Arthrosamid® injections are a cutting-edge, non-surgical treatment option for people with knee osteoarthritis, persistent knee swelling, or ongoing knee pain that has not responded to traditional injections. At Wandsworth Physiotherapy, Arthrosamid is offered through our specialist Knee Pain Clinic or Ultrasound Guided Injection Clinic, combining advanced imaging, expert assessment and evidence-based rehabilitation.
If steroid injections or hyaluronic acid (HA) injections have only provided short-term relief — or if knee replacement has been suggested as premature — Arthrosamid may offer a longer-lasting alternative.
Arthrosamid® is a polyacrylamide hydrogel injectable implant designed specifically for use in knee osteoarthritis.
Unlike hyaluronic acid injections, which gradually break down over several months, Arthrosamid is non-biodegradable. Once injected, it integrates with the synovial lining of the knee joint and remains in place long term.
The hydrogel is made up of approximately 97.5% water and 2.5% cross-linked polymer, allowing it to behave like a soft, stable cushion within the joint. This structure helps to modulate inflammation and provide longer lasting relief from knee pain.
