A medical condition involving the accumulation of pus within a joint cavity, causing inflammation and infection.
From Greek 'arthron' (joint) + 'empyesis' (suppuration or pus formation). The term combines the joint prefix with the medical suffix describing pus buildup, evolving from 19th-century medical terminology.
This word perfectly captures how medical professionals name diseases by stacking Greek root words like building blocks—each root tells you exactly what's wrong, so doctors can communicate precisely about the infected joint.
