What is Water on the Knee?

by Crystal (SU)
Fluid is an important part of the knee’s design. Bending and rotation of the knee would be difficult without the natural fluid inside the joint. However, knee effusion, commonly known as water on the knee, is abnormal. It happens when excess fluid collects within the knee joint. There are various reasons that fluid builds up in the knee, which can result in a painful and debilitating state. All of the available treatments include removing the unnatural fluid, often in conjunction with medication.
