Current Concepts in the Recognition and Treatment of Posterolateral Corner Injuries of the Knee

Comparative Analysis of the Structural Properties of the Collateral Ligaments of the Human Knee

“…Nonetheless, the findings of the current study highlight the importance of considering the structural stiffness of the collateral ligaments in the reconstruction and rehabilitation of the collateral ligaments of the knee, particularly in isolated ruptures, in which graft materials that are significantly stiffer than ligament are typically used. As noted by Lunden et al, 22 a firm understanding of the relative biomechanical properties of the collateral ligaments is essential for successful rehabilitation outcomes.…”

“…1 Concomitant injury to the posterolateral structures is often unrecognized in patients with multiple ligament or combined ligament disruptions. 12,22 Abnormal varus laxity arising subsequent to injuries of the LCL and other posterolateral structures has been shown to increase stress on cruciate ligament grafts, and has been implicated as one of the causes of failed cruciate ligament reconstructions. 12,19 Unlike the MCL, animal models have demonstrated that the LCL heals poorly when torn, 20 and, consequently, surgical repair or reconstruction of the LCL is often advocated with acute grade III injuries, particularly when multiple posterolateral structures are involved.…”

Functional Movement Analysis in the Differential Diagnosis of a Patient with a Posterolateral Corner Knee Injury

“…34 Their main role is to prevent excessive knee varus, tibial external rotation and posterolateral rotation. 35,36 Though it is unclear from the description of the original injury, this patient may have injured her PLC, PFL and popliteus tendon with a similar knee varus and tibial external rotation overload, either from the lateral kick or the lateral lunge. Patients who have suffered an injury to their posterolateral corner commonly present with altered gait mechanics, however a recognizable pattern has not yet been reported.…”

Managing Knee Injuries: Keeping Up With Changes

“…Despite the fact that MCL injuries tend to heal relatively well, there has been growing interest in the past few years in better understanding the function of the various sections of the MCL and how to better manage more serious, recalcitrant, or chronic injuries to that structure. The article by LaPrade and Wijdicks 10 provides a needed update on the MCL, which, together with a previous article on the management of posterolateral corner injuries of the knee, including the lateral collateral ligament (LCL), 12 should help the clinician better understand the function of these complex structures (the MCL and LCL), which have been relatively ignored for too long.…”
