Genicular artery embolization for the treatment of knee pain secondary to mild to severe knee osteoarthritis : One year clinical outcomes
Copyright © 2024 Elsevier B.V. All rights reserved..
OBJECTIVE: To evaluate the safety and efficacy of genicular artery embolization (GAE) in patients with mild-to-severe knee osteoarthritis up to 12 months after GAE.
MATERIALS & METHODS: This prospective single-center study included patients who had knee osteoarthritis for >1 year with moderate-to-severe pain after failed conservative treatment for >6 months. Baseline imaging features were evaluated to determine Kellgren-Lawrence (KL) grade and magnetic resonance imaging (MOAKS) scores. GAE was performed using 150-350 μm embolic polyvinyl alcohol particles. The visual analog scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were used to evaluate knee pain, stiffness, and function at baseline and follow-up. The primary endpoints were changes in VAS and WOMAC scores at 12 months.
RESULTS: Thirty-three patients (n = 37 knees) aged 66.6 ± 8.7 years were enrolled. The patients were categorized into two groups: mild-to-moderate osteoarthritis (n = 28, KL grades 2-3) and severe osteoarthritis (n = 9, KL grade 4). GAE was successfully performed in all patients, with no major adverse events. Three to six branches of the genicular artery were embolized. The mean VAS and WOMAC scores in the mild-to-moderate group significantly decreased (6.6 at baseline vs. 3.0 at 12 months and 49.4 vs. 27.4, respectively, all P < 0.001). The mean VAS and WOMAC scores in the severe group significantly decreased at 12 months (7.3 vs. 4.4 and 58.1 vs. 40.6, respectively, all P < 0.001).
CONCLUSION: GAE is a well-tolerated and effective treatment that significantly improves pain symptoms and function in patients with mild-to-severe knee osteoarthritis.
