What is suprapatellar joint effusion with synovitis?

The definitions: Supra=means above, so suprapatellar means above the patella. Synovitis=inflammation of the synovium, the tissue lining of the joint capsule (the fibrous, tough tissue surrounding your joint--see picture). So, you have sme fluid/swelling above the patella and inflammation along the edges of your joint. These terms =big bucks? :-)) hope that makes sense. Good luck.
