Suppurative arthritis

Suppurative arthritis is a severe form of arthritis characterized by inflammation and the accumulation of pus in the joints. It is also known as septic arthritis or infectious arthritis. This condition is typically caused by a bacterial infection, although it can also be caused by fungal or viral infections.

Causes

The most common cause of suppurative arthritis is a bacterial infection. The bacteria can enter the joint through the bloodstream from an infection elsewhere in the body, or directly through a wound or surgical incision. The most common bacteria involved are Staphylococcus aureus and Streptococcus. Other bacteria, such as Neisseria gonorrhoeae, can also cause suppurative arthritis, especially in sexually active young adults.

Symptoms

The symptoms of suppurative arthritis typically include severe pain in the affected joint, swelling, redness, and warmth. The patient may also have a fever and feel generally unwell. The knee is the most commonly affected joint, but suppurative arthritis can affect any joint in the body.

Diagnosis

The diagnosis of suppurative arthritis is typically made based on the patient's symptoms, a physical examination, and laboratory tests. The doctor may take a sample of fluid from the affected joint to test for the presence of bacteria. Imaging tests, such as an X-ray or MRI, may also be used to assess the extent of the joint damage.

Treatment

The treatment of suppurative arthritis typically involves antibiotics to treat the infection and sometimes surgery to drain the pus from the joint. Pain relief and physical therapy may also be needed to help the patient regain normal joint function.

Prognosis

With prompt and appropriate treatment, most patients with suppurative arthritis can recover fully. However, if left untreated, suppurative arthritis can lead to permanent joint damage and disability.
