Knee osteoarthritis develops gradually as joint cartilage wears down, often resulting in pain, stiffness, swelling, and reduced mobility. This article discusses Genicular Artery Embolization (GAE), a minimally invasive procedure used in selected patients to help manage persistent knee pain. It explains patient evaluation, imaging guidance, treatment planning, recovery expectations, follow-up recommendations, and current clinical considerations.
