Artery Embolization Relieves Knee OA Pain for Up to 3 Years

Transcatheter genicular artery embolization provided durable pain reduction in patients with moderate-to-severe knee osteoarthritis: mean pain scores dropped from 8.1 to 2.5 at 36 months and WOMAC scores improved markedly (exact figure not reported in source).

• Single-arm, multi-center study following patients after genicular artery embolization; exact sample size not reported in source.
• This minimally invasive IR procedure targets abnormal neovascularity in the joint capsule.
• Limitations include lack of a control/sham arm and unclear blinding; external validation pending.
