M13.1: Monoarthritis, not elsewhere classified
Monoarthritis, not elsewhere classified (NEC), is the term used to describe a condition where a single joint is inflamed. This inflammation can be caused by a variety of factors such as injury, wear and tear, or an underlying disease like arthritis. The affected joint may become swollen, stiff, red, warm to the touch, and painful, particularly while moving or applying pressure. Symptoms can appear rapidly in acute cases, or gradually over time in chronic cases. While this condition can affect any joint in the body, it most commonly affects larger joints such as the knee or hip. It's important to note that monoarthritis can be a sign of a more serious condition, and determining the underlying cause is essential for proper management.
