  • Septic arthritis
  • Viral arthritis (e.g., hepatitis, HIV)

  • Calcium pyrophosphate deposition disease (CPPD)
  • Hemochromatosis

  • Systemic lupus erythematosus (SLE)

  • Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) for rheumatoid arthritis
  • Serum uric acid levels for gout


Pain Management: Analgesics and anti-inflammatory medications.


Physical Therapy: Exercise programs to improve joint function and reduce pain.


Joint Protection Techniques: Education on preserving joint function in daily activities.


Disease-Modifying Antirheumatic Drugs (DMARDs): For autoimmune conditions like rheumatoid arthritis.


Lifestyle Modifications: Weight management, proper nutrition, and regular exercise.


Surgery: In severe cases, joint replacement or repair may be considered.


Effective management requires a comprehensive approach, often involving collaboration between rheumatologists, orthopedic surgeons, and physical therapists. Individualized treatment plans are essential based on the specific diagnosis and the patient’s overall health.
