Will the “long water” of the knee “pump more and more”? Experts refute rumors: no such thing

Changjiang Daily Wuhan Client May 23rd 65-year-old Ms. Wang suffered from synovitis and needed to extract fluid from her knee. She was quite concerned about this: whether she would pump more and more more? The doctor said that “more and more effusion” is a common misunderstanding. As long as you ensure rest and take reasonable medication, you can effectively control the recurrence of effusion.

Recently, when Ms. Wang was busy with housework, she gradually felt that her bilateral knees were a little bit overwhelmed, not only began to hurt, but also swelled. I heard people say that this is due to the accumulation of water in the knees and needs to rely on hot compresses to reduce the swelling. Ms. Wang used hot water to soak her feet and hot towels to compress her knees. Unexpectedly, after a day of tossing, the swelling not only did not subside, but became more serious.

Ms. Wang’s knee was significantly swollen.

On May 17, Ms. Wang went to Wuhan Fourth Hospital for treatment. In the meniscal synovitis clinic of the Department of Sports Medicine of the hospital, the receiving physician Li Yanan, after inquiring about the medical history and physical examination, determined that Ms. Wang had synovitis in both knee joints. Combined with the patient’s joint swelling, she needed to undergo knee puncture and fluid extraction. treat.

As soon as the doctor said that she would “pump” her knee, Ms. Wang felt a drum in her heart again. She told the doctor that she had heard that the fluid in the knee would be pumped more and more, and all that was pumped out was “joint oil”, which would affect the nutrition of the knee.

Li Yanan patiently explained to Ms. Wang that the knee joint effusion will not increase due to the extraction, nor will the joint “dry” after extraction. However, in reality, there are some patients, because they did not rest in time and cooperate with the medicine according to the doctor’s instructions after the fluid was drawn, resulting in repeated effusions, forming the impression of “more and more pumping”. As long as the aseptic operation is strictly performed, the knee joint puncture and extraction can effectively avoid side effects while exerting the therapeutic effect.

After some explanations, Ms. Wang finally dispelled her concerns. Subsequently, the medical staff carefully took out more than 60 ml of fluid from Ms. Wang’s knees. Ms. Wang immediately felt that the swelling and pain were significantly relieved. After the combination of oral and topical drugs in the later period, Ms. Wang’s condition improved rapidly.

Li Yanan introduced that the swelling and effusion of the knee joint are very common in daily life, and most of them are simple synovitis caused by excessive exercise and labor. Use a cold compress instead of a hot compress. For patients with more effusion, severe swelling and pain, or repeated symptoms, knee puncture can quickly relieve symptoms, and it is also a means to assist in judging the condition.
