In this retrospective study we examine the effectiveness of the here named “Twist test” in diagnosing meniscal pathology. In preparation for this study, a literature review was conducted to look at commonly used “gold standard” exam maneuvers utilized in the diagnosis of meniscal lesions. The data from these studies was used as comparisons against the twist test. Medical records of patients who underwent knee arthroscopy from the 2013 calendar year were pulled and assessed for positive or negative Twist test results. These results were then correlated with Magnetic Resonance Imaging (MRI), and more definitively, arthroscopic findings. With this data, we calculated the sensitivity, specificity, and positive predictive value (PV+) of the exam maneuver. Our results suggest that this maneuver may have clinical relevance in diagnosing meniscal lesions.
