Meniscus tear is not osteophyte, there are some differences in the pathogenesis, clinical manifestations and imaging manifestations between the two. 1. Pathogenesis: meniscus is the articular cartilage of the knee joint, meniscus tear is trauma, prolonged weight bearing and other reasons, resulting in meniscus damage. While osteomalacia of knee joint is caused by old age, trauma and other reasons, resulting in irregular bone damage, calcification of calcium salt deposits, and the formation of marginal bone cumbersome. 2. Clinical manifestations: both meniscus tear and osteophytes can cause knee pain, but meniscus tear can cause knee popping and sudden inability of knee flexion and extension. 3. Imaging performance: osteophytes can be seen in the X-ray irregular bone destruction, edge of the bone cumbersome formation, while meniscus tear can be seen in the magnetic resonance high signal shadow. Knee pain and discomfort occurs, if the symptoms continue unrelieved. It is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment.
