Knee osteoarthritis is commonly referred to as osteoarthritis of the knee, which is a degenerative osteoarthropathy. The treatment plan for knee osteoarthritis is currently based on a stepwise approach that includes health education, aerobic exercise, mobility support, medication, joint injections, arthroscopic surgery, osteotomy, and prosthetic arthroplasty. The first step is based on the patient’s physical condition and the severity of the osteoarthritis, and for early stage knee osteoarthritis patients, conservative treatment is an option. Patients with knee osteoarthritis must take more rest during the acute phase, as too much activity or too much strain can aggravate the symptoms. Since osteoarthritis is more common in middle-aged and elderly patients, Chinese medicine believes that it is related to the decline in the function of the liver, spleen and kidneys, and that cold factors tend to aggravate local symptoms. It may be useful to reduce the decomposition of articular cartilage, promote the synthesis of cartilage, and inhibit the inflammatory response. You can also do some appropriate exercises and lower your weight with the help of your healthcare provider, and use the correct auxiliary support. In patients with severe symptoms and significant pain, medications can be used such as non-steroidal anti-inflammatory drugs under the guidance of a physician, and hyaluronic acid injections in the knee cavity can also be considered to reduce pain through a variety of mechanisms such as nourishing cartilage. Arthroscopic treatment is also an option for cases that meet the indications, but while arthroscopic surgery allows for knee cleanup and shaping, it is limited in the treatment of simple osteoarthritis and the indications must be chosen with caution, especially for older patients with simple osteoarthritis. In addition, patients with combined osteoporosis should also focus on the treatment of osteoporosis at the same time. If more severe pain and joint deformation occurs in the knee later in life, total knee replacement surgery can be performed if conditions permit.
