The Efficacy of Transcutaneous Pulsed Radiofrequency Acupuncture for Knee Osteoarthritis

With the aging population, knee osteoarthritis (KOA) has become a major issue affecting functional living and causing socioeconomic burdens. Its etiology includes biomechanical abnormalities, genetics, hormones, and environmental factors. KOA causes pain, stiffness, and muscle weakness, affecting daily activities and quality of life. Previous studies have shown that traditional acupuncture or electroacupuncture can improve pain and function in knee osteoarthritis. In recent years, pulsed radiofrequency therapy has gradually been applied for pain control in KOA. However, both treatments are invasive, and patients may fear and avoid needle insertion, which also has a higher risk of complications. This study aims to combine the strengths of both treatments by using transcutaneous pulsed radiofrequency(TCPRF) at acupuncture points. This non-invasive treatment approach aims to achieve effective pain control, allowing patients to participate more actively in rehabilitation therapy.
