C. Osteochondritis dissecans
D. Osgood-Schlatter's disease
The mechanism of injury that leaves the posterior cruciate

A.
B.
C.
D.

patella to sublux?
A.
B.
C.
D.
Laterally
Superiorly
Medially
Inferiorly
Both varus and valgus stress tests may be successfully
performed if done only in the fully extended position.
The Lachman drawer test is preferred over other drawer
tests for immediately after an injury due to decrease
range of motion.
The pivot-shift test is designed to determine anterolateral
rotary instability; and is often used in evaluating
chronic conditions of the ACL.
BONUS
The McMurray test is used to determine the presence of
loose bodies in the knee and is performed by having the
athlete lie face down with the affected knee at 90 degrees
flexion and compressing downward on the injured leg.
One of the most important aspects of a good evaluation is
understanding the mechanism of injury by taking a
good history.
Most acute dislocations occur medially.
The infrapatellar fat pad often becomes wedged between the
knee articulations by constant kneeling or traumatized by
direct blows.
Most patellar fractures are the result of indirect trauma in
which a severe pull of the patellar tendon occurs
against the femur when the knee is semiflexed.
The medial meniscus is prone to disruption by valgus and
torsional forces.
An acute patellar dislocation is often associated with the
sudden twisting of the body while the foot or feet are
planted.
Fx of cartilage and underlying bone (snap)
