About this study
Official title: Creation Of a Prospective Registry For Genicular Artery Embolization At The Joint & Vascular Institute
The goal of this observational study (prospective registry) is to collect long-term real-world data on the effectiveness and safety of genicular artery embolization (GAE) for knee osteoarthritis in adults aged 18 years or older with symptomatic KOA that has not responded to medical therapy.
The main questions it aims to answer are:
Read more
- Does GAE lead to sustained improvement in pain (WOMAC, VAS) and quality-of-life scores over 12-36 months?
- What patient or procedural factors are associated with better outcomes after GAE?
Participants will:
- Undergo GAE as part of their routine clinical care.
- Complete clinical follow-up assessments at 1, 3, 6, 12, 18, 24, and 36 months after treatment, including symptom and quality-of-life questionnaires.
- Have safety outcomes tracked according to Society of Interventional Radiology guidelines.
There is no comparison group; results will be analyzed to identify predictors of success and inform best practices for patient selection and treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Genicular Artery EmbolizationProcedure or surgery
Genicular Artery Embolization (GAE) is a minimally invasive, image-guided procedure in which embolic agents are delivered into hyperemic genicular arteries to reduce synovial inflammation and knee pain from osteoarthritis.
What is being measured
The primary outcome is the main question the study is designed to answer.
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
The investigators will describe differences in pain response with Genicular Artery Embolization (GAE) compared to a sham procedure when treating medically refractory mild to moderate Knee Osteoarthritis (KOA) at 12 months as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain subscale score. A higher score index a higher pain level while a lower score indicates lower pain levels. The score range is 0 to 96.
Measured: 5 years of enrollment/patient
