TCM external treatment for knee osteoarthritis

According to traditional Chinese medicine, knee osteoarthritis is closely related to the deficiencies of liver and kidney, malnutrition of bones and muscles, the attack of wind-cold-damp pathogen and phlegm and blood stasis. It is asthenia in origin and asthenia in supelficiality. TCM for external use can strengthen tendons and bones, promote blood circulation to remove meridian obstruction and dispel wind and eliminate dampness. Studies have shown that TCM for external use can im- prove local blood circulation, reduce intraosseous pressure, increase SOD activity and protect the articular cartilage. These treatment methods such as washing, fumigation, hot compress, ironing and iontophoresis have good effect on KOA.
