Pannus formation in rheumatoid arthritis is associated with which outcome?

Explanation:
Pannus is the proliferative, inflammatory tissue that forms in the rheumatoid joint. It invades and damages cartilage and the underlying bone, and as the inflammatory process matures, this tissue often becomes fibrotic, turning into scar-like tissue within the joint. That fibrotic transformation best captures the outcome associated with pannus—replacement of normal joint structures by scar tissue. It is not a sign of cartilage regeneration, nor does it reflect a decrease in synovial thickness or repair of bone; rather, it marks a destructive, fibrotic process in the joint.
