M02.162
Postdysenteric arthropathy, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Postdysenteric arthropathy is a type of joint inflammation that occurs after an episode of dysentery, a severe intestinal infection. This condition specifically affects the left knee in this case, leading to joint pain and swelling that can impact daily activities. Recognized under the ICD-10 code M02.162, it is part of a broader category of reactive arthritis, which is triggered by infections elsewhere in the body. Although uncommon, understanding its causes, symptoms, and management options can help individuals affected by this condition understand their health better.
Causes & Symptoms
Clinical Causes: Infection with bacteria such as Shigella, Salmonella, Yersinia, or Campylobacter, which cause dysentery. Immune system's response to a recent bacterial infection, leading to inflammation in the joints. Genetic predispositions that may increase susceptibility to reactive arthritis. Environmental factors and lifestyle choices, such as smoking, that may influence immune reactions.
Key Symptoms: Persistent pain in the left knee, often described as aching or throbbing. Swelling and tenderness around the joint area. Reduced range of motion or stiffness in the knee. Warmth and redness over the affected joint. General fatigue or malaise in some cases. Associated symptoms of the initial dysentery infection, such as diarrhea and abdominal discomfort.
Diagnostic & Treatment
Diagnosis Path: Diagnosing postdysenteric arthropathy involves a combination of clinical evaluation and diagnostic tests. A healthcare provider will review the patient's medical history, especially recent gastrointestinal infections, and perform a physical examination of the knee. Laboratory tests, such as blood work, are used to look for signs of inflammation and past bacterial infection. Joint aspiration may be performed to analyze the synovial fluid for bacteria or inflammatory markers. Imaging studies like X-rays or MRI scans can help assess joint damage and distinguish this condition from other forms of arthritis.
Treatment Protocols: While specific treatment plans are tailored to individual needs, management typically involves:
