Research Question

What is the diagnostic accuracy of a new dynamic clinical test for the detection of meniscal tears?
a) This might be of relevance because the current diagnostic gold standard (MRI) is expensive and not always available.
b) Are current testing methods inaccurate? Are clinical tests inadequate compared to MRI?

Introduction seemed contradictory; as seventy five per cent accuracy of diagnosis can be made on history alone (Daniel, 1982; DeHaven, 1975) followed by specific clinical tests with above average accuracy. Very brief essentially, non-existent literature review. Besides mention of the population susceptible to meniscal injury, other relevant information pertaining to the injury wasn’t briefed. Such as, the mechanism of injury as well as the classic signs and symptoms experienced by an individual after meniscal pathology. Neither the introduction nor the brief literature review goes over what exactly sensitivity and specificity imply in the results. Sensitivity being how good the test is at detecting meniscal tears and specificity being how good the test is at identifying normal knee (Mohan, 2007). Also, there is no mention of what constitutes a false-positive and a false-negative result encountered during
