A minimally invasive knee arthritis procedure using dissolvable particles eased pain and improved mobility in a study of 194 patients, with benefits lasting at least 12 months.
01Summary
- 01Researchers studied genicular artery embolisation in 194 patients with osteoarthritis-related knee pain.
- 02The treatment uses a thin catheter and tiny gelatin-based microspheres that dissolve within hours to block abnormal blood vessels.
- 03At the one-year follow-up, 80% of patients assessed reported clinically meaningful pain relief.
- 04The procedures took place between July and November 2024, and all 239 procedures were technically successful.
- 05Forty-five participants, or 23%, had arthritis in both knees and received two separate treatments within four weeks.
02Why it matters
The findings suggest a possible option for people whose knee arthritis pain has not improved with physical therapy, medicines or injections, but who cannot or do not want knee replacement surgery. If confirmed, it could widen access to treatment and reduce the need for major operations.
