  • Joint-fluid analysis
  • Blood-tests
  • Phlegm, urine, and spinal fluid tests
  • Bone scan
  • X-rays and MRI scan
  • Radionuclide scans.

Upon diagnosis, the following methods are used to treat septic arthritis:

  • Antibiotic Medications

Immediately after diagnosis, proper medications are used to limit the symptoms. Veins act as the passage for injecting high dosage of drugs into the body. Afterwards, oral method of giving medications is used. Medications provide instant relief from symptoms. They are to be used continuously for several weeks for better results.

AT one end of the tube is placed a small video camera. This camera provides proper internal viewing. Afterwards, a suction and drainage tube is used to remove infected fluid.
