As our nation ages, more and more people are dealing with severe knee pain \u2014 even after therapy, medications, and injections. The good new is, there\u2019s a new solution for those of us who are too young, too old, or too ill for knee replacement surgery: radiofrequency ablation.\n\u201cIt\u2019s a new application of a tried and proven technique,\u201d says Zongfu Chen, MD, medical director of UPMC Pain Medicine at UPMC East. \u201cWe are using radio waves to disrupt and cut off the nerve signal from the knee.\u201d\nAccording to Dr. Chen, radiofrequency ablation has been used for nearly three decades to relieve back and neck problems. Now, doctors are using radio waves to generate heat directed at three of five branches of nerves that start at the knee. Relief can be felt almost immediately and can last up to a year.\nDr. Chen, an anesthesiologist and pain management specialist, says the procedure is done in two steps. The first step involves temporarily blocking the nerves in order to see if your knee pain goes away. If so, you can proceed to the second step \u2014 radiofrequency ablation.\nThis minimally invasive procedure takes about 30 minutes and is performed with local anesthesia and, sometimes, light sedation. No surgical tools are needed \u2014 just three special needles used to heat and deactivate the nerves. Patients can resume normal activities the next day.\nDr. Chen says patients may feel discomfort again when the nerves begin to regenerate. The radiofrequency ablation procedure can be repeated, if needed.\nBenefits of Using Radio Waves to Treat Knee Pain\n\nMinimally invasive outpatient procedure\nPain relief lasts 9 to 12 months\nNo incision\nNo down time\nCan be repeated multiple times\n\nRisks of Using Radio Waves to Treat Knee Pain\n\nLocalized aching\nTemporary weakness\nSmall chance of infection\nSome patients feel no relief\n\nTo find out if you\u2019re a candidate for radiofrequency ablation for knee pain, contact your orthopaedic specialist or primary care physician.
