No signs of cellulitis or surrounding soft tissue abscess. Systemic exam reveals tachycardia and febrile status.
Treatment Protocol
Urgent joint aspiration (arthrocentesis) for synovial fluid analysis (cell count, Gram stain, culture, and crystals). Initiate empiric intravenous broad-spectrum antibiotics pending culture results. Orthopedic consultation for urgent surgical washout/debridement. Pain management with analgesics and joint immobilization.
