Symptoms of nongonococcal septic arthritis
What clinical manifestations are typical of nongonococcal septic arthritis?
Abrupt onset of swelling, warmth, and pain involving one joint is the classic presentation, the exception being an infected joint prosthesis, where the presentation may be more indolent (delayed onset type). Many patients have serious underlying illnesses and 40% to 60% may be febrile or have chills. Large joints (knee, hip) are most commonly involved. Patients keep the knee or hip flexed, abducted, and externally rotated to maximize intracapsular volume. Both passive and active ranges of motion are very painful. Children and most adults refuse to use the involved extremity.
