In medicine and, specifically, rheumatology, synovitis is "inflammation of a synovial membrane. It is usually painful, particularly on motion, and is characterized by a fluctuating swelling due to effusion within a synovial sac."[1]

Synovitis may be due to connective tissue diseases such as rheumatoid arthritis and systemic lupus erythematosus.

Physical examination

The physical examination is more specific than sensitivity in its accuracy for detecting synovitis.[2][3]
