Septic arthritis, also known as infectious arthritis, is a condition characterized by joint inflammation caused by an infection from bacteria or a virus. This infection can result in stiffness and limited mobility of the affected joint. Symptoms of septic arthritis are similar to those of wear and tear arthritis, including redness, pain, and heat in the joint. Additionally, individuals may experience general infection symptoms such as fever, weakness, or a headache. It is possible for the infection to affect one or multiple joints.
Understanding the Causes of Septic Arthritis
Septic arthritis occurs when a joint becomes infected. The infection can be caused by various factors, such as bacteria, viruses, fungi, or even parasites. Additionally, septic arthritis can also be a result of trauma to the affected area or a blood-borne infection. This condition typically develops rapidly and is often accompanied by flu-like symptoms.
Diagnosis of Septic Arthritis
When it comes to diagnosing septic arthritis, a sample of the joint fluid is taken and cultured to determine the presence of any microorganisms. If the culture reveals a high concentration of white blood cells or lactate, it strongly indicates septic arthritis as the cause. It’s important to note that septic arthritis differs from osteoarthritis in terms of its rapid onset of symptoms.
