Joint spaces are aseptic areas, meaning that they do not contain microorganisms. Any injury to the joint space could cause the entry of microorganisms, with the potential to cause infection. Septic arthritis refers to the infection of a joint space with microorganisms, usually bacteria. This invasion initiates a process of inflammation and causes irreversible damage to a joint cavity. Patients typically present with pain, swelling, decreased motion, and inability to use the joint. When bacteria enter a joint space, the host immune system responds by concentrating inflammatory cells within the joint. While inflammatory cells serve to eliminate the bacteria, they also produce substances that not only attack bacteria but also could destroy the joint space. These substances are called enzymes, and they could damage the cartilage (translucent fairly elastic tissue around the joint) and adjacent bone in the process. Because cartilage has a poor ability to cure itself, this process may lead to irreversible damage and chronic joint dysfunction. Studies have found that signs of early joint damage can be found within hours following joint infection. This is true even if antibiotic therapy (medicine to fight the infection) is started within 24 hours of infection. Also, delay in treatment has been related to poor outcome. However, the best method of treating septic arthritis has yet to be determined. Currently, there are two accepted ways for treating septic arthritis: serial needle aspiration (introducing a needle in the joint to aspirate the inflammatory liquid), and surgical lavage (opening and cleaning the joint space in the OR under anesthesia). Antibiotics are also used with these two forms of treatment. Supporters of surgery believe that the most dependable method of eliminating bacteria from a joint space is through arthrotomy (opening the joint with a surgical incision) and lavage (irrigation of the joint with copious saline solution) .Promoters of serial needle aspiration support this method because it is quick, does not require opening the joint space, and can be performed without anesthesia.At present, there are no conclusive studies comparing the two techniques. Hopefully, this study will help delineate the best course of management.
