The primary cause of osteoarthritis is degeneration, which can lead to damage, wear, and tear of cartilage within the joints, as well as the formation of excessive osteophytes and bone spurs around the joints. These changes cause symptoms such as knee pain, swelling, and difficulty walking. There are many treatment methods available, the most common of which include oral medication, rest, physical therapy, and moxibustion, all of which can help alleviate symptoms. However, these treatments only provide relief from the symptoms of osteoarthritis and do not cure the condition. If a cure is needed, surgical treatment, such as total knee replacement, may be necessary to fully recover. Conservative treatments like moxibustion can help relieve pain and reduce swelling, but they only offer relief and do not cure the condition. Therefore, while moxibustion can alleviate pain from knee arthritis, it cannot cure it.
