Plural of arthrosis; various joint diseases or degenerative conditions affecting multiple joints.
From Greek 'arthron' (joint) + '-osis' (condition or disease). The plural form of arthrosis, which dates back to ancient medical terminology describing joint ailments.
The Ancient Greeks couldn't see inside joints with cameras like we can now, but their suffix '-osis' (meaning 'condition of becoming') was so useful that modern doctors still use it for diseases from osteoporosis to neurosis.
