How many positive meniscal findings are typically needed to rule in pathology?

• A. 2 or more
• B. 3 or more
• C. 1 or more
• D. 4 or more

Answer: (B)

When assessing suspected meniscal injury, combining several positive signs across different knee tests increases diagnostic certainty. A single positive finding can occur with benign pain or other knee issues, so it’s not enough to definitively rule in pathology. Requiring more positive findings makes the result more specific: the probability of a true meniscal tear rises as the number of positive tests increases. In this context, three or more positive meniscal findings provides the strongest evidence to rule in pathology, balancing accuracy and practicality better than just one or two positives. Four positives would be even more stringent but could miss true cases, and two positives, while helpful, are more prone to false positives.
