• A. Fibromyalgia
• B. DJD
• C. DDD
• D. Osteoarthritis

Answer: (D)

Osteoarthritis is the primary wear-and-tear, age-related arthritis. It happens when the protective cartilage in the joints gradually wears away, leading to cartilage breakdown, changes in the underlying bone, and bone spur formation. This degenerative process most commonly affects weight-bearing joints such as the knees and hips, as well as the hands, and it manifests with activity-related pain, stiffness after inactivity, and possible joint crepitus. Although the term degenerative joint disease is sometimes used, the classic description of aging-related, wear-and-tear joint degeneration is osteoarthritis. Fibromyalgia involves widespread pain without structural joint damage, degenerative disc disease concerns the spine, and degenerative joint disease is basically another term for OA but OA is the standard, most accurate label for this scenario.
