Meniscal tears are common in sport medicine practice. Many articles and textbooks discuss the relative validity of the different components of the physical examination with respect to their sensitivity, specificity, and positive/negative predictive values as if they were diagnostic tests. In this article, we demonstrate why this approach is limited, including the heterogeneous nature of meniscal tear pathology (e.g., posterior vs anterior). Therefore, in this article, we categorize all the published tests in the literature with regards to the mechanism underlying a positive test. We believe our approach provides the clinician with additional tools to diagnose tears. Future research should explore predictive models based on the different components accounting for heterogeneous pathology and different patient contexts.
