Arthrosamid Knee Injection in London
Arthrosamid injections are a new type of treatment for knee osteoarthritis. This is an alternative injectable treatment to Hyaluronic acid, PRP or cortisone injections. Arthrosamid is a non-biodegradable hydrogel. When injected into the knee Arthrosamid cushions the joint and reduces pain, providing safe and sustained relief, all with one injection. If you are suffering with pain stiffness and swelling in your knee, an Arthrosamid injection may help prevent having to have joint replacement surgery imminently.

What is Arthrosamid?
Arthrosamid is an innovative non-biodegradable hydrogel that is 2.5% cross-linked polyacrylamide and 97.5% water. When injected into the knee inner joint cavity, it restores viscosity within the synovial fluid (joint fluid), improving lubrication and cushioning of the joint. Arthrosamid also integrates into the synovium (joint lining) of the inner joint capsule creating a cushion-like effect.
What are the benefits of Arthrosamid?
An Arthrosamid knee injection works to cushion the joint and reduce the symptoms of osteoarthritis. It can reduce your pain, decrease stiffness, and help movement. It has been shown to be safe and can give long-acting pain relief in the treatment of knee arthritis.

Arthrosamid is injected into the knee joint with ultrasound-guidance. It is performed by an expert clinican used to performing hundereds of knee injections every year. Arthrosamid is injected with local anaesthetic so the procedure can be very comfortable.

What are the risks and Possible side effects?
Post injection flare
A minority of people find a temporary increase in pain for 24-48 hours post injection. This is entirely normal and can be helped with paracetamol, rest and ice. We also suggest avoiding driving to/from your appointment, in case you have any post injection soreness.
Infection
Due to the nature of the needle breaking the skin, there is a very small; chance of infection (1:50, 000). All our injections are done using sterile equipment, with the upmost attention paid to maintaining high standards of cleanliness and safety. If the injected area becomes hot/swollen/painful, you should seek urgent medical attention.
I take other medicines. Can I still have an Arthrosamid injection?
The majority of patients will still be able to have an Arthrosamid injection if they take other medicines. There are a few exceptions that the clinician must first check before it is safe to proceed. If you are taking a blood thinning drugs we will check the type and timing of your medication before any injection.
