What’s wrong with fluid in the knee_How can fluid in the knee be eliminated Knee fluid is a common clinical condition that many of you will have. Different people react differently to knee fluid, some will feel pain, swelling or discomfort in the knee, while others may not feel any discomfort either. So should knee effusion matter or not? Is knee fluid normal? There is also fluid in normal joints, but it is a normal synovial fluid, produced by synovial secretion, and is generally maintained in a state where it is not too much or too little. Normal joint fluid is yellowish or colorless, clear and transparent, and has a high viscosity. Synovial fluid plays a role in lubricating joints and nourishing cartilage. When synovial fluid secretion is insufficient, it can lead to problems such as insufficient joint lubrication and wear and tear of joint cartilage. When the synovial membrane is irritated, such as in the case of synovitis, it can lead to excessive secretion of synovial fluid, which, if not absorbed and metabolized in time, can cause this synovial fluid to collect in the joint, causing the pressure in the joint cavity to rise, resulting in swelling and limited movement of the joint. In addition, there are many sensory nerves in the joint cavity, and too much fluid accumulation can also compress these sensory nerves and cause painful sensations. At the same time, a continuous increase in pressure in the joint cavity can cause a series of problems, creating a vicious cycle. What diseases can cause joint effusion? It should be noted that joint effusion is not a specific disease, but a symptom. Many diseases of the knee joint can cause joint effusion. For example, intra-articular free body, meniscal injury, knee cruciate or collateral ligament injury, patellar strain, knee osteoarthritis, tuberculosis infection, septic infection, rheumatism, rheumatoid arthritis, all of these diseases can irritate the synovial membrane of the joint, leading to knee synovitis and causing joint effusion. How is joint effusion treated? Puncture therapy: When joint effusion is large and under high tension, joint puncture can be performed to completely remove the effusion and blood and inject sodium vitrate solution, which is the main component of joint synovial fluid, into the joint cavity. Immobilization and rehabilitation: In the early stage, bed rest should be given, the affected limb should be elevated, compression bandages can be applied, and weight bearing is prohibited. During the treatment period, the quadriceps muscle can be flexed and contracted, and later the knee flexion and extension exercises should be strengthened, which has a positive effect on eliminating joint effusion, preventing quadriceps muscle atrophy, preventing recurrent synovitis, and restoring knee extension and flexion functions. Local closure therapy: closure therapy, also called “local closure”, is a method of treating pain that has evolved from local anesthesia. The basic operation of closure therapy is to inject a mixture of local anesthetic and hormonal drugs into the painful area to achieve the purpose of anti-inflammation and analgesia. Sequestration therapy is a simple, safe, efficacious and reliable treatment method to relieve pain or discomfort in patients with osteophytes. Exercise therapy: Patients should get into the habit of exercising, but they should be careful not to overdo it. Because the knee is the most weight-bearing joint in the body, overload is prone to arthritis. Once the disease has developed, exercise should not be stopped completely, as long as the amount of exercise is adjusted according to the situation, in fact, a certain amount of exercise is still very beneficial for knee osteoarthritis. Medication: In the acute stage of synovial injury, stagnation of blood and stagnation, the treatment is to disperse stasis and produce new swelling, if there is inflammation, anti-inflammatory treatment is needed at the same time.
