Arthrosamid® Injection for Knee Osteoarthritis
There is a new injection product available that can potentially help some people with chronic knee pain due to osteoarthritis. This is called Arthrosamid, and it is a polyacrylamide hydrogel that acts as a permanent implant within the knee joint. After injection, the hydrogel integrates with the synovial lining of the knee and is designed to provide long-lasting pain relief and improve function in people with knee osteoarthritis.
This treatment is private pay, as it is not currently covered by provincial health plans or most private insurance plans. The cost of the treatment is $4,000.
A full assessment is completed before the injection is provided to determine whether a patient is a suitable candidate. This includes a detailed history and physical examination, review of relevant imaging, and a discussion around the potential benefits, risks, limitations, and available alternatives. Not everyone with knee osteoarthritis will be an appropriate candidate for this treatment, and results cannot be guaranteed.
What Does the Procedure Involve?
Arthrosamid is provided as a single injection directly into the knee joint using ultrasound guidance to ensure accurate placement. Antibiotics are taken before the procedure to reduce the risk of infection, and a local anesthetic is used to make the injection more comfortable. The procedure is performed using sterile technique and generally takes only a short period of time.
After the injection, patients are provided with specific post-procedure instructions. Some temporary discomfort, swelling, or stiffness can occur following the injection. Patients are generally advised to limit strenuous activity initially and then gradually return to their usual activities as tolerated. Improvement is not necessarily immediate and may develop gradually over the weeks following treatment.
