The author has treated 13 cases of osteoarthritis of the knee joint with a combination of Chinese and Western medicine in the past six months with remarkable results, which are reported below. General information In this group of 13 cases, there were 2 males and 11 females; 3 cases in the right knee and 10 cases in both knees; age ranged from 51 to 74 years old, with an average of 61 years old. All cases presented with difficulty in squatting, pain, swelling, stiffness and joint deformation. All were diagnosed by x-ray plain film. Treatment Chinese medicine: acupuncture and tui-na were the main methods, supplemented by hot compresses with Chinese medicine. Acupuncture points: He Ding, Inner Knee Eye, Outer Knee Eye, Foot San Li, Yinlingquan, Yanglingquan, and A-Yi points. The needle is sterilized and then stabbed directly or obliquely. The treatment time is 30 minutes, once a day, 5 days of treatment and 2 days of rest. Tui-na manipulation: One-finger meditation and plucking method are the main techniques, supplemented by pointing, pressing, kneading, holding, rubbing, shaking and other techniques. (1) One-finger meditation pushing method Use the peak of the thumb finger to act on the above points for 1 minute each. (2) Flicking method Mainly applied to the medial and lateral bone gaps of the knee joint to loosen adhesions, about 30~50 times. (3) Pointing, pressing and kneading method applied to the above points, operated to the patient’s comfort. (4) Take method, i.e., take the patella method The operator pinches the gap between the patella and the femoral condyles with five fingers evenly, first pinching hard toward the center and then lifting, at which time the patient has a pleasant feeling, taking 30~50 times. (5) Rubbing method Make the patient bend the knee, the palm root of both hands apply force to the inner and outer sides of the affected knee, rub upward and downward 10~20 times each, to the extent of heat. (6) Shaking method The operator holds the ankle of the affected limb with one hand, taps the patellar surface with the palm of the other hand and shakes the knee joint 10 times clockwise and counterclockwise, and flexes and extends the knee joint 10 times each. The above techniques (5) and (6) are not limited in order. Western medical treatment: Intra-articular injection of sodium vitrate was mainly used. The patient is placed in a supine position with the knee flexed, strict skin disinfection is performed, a cavity towel is laid, local anesthesia is applied to the knee eye, and a 10 ml needle is used to probe the joint cavity (note that the needle tip is tilted medially to avoid injury to the articular cartilage, and the joint is pumped back after a feeling of emptying), and if there is an accumulation of fluid in the joint cavity, the fluid should be pumped out first; if the fluid is cloudy, the joint cavity can be cleaned with saline, and then sodium vitrate is injected slowly. After injection, the operator should gently shake and flex and extend the affected knee several times so that the fluid is evenly distributed in the joint cavity, especially on the cartilage surface. The patient was instructed to use an elastic knee brace. Inject 2ml each time, once in 7 days, 5 times as a course of treatment Effectiveness: Cure: swelling and pain of the knee joint disappeared, no obstacle to joint movement. Effective: The swelling and pain of the knee joint are significantly reduced, and the joint movement is mildly restricted. Effective: Knee swelling and pain are reduced, joint movement is still limited. Ineffective: No improvement in symptoms and signs before and after treatment, and joint movement was impaired. The cases in this group were treated for 3~5 weeks, with an average of 18 days of treatment. Treatment results: 6 cases (46.1%) were cured, 5 cases (38.5%) were effective, 2 cases (15.4%) were effective, and the total effective rate was 100%. The primary osteoarthritis is closely related to age, mostly seen in people over 50 years old; the secondary osteoarthritis is caused by trauma, deformity, and joint disease, resulting in premature and severe degenerative changes in the knee joint. Its onset is due to lesions in the articular cartilage itself. Sodium vitrate is the main component of synovial fluid and is one of the components of the cartilage matrix. It plays a lubricating role in the joint cavity, reduces friction between tissues, and plays an elastic role, buffering the effect of stress on joint cartilage, significantly improving the inflammatory reflection of synovial tissue, enhancing the viscosity and lubricating function of synovial fluid, protecting joint cartilage, promoting the healing and regeneration of joint cartilage, relieving pain, and increasing joint mobility. In Chinese medicine, this disease is classified as “paralysis”, which is caused by wind, cold, dampness, stasis, deficiency, strain, and other factors that lead to irregularities in meridians and blood. Acupuncture of Yanglingquan can strengthen the tendons and bones; the foot three li is a Yangming meridian point, which is an important point to strengthen the whole body and can regulate the meridian qi of all the yang in the body; the crane top point is a strange point outside the meridian, which can open the meridians and disperse local stagnant qi and blood. By applying external force to specific areas and points on the body surface, manual therapy can promote local blood and lymphatic circulation, improve local tissue metabolism, smooth tendons and veins, increase the pain threshold of local tissues, smooth the flow of qi and blood, and achieve the effect of relaxing tendons and activating channels, reducing swelling and relieving pain. For joint adhesions and stiffness, manipulation can relax the tense muscles, loosen the adhesions, slip the joints, and enhance muscle extension. By moving the knee joint, the displaced and embedded cartilage plate can be retracted, which can release the interlocking of the joint and reduce pain.
