Injury to the posterolateral corner structures of the knee can cause
posterolateral rotatory instability, a condition that has attracted increased
attention over recent
years1. This injury
is often associated with cruciate ligament injury, and its diagnosis can be
difficult unless one has a high degree of clinical suspicion for an injury to
the posterolateral corner
structures2,3.
Although a number of treatment methods have been proposed over the past twenty
years2,4-12,
there has been considerable controversy regarding the optimal method of
surgical treatment for this injury. The consequences of missed or
unsuccessfully treated posterolateral rotatory instability can be profound:
reconstructed anterior or posterior cruciate ligaments can fail, and
persistent posterolateral rotatory instability may eventually cause pain,
instability, and even degenerative
changes13-17.
