What this trial is about
The genicular artery embolization vs nerve ablation intervention (GENI) knee OA study is a three-arm randomized controlled trial to evaluate symptoms of knee osteoarthritis (OA) in patients after receiving one of three interventions: sham procedure, geniculate artery embolization (GAE) or genicular nerve phenol nerve ablation (PNA). The main question\[s\] the study aims to answer are: * Does GAE or genicular nerve PNA result in OA symptom alleviation compared to sham procedure? * Are there molecular or imaging biomarkers that aid in predicting treatment response for GAE or genicular nerve PNA? Subjects (N=150) patients with knee OA, resistant to non-surgical treatment for at least 3 months will be randomized 1:1:1 to either after GAE, genicular nerve PNA or sham procedure. Clinical outcomes will be measured using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and 11-point numerical rating scale (NRS) for pain completed at baseline, 1 month, 3 months, and 6 months and then every 6 months for either two years or until the time of total knee arthroplasty (TKA) surgery.
