What does it mean when the results of a knee mri states there is physiologic joint fluid?

Extra fluid: joints have some fluid, your MRI is indicating you have an extra amount of joint fluid in your knee. Talk to your doctor about management. Be well.

Normal: If that is simply all that is stated it most likely is completely normal

Normal : In other words, there is a normal amount of fluid in a normal knee; and that is seen on your MRI, meaning there is not an increase in the fluid seen in your knee beyond normal- which would be considered a knee effussion.

Not to worry: There is a small amount of fluid in the joint normally, and some Doctors describe this as "physiologic". This means no significant or abnormal fluid in the knee.
