Re: knee swollen since accident

Draining water from the knee is a very simple procedure.  They simply insert a syringe and draw it out.  They once got almost two cups full from mine.  They inject you with Novocain first so it doesn't hurt at all.

If you have water on the knee you could easily have torn cartilage as well.  A visit to an orthopedic doctor will drain your water and give you more answers to a problem that could give you continuous difficulty if you don't go.
