About

Osteoarthritis (OA) is a highly prevalent degenerative joint disease that contributes to chronic pain and disability in approximately 10% of people over the age of 55. With 25% of Canadians expected to be aged 55 or older by 2036, an increasing number of Canadians will be impacted by knee OA. In affected individuals the risk of medical co-morbidities is increased which can lead to adverse cardiovascular outcomes, depression, and poorer quality of life. Current conservative therapy includes oral analgesia, lifestyle modification, corticosteroid injection, and viscosupplementation. These current conservative measures have variable responses. In patients who would prefer to avoid surgery or are not surgical candidates safe and consistently effective treatment options are lacking.

Geniculate artery embolization (GAE) is a minimally invasive alternative with low risk of complications that has shown promise in exploratory studies. GAE provides benefit by disrupting angiogenesis in the knee which can contribute to chronic inflammation of the affected joint, and helps prevent the growth of new sensory nerve fibers which can reduce the pain associated with osteoarthritis.
