The comparisoni
“Her arthritis flared up with a red, swollen knee; arthrosis refers to the wear-and-tear, not the flare.”

¶
ARTHRITIS = inflammation. ARTHROSIS = joint degeneration.
ARTHRITIS (-itis = inflammation) is the inflamed form. ARTHROSIS (-osis = condition) is the non-inflammatory degenerative form — what used to be called osteoarthritis in UK clinical usage.

-ITIS = inflamed. -OSIS = condition.
