How do you drain the fluid from a knee that was caused by falling?

If you have fluid in your knee caused by a fall, it is important to see a doctor to get a proper diagnosis and treatment plan. Depending on the severity of the injury, your doctor may recommend draining the fluid from your knee. This can be done through a procedure called arthrocentesis, which involves inserting a needle into the knee and withdrawing the fluid. The procedure is usually done in a doctor's office or clinic and takes about 10-15 minutes. After the procedure, you may need to wear a bandage or brace to support your knee and reduce swelling. Your doctor will also provide specific instructions on how to care for your knee and prevent further injury.
