Septic arthritis usually requires immediate treatment with antibiotics which can improve symptoms within 48 hours. However, certain infections caused by fungi need treatment with anti-fungal medications, while viral infections usually have to run their course without treatment. To prevent accumulation of pus from the infection, which can damage the joint, pus may be drained with a needle, tube, or surgery. Other treatment may include:

  • medications (for pain and fever)
  • physical therapy (to maintain muscle strength)
  • splinting the joint (to relieve pain)
