Closing the treatment gap in knee osteoarthritis — the GEKO trial begins

Knee osteoarthritis is one of the most common musculoskeletal conditions, affecting almost one in five people over the age of 45 in the UK — around 4 million people. For many, it means living with chronic pain, limited mobility, and a gradual decline in quality of life. At its most severe, the only effective option is knee replacement surgery.
But what about those who aren’t yet at that stage? Despite trying physiotherapy, anti-inflammatories, and combinations of painkillers, many patients remain stuck in a treatment gap. Their pain is poorly controlled, yet surgery is not an option.
A new approach — genicular artery embolisation (GAE) — might offer hope. The procedure blocks small blood vessels around the knee that are thought to drive inflammation and pain. Early studies have hinted at benefit, but the evidence so far is mixed: one small trial showed no improvement, while another found a modest reduction in pain. Despite this uncertainty, the technique is already being used internationally.
