In simple words: Pyogenic arthritis is a joint infection caused by bacteria. It can cause fever, pain, swelling, and redness in the affected joint. If not treated, it can lead to permanent joint damage. Treatment typically involves antibiotics and draining any pus from the joint.

Pyogenic arthritis, also known as bacterial, infectious, or septic arthritis, occurs when an infectious organism, typically bacteria, causes inflammation within a joint. This can lead to permanent joint damage if left untreated.Symptoms often include fever, swelling, redness, and intense pain in the affected joint, usually the knee or hip. Diagnosis involves evaluating the patient's history, including recent joint surgery, infections, or IV drug use, along with a physical exam, blood culture, joint fluid analysis, and X-rays. Treatment includes antibiotics and drainage of pus.

Example 1: A 25-year-old male presents with acute pain, swelling, and redness in his right knee. He has a fever and reports recent intravenous drug use. Joint aspiration reveals purulent fluid, and cultures confirm bacterial infection.Diagnosis: M00 Pyogenic arthritis., A 60-year-old female with a history of rheumatoid arthritis develops fever, pain, and swelling in her left hip.Fluid analysis confirms a bacterial infection. Diagnosis: M00 Pyogenic arthritis., A child presents with fever, refusal to bear weight on his left leg, and swelling in the left ankle. Blood cultures and joint aspiration confirm bacterial infection. Diagnosis: M00 Pyogenic arthritis.

Documentation should include the type of infection (bacterial, fungal, etc.), location of the affected joint(s), laterality (left or right), causative organism if identified, and any associated symptoms (fever, swelling, pain, etc.).

** It is essential to distinguish pyogenic arthritis from other forms of arthritis, such as osteoarthritis or rheumatoid arthritis, as treatment approaches differ significantly.Prompt and aggressive treatment of pyogenic arthritis is crucial to prevent long-term joint damage.
