarthritis.
Unlike some other joint injections, Arthrosamid is described as non-degradable, meaning it is designed to remain in place rather than being broken down quickly over time.
We know that difference matters to many of our patients. Steroid injections and some other options may help for a shorter period, but Arthrosamid is intended to provide more prolonged structural support within the knee. Published follow-up data have shown ongoing improvements in pain and function after a single injection in people with knee osteoarthritis, although results can vary from person to person.
Am I a Suitable Candidate for Arthrosamid Injections for Knee Arthritis?
At RAD Clinics, we mainly offer this treatment to people with knee osteoarthritis, especially those with mild to moderate wear and tear who want a non-surgical option and may be hoping to delay knee replacement surgery. It is not the right treatment for every painful knee, which is why we always start with a proper assessment.
Our first step is a face-to-face consultation, which is mandatory and currently costs £160. This includes triage for the procedure, an ultrasound scan and a report. This helps us decide whether an Arthrosamid knee injection is likely to be appropriate and safe for your specific condition, because the right treatment starts with the right diagnosis.
What Does the Arthrosamid Knee Injection Procedure Involve?
We find that many patients feel more comfortable once they know what actually happens on the day. At RAD Clinics, we arrange a separate 30-minute antibiotics appointment, which is included in the overall treatment cost.
We then clean the knee area carefully, and a local anaesthetic may be used to make the procedure more comfortable. A fine needle is used to place the hydrogel into the joint.
At RAD Clinics, the whole process includes your antibiotics appointment and a second appointment of around 30 to 45 minutes for the procedure, usually organised on the same day. Most patients are able to return to light activity shortly afterwards, which is one reason many people choose this less disruptive treatment route.
Why Does RAD Clinics Use Ultrasound-Guided Arthrosamid Injections?
At RAD Clinics, we use ultrasound-guided Arthrosamid injections to help place the treatment accurately within the knee joint. Ultrasound gives us a live view of the area during the procedure, helping us deliver treatment with precision while avoiding nearby structures.
For our patients, that added precision can bring greater confidence in the process. It supports accurate delivery, better distribution of the hydrogel in the intended area, and a treatment approach built around safety as well as comfort.
What Are the Key Benefits and Possible Arthrosamid Side Effects?
At RAD Clinics, we offer Arthrosamid injections for knee arthritis as a treatment that may provide long-term relief from just one procedure, although results can vary between individuals. Potential benefits include:
- Prolonged pain relief
- Improved joint lubrication
- Reduced friction inside the knee, a minimally invasive alternative to surgery, faster recovery with little downtime for many patients
Temporary discomfort can happen after the injection, including mild pain, swelling or stiffness for a few days. Serious complications are uncommon, but every procedure carries some level of risk, which is why we place such importance on careful assessment and aftercare.

Do Arthrosamid injections work?
Studies and clinical use suggest that Arthrosamid can help reduce pain and improve function in suitable patients with knee osteoarthritis, but outcomes vary, and no injection can guarantee the same result for everyone.

Arthrosamid is designed as a non-degradable hydrogel implant, and published follow-up studies have reported sustained benefit over months to years after a single injection.
