What are the two main categories of meniscal tears?

• A. Inflammatory and Degenerative
• B. Traumatic and Degenerative
• C. Traumatic and Inflammatory
• D. Acute and Chronic

Answer: (B)

Tears of the meniscus are best understood by how they occur and the condition of the tissue—two main categories: traumatic and degenerative. Traumatic tears happen from an abrupt twisting or impact to a knee with otherwise normal meniscal tissue, so they’re common in younger people after a specific incident. The tear pattern can be vertical or bucket-handle, and healing is more likely when the tear is in the outer, well-vascularized part of the meniscus, making repair a realistic option in many cases. Degenerative tears come from chronic wear and tear, often in older individuals, and can happen with little or no clear injury. The tissue quality is poorer, so tears tend to be horizontal or complex and have limited healing potential. Management tends toward symptom relief with partial meniscal removal or conservative therapy, depending on the tear and symptoms. Understanding this distinction helps explain why these two categories are used: they reflect both how the injury happened and the tissue’s ability to heal. Other terms like inflammatory or a simple acute vs chronic split are less accurate descriptors for how most meniscal tears are categorized.
