I had a total knee replacement a year ago. I have been having alot of pain. Now they drained some of the fluid in my right knee. Why would I have fluid on the knee when I had a total knee replacement. Also what does it mean? They took the fluid and did a byopsy on the fluid, what are they looking for??
