Hydrogel is a ground-breaking new treatment option for arthritis in dogs. The hydrogel injection that we use at Physio-Vet is Arthramid Vet. This is a sterile gel that we can inject into joints because it is compatible with the body’s biology. Arthramid Vet is composed of water and cross-linked 2.5% polyacrylamide.
The hydrogel properties enable it to stick to the joint lining known as the synovium. Over the next two weeks it starts to become incorporated into this lining, as well as the neighbouring layer of joint capsule, acting as a scaffolding. This helps to develop an absorbent cushion within the joint and improves the quality of joint fluid. Hydrogel also makes the joint capsule stronger and more elastic. These benefits help load-bearing through the joint, and reduce inflammation.
