Hib septic arthritis affects single large joints (eg, knee, ankle, hip, elbow).

Symptoms, usually preceded by a URTI, include decreased range of motion, erythema, and warmth and swelling in affected joints, in addition to fever.

In adults, joint involvement can be monoarticular or polyarticular.

Extra-articular sites of infection, including those associated with meningitis, pneumonia, cellulitis, and sinusitis, may also be evident.
