Draining water from the knee is a medical issue that a doctor must perform. Doing it yourself should never be attempted.
If you meant to ask how excess fluid that accumulates in your knee is drained...a nurse or a doctor drains it using a large syringe.
No. Once you have fluid in your knee you can only have a medical physician drain the fluid. It's not a big deal if you have fluid in your knee unless you are experiencing pain in your knee.
A fluid drain on the knee can be a long recovery. Depending on the physical health of the patient, the fluid drain can take a few months to one year to fully recover from.
Why would you do that?!
The only way that you can tell that if your knee is going to be drained of fluid is by a doctor's opinion. If you feel a lot of fluid in your knees, you need to seek the opinion of your physician.
You don't do it your self. Go to an er room and have a doc do it.
To remove excess fluid on the joint.
Aspiration is the removal of fluid from the body by suction so if something is aspirated fluid is drawn off by suction, for example excess fluid around the knee joint is often removed by inserting a needle into the inter-capsular space and the excess fluid drawn off.
The medical term for the removal of fluid from the knee joint is arthrocentesis or joint aspiration. It is a procedure performed to relieve pain and swelling caused by excess fluid accumulation in the knee joint.

If you have fluid in the knee then you should put a pack of frozen peas on it and then put a hot water bottle on it this is only when you have been to the hospital before you do this or this could make a serious problem.
Likely fluid inside. See a doctor they could and probably would drain it.
