Joint Disorders

Joint disorders are medical conditions that affect the structure and function of synovial joints, leading to pain, inflammation, stiffness, swelling, and limited movement. Common types include osteoarthritis (wear?and?tear cartilage loss), rheumatoid arthritis (autoimmune joint inflammation), gout (uric?acid crystal deposition), and septic or infectious arthritis (bacterial joint infection).

These disorders often involve damage to cartilage, synovium, ligaments, tendons or surrounding muscles, and may progress slowly or flare acutely. Risk factors include aging, obesity, joint injury, repetitive strain, genetics, and autoimmune tendencies. Typical symptoms are joint pain at rest or on movement, morning stiffness, warmth and redness, crepitus (grating sounds), and reduced range of motion.

Diagnosis relies on clinical history, physical examination, and sometimes imaging (X?ray, MRI) or blood tests (autoantibodies, uric acid, inflammatory markers). Management aims to relieve pain, reduce inflammation and preserve joint function through non?pharmacological (weight?bearing reduction, physiotherapy, low?impact exercise) and pharmacological (NSAIDs, corticosteroids, disease?modifying drugs) measures. In advanced cases, joint injections, arthroscopic procedures, or total joint replacement surgery may be necessary.
