Which test is most specific for diagnosing meniscal pathology?

• A. Thessaly
• B. Joint Line Tenderness
• C. Pain with squatting
• D. McMurray

Answer: (D)

The most specific test for meniscal pathology is one that directly creates the mechanical stress on the meniscus by combining knee flexion, rotation, and extension. This maneuver targets the cartilage and its edges so that a tear is more likely to produce a distinct sign, such as a localized click or sudden pain as the torn fragment catches between femur and tibia. When you get that specific reproducible sign, it strongly points to a meniscal tear rather than other knee issues. Other tests can indicate meniscal irritation but are less specific. For example, a test involving squatting or general joint line tenderness can be positive with other knee problems like osteoarthritis or ligamentous injuries. While the Thessaly test can be helpful and may pick up tears, its findings aren’t as specifically tied to a torn meniscus as the targeted maneuver that reproduces the mechanical event.
