What Causes Septic Arthritis?
The main causes of septic arthritis are viruses, fungi, and bacteria, such as staphylococcus aurous, and in some patient E. coli may also cause infection. In sexually active young adults gonorrhea may be the cause as well as tuberculosis.
The joint infection usually manifest when there are certain risk factors involved, such as medication of autoimmune disorders, intravenous drug users, post-operative surgery infection, or prior medical conditions such as alcoholism, sickle cell disease, and diabetes as well as rheumatic diseases.
Patients who have prosthetic joints or prosthetic joint surgery are also at risk and usually in the first three months of receiving the implant and can last up to two years afterwards during the healing process. Those prosthetic joint infections are usually as a result of S aureus and the spread of infectious foci through the blood stream.
