Final answer:
The chronic joint disease characterized by inflammation, pain, stiffness, and deformity of the affected joints is Rheumatoid arthritis.
Step-by-step explanation:
The chronic joint disease characterized by inflammation, pain, stiffness, and deformity of the affected joints is Rheumatoid arthritis. In Rheumatoid arthritis, the joint capsule and synovial membrane become inflamed, leading to severe damage or destruction of the articular cartilage. This results in joint deformity, loss of movement, and disability. Treatments for Rheumatoid arthritis aim to alleviate symptoms and may include exercise, anti-inflammatory medications, disease-modifying drugs, or surgery.
