Osteoarthritis (OA) is a chronic degenerative disorder of the joints, characterized by disruption and, later, a complete loss of joint cartilage, associated with bone hypertrophy leading to reduction of joint space and osteophyte formation. This causes gradually developing pain and stiffness of the affected joints, mostly on awakening and after rest. Swelling of joints is often present. Joints of the hands, knees, hips, and spine are most commonly affected. OA is the most common form of arthritis, affecting 3.8% of people.1 Above the age of 60, 10% of males and 18% of females are affected.2 Older age, obesity, joint injuries, genetics, and bone deformities are risk factors. Diagnosis is by X-rays and magnetic resonance imaging. Modern biomedicine treatment involves analgesics, nonsteroidal anti-inflammatory drugs, duloxetine, physical therapy, steroid injections, lubrication injections of hyaluronic acid, osteotomy, and joint replacement.
Osteoarthritis in Chinese Medicine
In Chinese Medicine, OA is a form of Bi Syndrome (Painful Obstruction Syndrome) caused by invasion of External Wind, Cold, or Dampness. Genetic factors, sprains, traumas, and overuse are also implicated. These factors produce obstruction to the flow of Qi and Blood in the channels. The condition of internal organs plays an important role in the production of this disease as follows:
• Spleen Deficiency (Damp Painful Obstruction Syndrome)—Swelling of joints, aggravated by dampness and pain fixed in one place are the features.
• Yang Deficiency (Cold Painful Obstruction Syndrome)—This is characterized by severe pain in a joint, usually unilateral, that is aggravated by coldness.
• Blood Deficiency (Wind Painful Obstruction Syndrome)—Pain moving from joint to joint is the classic feature.
• Yin Deficiency (Heat Painful Obstruction Syndrome)—Warm painful joints with redness and swelling characterize this syndrome.
Bone Painful Obstruction Syndrome
Any of the aforementioned pathologic patterns, when becoming chronic, leads to Stagnation of body fluids in and around the joints; the fluid then condenses to form Phlegm. This leads to swelling and deformities of the affected joints. Repeated attacks also produce Stasis of Blood, which causes pain.
Liver is responsible for the movements of Qi, and, in all cases, of Painful Obstruction Syndrome, there is usually a Deficiency of Liver. In addition, the Kidneys control the bones, and hence, in OA, there is usually an underlying Kidney Deficiency.
Treatment
While various patterns are described as above, in chronic cases, usually, there is a mixture of various patterns and, in practice, it is simpler to consider them together as Chronic Painful Obstruction Syndromes with clinical features of all patterns. Treatments are:
• Correct Qi and Blood Deficiency—Reinforce ST 36, SP 6, CV 4, LR 8, BL 20, and BL 23.
• Resolve Phlegm—Reinforce BL 20 and CV 12; stimulate by the even method SP 9, ST 40, SP 6, and CV 9.
• Resolve Stasis of Blood—Reduce SP 10, LI 11, PC 6, and BL 17.
• Correct Deficiencies of the Liver and Kidneys—Reinforce LR 8, GB 34, BL 18, KI 3, GB 39, and BL 23.
Points for commonly affected joints
Points for commonly affected joints are as follows:
• Fingers—Baxie, LI 3, TB 3, SI 3, TB 5, LU 7, and SI 5
• Hips—GB 41, GB 40, BL 62, SP 3, GB 30, GB 29, and SP 12
• Knees—SP 5, GB 40, and ST 41 are the most useful distal points; ST 34 (for pain above the knee); ST 36, GB 34, and GB 33 (for pain on the lateral side); SP 9, LR 7, and LR 8 (for pain on the inner side) are the most useful points. GB 41 and TB 5, in that order, open the Yang Linking Vessel; SP 4 and PC 6, in that order, open the Penetrating Vessel and are most useful for the lateral and medial pain of the knees, respectively, determined by their opening points
• Lower-back pain—Shiqizhuixia (Extra Point on the Governor Channel below the tip of L5); BL 26 and BL 54; Tunzhong (Extra Point lateral to BL 54 halfway between the midline and the edge of the buttock); Yaoyan (Extra Point in the depression lateral to the interspace between the spinous processes of L4 and L5, are the local points; the usual distal points are SI 3 and BL 62, in that order, to open the Governor Vessel; GB 41 and TB 5, in that order, to open the Belt Vessel, which crosses the lower back horizontally; BL 62 and SI 3, in that order, if the pain radiates to the hip to open the Yang Stepping Vessel; BL 60, KI 4, and HT 7 (relieving spasm); GV 20 (for pain in the lower most part of the lumbar spine); and SP 3 if there is spinal deformity.
In chronic cases, reinforce BL 20 and SP 3 to stimulate the Spleen (to affect back muscles); KI 3 and BL 23 to stimulate the Kidney (Kidney controls the bones); BL 11 and GB 39 to stimulate the bones; and LR 8 and BL 18 to stimulate the Liver (to affect the ligaments and cartilage).
Chinese herbal remedies
Treatment of OA with Chinese herbs is complex and is beyond the scope of this Clinical Pearl. However, as a general remedy, Shu Feng Huo Luo Pian has been found to be helpful for relieving symptoms (83%–90%) of OA, with only mild side-effects.3
Auricular points
Auricular points to use are the Parathyroid Gland, Parathyrotropin, Point Zero, Ear Shen Men, Endocrine Point, Adrenal Gland C, Adrenal Gland E, ACTH [adrenocorticotropic hormone], Apex of Ear, Allergy Point, Omega 2, and corresponding body area points. Select according to tenderness.
Evidence for Acupuncture
A review of 12 trials involving 1763 participants, by Manyanga et al. showed significant improvement in pain intensity, functional mobility and quality of life in verum acupuncture–treated patients, compared with sham-acupuncture treated patients, no treatment, or usual care.4
Ten trials involving 1456 participants provided evidence that acupuncture is an effective treatment for pain and physical dysfunction associated with OA of the knee.5
Ten studies demonstrated greater pain reduction in acupuncture groups of patients who had peripheral joint OA, compared with controls with the same condition.6
Illustrative Case
A 76-year-old woman complained of swelling and pain over the medial side of her right knee for more than 5 years. X-rays showed evidence of OA, with reduction of space in the medial compartment and osteophytes. The points used to treat her were:
• The even method was used for SP 4 on the right and PC 6 on the left to open the Penetrating Vessel (the sides would be reversed in men). The descending branch of this vessel runs from ST 30 to the great toe along the medial side of the knee.
• ST 30 was reinforced to promote the flow of Qi along the descending branch of the Penetrating Vessel.
• LR 8 was needled by the even method. This nourishes the Liver to promote the flow of Qi and is also a local point (promotion of Qi needs the reinforcing method, while a local point needs a reduction method, so even the method was used).
• LR 7 was reduced as a local point.
• KI 3 was reinforced to stimulate Kidney Yin (Kidney controls the bones).
• SP 6 was reinforced to stimulate the Spleen to resolve Dampness (swelling).
• SP 9 was stimulated using the even method. This point stimulates the Spleen and is also a local point.
• All tender local points were reduced.
She was treated twice a week for 6 weeks with near-total relief of her symptoms, but considering the chronicity, structural changes in the knee, and her age, she will require ongoing treatments at least at monthly intervals, and sometimes even more frequently.
