I’m pretty sure the test the sideline guy does with his hands is extremely high in predictive value.
The Lachman test has a sensitivity of 77.7% for acute ACL ruptures and 84.6% for subacute or chronic ACL ruptures.
Specificity
The Lachman test has a specificity of more than 95% for both acute and subacute or chronic ACL ruptures.
Accuracy
The Lachman test is considered to be the most accurate test for diagnosing ACL injuries. [Reply]

Just cast your mind back to when Charles Omenihu tore his ACL. The process was straight forward. Initial fears are only from touching the knee. But clearly he's had MRI's and it's not saying what they thought it was. Could it be something else? Yes. But to now say they may have to wait a week for answers? How many ACL injuries take a week to diagnose? The only case I can find is Vonn Miller. On thanks giving day against the Lions his knee got hit and he left the game. The ACL was feared to have been torn. Next day they said "it's a knee sprain". He was put on IR but about nine days after the injury he had exploratory surgery and it was discovered he did tear his ACL. Other than that most ACL cases are cut and dry. So either the MRI isn't showing it, or he simply hasn't torn his ACL. Let's pray it's the latter. [Reply]
