Knee Effusion

Knee effusion is a medical term used to describe a condition in which fluid accumulates in or around the knee joint. It is also sometimes referred to as having water on the knee. Knee effusion can be the result of an injury, trauma, or a symptom of disease or other condition. Symptoms of knee effusion include pain, swelling, muscle stiffness, and bruising.

Fast Facts:

  • In some cases, physicians will opt to drain the fluid from the knee joint to help relieve pressure and pain.
  • Examining the fluid that is removed from the knee effusion can help make a diagnosis regarding an underlying condition that is causing the fluid to accumulate in the joint.
  • Patients who suffer from knee effusion at home can rest, use ice and NSAID pain medication. If symptoms do not improve, seek help from a physician.
