Title: knee dislocation<br/>Author: Brian Corwell<br/><a href='http://umem.org/profiles/faculty/294/'>[Click to email author]</a><hr/><p>
Beware of spontaneous reduction masking the true injury!</p>
<p>
Knee dislocations are rare due to supporting ligaments (MVCs, falls, sports)</p>
<p>
but can be seen after minor trauma in obese patients.</p>
<p>
Named by the direction of the displacement of the tibia relative to the femur</p>
<p>
- Anterior and posterior are most common</p>
<p>
Dislocations involve disruption of at least 2 of the major knee ligaments (ACL/PCL most common)</p>
<p>
Usually associated with large hemarthrosis however capsular tearing may allow dissipation of the blood into adjacent soft tissue.</p>
<p>
Consider a spontaneously reduced knee dislocation in those with a significant mechanism of injury in the setting of multidirectional instability,</p>
