Inflammation of the knee joint, causing pain, swelling, and reduced movement.
From Greek 'gony' (knee) plus the medical suffix '-itis' (inflammation). Common in medical terminology since the 1700s to describe joint inflammation.
The ancient Greeks loved the word 'gony' for knee so much that it appears in 'goniometer' (angle measurer) and 'gonitis'—it's like they were obsessed with understanding the joint's mechanics!
