**What is Septic Arthritis?**
**Definition:**
Septic arthritis is a bacterial infection of the fluid and tissues within a joint. It is a serious condition that can lead to permanent joint damage if left untreated.
**Causes:**
Septic arthritis is caused by bacteria entering the joint through a wound, surgery, or an infection in another part of the body that spreads to the joint through the bloodstream. Common bacteria that cause septic arthritis include:
* Staphylococcus aureus (staph)
* Streptococcus pneumoniae (pneumococcus)
* Pseudomonas aeruginosa
* Gram-negative bacilli
**Symptoms:**
* Sudden onset of severe pain, swelling, redness, and warmth in the affected joint
* Fever and chills
* Difficulty moving the joint
* General malaise and weakness
**Diagnosis:**
Septic arthritis is diagnosed through a physical examination, medical history, and tests, including:
* Blood cultures
* Joint fluid analysis (arthrocentesis) to check for bacteria and inflammatory markers
**Treatment:**
Septic arthritis is a medical emergency and requires immediate treatment to prevent joint damage. Treatment involves:
* **Antibiotic therapy:** Intravenous antibiotics are administered to kill the bacteria.
* **Drainage of infected fluid:** The infected joint fluid is drained to remove the bacteria and relieve pain.
* **Immobilization:** The affected joint is immobilized to prevent further damage.
* **Surgery:** In severe cases, surgery may be necessary to remove damaged tissue or repair the joint.
**Complications:**
Untreated septic arthritis can lead to:
* Joint destruction and permanent disability
* Bloodstream infection (sepsis)
* Lung damage (empyema)
* Heart infection (endocarditis)
* Meningitis
**Prevention:**
* Treat skin infections and wounds promptly.
* Practice good hygiene to avoid exposure to bacteria.
* Get vaccinated against bacteria that can cause septic arthritis, such as pneumococcal and meningococcal vaccines.
