Joint Space Narrowing: Osteoarthritis (OA) or Rheumatoid arthritis (RA)

In Rheumatoid Arthritis (RA), Joint Space Narrowing (JSN) may be a symptom of (primary) osteoarthritis that gets worse with age. Patients with Rheumatoid Arthritis (RA) experience gradual impairment as a result of joint deterioration. The cartilage in joints allows joints to move freely and absorb impact. Ageing further deteriorates the cartilage in the joints and it starts to become worn, especially in your knees, hips, and hands. Conditions including Osteoarthritis (OA) and rheumatoid arthritis can cause joint space constriction. Various rheumatic disorders, such as osteoarthritis, rheumatoid arthritis, inflammatory arthritis, erosive osteoarthritis, gout, or systemic lupus erythematosus, can cause joint space constriction
