Sequential Genicular Nerve Ablation Prior to Geniculate Artery Embolization in Knee Pain

Participants in the experimental arm will undergo genicular nerve ablation (GNA), a minimally invasive procedure targeting the genicular nerves to interrupt pain transmission. One month after undergoing GNA, participants will receive geniculate artery embolization (GAE), which targets the geniculate arteries to reduce inflammation and pain.

Participants in the active comparator arm will receive geniculate artery embolization (GAE) alone, a minimally invasive procedure targeting the geniculate arteries to reduce inflammation and pain, without prior genicular nerve ablation (GNA).
