About Arthrosamid

Arthrosamid is a non-surgical, long-acting injectable treatment consisting of a non-biodegradable hydrogel (97.5% water and 2.5% cross-linked polyacrylamide). 

• Mechanism: It is injected directly into the knee joint's synovial cavity, where it cushions the joint and integrates with the tissue lining to reduce pain and stiffness.
• Benefits: It offers a minimally invasive alternative to surgery, with effects proven to last up to three to five years post-treatment.
• Procedure: Performed in an outpatient setting under local anaesthesia, typically taking about 15–30 minutes.
• Cost: At The Horder Centre, private treatment starts from approximately £2,884 for a single knee.
