Water on the knee

'Water-on-the-knee' should really probably be called 'fluid-in-the-knee'. The fluid is not just water, and the fluid it is IN the knee not ON it.

The knee joint cavity is lined with a membrane that produces lubricating fluid to help the smooth movement of the knee in bending and straightening. This fluid is normally like egg white, and the knee cavity normally contains a little under a teaspoon (less than 3.5 millilitres) of this fluid. It is called 'synovial fluid' and the membrane that produces the fluid is called 'the synovium' or the 'synovial membrane'.
