Strobel and Stedtfeld1 feel that examiners should learn three to five meniscus tests and use them on every patient since individual tests by themselves are inconclusive. For example, the validity of individual tests shows that Apley grinding test is 46 percent accurate, painful hyperextension 43 percent, Steinmann I sign 42 percent, and McMurray test only 35 percent. Interestingly, the most reliable sign is palpatory tenderness on the meniscus at the joint line (60-80 percent). According to Kapandji5, rotating the tibia internally will cause the medial portion of the meniscus to move anteriorly.
