This patient is presenting with a history of osteoarthritis and rheumatoid arthritis with systemic symptoms and pain, erythema, and edema of her knee suggesting a diagnosis of septic arthritis. The best initial step in management is aspiration of the joint. Septic arthritis typically occurs in patients with risk factors for damage to a joint such as osteoarthritis, rheumatoid arthritis, or trauma. Symptoms include systemic symptoms, pain, erythema, and edema of the joint. The best initial step in management is aspiration of the joint for diagnosis (often preceded by radiography), followed by broad spectrum antibiotics and surgical drainage. Incorrect Answers: Answer 1: CT would not be indicated to further evaluate septic arthritis. Radiography would be done initially followed by aspiration. Answer 2: Broad spectrum antibiotics would be indicated after aspiration has been performed for an initial analysis and culture. Answer 3: Surgical drainage is appropriate management in conjunction with broad spectrum antibiotics but should be performed after initial aspiration. Answer 4: Conservative therapy is not appropriate in septic arthritis and could result in severe damage to the joint. Prompt diagnosis and treatment is necessary. Bullet Summary: Septic arthritis presents with pain, erythema, and edema of the joint, and the best initial step in management is radiography followed by aspiration of the joint.
