Effusion: Water on the knee is known as an effusion. Causes include but are not limited to inflammatory issues including arthritis, synovitis, and gout/pseudo-gout. If there has been a recent injury then the fluid can be from blood accumulation from cartilage injuries, ligament injuries, fracture, or even patellar dislocation. You should see your doctor first to determine the cause.
