PURPOSE This study evaluated different fibular-based reconstruction techniques for grade III posterolateral corner (PLC) injuries. METHODS Seven fresh-frozen cadaveric knees were used in this study. A surgical navigation system was used to determine varus opening and external rotation at 0 degrees , 30 degrees , and 60 degrees with a 9.8-Nm varus stress and 5-Nm external rotation stress appli...

BackgroundAnkle sprains are one of the most common injuries amongst general population and affect all spectrums activity levels. While anterior talofibular calcaneal fibular ligaments prevalently injured during there instances when chronic lateral ankle instability leads to rotational attenuate deltoid ligament. The few literature that exists concerning medial ligament reconstruction focus on a...

PURPOSE The purpose of this study was to investigate the functional and clinical outcomes of a consecutive series of patients who underwent fibular collateral ligament (FCL) and posterolateral corner (PLC) reconstruction by use of a single Achilles tendon allograft construct. METHODS Patients were identified through prospective sports medicine databases at 2 academic institutions. Only patien...

OBJECTIVE To determine whether positioning of the tibia affects the degree of tibial external rotation seen during a dial test in the posterior cruciate ligament (PCL)-posterolateral corner (PLC)-deficient knee. DESIGN Laboratory investigation. SETTING Biomechanics laboratory. HYPOTHESIS An anterior force applied to the tibia in the combined PCL-PLC-deficient knee will yield increased tib...

A 30-year-old male was involved in a car accident. Radiographs revealed a depressed marginal fracture of the medial tibial plateau and an avulsion fracture of the fibular head. Magnetic resonance imaging showed avulsion fracture of Gerdy's tubercle, injury to the posterior cruciate ligament (PCL), posterior horn of the medial meniscus, and the attachments of the lateral collateral ligament and ...

Chronic Lateral Collateral Injuries Lateral collateral ligament (LCL), popliteus tendon and popliteo-fibular ligament (PFL) are the main static stabilizers on the lateral side of the knee and resist abnormal varus and external rotation. Isolated injuries of the lateral stabilizing structures are rare and most of the injuries are associated with damage to the ACL or PCL. Unrecognized posterolate...

The ideal management of the dislocated knee remains controversial. These injuries often can be elusive; a significant number of dislocated knees spontaneously reduce and appear relatively benign on routine radiographs. A high index of suspicion, based on the mechanism of injury, soft-tissue assessment of the limb, and the level of knee instability should alert the physician to the possibility o...

The lateral aspect of the knee is stabilized by a complex arrangement of ligaments, tendons, and muscles. These structures can be demonstrated with routine spin-echo magnetic resonance (MR) imaging sequences performed in the sagittal, coronal, and axial planes. Anterolateral stabilization is provided by the capsule and iliotibial tract. Posterolateral stabilization is provided by the arcuate li...
