At Mersea Road Clinic, we are pleased to help patients access Arthrosamid® injections for knee osteoarthritis through our local referral partnership with Fortis Health & Wellbeing in Langham, Colchester.
If you are struggling with ongoing knee pain, stiffness or reduced mobility caused by osteoarthritis and would like to find out whether Arthrosamid® may be suitable for you, contact Mersea Road Clinic and we can arrange your consultation for you.

Arthrosamid® is an injectable hydrogel treatment for the symptomatic treatment of knee osteoarthritis in adults.
Unlike corticosteroid or hyaluronic acid injections, Arthrosamid® is a non-absorbable polyacrylamide hydrogel implant. It consists of 97.5% sterile water and 2.5% cross-linked polyacrylamide and is injected directly into the knee joint.
Following injection, the hydrogel integrates with the synovial tissue lining the joint. This is designed to help improve the properties of the joint lining and can result in reduced pain and improved function.
Arthrosamid® offers a minimally invasive, non-surgical option for the longer-term management of symptoms associated with knee osteoarthritis.
Knee osteoarthritis can have a significant effect on everyday life.
You may experience:
Persistent or recurring knee pain
Stiffness
Pain when walking
Difficulty climbing stairs
Reduced mobility
Swelling
Difficulty exercising
Problems carrying out everyday activities
For some people, exercise, physiotherapy, medication or other injection therapies provide sufficient relief. For others, symptoms continue despite these treatments.
Arthrosamid® provides another treatment option for people looking to manage the symptoms of knee osteoarthritis.
Clinical studies have reported meaningful improvements in pain following a single Arthrosamid® injection, with improvements maintained in study participants for up to five years.
Individual results vary. Arthrosamid® does not cure osteoarthritis and improvement cannot be guaranteed.
Osteoarthritis involves more than simply the wearing of cartilage within the knee.
The synovium, the tissue lining the inside of the knee joint, can also play an important role in inflammation, stiffness and pain.
After Arthrosamid® is injected into the knee, the hydrogel becomes integrated with this synovial tissue.
It is designed to mechanically soften and increase the elasticity of the joint lining, helping to reduce the symptoms associated with knee osteoarthritis.
Because Arthrosamid® is non-biodegradable, the hydrogel is not gradually broken down and absorbed by the body in the same way as some other injectable treatments.
We believe patients should have clear information about the likely cost of treatment before deciding whether they would like a consultation.
There is no obligation to proceed with treatment following your consultation.
Prices shown are the current prices charged by the treating clinic and may be subject to change. Mersea Road Clinic will confirm the current price when arranging your referral.
Simply call us on 01206 548899 and tell our reception team that you would like to enquire about Arthrosamid®.
We can take your details and arrange the next step for you.
Mersea Road Clinic will arrange your consultation with our local treatment partner:
Fortis Health & Wellbeing
Suite 14, Park Lane Business Centre
Park Lane
Langham
Colchester
CO4 5WR
Your consultation gives the injection specialist an opportunity to discuss:
Your knee symptoms
Your medical history
Previous treatments
Previous injections or surgery
Your current medication
Your expectations from treatment
Whether Arthrosamid® is clinically appropriate for you
The consultation is free and there is no obligation to proceed with treatment.
If you and the treating clinician decide that Arthrosamid® is appropriate, your treatment will be arranged at Fortis Health & Wellbeing in Langham.
The injection is carried out by a qualified injection specialist and is performed using ultrasound guidance.
Arthrosamid® injections are not performed at Mersea Road Clinic.
An injection does not necessarily replace the other elements involved in managing osteoarthritis.
Depending on your individual circumstances, ongoing exercise, strengthening, physiotherapy, mobility work, weight management or other musculoskeletal care may still be recommended.
Our multidisciplinary team at Mersea Road Clinic can continue to support your musculoskeletal health and rehabilitation where appropriate.
Arthrosamid® may be worth discussing if you are an adult experiencing symptoms associated with knee osteoarthritis, particularly if:
Knee pain is affecting your everyday activities
Walking or using stairs is becoming difficult
Your knee feels persistently stiff
Exercise or physiotherapy alone has not provided sufficient relief
Previous treatments are no longer providing adequate relief
You want to investigate alternatives to repeated injections
You are looking for non-surgical treatment options
You want to explore your options before considering surgery
You do not need to decide for yourself whether you are suitable.
That is the purpose of the clinical consultation.
No. Arthrosamid® is not appropriate for every patient.
There are circumstances in which treatment should not be performed or additional precautions may be necessary. These can include certain infections, significant inflammation, previous procedures or implants within the knee and particular medical conditions.
This is why every patient receives an appropriate clinical assessment before treatment.
Please tell the injection specialist about all medications, medical conditions, previous knee injections and previous knee surgery during your consultation.
As with any injection into a joint, side effects and complications are possible.
Reported effects following Arthrosamid® treatment can include temporary:
Knee or injection-site pain
Swelling
A feeling of fullness or swelling within the joint
Formation or swelling of a Baker's cyst
Infection is a rare but important potential complication of any joint injection.
The treating clinician will discuss the potential benefits, risks, precautions and aftercare with you before you consent to treatment.
