What good method is there to remove water from thighs and knees? Tell me about it.

The knee joint is obviously swollen and sore, and even unable to walk. B-ultrasound examination showed a large amount of joint effusion in the knee joint. The patient is puzzled: How can there be water in a good knee joint? It's actually called knee synovitis. 1. What is knee synovitis? It refers to a non-infectious inflammatory reactive disease that causes synovial membrane injury or rupture when the knee joint is subjected to acute trauma or chronic strain, resulting in blood or effusion in the knee joint cavity. It can be divided into acute traumatic synovitis and chronic traumatic synovitis. Acute traumatic synovitis mostly occurs in young people who love sports; Chronic traumatic synovitis mostly occurs in middle-aged and elderly people, obese people or people who have used knee joints to carry loads. Second, the cause of knee synovitis Acute synovitis is mostly caused by shock, torsion and excessive exercise. After surgery, swelling, pain, difficulty in moving, limping 1 ~ 2 hours, local skin temperature is high, skin is swollen and tense, and blood is punctured from joints. This disease is often a complication of other knee joint injuries and should be differentiated from fracture, dislocation, ligament and meniscus injuries. Chronic synovitis is generally caused by the transformation of acute traumatic synovitis, or the exudation of synovitis caused by other chronic strains in the elderly, leading to joint effusion. More common in middle-aged and elderly people, with a history of fatigue or joint pain. Patients feel heavy legs, swollen joints, difficulty squatting, or pain going up and down stairs, which is aggravated after fatigue and cold, and relieved after rest and warmth. For patients with long course of disease, quadriceps femoris muscular atrophy, unstable joints and limited activities, joint puncture can draw out pale yellow and clear effusion. X-ray film shows that there is no obvious abnormality or osteophyte formation in the bone and joint structure of the knee joint, and the joint is swollen and the activity is unfavorable. Treatment of synovitis of knee joint 1. Massage therapy (1) Massage acupoint method: The patient lies on his back, with his knees from top to bottom, and repeatedly massages the tendons and veins 1 ~ 2 minutes. (2) Stretching knees and bending knees: the patient's posture is the same as above, and the muscles are relaxed. The doctor bends and stretches the knee joint back and forth gently and slightly, and finally tries his best to bend the knee joint completely, and then straightens the affected limb. (3) tendon scraping and tendon detachment: the patient lies on his back, and puts his thumb on the flexor joints on the upper and lower sides of the patella and inside the pain point; Press the other palm on the flexed thumb and push it out several times with arm strength. (4) When joint effusion occurs, the methods of beating, rolling and patting can be used alternately. With real boxing, with empty boxing, hit the soft tissue around the patella and the outrigger side of the thigh, flex and stretch the thigh 20 ~ 30 times each, with real boxing, press the same place as the upper part with both fists, and repeat 1 ~ 2 times. Hit the popliteal fossa with your palm instead of boxing, and bounce it with your wrist. 2. Puncture therapy When joint effusion and tension are high, joint puncture can be performed to completely drain the effusion and hematocele, and sodium hyaluronate is injected into the joint cavity. Sodium hyaluronate is the main component of joint synovial fluid. Studies have shown that various pathological changes of arthritis are closely related to its reduction and changes in physical and chemical properties. Injection of sodium hyaluronate has the following effects: covering the surface of articular cartilage can protect articular cartilage and prevent or delay further degeneration; Protecting joint synovium and removing pain-causing substances can obviously relieve pain; Improve joint contracture and increase joint mobility; Can improve synovial fluid of degenerated joints. 3. Drug treatment of acute synovial injury, blood stasis block, the treatment methods are mainly to dissipate blood stasis and detumescence, oral administration of Sanqi, etc. Chronic retention of water and dampness, muscle weakness, the treatment is to dispel wind and dry dampness, strengthen tendons and bones, oral Notopterygium Shi Sheng decoction, external use of dog skin cream; If the cold pathogen is strong, it can also dispel cold, dispel wind and remove dampness, and then decoct with aconite water. 4. In the early stage of fixation and acrobatic treatment, you should stay in bed, raise the affected limb, compress it with elastic bandage, and prohibit negative weight. During the treatment, the quadriceps femoris can be exercised to relax and contract, and the knee flexion and extension exercise should be strengthened in the later stage, which has a positive effect on eliminating joint effusion, preventing quadriceps femoris from muscular atrophy, preventing synovitis from recurring and restoring knee flexion and extension function.
