Gonococcal arthritis is a rare but serious complication of untreated gonorrhoea. It happens when the gonorrhoea bacteria spread through the bloodstream to the joints, causing painful inflammation. It’s part of disseminated gonococcal infection (DGI) and needs prompt antibiotic treatment to prevent joint damage.

How It Happens
| Step | Detail |
|---|---|
| 1. Genital gonorrhoea | Often asymptomatic, especially in women |
| 2. Bacteria enter bloodstream | Dissemination occurs in a small percentage |
| 3. Joint seeding | Bacteria settle in joints or tendons |
| 4. Arthritis develops | Painful swelling and inflammation |
Diagnosis
- Joint fluid aspiration and culture
- Blood cultures
- Genital, throat and rectal NAAT for gonorrhoea
- Joint imaging if needed
Treatment
- IV antibiotics initially (ceftriaxone)
- Transition to oral antibiotics
- Treatment of underlying genital gonorrhoea
- Partner notification and treatment
Prevention
- Regular STI testing catches gonorrhoea early
- Prompt treatment prevents dissemination
- Condoms reduce gonorrhoea risk
