An Anatomic Single-Tendon Posterolateral Corner Reconstruction Technique With Suspensory Fixation and Internal Brace.

Abstract

The role the posterolateral corner (PLC) plays in controlling varus and posterolateral rotatory laxity is crucial, especially in the setting of combined cruciate ligament injuries. PLC reconstruction is essential to restore knee laxity, helping to reduce the risk of cruciate ligament graft failure. The LaPrade technique is the most used anatomic PLC reconstruction technique; however, it requires 2 tendon grafts. Advancements in techniques, including the use of adjustable-loop suspensory fixation devices and internal brace, have been introduced in recent years. The purpose of this Technical Note is to describe a single-tendon anatomic PLC reconstruction technique with adjustable-loop femoral fixation and internal brace. The advantages of this technique are the need for only 1 tendon for anatomic PLC reconstruction, the possibility of graft retensioning through the adjustable-loop femoral fixation until satisfactory stability is achieved, and graft protection offered by the internal brace during the healing period.
