criffer said:Incorrect, it would not be the PCL as PCL is about 10 times stronger than the ACL and the mechanism of injury is exactly opposite of the biomechanics of the PCL, the PCL is damged when the tibia moves to far/fast posteriorly on the femur like in a hyper-flexion injury or a "knee into the dashboard injury" during a car accident, if anything major esp with a hyperextension mechanism of injury it would be the ACL not the PCL
But I do agree with the info on waiting and getting insurance as no major further damage would be done to the knee by waiting as long as he takes it easy
op you beat me..

Anterior Cruciate Tears
* Clinical Features - although isolated ACL tears may occur, they are much more likely to be associated with injuries to other structures such as other knee ligament and the posterior horn of the meniscus. Once the ACL has torn, this may then lead to rotational instability in the knee due to progressive damage to the capsular ligaments.
* ACL tears occur most frequently during hyper-extension injuries (knee pushed backwards when it's straight), or during a rotational injury with the knee flexed (changing direction when running). The knee swells badly over 24 hours due to bleeding within the joint.
but can happen with out swelling
