Nonsurgical Knee Procedure Provides Lasting Pain Relief for 80% of Osteoarthritis Patients .

Could blocking abnormal blood vessels offer an alternative to knee replacement? A clinical investigation involving 194 patients with knee osteoarthritis found that 80% experienced meaningful pain relief lasting at least 1 year following genicular artery embolization. The minimally invasive procedure targets abnormal blood vessels associated with inflammation and pain without requiring permanent implants. These findings suggest a potential treatment option for patients with persistent symptoms who wish to delay surgery. However, controlled trials are needed to determine comparative effectiveness, durability and optimal patient selection.
