Clinical tests

Tap to cycle positive / negative / not performed. Clusters beat any single test.

• —Lachman TestAnterior translation of tibia at 20-30° flexion; best single clinical test for ACL integritySn 85 · Sp 94
• —Pivot Shift TestHighest specificity; confirms ACL insufficiency via rotational instabilitySn 32 · Sp 98
• —Anterior Drawer Test (Knee)Anterior tibial translation at 90° flexion; less sensitive than LachmanSn 70 · Sp 90
• —Lever Sign TestNewer test; fist under calf, inability of heel to rise = positiveSn 83 · Sp 80
• —McMurray TestFlexion-extension + rotation; a palpable 'thud' on medial joint line correlates with medial meniscal tearSn 50 · Sp 89
• —Thessaly TestWeight-bearing rotation at 5° and 20° flexion; most sensitive meniscal testSn 56 · Sp 85
• —Apley Grind TestProne compression + rotation; good combined accuracy (87-90%)Sn 60 · Sp 80
• —Joint Line TendernessPalpation along medial/lateral joint line; sensitive screen but less specificSn 75 · Sp 50
