This is a single-center, pilot study to assess the feasibility of a study show the effectiveness of the genicular artery embolization (GAE) in reducing arthritic pain and dysfunction associated with mild to moderate Bilateral or unilateral osteoarthritis of the knee. Patients with bilateral or unilateral Grade 1-3 Osteoarthritis as diagnosed on standing weight-bearing knee radiographs per the Kellen-Lawrence Grading scale, will be offered enrollment to the study. Following a screening questionnaire, these patients will then be enrolled in this study. Baseline MRI will be obtained prior to the GAE procedure. Follow up intervals will include 3, 6, 9, and 12 months with the primary objective measured by a clinician as the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, Knee Injury and Osteoarthritis Outcome (KOOS) score, and Oswestry Disability Index at the 12-month follow up visit. Patients will also undergo 1 year follow up MRI to be interpreted by a diagnostic radiologist with subspecialty training in musculoskeletal radiology. This radiologist will compare the treated knee to the baseline screening according to the WORMS classification (Whole Organ Magnetic Resonance Scoring) to assess for radiologic changes of osteoarthritis and any adverse effects.
The goal of this study is to perform a feasibility study to show the effectiveness of the genicular artery embolization procedure in reducing bilateral or unilateral osteoarthritic knee pain at 12 months as measured by WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, Knee Injury and Osteoarthritis Outcome (KOOS) score, and Oswestry Disability Index.
