Arthritis is broadly categorized based on the presence or absence of inflammation. Arthritis due to inflammation is called inflammatory arthritis. If there is lack of any signs and symptoms of inflammation, it is considered non-inflammatory type of arthritis. This broad category is important in planning for long term management, since there is a significant difference on these two types of arthritis. The most common cause of non-inflammatory arthritis is osteoarthritis, also referred to as degenerative arthritis. Common types of inflammatory arthritis are rheumatoid arthritis, spondyloarthritis, psoriatic arthritis, lupus-related arthritis, reactive arthritis, and gout.
