Radio Waves That Warm Up Nerves Are a New Knee Surgery Alternative
Another relatively new alternative to knee replacement surgery is cooled radiofrequency ablation. The procedure involves using an electrode to first heat up the nerves around the knee joint and then cool them down. This process, known as cooled radiofrequency ablation, interferes with the nerves’ ability to send pain signals to the brain. The treatment was approved to treat knee pain in 2017 and is not as well studied as other knee pain treatments.
However, one study found that around three-quarters of people who received the treatment reported significant improvements in symptoms six months later. A more recent study found similar results in 80 percent of patients after a year. The procedure is outpatient and minimally invasive but can be quite expensive.
