Pharmacopuncture Therapy for Chronic Knee Pain

This study is a pragmatic randomized controlled trial. Condition/disease: Chronic Knee Pain. Intervention: Pharmacopuncture

Knee pain can have various causes. It may result from tears and injuries to structures or from inflammation due to various diseases. Chronic pain is often caused by overuse injuries, inflammation, or arthritis. Among these, osteoarthritis (OA) is the most common cause of chronic pain, affecting approximately 10% of Korean adults aged 20 to 89, either currently or in the past. In addition to OA, other conditions such as rheumatoid arthritis, post-traumatic degenerative arthritis, and chondromalacia can also lead to chronic pain. Therefore, it is evident that a significant number of patients suffer from chronic knee pain.

The purpose of this study is to conduct a pragmatic randomized controlled clinical trial involving 40 patients suffering from chronic knee pain. The trial will compare the effects of treatment strategies utilizing pharmacopuncture (20 patients) with those utilizing the standard Western medical treatment of physical therapy (20 patients) to verify the comparative efficacy of pharmacopuncture.

However, in this pragmatic clinical trial, patients will be randomly assigned to either the pharmacopuncture strategy or the physical therapy strategy. The specific methods of physical therapy and pharmacopuncture will not be predetermined but will be administered based on the clinical judgment of physicians and traditional Korean medicine practitioners according to the patient's condition. All applied treatment methods will be retrospectively reviewed through chart review and recorded in the Case Report Form (CRF) for comparison.
