M02.869
Other reactive arthropathies, unspecified knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Reactive arthropathies are a group of joint disorders that develop as a reaction to an infection elsewhere in the body. When this condition affects the knee and is classified as unspecified, it falls under the ICD-10 code M02.869. This condition involves inflammation of the knee joint that isn't caused directly by typical arthritis but is triggered by an immune response to another infection. Understanding this condition can help patients recognize symptoms and seek appropriate medical attention for management.
Causes & Symptoms
Clinical Causes: Previous bacterial infections, commonly in the genitourinary or gastrointestinal systems Infections such as Salmonella, Shigella, Yersinia, or Chlamydia Immune system response to the infection, leading to joint inflammation Genetic predispositions that may influence susceptibility Other unidentified or less common infectious triggers
Key Symptoms: Pain in the affected knee, often during movement Swelling around the knee joint Reduced range of motion due to discomfort and swelling Warmth and redness over the knee area Possible systemic symptoms like fever or malaise, depending on the infection Tenderness upon touch or movement
Diagnostic & Treatment
Diagnosis Path: Physical examination to assess swelling, warmth, and joint mobility Medical history review focusing on recent infections or illnesses Blood tests to identify markers of inflammation and possible infectious agents Joint aspiration, where a sample of fluid from the knee is analyzed for signs of infection or inflammatory cells Imaging studies such as X-rays or MRI scans to evaluate damage or other joint issues
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and decrease inflammation Physical therapy to maintain joint mobility and strengthen surrounding muscles Rest and elevation of the affected knee to reduce swelling Antibiotic therapy if an active infection is identified or suspected In severe cases, corticosteroid injections into the knee joint to control inflammation Surgical intervention, such as joint drainage or other procedures, in rare or persistent cases
