Could you use crutches for fluid on the knee?

It depends on the underlying cause of the knee fluid. Crutches are commonly used for stability and mobility when there is temporary weakness or injury in the leg, but in some cases, fluid on the knee may be caused by a more serious condition that requires different medical interventions. It's essential to consult with a healthcare professional for proper evaluation, diagnosis, and appropriate treatment. Self-treating without proper medical advice can lead to potential complications.
