Gonococcal septic arthritis

Inflammation of a joint due to infection by the bacteria called gonococcus (Neisseria gonorrhoeae). The most frequently affected joints are knee, ankle or wrist. 

It is considered a sexually transmitted disease (STD). The bacteria reach the joint through the bloodstream.

It manifests with pain and swelling; in many cases, the joint is also red and warm to palpation. 

Diagnosis is made by clinical history and physical examination. It is confirmed by blood test and joint fluid analysis.

Treatment includes antibiotic, analgesic and anti-inflammatory drugs to control symptoms.

As it is considered a sexually transmitted infection, it is advisable to rule out other STDs such as HIV, syphilis and chlamydia, even in sexual partners.
