Why joint pain isn't always caused by the same mechanism
In short: Not all arthritis is created equal. This video breaks down the fundamental biological differences between wear-and-tear conditions and systemic inflammatory diseases, using rheumatoid and osteoarthritis as primary examples.
The distinction lies in the underlying pathology of the joint. Inflammatory arthritis, such as rheumatoid arthritis, is characterized by a high concentration of white cells within the joints. This immune response triggers classic signs of inflammation, including pain, redness, and swelling.
In contrast, non-inflammatory arthritis typically involves mechanical wear-and-tear. Osteoarthritis serves as the primary example of this category, where joint issues stem from physical degradation rather than an active immune-driven inflammatory process.
