The Valgus and Varus tests

EFFUSION
The timing and amount of joint effusion are important clues to the diagnosis. Rapid onset (within two hours) of a large, tense effusion suggests rupture of the anterior cruciate ligament or fracture of the tibial plateau with resultant hemarthrosis, whereas slower onset (24 to 36 hours) of a mild to moderate effusion is consistent with meniscal injury or ligamentous sprain.
