A Non-Surgical, Single-Injection Option for Knee Osteoarthritis.

Arthrosamid® is an injectable hydrogel that integrates with the knee joint to support long-lasting symptomatic relief, performed in-clinic by a Group23 physician under local anaesthetic and ultrasound guidance.

What is Arthrosamid®?

An injectable hydrogel, 2.5% cross-linked polyacrylamide and 97.5% water, developed to treat the symptoms of knee osteoarthritis. Unlike treatments absorbed by the body, it integrates into the knee’s synovial tissue to cushion the joint.
  • First and only approved injectable implant for knee OA
  • Single procedure under local anaesthetic
  • Long-lasting symptomatic relief

How Arthrosamid® Works?

1
Initial Injection.

Once injected, Arthrosamid disperses in the synovial fluid and is cleared into the synovial lining of the joint.

2
Lasting Integration.

Its presence in the synovial membrane helps restore elasticity and cushion the joint, supporting long-lasting relief.

Benefits, Safety and Common Questions

How long does relief last?
Polyacrylamide does not degrade and can provide significant relief for up to 5 years; relief typically begins within 4 to 12 weeks.
Anyone with an active infection or a knee arthroscopy within the last 6 months. Caution with bleeding disorders or blood thinners.
A post-injection flare (joint pain or swelling) occurs in up to about 11% of patients and usually settles within a couple of days.
You will be prescribed antibiotics to take 1 to 6 hours before the injection. Tell future surgical or dental providers you have a permanent hydrogel implant.

Much of Claire’s passion for, and interest in, the field of physiotherapy and rehabilitation came from her own personal journey as an athlete in sport. She played soccer at a high level throughout her junior high and high school years and then went on to play CIS university level soccer as well. During those years she was inspired by the difference that a number of physiotherapists and athletic therapists made in her own life, both personally and from a rehabilitation perspective, and this encouraged her to ultimately pursue her own career in Physiotherapy.  

 

Claire is passionate about partnering with and motivating people to reach their highest potential, regardless of age, current activity level or ability. She wants to empower you to move better and feel stronger in your every day life and help you achieve your goals; whether that be returning to play as an athlete or someone looking to get back to their activities of daily living. Claire likes to incorporate education, manual therapy techniques and strength and conditioning principles into her practice in order to treat a variety of different injuries and conditions. 

 

In her free time, Claire can be found spending time with her family and friends. She loves the outdoors and specifically enjoys road biking, running and walking her dog.
