Genicular nerve radiofrequency ablation is a minimally invasive treatment for knee pain due to osteoarthritis. Recent research to be presented at the Society of Interventional Radiology Annual Scientific Meeting in Phoenix suggests that this treatment can significantly reduce pain, especially for adults who are 50 and older.
Interventional radiologists perform genicular nerve radiofrequency ablation by image guidance to place probe needles next to the nerves of the knee that can send pain signals to the brain. The probes generate radio waves, creating a ball of heat to dull or destroy the pain nerve endings. These nerves do not control muscles or affect balance, making the procedure safe. Furthermore, patients leave with Band-Aids, not stitches.
Before treatment, patients had a mean baseline VAS of 8.58 and a mean baseline WOMAC of 66.6. After treatment, all study participants experienced a statistically significant reduction in pain. The mean VAS of 8.58 decreased to 5.02, while the mean WOMAC score decreased from 66.6 to 41. The greatest increase in functionality and decrease in pain was recorded for patients 50 and older compared to younger participants.
