BACKGROUND The clock-face method to identify the femoral posterior cruciate ligament (PCL) attachment has poor accuracy and reproducibility. Measurements of clinically relevant anatomic structures would provide more useful surgical guidance. The purpose of the present study was to describe the attachments of the anterolateral and posteromedial bundles of the PCL relative to relevant landmarks t...

BACKGROUND The posterior cruciate ligament (PCL) is the strongest ligament of the knee, serving as one of the major passive stabilizers of the tibio-femoral joint. However, despite a number of experimental and modelling approaches to understand the kinematics and kinetics of the ligament, the normal loading conditions of the PCL and its functional bundles are still controversially discussed. ...

Posterior cruciate ligament (PCL) injuries usually constitute part of a multiligament injury. Isolated PCL injuries account for only approximately 3% of all ligament injuries. No consensus on optimal surgical reconstruction exists. The PCL is a double-bundle structure that functions in an anisometric manner. Biomechanical studies have shown that re-creating the PCL femoral double-bundle configu...

Isolated posterior cruciate ligament (PCL) tears are much less frequent than anterior cruciate ligament (ACL) tears.Abrupt posterior tibial translation (such as dashboard impact), falls in hyperflexion and direct hyperextension trauma are the most frequent mechanisms of production.The anterolateral bundle represents two-thirds of PCL mass and is reconstructed in single-bundle techniques.The PCL...

An increasing concern has been given to the rotation stability of the knee in the setting of an anterior cruciate ligament (ACL) reconstruction. This growing interest stems from a better understanding of the rotational stability of the knee afforded by the identification of the anterolateral ligament. Previously, a residual abnormal pivot-shift test had been found after an anatomic single-band ...

BACKGROUND The Segond fracture is an avulsion-type fracture located on the anterolateral aspect of the tibia associated with a ligament recently termed the anterolateral ligament. This injury has been described as pathognomonic for an anterior cruciate ligament (ACL) tear and is associated with a higher grade pivot shift. PURPOSE To present and report 2-year clinical outcomes of a surgical te...

BACKGROUND A subset of patients have clinical internal and/or external knee rotational instability despite no apparent injury to the cruciate or collateral ligaments. PURPOSE/HYPOTHESIS The purpose of this study was to assess the effect of sequentially cutting the posterolateral, anterolateral, posteromedial, and anteromedial structures of the knee on rotational stability in the setting of in...
