Recently, I’ve been hearing a lot of complaints from patients in the outpatient clinic: “Doctor, I’ve been having a lot of pain in both knees lately, what should I do? The patient is walking with a limp, and it’s hard to go up the stairs. Both knees are swollen like a pig’s foot. I had to go to the hospital. The doctor looked at it, took a film and diagnosed it as “osteoarthritis of the knee”. What should I do next? The patient asked. Osteoarthritis, also known as degenerative joint disease and hypertrophic osteoarthritis, is a chronic, multi-level, aseptic inflammatory disease that involves bone, bursa, joint capsule and other structures of the joint, with joint pain and degenerative changes as the core. It is more common in middle-aged and elderly people, more women than men, with a prevalence of up to 50% over the age of 60 and up to 80% at the age of 75, and a disability rate of up to 53%, which may lead to a shorter life expectancy. Its clinical manifestations include: joint pain Initially, it is mild to moderate intermittent vague pain, which improves at rest and is often related to weather changes. In the late stage, there may be persistent pain or nocturnal pain, localized pressure pain, especially when swelling; joint stiffness stiffness and tightness when waking up in the morning, relieved by activity, lasting for a short time, often a few minutes to ten minutes, rarely more than 30 minutes; joint enlargement Some knee joints due to the formation of bone superfluous or joint effusion; bone friction sound due to the destruction of joint cartilage, joint surface unevenness, bone friction sound when the joint activity The joint may become weak when walking, or the leg may not be fully straightened or the movement may be impaired; X-ray shows asymmetric joint gap narrowing, subchondral bone sclerosis and/or cystic changes, joint edge hyperplasia and bone redundancy or joint effusion of different degrees, and some joints may have free bodies or joint deformation. How do we treat osteoarthritis of the knee? First, medication is the foundation. For any pain, pain relief is the first priority. We will give some anti-inflammatory and pain medication to the patient. This will reduce the sterile inflammation in the joint and reduce the pain. We also give drugs such as “aminoglucose and chondroitin sulfate”, which enhance the metabolism of the cartilage and improve its function, and are suitable for long-term use. We also do some herbal fumigation of the knee, silver needle, small needle release, ozone injection, etc. in the muscle strain points around the knee joint to improve the muscle elasticity, strengthen the muscle toughness and reduce the burden on the joint. For intra-articular injections, we believe that closure, or hormone injections into the joint, are indeed fast and cheap, but they tend to aggravate joint degeneration and osteoporosis. Therefore, for patients with joint swelling and effusion, especially purulent effusion, we first inject medical ozone into the joint cavity in stages, which can play a very good anti-inflammatory and pain-relieving role without the side effects of hormones. Sodium hyaluronate can change the rheological state of the joint fluid in the joint cavity, increase the lubrication of the joint, protect the joint cartilage, blunt the sensitivity of the receptors to stimulation, reduce pain, induce the production of endogenous sodium hyaluronate, and achieve the effect of inhibiting the further development of the disease. Then how do we pay attention to protect the valuable knee joint 1, pay attention to warmth 2, action support: mainly to reduce the weight of the affected joint, cane, crutches, walkers, etc., to change the negative gravity angle line, according to the deformity, the corresponding orthopedic brace or orthopedic shoes; 3, functional training: such as knee flexion and extension activities in the non-weight-bearing position to maintain maximum joint mobility; 4, aerobic exercise: such as swimming, bicycling, etc.; 5, weight loss: obesity, the knee joint in the non-weight-bearing position, to maintain maximum joint mobility; 4, aerobic exercise: such as swimming, bicycling, etc. 5, weight loss: obesity can induce the occurrence of knee osteoarthritis through the intermediate products of the metabolic process; 6, self-protection: do not often squat or kneel down to get things, sit on a low stool, sleep on a low bed, increasing the friction and weight of the joint 7, reduce unreasonable exercise, such as knee osteoarthritis patients like to play Tai Chi (repeated squatting), climbing and other exercises to exercise the joint, which will only increase the joint torque or make the joint surface load Through the joint efforts of doctors and patients, it is not an extravagant hope to relieve the pain of the knee joint.
