What are the early symptoms of arthritis in the knee? Arthritis is a common and frequent disease, and many people have symptoms of arthritis in the knee, but some patients do not have serious symptoms and ignore the disease. Although many people are aware of arthritis, some patients do not have a good understanding of the disease and therefore ignore it. Let’s take a look at the symptoms and causes of arthritis in the knee, in the hope of enhancing your understanding of the disease. The symptoms of arthritis of the knee Early symptoms of arthritis of the knee 1, joint pain and soreness, often triggered by minor sprains, cold and after exertion 2, often when going up and down the stairs, leg weakness 3, morning after waking up with joint stiffness, but not more than 5 minutes, pain and stiffness slightly suitable activities can disappear, pain and weather changes, air humidity increases when sensitive 4, joint swelling and pain and functional limitations for episodic, 1 year – 2 years 1 attack, short duration, no symptoms when not attacked. Symptoms of mid-term knee arthritis 1. joint pain episodes are often without obvious triggers 2. inability to walk up and down stairs and long distances freely 3. start to have night rest pain, joint stiffness for 10 minutes-15 minutes after waking up in the morning, joint pain is clearly related to weather changes 4.The number of pain episodes increases, the symptoms progressively worsen, more than 2 episodes in 1 year, the duration is prolonged compared with the early period, and the time without episodes is shortened. Symptoms of severe knee arthritis: severe deformation of the joint, “O” and “X” shaped legs, severe pain, and difficulty walking. The joint gap is gone on imaging, i.e., there is no gap in the joint, and the joint is full of bone spurs, so walking a few hundred meters is painful. Knee arthritis factors 1, age factors Knee joint in the human body is heavily burdened, with the age of the knee capsule atrophy, degeneration and fibrosis, the joint becomes stiff and inflexible, synovial fluid secretion is abnormal, causing insufficient nutrition of cartilage cells, the content of water in the cartilage decreases, the main component of cartilage mucopolysaccharide is also reduced, the articular cartilage lacks elasticity, it is susceptible to wear and tear and broken. In order to adapt to the needs of the knee joint bearing force, the edge of the articular cartilage has osteophytes, that is, the occurrence of osteoarthritis in the elderly. 2, endocrine factors Endocrine disease patients, the knee joint long-term minor trauma, excessive inappropriate exercise, etc., are caused by the knee joint load, conduction disorders, causing degenerative changes in the knee joint cartilage, secondary to osteoarthritis of the knee. 3, obesity factors This disease is related to weight overload, menopausal women weight gain can contribute to the occurrence of osteoarthritis. 4.Trauma Fracture, dislocation, meniscal or ligament injury in the knee joint can cause instability of the knee joint, which is the cause of secondary osteoarthritis of the knee joint. 5, Inflammation Knee septic arthritis and tuberculosis, rheumatoid arthritis, etc., even if the inflammation subsides, the cartilage surface of the joint is damaged to varying degrees, such as the joint still maintains a considerable degree of mobility, most secondary to osteoarthritis. 6, joint anomalies inversion and valgus deformity of the knee joint, large joint disease, multiple epiphyseal dysplasia, etc. can be secondary to this disease. Through the above article, I believe you have a better understanding of knee arthritis, and I hope you can pay more attention to this disease. It is important to discover the existence of the disease and treat it in time, because arthritis is not only harmful to the body, but also difficult to treat.
