LARS RECONSTRUCTION

OBJECTIVE: To discuss the diagnosis and treatment of posterolateral corner injury
of the knee joint, and to evaluate the clinical results after LARS reconstruction.
METHODS: Sixteen cases of posterolateral corner injury of the knee were treated
with existing serious varus or external rotation. At a mean follow-up of 23 months (9
to 40 months), we evaluate the clinical results using Lysholm scoring systems. Varus
stress test showed that instability of varus was more than 10 degrees under the 30
degrees and 0 degrees of genuflexion respectively and external rotation test showed
that instability of external rotation was more than 10 degrees when compared with
normal side. Thirteen cases complicated by rupture of anterior cruciate ligament, 4
case by rupture of posterior cruciate ligament and 1 cases by rupture of both
ligaments. RESULTS: All patients were followed 9 to 40 months and no patients had
instability of the knee. The range of motion of the knee was from 110 degrees to 130
degrees of flexion and from 0 degrees to 5 degrees of extension. Posteroperative
scores were from 86 to 100 according to Lysholm scoring systems. CONCLUSION:
Injuries to posterolateral structures are frequently encountered and failure to
recognize and treat this associated injury may lead to stretching or failure of the
cruciate reconstruction. Early surgical reconstruction in knees with combined
ACL/PCL and posterolateral instabilities achieved the best clinical results and a high
rate of patient satisfaction. This injury can result in a significant degree of disability
for patients.
