 In meniscal tears, pressing on the joint line on the affected side typically produces tenderness.The McMurray test involves pressing on the joint line while stressing the meniscus (using flexion–extension movements and varus or valgus stress).Similar tests are the Steinmann test (with the patient sitting) and the Apley grind test (a grinding maneuver while the person lies prone and the knee is bent 90°) and the Thessaly test (flexing the affected knee to 20 degrees, pivoting on the knee to see if the pain is reproduced).
