Which finding is most indicative of septic arthritis requiring urgent referral?

• A. Chronic joint stiffness.
• B. Acute joint swelling with fever, warmth, and severe pain and inability to bear weight.
• C. Mild pain with full ROM.
• D. Pain with rotational movement.

Answer: (B)

Septic arthritis is a medical emergency, and the hallmark is an abrupt, intensely painful, swollen joint with warmth and fever, often with the inability to bear weight. This combination signals infection inside the joint space that can rapidly damage cartilage and spread systemically if not treated quickly. Urgent referral allows prompt joint drainage and IV antibiotics, which dramatically improves outcomes and reduces complications. Chronic joint stiffness points to long-standing inflammatory or degenerative processes rather than an acute infection. Mild pain with full range of motion suggests a non-septic cause, and pain with rotational movement without systemic signs is more compatible with mechanical or inflammatory issues rather than septic arthritis.
