„Erler-Zimmer GmbH & Co. KG 3D Model of Arthritis of the Knee Joint 3D Model:
- Model: MP2119
- Clinical History:
An 82-year-old man had tuberculosis in childhood. He had been suffering from painful, swollen knees for the past 10 days before hospital admission. Examination showed inflammation in the knee joint, painful to move, which improved slightly after antibiotic therapy and rest. X-ray examination showed destruction of the knee joint and a mid-thigh amputation was performed 3 days after admission. Postoperative recovery was satisfactory. - Pathology:
The specimen shows the articular surfaces of the femur and tibia. The articular surfaces are very eroded. They are brown in color, very irregular, and contain floating adhesions and yellow plaques of necrotic material. Normal articular cartilage is absent. The femoral condyles contain several irregular, variably sized bony outgrowths (up to 1 cm in diameter). Staphylococcus aureus was cultured from the joint. This is an example of a purulent arthritic joint previously affected by tuberculosis. - Additional Information:
Suppurative arthritis is usually caused by a bacterial infection in a joint. Diagnosis is made by analysis of synovial fluid, including microscopic examination and culture. Suppurative arthritis is also called pyarthritis, bacterial arthritis, or septic arthritis. Tuberculous septic arthritis should be considered in patients presenting with acute or chronic monoarthritis who have an abnormal chest x-ray, eosinophilia, or a history of tuberculosis.
